What to look out for
Serious issue
Road test for any shudder; a clean test drive without judder with recently serviced fluid is minimum reassurance.
CVT Belt Abrasion and Catastrophic Pulley Failure
When the CVT hydraulic judder fault (above) is left unaddressed, ongoing belt slippage generates abrasion powder that contaminates the hydraulic pressure circuit and rapidly wears the steel push-belt and pulley contact surfaces. Mitsubishi TSB-20-23-001 explicitly states that continued driving under shudder conditions causes belt slip and abrasion powder contamination leading to CVT warning illumination with codes P0776, P0730, or P084A. The end-stage failure is complete CVT seizure or loss of drive, requiring full transmission replacement.

Serious issue
For any 2011 or 2012 1.8D ASX, verify recall completion via the NZTA recall check tool or the Mitsubishi NZ dealer recall lookup before purchase.
4N13 Diesel Piston Ring Soot Seizure — Safety Recall (2011-2012)
A software defect in the ECU pilot-injection timing allowed soot to accumulate in the piston ring grooves of the 1.8D 4N13 engine, causing the rings to seize in their lands and pistons to overheat. Mitsubishi issued a formal safety recall covering approximately 1,588 diesel ASXs built in 2011 and 2012; the remedy was an ECU reprogram to alter pilot-injection timing and prevent soot accumulation. Vehicles on which the recall was not completed face risk of sudden catastrophic engine stall with no restart capability due to seized pistons overheating and potentially melting.
What you would notice
Serious issue
Start the engine from cold and listen carefully at the timing cover on the front of the engine for any metallic rattling during the first 30 seconds.
4J11 2.0L timing chain guide and tensioner wear
The Mitsubishi 4J11 2.0L MIVEC engine uses a single-row timing chain with a plastic guide rail on the slack side and a hydraulic ratcheting tensioner. The plastic guide material degrades from sustained heat cycling and the oil galleries supplying the tensioner can restrict with sludge when oil changes are delayed beyond 10,000km. As the guide wears, the chain begins to slap against the guide rail on cold starts before oil pressure reaches the tensioner. Over time the guide fractures, debris enters the oil circuit, and the chain can jump a tooth on the intake or exhaust camshaft sprocket. A jumped tooth causes significant timing error leading to rough running and potential valve contact. This failure pattern is strongly correlated with extended oil service intervals and incorrect oil viscosity use.
What you would notice
Costly issue
Inspect rubber surfaces for splits and oil contamination from nearby seals.
Front lower control arm bush wear
The ASX XA through XC front lower control arm uses identical bush specification and subframe mounting geometry to the related Outlander platform. The front pivot rubber bush and rear eccentric alignment bush are subject to the same rubber hydrolysis and shear failure mechanism under NZ road conditions. The ASX's lighter kerb weight reduces absolute load magnitude on the bushes but the same rubber compound and design is used, resulting in comparable fleet failure rates. Bush wear typically manifests after 80,000-120,000km in normal NZ conditions with gravel road exposure advancing the timeline. Many NZ-registered ASX vehicles fail their WoF inspection on this item, and replacement is considered routine maintenance rather than an exceptional repair in the specialist workshop sector.
What you would notice
Costly issue
Test drive at 20–40 km/h with light throttle on a gentle uphill; feel for a rhythmic shudder or hesitation.
CVT INVECS-III Low-Speed Judder and Surge
The INVECS-III CVT fitted across the ASX petrol range is prone to a pronounced shudder or surge during light acceleration at 20–40 km/h, caused by sluggish hydraulic pressure circuit reaction in the belt secondary pulley circuit. Mitsubishi issued TSB-17-23-002 in April 2017, superseded by TSB-20-23-001 in April 2020, and revised again as TSB-22-23-001REV in February 2022, confirming this fault is persistent and widespread. Fluid degradation from missed service intervals accelerates onset, and the condition can set DTCs P0776, P0730, or P0741.
What you would notice
Costly issue
Check the oil level on the dipstick — a reading above maximum with no obvious external leak is a strong indicator of fuel dilution.
4N13 1.8D DPF Oil Dilution from Incomplete Regeneration
The 1.8-litre 4N13 diesel uses post-injection fuel pulses during active DPF regeneration; on vehicles used predominantly for short urban trips the regeneration cycle is repeatedly interrupted before completion, causing unburned diesel to wash down the cylinder bores and accumulate in the engine oil sump. The oil level rises above the maximum dipstick mark, triggering an oil level warning, and the diluted oil loses its lubricating properties. This mechanism is extensively documented on Mitsubishi owner forums and a Denso 4N13 DPF fault thread on MHH Auto, and in severe cases leads to premature bearing and bore wear.

Can't confirm for this car
Can't confirm for this car
The 4B11 2.0L engine in the ASX shares the same piston ring seal vulnerability as the Outlander unit. At higher mileages (typically above 100,000 km), oil consumption above 1 litre per 5,000 km is reported without external leaks. The issue is worsened if extended drain intervals are used. Unchecked, oil starvation can accelerate timing chain tensioner wear, given the chain relies on oil pressure for tensioner function. Buyers of high-mileage ASX examples should treat oil consumption as a likely expense.

Can't confirm for this car
The 2.0-litre 4B11 petrol engine uses a hydraulic timing chain tensioner that loses prime after extended oil-change intervals or at high mileage, allowing chain slack to develop on cold start. A persistent rattle from the front of the engine in the first few seconds after a cold start is the primary indicator; if ignored, the chain stretches sufficiently to cause timing correlation errors (P0016, P0017) and can jump a tooth on the crankshaft or camshaft sprocket, risking piston-to-valve contact and catastrophic engine damage. This failure pattern is documented across EvolutionM forums and multiple engine-specific guides for the 4B11 platform.

09Rear AWD Electromagnetic Coupling Wear and Cornering Shudder
Can't confirm for this car
Can't confirm for this car
AWD variants of the ASX use an electronically-controlled rear multi-plate coupling to transfer torque to the rear axle on demand; the coupling fluid degrades over time and the friction plates wear, producing a pronounced shudder or tramping sensation during slow-speed tight turns such as in car parks or during three-point turns. The condition is frequently misdiagnosed as CVT judder or wheel bearing noise. Early-stage shudder often responds to a genuine Mitsubishi rear coupling fluid drain and refill; advanced friction plate wear or coupling seal failure requires unit replacement.

Can't confirm for this car
The ASX air conditioning system uses a belt-driven compressor with an electromagnetic clutch that engages and disengages the compressor pulley from the drive belt. The clutch armature plate and electromagnetic coil are subject to wear and thermal degradation, particularly in vehicles operated in hot climates such as northern New Zealand and Australia. Clutch slip generates significant heat that destroys the armature contact surface and can seize the clutch hub. A seized or failed clutch can also cause drive belt failure if the compressor locks up.

01Takata airbag inflator recall - must be verified completed
Can't confirm for this car
Can't confirm for this car
The ASX was caught in the compulsory Takata airbag recall in Australia and the equivalent NZ campaign: degraded inflator propellant can rupture the metal housing on deployment and spray shrapnel at occupants. Fixes are free at any Mitsubishi dealer, but imports and cars with lapsed ownership records sometimes slipped through. This is one of the few faults that can kill you in an otherwise healthy car, so a VIN check is non-negotiable on 2010-2017 ASXs.

02Electric Power Steering Motor or Control Unit Failure

Can't confirm for this car
The ASX uses a column-mounted electric power steering (EPS) system with an electric assist motor and a dedicated EPS electronic control unit. The EPS control unit is susceptible to internal solder joint failure and MOSFET degradation from thermal cycling, particularly in vehicles driven in stop-start urban environments. Motor brush wear and winding failure have also been documented on higher-mileage units. Failure results in loss of power assist, which is immediately detectable but requires significant force to steer at low speeds.

03Electronic Throttle Body Carbon Fouling and TPS Range Fault
Can't confirm for this car
Can't confirm for this car
The drive-by-wire throttle bodies fitted to 4B10, 4B11, and 4B12 petrol engines accumulate carbon deposits on the throttle plate and bore over time, progressively disrupting the throttle position sensor (TPS) reference voltage and triggering P0121, P0122, or P0123 fault codes. The ECM detects TPS values outside the expected operating range and may invoke a torque reduction or limp-home response. A throttle body adaptation or re-learn procedure via scan tool is mandatory after cleaning or replacement, as the ECM must relearn the fully-closed and fully-open voltage references.

Can't confirm for this car
On 2013 to 2015.5 model year ASXs, inadequate sealing of the integrated rear parking brake caliper allows water ingress that corrodes the parking brake actuator shaft, preventing the parking brake from fully engaging. Mitsubishi issued a formal safety recall in February 2018 covering vehicles built between August 2012 and May 2016; unrepaired examples risk rollaway incidents when parked on any incline. Buyers should verify recall completion through the NZTA safety recall register or a Mitsubishi dealer check before purchase.

02Rear Trailing Arm Bush Collapse
Can't confirm for this car
Can't confirm for this car
The rear multi-link suspension on the ASX uses rubber-bonded trailing arm bushes that locate the rear axle fore-aft under acceleration and braking loads. These bushes degrade and collapse after sustained use, particularly in vehicles driven on unsealed roads or subjected to frequent hard braking. Bush failure causes the rear axle to move fore-aft under load, producing handling instability and accelerating rear tyre wear in an asymmetric pattern. The failure is progressive but eventually compromises vehicle stability under emergency braking.

03Hydraulic Power Steering Pump Seal Leak and Whine
Can't confirm for this car
Can't confirm for this car
Early ASX variants (pre-facelift and some 2013-2016 models) fitted with a hydraulic power steering (HPS) rack use a belt-driven vane-type pump that develops shaft seal leaks and bearing whine with age. The high-pressure hose banjo fittings are also a known leak point. Loss of fluid causes the pump to whine loudly at full lock and progressively increases steering effort. Running the pump low on fluid accelerates internal wear of the rotor and vanes, ultimately requiring full pump replacement. Some markets saw a mid-cycle transition to electric power steering (EPS), but earlier hydraulic-equipped cars remain in the NZ used-car fleet.

Can't confirm for this car
The front lower control arm ball joint on the ASX is a press-fit unit integrated into the lower arm assembly. The rubber boot seal is susceptible to cracking in NZ and AU conditions, allowing moisture and grit ingress that accelerates spherical wear in the joint. Once the boot fails, deterioration is rapid. Worn ball joints create a handling safety risk as the joint can separate under load, causing sudden loss of front wheel geometry control.

06Rear Torsion Beam Axle Bush Deterioration
Can't confirm for this car
Can't confirm for this car
The ASX uses a torsion beam (twist-beam) rear axle suspended by large rubber bushes at each mounting point to the body. These bushes are subject to age-hardening, ozone cracking, and splitting — particularly on vehicles exceeding 100,000 km or aged beyond ten years. Deteriorated bushes allow the axle to shift under lateral load, causing unpredictable rear-end handling and tyre scrub. In severe cases the metal sleeve can separate from the rubber, allowing the axle to contact the body. The condition is often missed at casual inspection because the bushes are partially hidden by the body structure. NZ/AU roads and UV exposure accelerate rubber degradation.

07Brake Caliper Guide Pin Seizure
Can't confirm for this car
Can't confirm for this car
The front and rear brake calipers on the ASX use sliding guide pins that allow the caliper body to float and apply equal pressure to both brake pads as the disc is clamped. These guide pins are lubricated with high-temperature grease and protected by rubber boots, but the boots deteriorate over time, allowing moisture to displace the grease and cause the steel pin to corrode within its aluminium caliper bore. A seized guide pin causes the caliper to apply uneven clamping force, resulting in one brake pad wearing significantly faster than the other and generating braking bias.

08Rear Brake Caliper Piston Seizure
Can't confirm for this car
Can't confirm for this car
The rear sliding-pin calipers on the ASX are prone to piston seizure in New Zealand and Australian conditions due to moisture intrusion past degraded piston dust seals and corrosion of the piston bore. A seized piston either fails to retract after braking (causing constant pad drag and rapid lining wear) or fails to advance fully (causing one-sided braking). The sliding pins in the caliper bracket are also susceptible to corrosion, reducing the caliper's ability to self-centre. Vehicles used in coastal or high-rainfall environments are disproportionately affected. The condition can progress unnoticed until a WoF inspection or until the rear rotor overheats and warps.

Can't confirm for this car
ASXs are known for chewing through front lower control arm bushes and ball joints, which shows up as clunks over bumps, vague steering, uneven front tyre wear and failed WOF checks in NZ. The rear hydraulic bush in each front arm is the usual culprit; many workshops fit complete aftermarket arms because pressing bushes costs nearly as much. It's a wear item, but on the ASX it arrives earlier than most rivals and is one of the most common WOF failure points for the model.

The ASX tailgate uses gas-pressurised struts that reliably fail after 6–9 years of use. The hatch will no longer hold its open position and drops, posing an injury risk. This is the most frequently reported minor defect on used ASX examples sold at auction and private sale in NZ and AU. Struts are inexpensive aftermarket items but should be confirmed replaced before purchase to avoid immediate out-of-pocket cost.
