What to look out for

The checks worth doing on a Mitsubishi Outlander before you hand over any money. Every documented fault is listed below, each with its own page.

  • Serious issue

    Confirm full CVT fluid change history with receipts.

    See why

    Jatco JF011E CVT primary pulley bearing failure

    The Jatco JF011E CVT (also known as RE0F09A) fitted to 2.4L Outlanders uses a push-type steel belt running on variable-width primary and secondary pulleys. The primary pulley radial bearing is undersized for the side-loading forces generated under sustained high-torque clamping. Bearing fatigue causes spalling, releasing metallic debris that contaminates CVT fluid and scores the pulley cone surfaces. This accelerates belt microslip, causing exponential wear. Most owners service at petrol engine intervals (10,000km) rather than the mandated 40,000km CVT fluid change, allowing fluid thermal degradation that further reduces valve-body clamping pressure. The same JF011E unit is fitted to Nissan Qashqai J10 and Renault Koleos, confirming the design-level deficiency across platforms.

    What you would notice

    • Shudder or vibration during light throttle acceleration at 40-80km/h
    • Whining noise that increases proportionally with road speed
    • Hesitation or rubber-band lag when pulling away from rest
    • Slipping sensation under hard acceleration uphill
    • Transmission fault light with codes P0868, P0776, or P0777

    Typically $3,500–$8,500 to put right.

  • Serious issue

    Drain and examine the engine oil for silver-grey swarf.

    See why

    4B11 Balance Shaft Oil Pump Failure — Engine Oil Starvation

    The 4B11 2.0-litre turbocharged engine uses a secondary balance shaft module that contains a small oil pump supplying oil pressure to the balance shaft bearings. The balance shaft module drive chain and sprocket are prone to accelerated wear, and the internal oil pump within the module can fail, causing localised oil starvation to the balance shaft bearings. In severe cases the balance shaft seizes, destroying the module and sending metal debris into the main oil circuit, leading to rapid bearing failure throughout the engine. This is an intrinsic design weakness of the 4B11 shared with the Lancer Evolution X and Eclipse Cross predecessors; Mitsubishi issued a Technical Service Bulletin (TSB) and revised the module design mid-production run.

    What you would notice

    • Low oil pressure warning light illuminating at idle or low speed
    • Metallic silver-grey particles or swarf visible when draining engine oil
    • Rumbling or rattling noise from lower engine that increases with engine speed and diminishes at higher oil pressure
    • Engine bearing knock progressing to rod knock in advanced cases

    Typically $1,800–$6,500 to put right.

  • Serious issue

    Ask for a dated/odometer-stamped receipt for the last timing belt, tensioner and water pump replacement; if none exists, budget to do it immediately.

    See why

    Timing belt neglect on interference 4G6 engine (snapped belt destroys engine)

    The first-generation Airtrek/Outlander (chassis ZE/ZF) uses the belt-driven 4G63, 4G64 or 4G69 four-cylinder, all of which are interference engines. Mitsubishi specifies timing-belt replacement at roughly 100,000 km or 5-7 years, and if the belt snaps the pistons strike open valves, causing bent valves or catastrophic engine damage. Many older JDM imports arrive in NZ with no verifiable belt-change history, so the interval must be assumed overdue until proven. On the turbo 4G63T a leaking front crank seal can also contaminate and prematurely fail the belt.

    What you would notice

    • No service record of a timing belt change
    • Engine cranks but will not start after belt failure
    • Rattling or squealing from the front timing cover
    • Oil weeping from behind the timing cover (front crank seal)

    Typically $500–$1,200 to put right.

  • Serious issue

    During a sustained motorway test drive check for EV system warning lamps activating.

    See why

    PHEV Front Motor Inverter Overheating — Limp Mode Fault

    The front motor inverter unit on GF7W Outlander PHEVs can overheat during sustained high-speed motorway driving, repeated hill climbs, or towing at elevated power demand. When the inverter coolant loop fails to maintain temperature below the protection threshold, the Battery/EV system enters a thermal protection mode that disables the front electric motor and restricts overall vehicle power to a limp-home state. The fault is associated with inverter coolant pump degradation and partial blockage of the dedicated inverter cooling circuit.

    What you would notice

    • EV system or hybrid warning lamp illuminating during sustained motorway driving or repeated hill climbs, accompanied by a noticeable loss of power
    • Vehicle entering limp mode with reduced throttle response, the combustion engine taking over entirely while EV system is disabled until the inverter cools

    Typically $1,200–$6,500 to put right.

  • Serious issue

    Inspect the ball joint dust boots for cracking, tears, or missing grease — a compromised boot accelerates joint wear.

    See why

    Front Lower Arm Ball Joint Separation

    The front suspension lower control arm ball joints on Outlanders can develop insufficient retention of the ball stud within the joint housing due to wear of the polyurethane socket material and degradation of the dust boot seal. Contamination from water and road grit accelerates socket wear. In advanced cases the ball stud can partially or fully disengage from the housing, causing sudden and catastrophic loss of steering and wheel alignment. This failure mode prompted Mitsubishi to issue a safety recall across multiple markets including New Zealand.

    What you would notice

    • Clunking sound from the front suspension over bumps or during steering input, originating from the lower arm area
    • Vague or wandering steering with occasional sudden lateral pulling, in severe cases complete loss of directional control due to ball stud disengagement

    Typically $350–$900 to put right.

  • Serious issue

    Inspect the front suspension crossmember on a hoist for scale, holes, or prior repair, and have Mitsubishi check the VIN for applicable campaign work.

    See why

    Front crossmember corrosion safety campaign

    Mitsubishi campaign SR-16-003 and Transport Canada recall 2016317 concern corrosion of the front suspension crossmember on certain first-generation Outlanders. Severe corrosion can affect lower-control-arm attachment, so a vehicle from a corrosive environment requires a proper underbody inspection. Check local VIN eligibility because this campaign is market-specific.

    What you would notice

    • Heavy rust or perforation at the front subframe
    • Loose or noisy front suspension
    • No campaign completion record

RareEngine

Can't confirm for this car

Mitsubishi recall material for early 2003 Outlanders describes a throttle-body icing condition in specified production vehicles. This is not a universal generation fault: confirm the build date, market, and VIN campaign status before treating it as applicable.

Symptoms to notice

  • Abnormal throttle response in freezing conditions
  • No record of the relevant safety campaign
  • Early-2003 production vehicle

What to check

Confirm the build date and ask Mitsubishi to check the VIN against recall records; have a technician assess any irregular throttle response.

Where to look: Throttle body and engine-management system

Ask the seller

  • “Was the throttle-body icing recall completed?”
  • “Can a Mitsubishi dealer verify campaign eligibility by VIN?”

05Jatco CVT Shudder, Overheating and Premature Failure

06CVT Judder and Shudder Under Light Acceleration

petrol2006–2012Transmission
CommonTransmission $300–$7,500 to fix

Can't confirm for this car

Outlander variants fitted with the INVECS-III CVT (Continuously Variable Transmission) are prone to a low-speed judder or shudder sensation felt through the drivetrain during light throttle acceleration from a standstill, typically in the 15–40 km/h range. The root causes are degraded CVT fluid losing its friction modifier properties (the fluid has a short effective life of approximately 40,000–60,000 km in real-world use despite Mitsubishi's longer nominal interval), wear on the torque converter lock-up clutch, and belt-pulley slip during the ratio change. Mitsubishi issued a revised CVT fluid specification and updated fluid change intervals in response. Left unaddressed, the condition accelerates wear on the primary and secondary pulley faces and the push-belt assembly, leading to CVT replacement.

Symptoms to notice

  • Shudder or judder sensation through the body and drivetrain under gentle acceleration between 15 and 40 km/h
  • Judder absent under firm or wide-open throttle acceleration but present at partial throttle
  • CVT fluid discoloured brown or with a burnt smell when checked
  • Transmission warning light or CVT-related fault codes stored in the TCU

What to check

During a test drive, accelerate gently from a standstill to 40 km/h on flat ground and feel for a rhythmic shudder or judder through the seat and pedals. If present at light throttle but absent under firm acceleration, this is the classic CVT judder signature. Check the CVT fluid via the dipstick or fill plug — it should be pink/red and odourless; brown, burnt-smelling fluid indicates overdue service and potential damage. Confirm whether the CVT fluid has been changed within the last 40,000 km. Have the vehicle scanned for CVT fault codes (TC1 series).

Where to look: INVECS-III CVT unit mounted transversely behind the engine, identifiable by the flat-sided alloy casing and single selector cable

Parts involved: Torque converter, CVT belt and pulleys, Clutch.

Ask the seller

  • “Has the CVT fluid ever been changed, and do you have a receipt showing the work?”
  • “Does the transmission feel smooth during light acceleration from a stop, or is there any shuddering?”
  • “Has the transmission warning light ever come on?”

074B11/4B12 Excessive Engine Oil Consumption

Check the engine oil dipstick carefully — note the level and condition.petrol2012 onwardEngine
OccasionalEngine $2,000–$7,000 to fix

Can't confirm for this car

The 4B11 2.0L and 4B12 2.4L four-cylinder engines used in the GF/GG and ZK/ZL Outlander can consume engine oil at rates above 1 litre per 5,000 km without external leaks. Piston ring seal degradation allows oil to pass into the combustion chamber, burning it off as light blue smoke on start-up and acceleration. Owners who do not check oil between services risk running low and accelerating main bearing or VVT actuator wear. Mitsubishi issued customer satisfaction campaigns for some build ranges but no formal recall.

Symptoms to notice

  • Oil level drops 0.5–1.5 litres between 5,000 km services without visible leaks
  • Light blue-grey smoke on cold start or under heavy acceleration
  • Spark plugs fouled with oil deposits
  • PCV system valve clogged with oily sludge

What to check

  1. Check the engine oil dipstick carefully — note the level and condition.
  2. Examine the PCV hose and valve for oil sludge.
  3. Ask the seller how often oil is topped up between services and whether they check it regularly.
  4. If a workshop inspection is possible: Inspect spark plugs for oil fouling (require removal or borescope).

Where to look: Engine internals — piston rings and valve stem seals

Ask the seller

  • “How often is engine oil topped up between services?”
  • “Has the vehicle ever shown blue smoke on start-up or acceleration?”
  • “Has the PCV system or valve cover gasket been inspected or replaced?”

10Rear AWD Coupling Unit Failure

Locate the rear coupling unit on the rear axle and check the fluid drain plug for metallic particles on the magnetic tip.petrol2007–2021Transmission
CommonTransmission $1,800–$5,500 to fix

Can't confirm for this car

The Outlander's electronically-controlled rear coupling unit (part of the AWC all-wheel-control system) uses a wet multi-plate clutch that relies on purpose-specific coupling fluid changed every 40,000–50,000 km. When the fluid is neglected, clutch plate friction material breaks down, contaminating the fluid and causing the coupling to drag or slip. Symptoms include binding in tight turns, a grinding vibration at highway speed, and eventual loss of rear-wheel drive. Coupling replacement or rebuild is the required fix. This is consistently one of the costliest mechanical failures on used four-wheel-drive Outlanders.

Symptoms to notice

  • Grinding or vibration sensation from the rear axle at highway speeds
  • Binding or hopping sensation when turning tightly at low speed
  • 4WD warning light illuminated on dash
  • Rear coupling fluid dark brown or black with metallic debris

What to check

  1. Locate the rear coupling unit on the rear axle and check the fluid drain plug for metallic particles on the magnetic tip.
  2. Drive a slow figure-eight on a flat surface — any binding indicates coupling drag.
  3. Scan for DTCs C1234 or C1235 (rear coupling slip).
  4. Confirm coupling fluid service history.

Where to look: Rear axle, between rear prop shaft and rear differential

Parts involved: Clutch.

Ask the seller

  • “Has the rear AWD coupling fluid ever been changed and at what odometer?”
  • “Has a 4WD warning light or binding in tight turns been noted?”
  • “Has the vehicle been used off-road or in sustained 4WD operation?”

12All-Wheel Drive Transfer Case Bearing Noise

2006–2012Transmission
OccasionalTransmission $1,200–$4,500 to fix

Can't confirm for this car

Outlander models fitted with the Active Stability and Traction Control (ASTC) Super-All Wheel Control (S-AWC) or conventional 4WD transfer case develop bearing wear in the transfer case with age and high mileage. The transfer case front output bearing and the internal chain-drive assembly are susceptible to wear when transfer case oil has not been changed at the recommended interval or when the vehicle is used in wading or prolonged 4WD conditions that accelerate internal wear. The resulting bearing noise presents as a rumbling or droning sound that changes frequency with road speed (not engine speed), and in advanced cases a grinding noise appears under power. Left unaddressed, bearing failure can cause transfer case seizure and drivetrain damage extending to the front and rear prop shafts.

Symptoms to notice

  • Droning or rumbling noise from the centre of the drivetrain that increases proportionally with road speed, not engine speed
  • Grinding noise under load during acceleration, particularly when AWD is engaged
  • Transfer case oil contaminated with metallic particles when drained or inspected at the fill plug
  • Vibration through the centre console or floor under moderate to heavy acceleration

What to check

During the road test, hold a steady speed on a quiet road and listen for a droning or rumbling from the centre of the vehicle that tracks with road speed. Vary speed between 60–100 km/h and check whether the tone changes proportionally with speed (not engine revs) — this identifies bearing noise rather than engine or exhaust noise. With the vehicle raised, check for transfer case oil leaks at the output flanges and inspect the oil level via the fill plug. Check the condition of the transfer case fluid — it should be clean and transparent; dark, metallic-contaminated fluid indicates internal wear. Request service records showing transfer case oil changes.

Where to look: Transfer case mounted at the rear of the transmission, identifiable by the front prop shaft exit on all-wheel drive variants

Parts involved: Transfer case.

Ask the seller

  • “Has the transfer case oil ever been changed, and when?”
  • “Is there any droning or rumbling from beneath the vehicle at highway speed?”
  • “Has the vehicle ever been used in water crossings or prolonged off-road conditions?”

13CW5W Front Transfer Case Chain Rattle

The front transfer unit on CW5W Outlanders uses a roller chain to distribute torque to the front axle.petrol2006–2012Transmission
CommonTransmission $800–$3,500 to fix

Can't confirm for this car

The front transfer unit on CW5W Outlanders uses a roller chain to distribute torque to the front axle. This chain and its tensioner are prone to developing a metallic rattle at idle and low speed, particularly when the transmission oil in the transfer case is cold or has degraded. The rattle originates from chain slack on the unloaded side at low oil viscosity. In severe cases the chain stretches beyond the tensioner's range, causing intermittent 4WD engagement failures and wear debris contaminating the transfer fluid.

Symptoms to notice

  • Metallic chain rattle audible from the transmission tunnel area at cold idle, fading partially once the transfer fluid warms
  • 4WD system warning light illuminating under hard acceleration or during AWD mode engagement, indicating chain slip or tensioner over-extension

What to check

  1. Listen for a chain rattle from the transfer case area at cold idle — distinct from engine noise, louder immediately after a cold start and typically reducing once warm.
  2. Request transfer case fluid service history.
  3. Check 4WD engagement function across all modes.
  4. Severe cases show 4WD system warning lamp.
  5. If a workshop inspection is possible: Drop the transfer case fluid and inspect for metallic particles or swarf.

Where to look: Front transfer case unit, mounted behind the main transmission

Parts involved: Transfer case.

Ask the seller

  • “Does the car make a rattling noise from the transmission area on cold starts?”
  • “Has the transfer case fluid ever been changed?”
  • “Has the 4WD warning light ever come on?”

15HV Battery Thermal Management Coolant Pump Failure

Listen for the battery coolant pump operating (a faint hum from under the floor) with the vehicle in READY mode and climate system active.hybrid2021–2024Cooling
RareCooling $900–$2,800 to fix

Can't confirm for this car

The GN PHEV uses a dedicated electric coolant pump to circulate coolant through the HV battery thermal management circuit. Failure of this pump — through bearing seizure, impeller wear, or electrical fault — causes the HV battery to lose active thermal regulation. In hot ambient conditions this manifests as rapid battery temperature rise, forced charge rate reduction, and ultimately a thermal protection shutdown limiting vehicle performance. In cold conditions the pack cannot be pre-conditioned. Multiple GN PHEV owners have documented this failure via warning codes and elevated battery temperatures on third-party monitoring apps.

Symptoms to notice

  • HV battery temperature warning or thermal management fault lamp illuminated during or after charging
  • Charge rate significantly throttled or charge session aborted on warm days
  • EV performance or acceleration noticeably reduced during hot weather despite adequate battery charge
  • HV battery coolant reservoir level low with no visible external leak (internal pump seal failure)
  • Fault codes related to battery thermal management or cooling circuit flow faults on diagnostic scan

What to check

  1. Listen for the battery coolant pump operating (a faint hum from under the floor) with the vehicle in READY mode and climate system active.
  2. Check coolant level in the dedicated pink/red HV battery cooling circuit reservoir (separate from engine coolant).
  3. If a workshop inspection is possible: On a diagnostic scan, monitor the HV battery coolant pump operating status and battery inlet/outlet coolant temperature differential during a charge session — a functioning pump should show active circulation with a temperature differential of 2–5°C.

Where to look: Electric coolant pump and HV battery cooling circuit running along the underfloor HV battery perimeter

Parts involved: Water pump.

Ask the seller

  • “Has the vehicle ever shown a battery temperature warning or had charging throttled or cut short during warm weather?”
  • “Has either of the coolant circuits — engine or HV battery — ever needed a top-up or had work done?”
  • “Has the vehicle been operated in consistently hot conditions such as prolonged summer parking without shade?”

174B12 MIVEC Timing Actuator Rattle at Cold Start

Cold-start the engine from fully cold and listen immediately for a metallic rattle from the top of the engine.petrol2006–2012Engine
CommonEngine $400–$2,200 to fix

Can't confirm for this car

The 4B12 MIVEC engine uses oil-pressure-driven variable valve timing actuators on both the intake and exhaust camshafts. At cold start, before oil pressure builds, the actuator vanes can rattle briefly against their lock pins. While brief rattle of under five seconds is considered normal, vehicles that have experienced extended oil change intervals or that sit unused for several weeks develop persistent rattle lasting 15 seconds or more, indicating actuator wear and degraded oil retention in the VVT galleries. Continued operation with worn actuators causes MIVEC DTCs and reduced fuel economy.

Symptoms to notice

  • Loud metallic rattling from the top of the engine at cold start lasting more than 5 seconds, reducing as oil pressure builds
  • P0011 or P0021 MIVEC cam timing fault codes stored, indicating the actuator is not holding the commanded cam position under oil pressure

What to check

Cold-start the engine from fully cold and listen immediately for a metallic rattle from the top of the engine. Time the duration — over 5 seconds is abnormal, over 15 seconds indicates actuator wear. Check for DTCs P0011 (intake cam timing over-advanced) or P0021 (exhaust cam timing over-advanced) which confirm actuator malfunction. Check oil viscosity and condition — thin or degraded oil accelerates actuator wear.

Where to look: Top of engine, MIVEC timing actuators on intake and exhaust camshafts

Ask the seller

  • “Does the engine rattle on cold start and for how long?”
  • “What oil viscosity is used and how frequently is the oil changed?”
  • “Have any engine management lights appeared related to timing or MIVEC?”

18AWD Transfer Case Electronic Actuator Failure

Verify the AWD warning lamp status.2006–2012Transmission
OccasionalTransmission $700–$2,000 to fix

Can't confirm for this car

The CW Outlander uses an electronically controlled rear-drive coupling (AYC/AWD transfer unit) that engages the rear driveshaft via an electrically-driven actuator. The actuator motor and its reduction gear set are susceptible to water ingress, internal corrosion, and gear tooth wear, causing the unit to fail in the disengaged position. When this occurs the vehicle reverts to permanent front-wheel drive without warning, and the AWD warning lamp illuminates. The failure is particularly prevalent on vehicles that have been exposed to road salt or deep water wading, as the actuator housing seal degrades over time and the electronic motor windings corrode internally.

Symptoms to notice

  • AWD warning light illuminated permanently on the instrument cluster
  • Vehicle pulls under hard cornering consistent with front-wheel-drive-only behaviour when AWD should be active
  • Scan tool reveals no torque delivery to the rear coupling despite commanding AWD engagement
  • Clicking or grinding noise from the rear of the vehicle when attempting to engage AWD from 2WD mode

What to check

  1. Verify the AWD warning lamp status.
  2. Check for fault codes C1608 or C1610 (AWD actuator range/performance).
  3. Inspect the actuator housing for corrosion and the wiring harness connector for green oxidation or broken terminals.
  4. If a workshop inspection is possible: Use a Mitsubishi-compatible scan tool (MUT-III or equivalent) to command the AWD coupling to engage and confirm actual torque transfer to the rear wheels on a 4WD dynamometer or split-mu surface test.

Where to look: AWD transfer case actuator mounted on the rear differential/coupling unit beneath the rear of the vehicle

Parts involved: Transfer case.

Ask the seller

  • “Has the AWD warning light ever come on, even intermittently?”
  • “Has the AWD system been tested to confirm it actually engages the rear wheels?”
  • “Has the vehicle been used off-road or driven through water crossings?”

01PHEV Front Motor Inverter Overheating — Limp Mode Fault

During a sustained motorway test drive check for EV system warning lamps activating.hybrid2013 onwardElectrical
OccasionalElectrical $1,200–$6,500 to fix

Can't confirm for this car

The front motor inverter unit on GF7W Outlander PHEVs can overheat during sustained high-speed motorway driving, repeated hill climbs, or towing at elevated power demand. When the inverter coolant loop fails to maintain temperature below the protection threshold, the Battery/EV system enters a thermal protection mode that disables the front electric motor and restricts overall vehicle power to a limp-home state. The fault is associated with inverter coolant pump degradation and partial blockage of the dedicated inverter cooling circuit.

Symptoms to notice

  • EV system or hybrid warning lamp illuminating during sustained motorway driving or repeated hill climbs, accompanied by a noticeable loss of power
  • Vehicle entering limp mode with reduced throttle response, the combustion engine taking over entirely while EV system is disabled until the inverter cools

What to check

  1. During a sustained motorway test drive check for EV system warning lamps activating.
  2. Scan for P0A93 (inverter cooling system performance) or P1E00 (front motor system fault).
  3. Inspect the inverter cooling circuit — feel the EV coolant reservoir and hoses for correct coolant level and flow.
  4. Verify no stored thermal overtemperature events in the EV system freeze frame data.
  5. If a workshop inspection is possible: Check inverter coolant pump operation with a scan tool actuator test.

Where to look: Front motor inverter unit, engine bay left side near the high-voltage junction box

Parts involved: Water pump.

Ask the seller

  • “Has the EV or hybrid warning light ever come on during a long motorway drive?”
  • “Has the car ever gone into limp mode or reduced power mode?”
  • “Has the inverter coolant circuit ever been serviced or the EV coolant pump replaced?”

02High-Voltage Traction Battery Cell Degradation

Acceptable SOH should be above 80% for a 3-year-old vehicle.hybrid2021–2024Electrical
OccasionalElectrical $8,000–$22,000 to fix

Can't confirm for this car

The 20 kWh (usable ~17 kWh) lithium-ion HV traction battery in the GN-generation PHEV has shown faster-than-expected capacity loss in warmer climates and in vehicles used predominantly on short trips where the pack rarely reaches full thermal conditioning. Affected owners report EV-only range dropping from the rated ~84 km (WLTP) to 50–60 km within 3–4 years. Mitsubishi's battery management system can mask gradual cell imbalance until a significant capacity event occurs. No blanket recall has been issued but NHTSA complaint data and MiOutlander owner forums document the pattern consistently across GN PHEVs produced 2021–2024.

Symptoms to notice

  • EV-only range noticeably shorter than the rated figure even after a full charge
  • Dashboard EV range estimate fluctuates erratically during a single trip
  • Battery charge indicator drops rapidly during moderate motorway driving in EV mode
  • Charging session terminates early without reaching 100% or takes unusually long
  • MIL or HV system warning lamp illuminated with fault codes P0A7F or P0A80

What to check

Acceptable SOH should be above 80% for a 3-year-old vehicle. A cell voltage spread greater than 0.05 V at rest indicates imbalance. Also check that the EV range estimate on a full charge matches the model year's rated figure within 20%. If a workshop inspection is possible: Connect a Mitsubishi-compatible diagnostic tool (or MUT-III) and read the HV battery state-of-health (SOH) percentage and individual cell voltage spread at rest.

Where to look: HV battery pack mounted under the cabin floor between the front and rear axles

Ask the seller

  • “Can you show a diagnostic readout of the HV battery state-of-health and current EV range on a full charge?”
  • “Has the vehicle ever had an HV battery-related fault code or been into a dealer for a battery software update?”

OccasionalElectrical $3,500–$9,000 to fix

Can't confirm for this car

The front-axle integrated electric motor/generator unit on the GN PHEV S-AWC has been documented producing a pronounced whining or grinding noise during low-speed EV operation and regenerative braking. The failure mode is bearing wear or preload loss in the motor's rotor bearings, typically emerging after 40,000–80,000 km. Forum and dealer service records indicate Mitsubishi issued an internal service advisory and in some cases replaced the front motor assembly under warranty. If left unaddressed the bearing can seize, converting a noise fault into a drivability failure.

Symptoms to notice

  • High-pitched whine audible from the front of the vehicle during EV-only low-speed driving
  • Noise increases or changes pitch during regenerative braking application
  • Vibration felt through the floor or steering column at speeds below 50 km/h in EV mode
  • Front motor temperature warnings or motor overcurrent fault codes on diagnostic scan
  • Noise absent when combustion engine is running but returns when engine switches off

What to check

Drive the vehicle at 10–40 km/h in pure EV mode with the combustion engine off and windows up. Listen for a steady high-pitched whine or intermittent grinding from the front drivetrain area. Apply light regenerative braking and note whether the noise intensifies. If a workshop inspection is possible: Have the front motor temperature and motor current draw checked for abnormal values on a diagnostic scan tool.

Where to look: Front electric motor/generator unit integrated with the front transaxle, engine bay left-centre

Ask the seller

  • “Has any whining or grinding noise ever been reported from the front of the vehicle, particularly in EV mode?”
  • “Has the front electric motor or transaxle been inspected or replaced under warranty?”
  • “Can we do a test drive at low speed in full EV mode so I can listen for drivetrain noise?”

RareElectrical $3,000–$8,500 to fix

Can't confirm for this car

The onboard AC charger module, which converts mains AC power to DC for charging the HV traction battery, has been reported failing on GN PHEVs. Affected vehicles accept a charge cable but the charge process does not initiate or terminates within minutes with an error on the Charge/EV status display. In some cases the OBC failure is preceded by intermittent charging faults that resolve and recur before a hard failure. NHTSA complaint filings and owner forum posts confirm OBC failure as a distinct fault separate from external EVSE or cable issues. The OBC module on this generation requires dealer-level diagnostics and typically a full module replacement.

Symptoms to notice

  • Charge cable plugged in but dashboard shows no active charging and the charge lamp does not illuminate
  • Charging initiates then stops within 1–5 minutes without reaching target state of charge
  • Error or fault indicator on the charge port light or infotainment charge screen with no clear cause
  • AC charging fails consistently while DC fast charging (CHAdeMO) still functions normally
  • Fault codes P1E00, P0D73, or OBC-specific codes retrieved on diagnostic scan

What to check

  1. Test AC charging using a known-good EVSE (home wallbox or public AC charger) with both a Type 1 J1772 and Type 2 cable if applicable.
  2. Confirm the charge indicator on the dashboard initiates within 60 seconds of plugging in.
  3. Verify charge session logs via the Mitsubishi remote app if the vehicle is connected.
  4. If a workshop inspection is possible: Use a diagnostic scan tool to check for OBC-specific fault codes (P1E00-series or manufacturer HVAC charging codes).

Where to look: Onboard charger module integrated within the Power Drive Unit (PDU), engine bay

Ask the seller

  • “Has the vehicle ever failed to initiate or complete an AC charge session, or shown a charging fault on the dash?”
  • “Does the vehicle successfully charge on both standard AC (home wall outlet or wallbox) and DC fast chargers?”
  • “Has any work been done on the charging system, charge port, or related modules?”

06DC-DC Converter Failure Causing 12V System Collapse

Measure the 12V battery voltage with the vehicle in READY mode — it should be 13.8–14.5 V if the DC-DC converter is functioning.hybrid2021–2024Electrical
RareElectrical $2,800–$7,500 to fix

Can't confirm for this car

The DC-DC converter, which steps down the 330V+ HV traction battery to charge the conventional 12V auxiliary lead-acid battery, has been reported failing on GN PHEVs. When the converter fails the 12V system is no longer replenished from the HV pack. The 12V battery drains, causing a cascade of electrical warnings, loss of powered accessories, and ultimately a no-start condition even with a full HV battery. This fault is well documented across PHEV platforms and specific cases on the GN Outlander PHEV have been filed with NHTSA. Replacement requires the converter module and typically recalibration of the HV management system.

Symptoms to notice

  • Multiple electrical warning lights illuminate simultaneously with a full HV battery charge displayed
  • 12V battery repeatedly drains despite normal usage patterns and a recently replaced 12V battery
  • Vehicle enters a no-start condition — READY mode not achievable — despite HV battery showing charge
  • Audible relay clicking or power cycling of infotainment and climate systems
  • Fault codes P0D3B or related HV-to-12V conversion errors stored in the ECU

What to check

Measure the 12V battery voltage with the vehicle in READY mode — it should be 13.8–14.5 V if the DC-DC converter is functioning. A reading below 13.0 V in READY mode indicates a non-charging condition. Retrieve fault codes; P0D3B, P0D0D, or manufacturer-specific HV interlock codes point to DC-DC converter faults. Check service records for any prior 12V battery replacements that may have masked an underlying converter fault.

Where to look: DC-DC converter module within the Power Drive Unit (PDU) assembly in the engine bay, forward of the HV battery

Parts involved: 12V battery.

Ask the seller

  • “Has the vehicle ever failed to enter READY mode or had a situation where multiple warning lights came on with the HV battery still charged?”
  • “Has the 12V auxiliary battery been replaced, and if so, why?”
  • “Are there any stored or previously cleared fault codes related to the high-voltage charging system?”

07PHEV generator overtemperature from short charge cycles

Check the HV battery cooling air intake located in the boot area for blockages from luggage or debris.hybrid2021 onwardElectrical
OccasionalElectrical $1,800–$7,500 to fix

Can't confirm for this car

The GN Outlander PHEV 2.4-litre Atkinson-cycle petrol generator (MG1) can develop an overtemperature fault when subjected to repeated short charge cycles in close succession — for example consecutive short motorway runs where a depleted high-voltage battery demands maximum generator output with insufficient thermal recovery time between events. The generator stator windings and associated power electronics cannot dissipate accumulated heat adequately, causing the hybrid ECU to log MG1 overtemperature fault codes and limit or disable generator charging output. The vehicle may enter series-hybrid-restricted or charge-limited mode with notably reduced power. The condition is exacerbated by high ambient temperatures and is most frequently triggered by fleet or rideshare usage patterns.

Symptoms to notice

  • EV or HEV warning light illuminated on instrument cluster
  • Reduced power or restricted hybrid operation mode engaged
  • Generator and petrol engine run continuously without effective HV battery charging
  • Elevated heat perceived from transmission tunnel or centre console area
  • Mitsubishi PHEV remote app displaying abnormal charge state or system warnings

What to check

  1. Check the HV battery cooling air intake located in the boot area for blockages from luggage or debris.
  2. Verify the HV battery cooling fan operates at all speed stages.
  3. Establish the vehicle's typical usage pattern — short repeated runs from a depleted battery state are the primary trigger.
  4. Request a Mitsubishi dealer check for applicable hybrid control ECU software calibration updates.
  5. If a workshop inspection is possible: Scan the hybrid ECU for stored fault codes relating to MG1 overtemperature or high-voltage system thermal events using a Mitsubishi-compatible diagnostic tool.

Where to look: Hybrid generator MG1 mounted to engine block, power electronics unit (PCU) in engine bay

Ask the seller

  • “Has the EV or HEV warning light ever illuminated?”
  • “How is the vehicle typically used — mostly short city trips or longer highway runs with a depleted battery?”
  • “Has the hybrid system ever entered a limited or restricted power mode?”
  • “Have any hybrid ECU software updates been applied at a Mitsubishi dealer?”

08Rear Electric Motor Output Shaft Seal Leak

Check the underside of the rear bumper apron and rear sub-frame crossmember for oil staining.hybrid2021–2024Electrical
OccasionalElectrical $1,200–$6,500 to fix

Can't confirm for this car

On S-AWC equipped GN PHEVs the rear electric motor drives the rear axle through a reduction gearset. The output shaft oil seal on this unit has been documented failing, allowing gear oil to leak past the seal and in some cases contaminate the electric motor windings. Forum reports and independent workshop reports from Australia and New Zealand confirm this failure, which typically becomes apparent between 30,000–70,000 km. Left unaddressed, oil intrusion into the motor can cause winding insulation breakdown and eventual motor failure, significantly escalating repair costs.

Symptoms to notice

  • Oil spots or film visible on the underside of the vehicle beneath the rear motor unit
  • Burnt oil smell from the rear underfloor, particularly noticeable after highway driving
  • Rear motor temperature warning or rear AWD system warning lamp illuminated
  • Rear traction noticeably reduced or AWD system entering limp mode with fault codes stored
  • Whining or roughness from the rear drivetrain that worsens progressively over weeks

What to check

  1. Check the underside of the rear bumper apron and rear sub-frame crossmember for oil staining.
  2. Confirm gear oil level in the rear motor reduction unit if accessible.
  3. Smell for burned gear oil under the rear of the vehicle after a road test.
  4. If a workshop inspection is possible: With the vehicle on a hoist, inspect the rear electric motor/reducer unit for oil residue or wet patches around the output shaft flanges and driveshaft connection points.

Where to look: Rear electric motor and reduction gearbox unit mounted on the rear sub-frame, inboard of the rear axle

Ask the seller

  • “Has the rear underfloor ever shown any signs of oil leakage, or has the rear motor area been inspected by a workshop?”
  • “Has the rear AWD system ever faulted, entered limp mode, or shown a warning light?”
  • “Has any work been done on the rear drive unit or its seals?”

09Electric Power Steering Rack Rattle and Loss of Assist

The CW Outlander uses a column-assist electric power steering system in which the EPS motor drives a worm gear coupled to the steering column.2006–2012Electrical
OccasionalElectrical $800–$2,500 to fix

Can't confirm for this car

The CW Outlander uses a column-assist electric power steering system in which the EPS motor drives a worm gear coupled to the steering column. Over time the gear mesh between the worm and sector can develop clearance due to wear, producing a rattle or knock transmitted directly through the steering wheel over rough surfaces. Separately, the EPS control unit can develop thermal faults or internal component failures that cause the power assist to cut out intermittently or permanently, leaving the driver with full manual steering effort at parking speeds — a significant safety concern. The EPS warning lamp illuminates when assist is lost, and the system defaults to manual operation.

Symptoms to notice

  • Rattle or knocking noise from the steering column when driving over rough or uneven road surfaces
  • EPS warning lamp illuminated on the instrument cluster, either permanently or intermittently
  • Sudden increase in steering effort requiring significantly more force to manoeuvre at low speed
  • Intermittent return of normal power assist that may lead the driver to initially dismiss the fault

What to check

With the engine running, turn the steering wheel slowly from lock to lock and listen for a rattle, clunk, or grinding noise from the steering column area. Test power assist by attempting a full-lock turn at walking pace — any noticeably high steering effort indicates partial or full loss of assist. Inspect the EPS wiring harness connector at the column for corrosion or pushed-back terminals. If a workshop inspection is possible: Check for EPS fault codes using a compatible scan tool (codes C1513, C1514 indicate motor or torque sensor faults).

Where to look: EPS assist motor and control unit on the steering column beneath the dashboard; steering rack in the engine bay behind the front crossmember

Parts involved: Steering rack.

Ask the seller

  • “Has the EPS warning light ever come on, even briefly?”
  • “Does the steering rattle or knock over bumps, particularly on rough roads?”
  • “Has the steering ever felt unexpectedly heavy or required unusual effort to turn?”

CommonElectrical $350–$1,100 to fix

Can't confirm for this car

The motorised charging port door on GF7W Outlander PHEVs uses a small electric actuator to open and close the flap on command from the key fob, dashboard button, or charging cable insertion. The actuator motor and its plastic gear train are exposed to weather and temperature cycles. Failure of the actuator leaves the charging port door stuck either open or closed. A door stuck closed prevents charging entirely; a door stuck open admits water to the charging socket area. Repeated partial failures manifest as slow or intermittent door operation before complete seizure.

Symptoms to notice

  • Charging port door failing to open or close on command from the key fob or interior switch, or operating intermittently with slow and grinding movement
  • Charging system warning message on the dashboard instrument cluster related to an inlet door fault, preventing the vehicle from accepting a charge

What to check

  1. Operate the charging port door open and close several times using the key fob and the interior button — it should move smoothly and fully seat in both positions without hesitation.
  2. Listen for grinding or slow motor operation indicating gear wear.
  3. Inspect the door surround for water ingress marks or corrosion around the charging socket.
  4. Check for fault codes related to the charging system inlet door in the PHEV EV module.

Where to look: Front charging port door actuator, located in the front bumper charging inlet assembly

RareBrakes $1,800–$5,500 to fix

Can't confirm for this car

The GN PHEV replaces a conventional vacuum brake booster with an electric brake booster (e-boost) system to maintain pedal assist without reliance on combustion engine vacuum. The electric pump within this system has been documented producing a grinding or whirring noise during initial brake application or when the pump cycles to maintain accumulator pressure. In more serious cases the pump motor has failed outright, triggering a brake system warning and reverting to manual (unassisted) braking requiring significantly higher pedal effort. NHTSA complaints from GN PHEV owners in 2022–2024 document both noise and hard-failure events.

Symptoms to notice

  • Grinding or whirring noise from the engine bay during the first few brake applications after starting
  • Brake pedal feels unusually hard and requires significantly more effort than normal to achieve deceleration
  • Brake system warning lamp or red brake warning illuminated on the instrument cluster
  • Brake pedal pulsates or has inconsistent feel between applications at low speed
  • Fault codes C1267 or related electric brake booster fault codes on diagnostic scan

What to check

With the vehicle in READY mode and stationary, apply and release the brake pedal several times and listen for any grinding, whirring, or cycling noise from beneath the bonnet on the driver's side. Apply the brake firmly and check for a solid, consistent pedal feel — sponginess or a brake warning lamp indicates a fault. Retrieve any stored brake system fault codes (C1xxx series). Note any brake warning or e-boost warning in the instrument cluster.

Where to look: Electric brake booster pump and accumulator unit in the engine bay, driver's side near the brake master cylinder

Ask the seller

  • “Has the brake pedal ever felt unusually hard or required much more effort than normal, or has a brake warning light appeared?”
  • “Has any grinding or whirring noise been noted from the engine bay when applying the brakes?”
  • “Has the vehicle had any brake system work, software updates, or brake booster components replaced?”

OccasionalSuspension $350–$900 to fix

Can't confirm for this car

The front suspension lower control arm ball joints on Outlanders can develop insufficient retention of the ball stud within the joint housing due to wear of the polyurethane socket material and degradation of the dust boot seal. Contamination from water and road grit accelerates socket wear. In advanced cases the ball stud can partially or fully disengage from the housing, causing sudden and catastrophic loss of steering and wheel alignment. This failure mode prompted Mitsubishi to issue a safety recall across multiple markets including New Zealand.

  • Vague or wandering steering with occasional sudden lateral pulling, in severe cases complete loss of directional control due to ball stud disengagement

What to check

Inspect the ball joint dust boots for cracking, tears, or missing grease — a compromised boot accelerates joint wear. With the front wheels elevated, grasp the wheel at 6 and 12 o'clock and test for vertical play in the ball joint. Any detectable movement is a rejection. Check for recall completion status — Mitsubishi dealers can confirm by VIN whether the recall replacement was performed.

CommonBody & Rust $800–$4,000 to fix

Can't confirm for this car

First-generation Outlanders (CU/CW platform) have thin steel stampings in the rear wheel arch lips, B-pillar lower sections, and rear sill areas that corrode through from the outside in. NZ and coastal AU conditions accelerate this significantly. Rust can penetrate into the structural sill, creating a WOF/roadworthiness failure. Poorly repaired arches with filler are common at point of sale, hiding active corrosion underneath.

Symptoms to notice

  • Bubbling or flaking paint along rear wheel arch lips
  • Visible rust holes or perforations in lower sill panel
  • Soft or flexible metal when pressed around arch edges
  • Filler visible under paint when arch is flexed or examined with a magnet

What to check

  1. Use a magnet to check for filler in rear arches and lower sills — the magnet will not stick to body filler.
  2. Inspect the inside of the rear wheel arch with a torch.
  3. Lift floor mats to check for rust on the inner sill where water collects.
  4. Check the spare wheel well for rust perforations.

Where to look: Rear wheel arches, lower B-pillar, rear sills, and spare wheel well

Parts involved: Body corrosion.

The hydraulic power steering rack fitted to GF3W/GG3W Outlanders is subject to internal seal degradation with age and mileage.2006–2012Suspension
CommonSuspension $600–$2,200 to fix

Can't confirm for this car

The hydraulic power steering rack fitted to GF3W/GG3W Outlanders is subject to internal seal degradation with age and mileage. The rack seals and O-rings harden and shrink over time, allowing power steering fluid to weep past the rack seals and accumulate on the inner tie rod boots, subframe, and underbody. In early stages the leak is minor and causes a low fluid warning; as seals deteriorate further the fluid loss rate increases, ultimately causing heavy steering, pump whine, and pump damage from cavitation. In cold conditions the leak is characterised by a distinctive steering groan on full lock that disappears once the fluid warms. New Zealand's climate range accelerates seal deterioration compared to the tropical markets these vehicles were often designed for.

Symptoms to notice

  • Oily residue visible on the steering rack, subframe, or inside the tie rod boots when inspected underneath
  • Power steering fluid level dropping without an obvious external spill — requires repeated top-ups
  • Steering groan or moan on full lock in cold conditions, disappearing after the fluid warms
  • Heavy or vague steering feel that worsens as fluid level drops

What to check

With the vehicle raised, inspect the inner surfaces of the front tie rod boots and the subframe directly beneath the steering rack for oily residue or fluid pooling. Check the power steering fluid reservoir level and note any fluid loss since the last top-up. On start-up in cooler conditions, turn the wheel to full lock and hold for 2–3 seconds in each direction — a pronounced moan or groan indicates low fluid or early pump cavitation from a leaking rack. A UV dye test in the power steering fluid can confirm the rack as the leak source versus pump or hose leaks.

Where to look: Hydraulic steering rack mounted transversely on the front subframe, with leak points at the rack end seals behind the inner tie rod boots and at the high-pressure line connections

Parts involved: Steering rack.

Ask the seller

  • “Has the power steering fluid level required topping up recently?”
  • “Is there any groaning or heaviness in the steering, especially when cold or at full lock?”
  • “Has the steering rack ever been resealed or replaced?”

06Rear Multi-Link Suspension Bush Collapse

Grip each link by hand and attempt to move it axially and radially — any movement beyond 1–2 mm indicates bush failure.2006–2012Suspension
CommonSuspension $500–$1,500 to fix

Can't confirm for this car

The CW Outlander rear suspension uses a multi-link arrangement with multiple rubber-bonded bushes in each trailing arm, toe link, and lateral link. Over time and with exposure to road oils, ozone, and load cycling, the rubber element within each bush delaminates from its steel inner sleeve or collapses radially, allowing the link geometry to move outside its design parameters. This causes the rear wheels to adopt incorrect toe and camber angles under load, producing progressive oversteer tendencies, accelerated tyre wear, and an inability to hold a stable wheel alignment. Vehicles with collapsed rear bushes are unsafe for highway driving at speed.

Symptoms to notice

  • Rear end instability or sudden oversteer when cornering at speed, especially under load
  • Rapid and uneven rear tyre wear across the tread width or concentrated on one shoulder
  • Rear of the vehicle feels unsettled or skittish over mid-corner bumps
  • Wheel alignment technician unable to bring rear toe or camber within specification

What to check

  1. Grip each link by hand and attempt to move it axially and radially — any movement beyond 1–2 mm indicates bush failure.
  2. Check the rear wheel alignment toe and camber values against specification; values outside tolerance with no prior impact history indicate bush collapse.
  3. If a workshop inspection is possible: With the vehicle on a hoist at laden ride height (simulate load or use a suspension table), inspect each rear link bush visually for rubber cracking, extrusion from the housing, or visible metal-to-rubber separation.

Where to look: Rear multi-link suspension subframe, trailing arms, and lateral links — both left and right sides

Ask the seller

  • “When was the last wheel alignment performed, and were any out-of-specification angles noted at the rear?”
  • “Does the rear of the vehicle feel loose or unsettled when cornering at highway speed?”
  • “Have any rear suspension bushes or links ever been replaced?”

07Front lower control arm bush deterioration

Inspect the rubber surface of the front pivot bush for radial cracks or splitting.2006 onwardSuspension
Very commonSuspension $350–$1,200 to fix

Can't confirm for this car

The front lower control arm on the Outlander ZH through ZL uses a front-pivot rubber bush pressed into the arm's leading eye and a rear eccentric bush that also forms part of the camber and caster adjustment. The NZ operating environment of frequent gravel roads, salt-air coastal exposure, and heavily potholed urban roads accelerates rubber hydrolysis in both bushes. The rear eccentric bush in particular carries high shear loads under combined braking and cornering forces, and splits along its axis allowing the arm to pivot laterally under load. This produces vague steering response and a clunking noise over road imperfections. The failure is so prevalent in the NZ market that it is considered a routine pre-purchase check item by specialist workshops. Both petrol and PHEV variants are affected equally as the suspension geometry and bush specification are identical.

08Front hub wheel bearing premature failure

Spin the wheel by hand and feel for roughness, resistance, or grinding.petrol2006–2015Suspension
CommonSuspension $450–$1,100 to fix

Can't confirm for this car

The front wheel bearing assembly on ZH and ZJ Outlanders is a sealed double-row angular contact bearing pressed into the front steering knuckle. The bearing specification proved marginal for the Outlander's kerb weight of approximately 1,600-1,700kg, particularly on rough NZ sealed and gravel roads. The bearing inner race is susceptible to fretting corrosion at the hub spline interface, and the lip seals allow moisture ingress on vehicles exposed to wet gravel road spray and stream crossings. Once contaminated, ball raceways pit and the bearing produces a characteristic droning noise that changes pitch during lane changes as the load distribution shifts between the two bearing rows. Delayed replacement leads to heat generation in the knuckle, potential ABS tone ring corrosion, and in severe cases bearing seizure.

Symptoms to notice

  • Droning or humming noise from one front corner that varies with vehicle speed
  • Noise changes pitch or intensity when changing lanes due to load transfer between bearing rows
  • Vibration felt through the steering wheel at certain speed ranges
  • ABS warning light or wheel speed sensor fault codes due to damaged tone ring
  • Roughness or play when rocking the wheel at 12 and 6 o'clock positions on a hoist

What to check

Spin the wheel by hand and feel for roughness, resistance, or grinding. During the test drive, listen for a drone that increases with speed and changes when steering slightly left or right. Scan for any stored wheel speed sensor or ABS fault codes. If a workshop inspection is possible: With the vehicle on a hoist, grasp the tyre at 12 and 6 o'clock and rock firmly - any clunking or movement indicates play in the bearing or lower ball joint.

Where to look: Front wheel hub assembly, inside the front steering knuckle on both left and right sides

09Rear Brake Caliper Piston Seizure

The rear brake calipers on Outlanders are prone to piston seizure, particularly on vehicles that have seen infrequent brake use on the rear axle.2006 onwardBrakes
CommonBrakes $280–$950 to fix

Can't confirm for this car

The rear brake calipers on Outlanders are prone to piston seizure, particularly on vehicles that have seen infrequent brake use on the rear axle. The Outlander's brake bias and the PHEV's regenerative braking system mean the rear calipers often go extended periods without full mechanical actuation, allowing the piston boot seals to harden and the piston to corrode in place. A seized rear caliper causes the affected pad to drag continuously, generating brake fade, uneven wear, and in some cases sufficient heat to damage the wheel bearing and hub.

Symptoms to notice

  • Rear brake disc and hub running noticeably hotter than the front after normal driving, indicating a dragging caliper piston on one or both sides
  • Uneven rear brake pad wear — one side significantly more worn than the other, or rear pads far more worn than front pads

What to check

After a test drive, carefully feel each rear wheel hub and disc for unusual heat compared to the front — a seized caliper will produce significantly more heat on the affected side. Inspect rear brake pad thickness and compare wear between left and right and between front and rear. Pull back the caliper dust boots and look for corrosion at the piston face. Operate the park brake through its full range and check for equal resistance.

Where to look: Rear brake calipers, both sides

Parts involved: Brake disc and pads.

Ask the seller

  • “When were the rear brake calipers last serviced or replaced?”
  • “Have you noticed any pulling or heat from the rear brakes?”
  • “On the PHEV, has the rear mechanical braking ever been tested independently of regenerative braking?”

11Brake Caliper Guide Pin Seizure

The front and rear brake calipers on the CW Outlander use sliding guide pins to allow the caliper body to move laterally as the brake pads wear.2006–2012Brakes
CommonBrakes $180–$550 to fix

Can't confirm for this car

The front and rear brake calipers on the CW Outlander use sliding guide pins to allow the caliper body to move laterally as the brake pads wear. The guide pins are protected by rubber dust boots, which crack and split over time, exposing the pin and its bore to moisture and road contamination. The pins corrode and seize within their bores, preventing the caliper from retracting fully after brake application. This causes the brake pad on the piston side to drag continuously against the rotor, generating significant heat, accelerating pad and rotor wear, and creating brake pull to one side. In severe cases the seized caliper can cause enough heat to fade the brake fluid or crack the rotor disc.

Symptoms to notice

  • Vehicle pulling to one side under braking without any steering input
  • One corner of the vehicle feels warm or hot to the touch after normal driving
  • Rapid and uneven brake pad wear with the inner pad wearing significantly faster than the outer pad on the same axle
  • Brake judder or vibration through the pedal caused by rotor heat distortion from continuous caliper drag

What to check

After a test drive, carefully approach each wheel and check for heat radiating from the wheel — a seized caliper will make one corner noticeably hotter than the others. Inspect the dust boots for cracking, splitting, or absence. Measure remaining pad thickness on both inner and outer pads — a large discrepancy (more than 3 mm) between inner and outer pad thickness on the same caliper confirms uneven wear from a dragging caliper. If a workshop inspection is possible: Remove the caliper and attempt to slide each guide pin in and out of its bore by hand; a seized pin will be immovable or require excessive force.

Where to look: Front and rear brake calipers at all four corners, guide pins located at the top and bottom of each caliper bracket

Parts involved: Brake disc and pads.

Ask the seller

  • “When were the brake pads and rotors last replaced, and was there uneven wear noted at that time?”
  • “Does the vehicle pull to one side when braking?”
  • “Have the brake caliper guide pins ever been cleaned, lubricated, or replaced?”

12Front lower control arm bushing wear causing knocks and squeaks

The front lower control arm (pillow-ball) outer bushings on the 2002-2005 Outlander/Airtrek platform are a well-documented weak point.2001–2006Suspension
CommonSuspension $250–$800 to fix

Can't confirm for this car

The front lower control arm (pillow-ball) outer bushings on the 2002-2005 Outlander/Airtrek platform are a well-documented weak point. A design flaw in the bushing seal lets water enter, corroding and wearing the joint, which produces squeaks, groans and knocking most noticeable over speed bumps and rough roads. Severely worn bushings allow metal-to-metal contact between the arm and bracket. Ball joints, sway-bar links and strut mounts on these older cars should be checked at the same time.

Symptoms to notice

  • Squeak or groan over speed bumps and rough surfaces
  • Knocking or clunking from the front suspension
  • Vague or wandering front-end feel
  • Uneven front tyre wear

What to check

With the front end raised, lever-check each lower control arm bushing and ball joint for play, and inspect the outer bushings for splits or water damage. On the road, listen for squeaks and knocks over bumps and note any looseness in the steering.

Where to look: Front lower control arms, outer bushings

Parts involved: Shock absorber / strut, Ball joint.

Ask the seller

  • “Are there any knocks or squeaks from the front over bumps?”
  • “Have the control arms or bushings been replaced?”
  • “When was the suspension last inspected?”

13Rear Tailgate Gas Strut Failure

Open the tailgate fully and release it — it should hold open without support.2006 onwardBody & Rust
Very commonBody & Rust $80–$250 to fix

Can't confirm for this car

The rear tailgate/hatch on both the CU/CW and GF/GG/ZK/ZL Outlander platforms uses gas-charged struts that progressively lose pressure over 5–8 years. The hatch drops under its own weight and will not hold open, creating a safety hazard for anyone reaching into the cargo area. On the powered tailgate variants (ZK/ZL), failed struts can also overload the electric actuator motor. Replacement is straightforward but the fault is almost universal on vehicles over 8 years old.

Symptoms to notice

  • Tailgate slowly drops when released and will not stay open
  • Hatch slams down when pushed fully open
  • Squeaking or groaning from the hatch hinge area
  • Powered tailgate (ZK/ZL) struggles or stalls mid-travel

What to check

  1. Open the tailgate fully and release it — it should hold open without support.
  2. Check both struts for oil seepage around the piston rod seal.
  3. On powered variants, open and close the tailgate using the button and listen for the motor laboring.

Where to look: Either side of tailgate aperture, struts connect body pillar to inner tailgate

Parts involved: Shock absorber / strut.

Ask the seller

  • “Have the tailgate gas struts been replaced?”
  • “Does the tailgate hold itself open without support?”
Fluid leaks4

01Front Motor Oil Seal Leak — Inverter Contamination Risk

The front electric traction motor in the Outlander PHEV shares a reduction gear assembly that uses transmission fluid for lubrication.hybrid2013 onwardFluid Leaks
OccasionalFluid Leaks $900–$9,500 to fix

Can't confirm for this car

The front electric traction motor in the Outlander PHEV shares a reduction gear assembly that uses transmission fluid for lubrication. The shaft oil seals on this unit deteriorate with age and accumulated heat cycles, allowing gear fluid to migrate toward the high-voltage inverter module mounted directly above and adjacent to the motor. Even a small quantity of fluid contaminating the inverter can cause insulation resistance faults, high-voltage warning lights, and ultimately full inverter failure — one of the most expensive PHEV repairs available. The fault is often subtle early on, presenting as only a faint oily residue or gear oil smell near the front motor. If caught before fluid reaches the inverter, a seal replacement is straightforward; if the inverter is already contaminated the repair bill increases dramatically.

Symptoms to notice

  • Oily film or gear oil smell from the front motor area under the bonnet
  • High voltage system warning light or P3000-range fault codes
  • EV mode unavailable or unexpectedly limited
  • Insulation resistance fault codes logged in the hybrid control unit
  • Visible fluid staining on front motor casing or adjacent wiring harness

What to check

Physically inspect the front electric motor area for any oily residue, discolouration, or gear oil smell — focus on the motor shaft exit points at the reduction gearbox. Request a workshop scan specifically for high-voltage insulation fault codes. Ask for any documented history of motor, inverter, or front drive unit service. Do not purchase any PHEV showing active high-voltage system warning lights without specialist clearance.

Where to look: Front engine bay — front electric motor reduction gearbox output shaft seals and adjacent high-voltage inverter unit

Ask the seller

  • “Has the front electric motor or inverter ever been replaced or repaired?”
  • “Are there any active or stored high-voltage system or insulation fault codes?”
  • “Has any fluid leak or oily residue been noticed near the front of the engine bay?”
  • “Has the vehicle had a pre-purchase inspection that included a high-voltage system check?”

02Front e-motor oil seal leak causing traction control fault

Check the front wheel speed sensor wiring harnesses for any oily contamination.hybrid2021 onwardFluid Leaks
OccasionalFluid Leaks $1,200–$5,500 to fix

Can't confirm for this car

The front electric drive motor (MG2) on the GN Outlander PHEV has a documented tendency for the output shaft oil seal to weep or fail, allowing gear oil from the front reduction gear assembly to migrate along the wiring harness or contaminate the adjacent wheel speed sensor. The resulting erratic or intermittent wheel speed signal causes the stability control and traction control ECU to interpret normal cornering as a wheel slip event, triggering false ABS, traction control, or AWC (All Wheel Control) fault codes. In more advanced cases oil ingress into motor windings causes insulation resistance faults requiring motor replacement. The seal failure is initiated by thermal cycling stress from frequent rapid electric-only acceleration combined with high regenerative braking loads.

Symptoms to notice

  • ABS, traction control, or AWC warning lights illuminated on dry road
  • Traction control falsely activating during normal cornering or acceleration
  • Visible oil seepage or residue around the front electric motor housing or subframe
  • Oil smell from the front underside after spirited driving
  • Wheel speed sensor fault codes stored in ABS or AWC ECU scan data

What to check

  1. Check the front wheel speed sensor wiring harnesses for any oily contamination.
  2. Scan the ABS, AWC, and hybrid ECUs for wheel speed sensor or drivetrain fault codes.
  3. Check the front reduction gear oil level at the drain or fill plug — a low level confirms an active external leak.
  4. If a workshop inspection is possible: Raise the vehicle and inspect the front subframe and electric motor housing underside for oil seepage, residue trails, or fresh wetness.
  5. On the hoist also inspect the inner CV joint boot area and motor output shaft seal face directly.

Where to look: Front electric motor (MG2) output shaft seal and front reduction gear housing, front subframe area

Ask the seller

  • “Have any ABS, AWC, or traction control warning lights appeared?”
  • “Has any oil leak been found under the front of the vehicle?”
  • “Has the front electric motor or front reduction gear had any servicing?”
  • “Are there any stored fault codes in the ABS or AWC control modules?”
