What to look out for

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

  • Costly issue

    Inspect the rear inboard bush for cracking, splitting, or offset movement of the inner sleeve.

    See why

    Front lower arm rear bush failure - highway speed shimmy

    The GT-generation XV front lower control arm uses a compliance bush at the rear inboard pivot that is calibrated for ride comfort but degrades relatively early, typically from 60,000-90,000 km. As the rubber matrix breaks down, lateral and longitudinal compliance increases beyond tolerance, allowing the front wheel to toe-out slightly under cornering and braking load. The primary symptom is a steering shimmy or wobble felt through the wheel at 90-120 km/h, particularly pronounced over minor road undulations. The condition worsens progressively. Because the bush is integrated into the pressed-in lower arm assembly on most variants, Subaru dealers typically replace the complete arm rather than re-bushing. Aftermarket polyurethane bush kits are available and are a cost-effective alternative when installed with correct torque.

    What you would notice

    • Steering wheel shimmy or oscillation at 90-120 km/h
    • Vibration felt through steering wheel over highway undulations
    • Wandering or imprecise steering feel
    • Uneven or feathered tyre wear on front inner edge
    • Toe-out visible on wheel alignment printout

    Typically $450–$1,100 to put right.

  • Costly issue

    Check for pulling under braking.

    See why

    Brake Caliper Guide Pin Seizure

    Front brake caliper guide pins seize from corrosion causing uneven pad wear.

    What you would notice

    • Vehicle pulling to one side under braking
    • One front disc hotter than the other after moderate use

    Typically $150–$500 to put right.

  • Common issue

    Inspect rear suspension arm bushes for cracking and deformation.

    See why

    Rear Suspension Multi-Link Bush Collapse

    Rear multi-link suspension arm bushes harden and collapse causing rear knocking and handling imprecision.

    What you would notice

    • Knocking from rear suspension over rough surfaces and speed humps
    • Imprecise rear handling feel and slight inner rear tyre edge wear

    Typically $400–$1,200 to put right.

A 2024 Subaru XV: what is due, and when

Servicing

Next service

60,000 km

The first major service, at which inspecting the CVT fluid and looking at the spark plugs is standard practice.

In about 40,000 km, on this estimate.

Placed by the car’s age, not read from the dash — 13,800–32,200 km after 2 years.

Timing

Our research does not record which this engine uses, and it depends on the engine rather than the model. Check the owner’s manual rather than assume: on a belt-driven engine, an overdue belt is the failure that takes the engine with it.

Ahead of it

  • 100,000 kmA thorough check of the suspension parts and cooling system hoses, and the accessory drive belt may need replacing.
  • 150,000 kmWorth getting ahead of the cooling system parts and suspension dampers here to keep that signature Subaru ride quality.

“Behind it” means the car has driven past that distance, not that the work was done — ask to see the receipts. These are the intervals for the Third Generation (GU) - Rebranded as Crosstrek · 2.0L (FB20) - 2.0i / 2.0i-S · Petrol; only the car’s own service book says what has actually been done to it.

01EE20 Diesel DPF Blockage from Urban Use

Check for a DPF warning light on the instrument cluster.diesel2012 onwardEngine
Very commonEngine $500–$3,000 to fix

Can't confirm for this car

The EE20 2.0 SkyActiv-D diesel XV Diesel Particulate Filter blocks up on vehicles used primarily for short urban trips where exhaust temperatures never sustain the level needed for passive DPF regeneration. A blocked DPF illuminates the DPF warning and eventually causes limp mode.

Symptoms to notice

  • DPF warning light on the instrument cluster
  • Power reduction or limp mode as DPF blockage reaches a critical threshold

What to check

  1. Check for a DPF warning light on the instrument cluster.
  2. Scan for P2002 DPF differential pressure codes.
  3. Ask about the owner's typical driving pattern — predominantly short urban trips under 30 minutes are the risk factor.

Where to look: DPF assembly in the exhaust system, underneath the vehicle

02e-Boxer Integrated Motor Bearing Noise and Whine

hybrid2020–2023Engine
OccasionalEngine $3,500–$8,000 to fix

Does not apply

The e-Boxer variant of the XV (sold in NZ/AU from 2020) integrates a 12.3 kW electric motor directly inside the Lineartronic CVT housing on the front axle. A documented failure mode identified in Japanese domestic market TSBs and confirmed in Australian owner forums involves bearing wear inside the integrated motor unit producing a distinct high-frequency whine or drone under electric-only crawl, regenerative braking, or during the transition between electric and combustion drive at low speed. The motor/generator assembly is not field-serviceable separately and typically requires CVT-motor assembly replacement.

Symptoms to notice

  • High-pitched whine or drone audible at low speed during electric-only operation, changing pitch with road speed
  • Tonal noise during regenerative braking deceleration below 40 km/h
  • Vibration or resonance felt through the floor during EV-mode transitions
  • Hybrid system warning light or 'Hybrid System Fault' message in advanced cases
  • Noise absent at higher speeds when combustion engine masks it, making it easy to miss on a fast test drive

What to check

With the vehicle in EV crawl mode (below 40 km/h on a flat surface), listen for a high-pitched whine or drone that changes pitch with vehicle speed rather than engine speed. Engage regenerative braking by lifting off the throttle at low speed and listen for the same tonal noise through the firewall. The noise is distinct from normal CVT belt hiss and is continuous rather than intermittent. Check for any hybrid system warning lights and ask if the dealer has ever inspected the integrated motor.

Where to look: Integrated motor-generator unit inside the Lineartronic CVT housing, forward of the firewall

Ask the seller

  • “Has the hybrid motor or CVT-motor assembly ever been inspected or replaced under warranty?”
  • “Is there any whine or drone noise audible when creeping in EV mode in a car park?”
  • “Has the vehicle ever shown any hybrid system warning lights, even briefly?”

06FB20D Intake Valve Carbon Buildup — Direct Injection Fouling

On a high-mileage example (above 80,000 km), ask whether intake valve cleaning has ever been performed.petrol2017–2023Engine
CommonEngine $650–$1,600 to fix

Does not apply

The FB20D engine uses Subaru's direct injection system (fuel sprays directly into the cylinder, bypassing the intake valves). Unlike port-injected engines where fuel flow washes the intake valves clean, direct injection means oil vapour from the PCV system coats the intake valve stems and heads with carbon deposits over time. This is a documented and inherent characteristic of all GDI engines. On the FB20D, significant buildup typically manifests between 60,000 and 120,000 km and causes rough idle, misfires, and reduced throttle response. The only effective remediation is mechanical walnut blasting or chemical cleaning of the intake ports with the inlet manifold removed.

Symptoms to notice

  • Rough idle or misfires on cold start that clear as the engine warms up
  • Hesitation or stumble during light throttle acceleration, particularly below 3,000 rpm
  • Reduced fuel economy noted progressively over high mileage
  • OBD misfire codes (P030X) with no ignition or fuel injector faults present
  • Visible carbon coke deposits on valve stems and heads when inspected via borescope

What to check

On a high-mileage example (above 80,000 km), ask whether intake valve cleaning has ever been performed. During the test drive, note any hesitation, rough idle, or stumble on cold start that smooths out once warm — a classic carbon deposit symptom. Check whether the air-oil separator or PCV system has ever been serviced. If a workshop inspection is possible: A borescope inspection of the intake port through the inlet manifold will reveal visible carbon coating on valve heads.

Where to look: Intake valves and ports on both cylinder banks of the FB20D engine, accessed by removing the intake manifold

Parts involved: Intake manifold, PCV / oil separator.

Ask the seller

  • “Has the intake manifold ever been removed for valve cleaning or carbon walnut blasting?”
  • “Has the vehicle experienced any misfire codes or rough idle that was investigated?”
  • “What is the current odometer reading, and has the PCV system or air-oil separator ever been replaced?”

01e-Boxer 12V Auxiliary Battery Drain and Hybrid System Non-Start

Ask whether the vehicle has ever failed to start or shown a 'Hybrid System Unavailable' message.hybrid2020–2023Electrical
OccasionalElectrical $280–$900 to fix

Does not apply

The e-Boxer hybrid system in the XV uses a conventional 12V AGM auxiliary battery to initialise the high-voltage hybrid system before the main traction battery can supply power. This 12V battery is smaller than a conventional vehicle's starter battery and is documented to drain rapidly if the vehicle sits unused for more than a few days, or if there is any parasitic draw from the hybrid control modules or infotainment system in sleep mode. A drained 12V battery prevents the hybrid system from powering up entirely, leaving the vehicle unable to start even though the high-voltage traction battery may be fully charged. Subaru issued guidance on this pattern and the 12V battery is considered a higher-wear component on the e-Boxer.

Symptoms to notice

  • Vehicle fails to start with 'Hybrid System Malfunction' or 'Power System Fault' warning after sitting unused
  • Infotainment and instrument cluster powering up but engine and hybrid drive refusing to engage
  • Repeated need to jump-start or recharge the 12V battery
  • Multiple hybrid warning lights appearing simultaneously, clearing once 12V is recharged
  • Battery drain occurring faster than on a conventional vehicle when parked for several days

What to check

  1. Ask whether the vehicle has ever failed to start or shown a 'Hybrid System Unavailable' message.
  2. Check for parasitic draw by asking if the vehicle has sat unused for a week and started normally afterward.
  3. Inspect the battery terminals for corrosion.
  4. Check the age of the 12V battery against the service record — replacement interval in hybrid use is typically 3-4 years.
  5. If a workshop inspection is possible: Test the 12V auxiliary battery voltage with a multimeter or conductance tester — it should read 12.6V or above at rest.

Where to look: 12V AGM auxiliary battery, located in the engine bay or under the boot floor depending on build variant

Parts involved: 12V battery.

Ask the seller

  • “Has the vehicle ever failed to start or shown hybrid system warning lights after sitting for several days?”
  • “When was the 12V auxiliary battery last tested or replaced?”
  • “Has any dealer performed a parasitic drain test on the hybrid electrical system?”

01Front Lower Control Arm Ball Joint Wear

Inspect the rubber boot on each ball joint for cracking, splitting, or grease contamination on the surrounding components.2012–2017Suspension
CommonSuspension $350–$900 to fix

Does not apply

The front suspension of the GP XV uses a MacPherson strut arrangement with a pressed-in or bolt-on ball joint at the lower control arm. These ball joints are subject to high vertical and lateral loads, particularly on the rough or unsealed roads common in New Zealand, and the grease seals can fail prematurely, allowing lubricant to escape and contamination to enter. A worn ball joint allows the front wheel to have excessive angular play relative to the arm, degrading steering precision and tyre wear, and in severe cases the joint can separate, causing sudden loss of vehicle control.

Elfix · CC0 · Wikimedia Commons

Symptoms to notice

  • Clunking or knocking noise from the front suspension when traversing bumps, speed humps, or rough surfaces
  • Vague or imprecise steering with the vehicle wandering on straight roads
  • Uneven or accelerated tyre wear on the inner or outer edges of the front tyres
  • Grease visible on the lower control arm or hub knuckle area adjacent to the ball joint boot

What to check

Inspect the rubber boot on each ball joint for cracking, splitting, or grease contamination on the surrounding components. A worn joint will exhibit a knocking noise over bumps that a new joint eliminates. Any play exceeding manufacturer specification (typically nil perceptible play) requires replacement before the vehicle is used. If a workshop inspection is possible: With the vehicle safely raised on a hoist, grasp each front wheel at the 6 o'clock and 12 o'clock positions and attempt to rock it vertically — any detectable play indicates ball joint wear.

Where to look: Lower control arm on each front corner, at the pivot point where the arm connects to the front wheel hub/knuckle assembly

Parts involved: Ball joint.

Ask the seller

  • “When were the front lower ball joints last inspected or replaced, and does the vehicle have a current Warrant of Fitness?”
  • “Has the car been used regularly on unsealed gravel roads or off-road conditions?”
  • “Has there been any knocking or clunking noise from the front suspension?”

02Electric power steering rack rattle on cold start

In cold conditions, start engine and slowly turn the steering wheel lock-to-lock while stationary — listen and feel for clunks or catches.petrol2017–2023Suspension
OccasionalSuspension $900–$3,200 to fix

Does not apply

The GT-generation XV (2017–2023) uses an electric power steering rack that has a documented rattle or knock noise on cold start and when driving over sharp bumps at low temperatures. The rack mounting bushes and internal steering rack components produce noise before the EPS system reaches operating temperature. In some cases the noise is structural — the steering column universal joint develops play. This is distinct from NVH and represents a documented mechanical fault with the EPS rack assembly and associated mountings.

Symptoms to notice

  • Clunking or rattling from steering rack area on cold start when turning wheel
  • Knock or thud over sharp bumps in cold weather that disappears when warm
  • Slight free-play or notchiness in steering at low speeds when cold
  • EPS warning light in some cases

What to check

In cold conditions, start engine and slowly turn the steering wheel lock-to-lock while stationary — listen and feel for clunks or catches. Drive over a sharp road imperfection and feel for steering rack movement. Have the steering column universal joint checked for play by a technician.

Where to look: Electric power steering rack mounted on front subframe; steering column universal joint below dashboard

Parts involved: Steering rack.

Ask the seller

  • “Any clunking from the steering when cold or over sharp bumps?”
  • “Has the EPS warning light ever appeared?”
  • “Has the steering rack or column joint been inspected?”

04Rear Brake Caliper Guide Pin Seizure

2012–2017Brakes
CommonBrakes $180–$650 to fix

Does not apply

The rear brake calipers on the GP XV use a sliding caliper design where the caliper body floats on two steel guide pins coated with a lubricating grease, allowing the caliper to centre itself over the brake rotor as the pads wear. The guide pins are enclosed in rubber boots that deteriorate with age and road exposure, allowing moisture and road salt to displace the grease and initiate corrosion on the pin surface. A seized guide pin prevents the caliper from retracting fully after brake application, causing the inboard or outboard pad to remain in constant contact with the rotor. This results in accelerated and uneven pad wear, excessive rotor heat and warping, and reduced fuel economy from the parasitic drag.

Symptoms to notice

  • One rear wheel becomes noticeably hotter than the other after normal driving, detectable by holding a hand near the wheel without touching it
  • Accelerated or uneven rear brake pad wear, with the inner pad worn significantly more than the outer or vice versa
  • Pulling or deviation to one side under light braking with the handbrake applied evenly
  • A scraping or grinding noise from one rear corner that is present even when not applying the footbrake, indicating constant pad contact with the rotor

What to check

After a drive, carefully approach each rear wheel and feel for excessive heat radiating from the wheel and hub area — a seized caliper will make the disc and hub significantly hotter than the other side. Any stiffness, binding, or inability to slide indicates a seized pin. Compare inner and outer pad thickness — a significant difference confirms the caliper is not releasing evenly. If a workshop inspection is possible: Remove each guide pin and inspect for corrosion, pitting, or damaged rubber boots. With the vehicle cool and on a hoist, remove the rear caliper bolts and attempt to slide the caliper body on the guide pins by hand — it should move freely with light finger pressure.

Where to look: Rear brake calipers mounted on the rear axle knuckle at each rear corner, with guide pins running horizontally through the caliper bracket

Parts involved: Brake disc and pads.

Ask the seller

  • “When were the rear brake pads last replaced, and were the caliper guide pins cleaned, inspected, and regreased at the same time?”
  • “Has the vehicle ever pulled to one side under braking, or has one rear wheel been noticeably hotter than the other?”
  • “Does the vehicle have a current Warrant of Fitness, and were there any brake-related advisories on the most recent inspection?”

05Electric Power Steering Rack Internal Rattle

Any visible lateral movement of the rack relative to the subframe mounts indicates excessive yoke wear or inner tie rod play.2013–2017Suspension
OccasionalSuspension $150–$2,200 to fix

Does not apply

The GP XV is equipped with a column-assist electric power steering (EPS) system that drives a conventional rack-and-pinion gear through an electric motor and torque sensor. The rack-and-pinion gear itself uses a spring-loaded yoke to maintain contact between the pinion gear and the rack, and the yoke preload can diminish with wear, allowing the rack to develop a small amount of lateral free-play. This manifests as a rattle or knock transmitted directly through the steering column and wheel, typically over small bumps and road texture, as the rack moves slightly against the yoke. In addition, the inner tie rod ball joints at each end of the rack can develop play, producing a similar symptom.

Symptoms to notice

  • Rattling or knocking sensation felt through the steering wheel over road texture, cat's-eyes, or rough seal chip surfaces
  • The rattle is reduced or eliminated when slight steering pressure is applied to the wheel
  • Knocking from the steering column area when driving over speed humps or sharp bumps at low speed
  • Vague steering feel on-centre with a small amount of free-play before the steering begins to respond

What to check

Any visible lateral movement of the rack relative to the subframe mounts indicates excessive yoke wear or inner tie rod play. Check both inner tie rod ends by grasping each tie rod and attempting to move it laterally and axially — any play beyond a faint amount indicates a worn inner joint. A rattle confined to the steering wheel and column area that disappears when a light load is applied to the wheel is characteristic of yoke preload loss. If a workshop inspection is possible: With the vehicle on a hoist and the steering in the straight-ahead position, have an assistant shake the steering wheel briskly back and forth through a small angle while you observe the rack for movement.

Where to look: Steering rack mounted transversely across the engine bay subframe, connected to the steering column above and tie rods outboard at each end

Parts involved: Steering rack.

Ask the seller

  • “Has there been any rattling or knocking through the steering wheel, particularly over rough roads or speed humps?”
  • “Has any steering rack, yoke, or tie rod work been done on the vehicle?”
  • “Does the steering feel precise and connected, or is there any vagueness or free-play at the straight-ahead position?”
Fluid leaks2

01FB20 head gasket external oil seep at cylinder deck

Check the exhaust manifold heat shield surface and the area around cylinder 2-3 for baked-on oil.petrol2011–2017Fluid Leaks
OccasionalFluid Leaks $1,300–$2,600 to fix

Does not apply

The first-generation GP-series XV with the FB20 engine exhibits an external oil seep originating at the head gasket-to-block interface on the exhaust side of the cylinder head, typically between cylinders 2 and 3. Unlike the catastrophic internal coolant-combustion breach seen on the older EJ-series engines, the FB20 failure is predominantly an external oil weep that tracks down the side of the block and accumulates on the exhaust manifold heat shield and underbody. It does not usually cause coolant loss or overheating unless left untreated for an extended period. The seep is accelerated by cooling system pressure cycling and is more prevalent on higher-mileage examples that have not had the cooling system flushed at recommended intervals. Repair requires cylinder head removal, resurfacing, and new multi-layer steel head gasket installation.

Symptoms to notice

  • Oil residue on exhaust side of engine block below cylinder head
  • Burning oil smell from engine bay after driving
  • Oil accumulation on exhaust heat shields
  • Gradual oil consumption without visible drips beneath car
  • Faint blue smoke from exhaust when oil contacts hot manifold

What to check

  1. Check the exhaust manifold heat shield surface and the area around cylinder 2-3 for baked-on oil.
  2. Compare oil level at purchase against a week later after normal driving to quantify consumption rate.
  3. If a workshop inspection is possible: Inspect the exhaust side of the cylinder block at the head gasket joint line for oil tracking or residue, best viewed from below on a hoist.

Where to look: Cylinder head gasket joint, exhaust side of FB20 engine block, primarily cylinders 2-3

Parts involved: Head gasket.

Ask the seller

  • “Has the head gasket been replaced or has any oil seep from the cylinder head been noted?”
  • “Has the cooling system been flushed at the recommended 100,000 km interval?”
  • “Is the oil level stable between services or does it require topping up?”
  • “Any history of overheating or high coolant temperature warnings?”

02Rear Differential Rear Output Shaft Seal Oil Leak

Check the rear brake pads and disc surfaces for contamination (oily sheen or discolouration).2012–2017Fluid Leaks
OccasionalFluid Leaks $250–$800 to fix

Does not apply

The GP XV uses Subaru's symmetrical all-wheel-drive system with a rear differential integrated into the rear final drive unit. The output shaft seals on each side of the rear differential are subject to heat cycling, contamination, and age-related hardening that causes them to lose their sealing ability, allowing gear oil to weep past the lip seal and onto the brake components or driveshaft. Contaminated rear brake pads and discs are a direct safety consequence, as differential oil on friction material severely reduces braking effectiveness. Early detection allows relatively inexpensive seal replacement, but delayed repair leads to gear oil starvation in the differential and subsequent bearing or gear damage.

Symptoms to notice

  • Oily residue or a wet stain on the rear differential casing, inner face of the rear wheel, or driveshaft adjacent to the differential flange
  • Reduced rear braking effectiveness or a pulling sensation to one side under braking caused by oil-contaminated pads
  • A burnt oil smell from the rear of the vehicle after extended driving as oil contacts the hot exhaust or brake components
  • Low differential oil level confirmed when the filler plug is removed during service

What to check

Check the rear brake pads and disc surfaces for contamination (oily sheen or discolouration). Check the differential fluid level if a filler plug is accessible. Any wet seal requires replacement before continued use, and any oil-contaminated brake pads must be replaced simultaneously. If a workshop inspection is possible: With the vehicle on a hoist, inspect both sides of the rear differential output shaft flanges for any oily residue or wet staining on the casing, driveshaft, or inner face of the rear brake assembly.

Where to look: Rear final drive/differential unit mounted under the rear of the vehicle, at the output shaft flanges where the rear driveshafts exit each side of the differential casing

Parts involved: Differential.

Ask the seller

  • “Has the rear differential ever leaked oil or had the output shaft seals replaced?”
  • “When were the rear brake pads last replaced, and were they replaced due to oil contamination?”
  • “When was the rear differential fluid last checked or changed?”
