What to look out for
Common issue
Inspect high-pressure hose full length including crimped ends for weeping or staining.
Power Steering Hose and Rack Seal Leaks
Standard Lancers with hydraulic power steering develop leaks at the high-pressure hose crimped ends and at the rack pinion seals. The high-pressure hose is routed close to the exhaust and heat causes the rubber to harden and crack at the metal crimp fittings. Rack seals also deteriorate with age, producing slow weeps that contaminate the subframe and inner CV boots. Power steering fluid loss causes increasing steering effort and can lead to pump damage if ignored.

014G63T Spun Rod Bearings at High Mileage or After Modification (Evo VII–IX)
Can't confirm for this car
Can't confirm for this car
The 4G63 turbocharged engine in Evo VII, VIII, and IX variants is susceptible to spun big-end rod bearings when operated at high oil temperatures without adequate maintenance, or when power is increased beyond stock levels. The bearings spin in the connecting rod bore, scoring the crankshaft journal and destroying the rod. Contributing factors include extended oil change intervals, use of non-OEM specification oil, oil starvation during hard cornering when the oil level is low, and high-boost aftermarket tuning. Many NZ Evo examples are modified and have unknown service histories from JDM import. Early signs include a low rumbling knock at idle or on deceleration.

Can't confirm for this car
Can't confirm for this car
The 4G18 1.8-litre engine fitted to standard Lancer models uses a timing belt that is prone to accelerated stretch when the water pump bearing begins to fail. The water pump is belt-driven and its bearing failure increases belt load and causes misalignment, which can cause the belt to skip teeth or break, resulting in catastrophic valve-to-piston contact. Many NZ examples arrive with no documented belt history. Recommended replacement interval is 90,000 km or 5 years, but failed water pump bearings can cause belt failure well before this. The belt tensioner pulley bearing is also a known weak point.

Can't confirm for this car
The Invecs-III Jet-CVT fitted to standard Lancer models develops a shudder or vibration felt through the drivetrain under light throttle acceleration, particularly between 30–80 km/h. Caused by torque converter lock-up clutch slip and deteriorated CVT fluid losing its friction-modifier properties. Can escalate to full CVT slipping and overheating if fluid is not changed at the correct interval. Mitsubishi issued revised fluid specifications and reduced service intervals to address this. Full CVT replacement is required if the unit is allowed to run dry or overheat.

Every CH Lancer sedan and wagon built from 11 June 2003 to 30 December 2008 and every CT9A Lancer Evolution VIII and IX (all engines) was recalled in Australia (PRA 2015/14936) because the Takata front passenger airbag inflator can rupture when it fires and throw metal fragments at the occupants. Some cars were first fixed with like for like Takata parts and were recalled again under PRA 2018/16731. The dealer fix is free. Japanese import Evolutions should be checked by chassis number, as the Japanese campaign ran separately.

Can't confirm for this car02Front Upper Control Arm Ball Joint Wear (Evo VII–IX)
Can't confirm for this car
Can't confirm for this car
The front upper control arm ball joints on Evo VII–IX wear prematurely under the combination of high lateral cornering forces and the high-caster suspension geometry. Worn upper ball joints produce vague steering, increased positive camber on the affected side, and knocking over bumps. Failure of the ball joint is a critical safety risk as the joint can separate under load, causing sudden loss of steering. Aftermarket pillow ball replacements are available and are commonly used in performance applications but require more frequent inspection.
Example of the part — not this vehicleA separated lower ball joint: the control arm has dropped and the wheel has splayed out under the guard.

014G63T 2.0 turbo crank walk — thrust bearing failure (Evolution I–IV)
Does not apply
Does not apply
The 2.0 turbo 4G63 fitted to the Evolution I through IV uses a thrust bearing arrangement Mitsubishi themselves later revised, and the crankshaft can begin to move fore and aft in the block — known universally as crank walk. Mitsubishi changed the arrangement for the Evolution V onward and the failure essentially disappears from those engines, which makes this a defined problem of the early cars. Once it starts it destroys the block, so it is an engine-out rebuild or a replacement engine rather than a repair. Endplay should be around 0.1 mm and no more than 0.25 mm. Because these are all Japanese imports in New Zealand, service history is usually thin and the clutch-related symptoms are the practical warning.

024B11T Timing Chain Tensioner Wear at High Mileage (Evo X)
Does not apply
Does not apply
Unlike the belt-driven 4G63, the 4B11T uses a timing chain. The chain tensioner and guide rails are subject to wear at high mileage, particularly on vehicles that have had infrequent oil changes or that have been used on track. A worn tensioner causes the chain to develop slack, producing a rattling noise on cold start that may clear once oil pressure builds. If chain slack is not addressed, the chain can jump a tooth or fail entirely, causing catastrophic valve and piston damage. This failure becomes more prevalent above 150,000 km.
Example of the part — not this vehicleThe front of a twin-cam engine with the timing cover off — chain, sprockets and guides.

034B11 Oil Pump Drive Gear Wear
Does not apply
Does not apply
The 4B11 2.0L engine uses a chain-driven oil pump whose drive gear teeth wear prematurely, particularly on vehicles with infrequent oil changes or those that have been run low on oil. As the gear degrades, oil pressure drops progressively until the warning light illuminates. At that point bearing surfaces and crankshaft journals can be damaged within seconds of continued running. The failure mode is sudden rather than gradual and often results in total engine loss requiring replacement.

04Timing Chain Tensioner Failure — 4B10/4B11
Does not apply
Does not apply
The 4B10 1.8L and 4B11 2.0L engines use a hydraulic timing chain tensioner that relies on consistent oil pressure and clean oil to maintain chain tension. Neglected oil changes allow sludge to block the tensioner's oil feed, causing the tensioner to lose pressure and the chain to slacken. A slack chain produces a characteristic cold-start rattle that disappears as oil pressure builds. If left unaddressed the chain can skip a tooth or jump timing, causing valve-to-piston contact and catastrophic internal engine damage. Risk escalates significantly beyond 120,000km without tensioner inspection.
Example of the part — not this vehicleThe front of a twin-cam engine with the timing cover off — chain, sprockets and guides.

05Timing belt overdue on the 4G13/4G15 and 4G92/4G93 engines (1.5 is an interference engine)
Does not apply06INVECS-III CVT Belt and Pulley Wear
Does not apply
Does not apply
The Lancer CJ with automatic transmission uses Mitsubishi's INVECS-III CVT featuring a steel push-belt running between two variable-diameter pulleys. The CVT fluid degrades relatively quickly under load and must be replaced every 40,000km; failure to do so causes belt slippage, accelerated pulley wear, and transmission overheating. Once belt slip begins the wear is self-accelerating and the unit typically enters limp-home mode or fails entirely. Rebuilt CVT units are scarce in the NZ and AU market, making replacement with a used unit the most common repair path, though donor unit reliability is also uncertain.

07SST Twin-Clutch Clutch Pack Wear in Stop-Start Traffic (Evo X)
Does not apply08Front LSD Clutch Pack Wear from Track and Hard Street Use (Evo X)
Does not apply
Does not apply
The front limited-slip differential in the Evo X MR and GSR variants uses a mechanical clutch-type LSD. Hard cornering, repeated aggressive launches, and track use accelerate clutch pack wear, causing the LSD to lose its locking ability and behave as an open differential under power. Symptoms are most apparent when accelerating out of tight corners where wheel spin on the inside front wheel indicates LSD slip-through. The LSD fluid must be changed at 20,000 km intervals with correct LSD-specification fluid; neglect accelerates wear. Rebuilding the front LSD requires differential removal and specialist knowledge.

09F4A21/F4A22 4-speed auto 2-3 shift flare (worn reverse/overdrive clutch)
Does not apply
Does not apply
The 4-speed F4A-series automatic in the CE/CK-era Lancer and Mirage is known for a flare on the 2-3 upshift: the revs jump as it changes into third instead of the gear taking up cleanly. Mitsubishi issued a service bulletin covering 1997-2002 Mirage and later Lancers, replacing the reverse/overdrive clutch assembly, drum, seal rings and rear cover with improved parts. Left alone, the slipping clutch wears further until third and fourth gear slip or the box goes into limp mode, and a rebuild is then needed. There is no active recall; the bulletin work was not free.

104B10 MIVEC Cam Oil Passage Sludge & P0011
Does not apply
Does not apply
The 4B10 1.8L MIVEC engine is susceptible to oil sludge accumulation in the Variable Valve Timing oil control solenoid passages and camshaft sprocket oil feed galleries when oil change intervals exceed 5,000 km or conventional mineral oil is used. Sludge restricts oil flow to the cam phaser, triggering P0011 (Camshaft Position Timing Over-Advanced Bank 1) and P0021. Progressive oil starvation leads to intake camshaft lobe and follower wear, particularly on the variable timing lobe profiles. In severe cases, camshaft lobe scoring occurs without further warning beyond the initial DTC illumination.

11SST Clutch Cooling Oil Pump Failure (Evo X)
Does not apply
Does not apply
The SST transmission uses a dedicated electric oil pump to circulate cooling fluid through the wet clutch packs. Failure of this pump causes the clutches to overheat rapidly, leading to accelerated clutch wear, shudder, and in severe cases, clutch pack destruction. The pump failure often manifests as a SST warning light under hard driving or after sustained low-speed maneuvering. The pump is an electromechanical unit that fails through motor brush wear or impeller damage and is not a standard service item, so it is often not replaced until failure occurs.

121.8 GDI (4G93) intake carbon build-up and high-pressure fuel pump wear — Japanese-import cars
Does not apply13Diesel EGR Valve Carbon Sticking & Rough Idle
Does not apply
Does not apply
The 2.0 DI-D diesel variant of the Lancer CJ suffers from Exhaust Gas Recirculation valve sticking in the partially open or closed position due to carbon deposit accumulation on the valve pintle and seat from short-trip urban use. A sticking-open EGR valve introduces excess exhaust gas into the intake at idle, causing rough idle, diesel knock, and misfires. A sticking-closed valve triggers P0401 insufficient flow faults and raises NOx output. The EGR cooler passages on this engine are also prone to carbonisation from low-load operation, compounding the restriction. Symptoms worsen progressively and MIL illumination typically precedes drivability deterioration.

14Crankshaft pulley bolt loosening on the 1.5 (4G15) — recalled twice
Does not apply
Does not apply
On CE Lancers with the 1.5-litre 4G15, the crankshaft pulley bolt can work loose and let the pulley dislodge. If it lets go the engine can simply stop, or the pulley spins on the crank and the power steering pump and alternator stop being driven — heavy steering and a flat battery follow. It was recalled twice: August 2000 (PRA 2000/4410, cars built before 12 February 1999) and November 2001 (PRA 2001/5046, cars built February 1999 to August 2000). The recalls are a quarter-century old and completion on any individual car, especially a Japanese import, is not guaranteed. If a loose pulley has chewed the crank snout keyway, the fix grows from a bolt-and-pulley job into crank machining.

17Manual gearbox synchro binding - hard to select first or second (CE/CK 5-speed)
Does not apply
Does not apply
On the 5-speed manual fitted to the CE/CK-era Lancer and Mirage, the synchronisers can bind so the car becomes hard to get into first or second gear, particularly when cold. It is a commonly reported fault on the equivalent 1996-1998 US Mirage. It usually starts as a notchy change and gets worse; a fluid change with the correct gear oil sometimes helps, but a true synchro fault needs the gearbox opened up or a good used gearbox fitted.

01Corrosion on Japanese-import Lancers — subframe, arches and underbody
Does not apply
Does not apply
Lancers of this era sold in New Zealand are overwhelmingly Japanese used imports, and cars built for the Japanese domestic market were given noticeably less corrosion protection than export-market cars because Japan does not salt its roads. Landed here — particularly in coastal areas — they rust from underneath: the front subframe, inner sills, wheel arch lips, strut towers and the floor around the seat mounts. Mitsubishi has issued front subframe corrosion recalls on Lancer-family vehicles in other markets, which indicates how load-bearing the affected area is. In New Zealand, structural rust near suspension mounting points is an outright WoF failure and repairs are labour-intensive.

02Front Lower Arm Inner Bush Failure & Steering Shimmy
Does not apply
Does not apply
The front lower control arm inner pivot bushes on the CJ Lancer and CZ4A Galant Fortis degrade prematurely due to the original rubber compound hardening and cracking under NZ road and climate conditions. Failure allows the lower arm to deflect longitudinally and laterally under braking and cornering loads, producing vague steering feel, highway shimmy between 90 and 110 km/h, and wander on cambered roads. The bush deflection moves geometry beyond alignment compensation limits, causing accelerated front tyre edge wear. Both lower arms typically require simultaneous bush replacement to permit correct caster and camber alignment.

Mitsubishi Lancer buyer questions
Is the Mitsubishi Lancer reliable?
Like any used car, it depends on the specific example and its service history. Across the 39 documented faults for the Mitsubishi Lancer, the recurring problem areas are engine, body & rust, and electrical. A Mitsubishi Lancer with a full service history and no signs of the issues listed on this page can be a sound buy but each one needs to be checked individually before you commit.
What are the most common problems with a used Mitsubishi Lancer?
We've catalogued 39 known faults for the Mitsubishi Lancer, covering engine, body & rust, and electrical. All 39 are written out in full on this page, with the symptoms to notice, what to inspect, and typical repair costs for each. Free to read, no account needed.
How much do repairs cost on a Mitsubishi Lancer?
Most single repairs on the Mitsubishi Lancer fall between $450–$1,800 at NZ independent-workshop rates. Some of the 39 documented faults cost less and a few cost considerably more, and no one car needs them all. Knowing which ones to look for before you view is what lets you negotiate the price down or walk away.
Should I get a pre-purchase inspection on a Mitsubishi Lancer?
Yes. A Mitsubishi Lancer inspection focused on its known weak points is the single best way to avoid an expensive mistake. KickTyres gives you a guided, model-specific inspection plus a market valuation and negotiation figure for $24.90 far less than the cost of missing one of the faults on this page.
