Overview
The Eclipse Cross is Mitsubishi's small-to-medium coupe-styled crossover, launched in Australia in late 2017 (GK) and heavily facelifted in early 2021 (often called GL) when the controversial split tailgate was dropped for a cleaner conventional rear and the boot grew. It is a monocoque on-road soft-roader sold as ES, LS, Aspire and Exceed. For most of its life Australia only got ONE engine: the 1.5-litre turbo-petrol 4B40 (110kW/250Nm) driving a Jatco-derived CVT in either front-wheel drive or Mitsubishi's electronically controlled on-demand AWD. A 2.2 diesel and a 2.0 NA petrol existed overseas but were NOT sold here. From September 2021 Mitsubishi added the Eclipse Cross PHEV, which shares the Outlander PHEV's 2.4-litre Atkinson-cycle 4B12 petrol plus twin electric motors and S-AWC electric all-wheel drive (no engine-to-wheel mechanical link), a 13.8kWh battery and around 55km of WLTP electric range. The defining buyer notes are the CVT (generally durable but rev-hangy, dislikes neglect and is expensive to replace), the 1.5 turbo's GDI carbon and oil-use tendencies, a few Mitsubishi electrical/software niggles, and on the PHEV the usual plug-in concerns around battery state-of-health, the on-board charger and infrequent petrol-engine use fouling. Mitsubishi's long capped-price-servicing and up-to-10-year conditional warranty make a well-serviced example a sensible, if unexciting, used family buy.

Timing chain / belt / gear
Timing chain (no scheduled belt replacement)
Pros
- Torquey little turbo - 250Nm from low revs makes it easy around town
- Timing chain, no belt to replace
- Long Mitsubishi capped-price servicing and up to 10-year conditional warranty
- Available with genuine on-demand AWD on higher grades
- Proven, widely serviced engine with good parts availability in Australia
Cons
- CVT hangs the revs and gets noisy/buzzy when pushed
- Direct-injection carbon and some oil consumption reported at higher km
- CVT is expensive to replace if neglected and fluid is often ignored
- Real-world economy well above the official figure for a 1.5
- Firm, occasionally clunky ride and average refinement
Known problems
high
CVT rev-hang, judder and costly failure
The CVT lets the engine revs hang high under load with a lot of drone, and some cars develop low-speed shudder, hesitation or surging take-up. Most owners just dislike the feel, but neglected units (no fluid changes, lots of towing or stop-start city use) can overheat and fail, which is very expensive out of warranty.
Fix: Insist on CVT fluid-change history (around every 45,000-60,000km despite 'long-life' claims); apply any Mitsubishi software update for driveability; budget for a unit on a high-km car with no records.
medium
Direct-injection intake-valve carbon build-up
Like most GDI turbo fours the 4B40 can accumulate carbon on the intake valves over time (no port-injection wash on early/most builds), causing rough idle, hesitation and minor misfire at higher km.
Fix: Walnut-blast / intake clean if symptomatic; quality fuel and regular oil changes slow it.
medium
Oil consumption and turbo oil-seal weep
Some 4B40 engines use oil between services, attributed to piston rings/valve seals or the turbocharger oil seals; in worse cases blue smoke or a fouling turbo follows. Worst on hard-driven or oil-change-neglected cars.
Fix: Check oil level and for smoke before purchase; monitor consumption between services; reseal or replace the turbo if it is the source.
medium
Turbo wastegate / boost-control faults
The turbo wastegate/actuator can stick or rattle and boost-control faults can throw a check-engine light, limp mode and power loss, as on many small turbo fours.
Fix: Diagnose actuator/wastegate; replace turbo or actuator if faulty; verify boost behaviour on a test drive.

Timing chain / belt / gear
Timing chain (no scheduled belt replacement)
Pros
- Around 55km of electric-only range covers most daily commutes on cheap home charging
- Smooth, quiet, strong electric AWD via S-AWC twin motors - no CVT drone
- Proven Outlander PHEV powertrain, by far Mitsubishi's most developed hybrid system
- No conventional gearbox or DCT/CVT failure risk in the drive path
- Can run as a normal hybrid when the battery is flat
Cons
- Heavy and thirstier than a normal hybrid once the battery is depleted
- Drive-battery degradation reduces EV range as the car ages
- On-board charger / charging faults are an expensive PHEV-specific risk
- Petrol engine that rarely runs can foul / suffer condensation if never used
- Higher purchase price and more complex (and costly) to repair than the 1.5
Known problems
medium
Drive-battery degradation / reduced EV range
Like all PHEVs the 13.8kWh lithium battery loses capacity with age and cycles, cutting the usable EV range below the ~55km claim; heat, frequent rapid charging and constant 100% charging accelerate it. A full pack replacement out of warranty is very expensive.
Fix: Check state-of-health / EV range on a test drive; confirm the high-voltage battery warranty (typically 8 years/160,000km) is still valid; prefer cars charged to ~80% daily.
medium
On-board charger / charging system faults
PHEV-specific charging electronics (on-board charger, DC-DC converter, charge port) can fail, leaving the car unable to charge from mains or throwing high-voltage system warnings.
Fix: Test both AC home charging and any DC charging before purchase; have HV faults diagnosed by a Mitsubishi EV-trained workshop; replace the affected module under warranty where possible.
low
Petrol engine under-use fouling / fuel ageing
Owners who drive almost entirely on electricity can let the 2.4 petrol sit unused for long periods, leading to stale fuel, condensation, and the system periodically force-running the engine to burn off fuel and exercise it.
Fix: Run the petrol engine regularly and keep fresh fuel; let the car complete its engine-maintenance cycles; not a defect but a PHEV usage habit.
