Mitsubishi Eclipse Cross GK
Weaknesses, engine ratings and buying advice
The Mitsubishi Eclipse Cross GK (2017-2021) is a compact crossover that punches below its weight class in refinement but comes with Mitsubishi's 10-year/100,000-mile powertrain warranty and the S-AWC all-wheel drive system from the Evo lineage. Two engines: the 4B40 1.5L turbo (the only US option) and the 4N14 2.2L diesel (global markets, not North America).
The 4B40 is adequate but the CVT pairing is the weak link. The INVECS-III CVT shudders, surges, and responds with delay — worst on 2018 builds. Mitsubishi's ECU/TCU software update ($200-400 at a dealer) legitimately fixes most complaints. Without the update, the behavior feels broken. With it, the CVT is tolerable. CVT fluid changes every 25,000 miles are mandatory — Mitsubishi calls it lifetime fluid, which is optimistic. The 4B40's MIVEC timing chain stretches from around 100,000 miles: cold-start rattle that disappears after warm-up is the warning sign. A jumped chain means valve-piston contact and a dead engine.
The 4N14 diesel is durable when properly maintained — timing chain issues appear later (around 75,000 miles) and the DPF needs highway runs to regenerate. Short-trip city driving clogs the DPF by 37,000 miles. If the previous owner only did school runs, budget for a DPF cleaning or replacement.
2018 is the year to avoid — highest complaint rate across NHTSA and CarComplaints. ECU software immature, CVT calibration rough, forward collision system falsely triggering on hills. 2020-2021 are significantly better: resolved software, lower complaint density, and owners with 50,000+ miles reporting trouble-free driving.
Test-drive checklist: CVT: any shudder, surge, or delayed response during gentle acceleration? Cold start: listen for timing chain rattle lasting more than 2-3 seconds (100,000+ mile cars). Brake pedal: pulsation at highway speed = warped rotors (documented on 2018 at 13,000 miles). Cabin smell: fuel or oil odor with HVAC on fresh air mode (2018-2019 turbo seal concern). Check door handles — the plastic breaks.
2026 market: 2018 high-mileage from $9,000. 2020-2021 with 40,000-60,000 miles: $16,000-$20,000. Insider pick: 2020 or 2021, manual service history showing CVT fluid changes, under 60,000 miles — the powertrain warranty may still have years left, and the software was sorted by then.
Generations
Engine Overview
The Mitsubishi Eclipse Cross GK is available with 2 engine variants — from 148 to 163 hp.
Strong 2.2-litre diesel with common-rail injection. Good torque for SUV use, but EGR and DPF are maintenance-intensive. Timing chain instead of belt.
- !! Piezo injectors failed from 150,000 km
Piezo common-rail injectors are sensitive to fuel quality. Removing and refitting all 4 injectors costs around 500 EUR in labour plus 700 EUR per failed injector for Bosch reconditioning.
Symptoms: Rough idle, stumbling under acceleration, overconsumption, starting difficulties - !! Oil dilution from DPF regeneration from 80,000 km
Diesel fuel enters the engine oil during DPF post-injection. Oil level can rise rapidly (up to 1 litre per 1,000 km). Diluted oil loses its lubricating properties and endangers the engine.
Symptoms: Engine oil smells strongly of diesel, oil level rises instead of dropping, increased engine noise - !! EGR valve and intake tract blocked from 100,000 km
The EGR valve and intake swirl flaps block with soot deposits from the exhaust system. Short-trip driving accelerates the process considerably.
Symptoms: Check engine light, power loss, rough idle, increased fuel consumption
+ 1 more engine weaknesses + vehicle weaknesses
Modern 1.5-litre turbo with combined direct and port injection — the dual injection reduces intake valve carbon build-up. Early production vehicles from 2018–2019 had documented oil consumption problems. The timing chain should be inspected with neglected oil changes from around 160,000 km.
- !! Timing chain rattles at high mileage from 160,000 km
The 4B40 is one of three Mitsubishi engine codes known for timing chain wear. Above 150,000 km and with long oil change intervals the chain stretches and the MIVEC system is compromised.
Symptoms: Metallic rattling on cold start from the engine front drive, settling down after warm-up; power loss; rough idle at high mileage - !! CVT gearbox wears prematurely from 120,000 km
The INVECS-III CVT gearbox shows first signs of wear between 100,000–150,000 km with irregular oil changes. A complete gearbox replacement is costly; a CVT oil change every 40,000–60,000 km is strongly recommended.
Symptoms: Juddering on pull-away or accelerating from rest, delayed throttle response, unusual noises from the gearbox at low speed - !! Elevated oil consumption in early production from 40,000 km
First-series production vehicles from 2018–2019 showed documented elevated oil consumption of up to 1 litre per 1,000 km. Mitsubishi acknowledged the issue; later production years are significantly less affected.
Symptoms: Noticeably dropping oil level between oil changes, slight blue smoke from exhaust under load, oil level warning before the normal service interval

Vehicle Weaknesses
| Weakness | Cost | |
|---|---|---|
| Recall: autonomous emergency braking activates without cause The Forward Collision Mitigation system can misread situations and trigger emergency braking with no obstacle present. This significantly increases the risk of being rear-ended by following traffic. Symptoms: Unexpected hard braking with no visible obstacle, collision warning alert sounding for no reason | Low | |
| Software fault in the stability control A software fault in the Active Stability Control (ASC) can affect additional driver assistance systems. Affected model years: 2016–2018. Fixable via software update, but potentially dangerous if the recall is missed. Symptoms: ASC warning light on, driver assistance systems respond with delay or not at all, unexpected handling behaviour in corners | Low |
