Lancer X (10th gen) · 2007–2017
1.5 MIVEC · 109 hp · 1.6 MIVEC · 117 hp · 1.8 MIVEC · 143 hp · 2.0 MIVEC · 150 hp
Known problems
- Worth watching usually from 50,000 mi (80,000 km)
Steering-rack knock
Symptoms: knocking or clunking from the steering rack over bumps and small road imperfections, felt through the wheel
What to do: Have the rack and its mounts inspected when a knock develops; this is common wear and is fixed by adjusting, rebuilding or replacing the rack.
- Worth watching usually from 75,000 mi (120,000 km)
Jatco CVT wear
Symptoms: overheating, whine or jerky/delayed engagement if the fluid is neglected; the box is reasonably durable when serviced but suffers with heat and old fluid
What to do: Change the CVT fluid regularly (~45,000 km) and avoid overheating it in heavy traffic; a well-maintained CVT can pass 200,000 km, while a neglected one wears early. Have any shudder or slip checked early.
- Worth watching usually from 93,000 mi (150,000 km)
Timing-chain stretch (4B10 / 4B11)
Symptoms: rattle in the first seconds after a cold start; on a badly stretched chain, rough idle and a timing fault code
What to do: Keep oil fresh and at level — chain stretch tracks neglected oil and carbon. If you hear a cold-start rattle, have the chain, tensioner and guides inspected.
- Good to know
Thin paint and localised corrosion
Symptoms: paint chips through to primer easily, and in salted-road climates rust can start at the arches, sills and lower doors
What to do: Touch up chips promptly and treat the underbody for winter; inspect arches and sills on an older car.
- Good to know usually from 37,000 mi (60,000 km)
Throttle-body and intake-pressure-sensor fouling
Symptoms: hesitant throttle response, uneven idle or hard starting as the throttle valve and manifold pressure (MAP) sensor pick up deposits
What to do: Clean the throttle body and MAP sensor when idle or response deteriorates; it usually restores smooth running without parts.
Service schedule
| Item | Interval | Notes |
|---|---|---|
| Cabin filter | every 9,000 mi (15,000 km) | — |
| Engine oil & filter change | every 9,000 mi (15,000 km) or 12 months | halve to ~7,500 km for short-trip/city or severe use — fresh oil protects the timing chain |
| Air filter | every 19,000 mi (30,000 km) | — |
| CVT fluid (Jatco) Important | every 28,000 mi (45,000 km) | CVT cars (mainly 1.8/2.0, also 1.6) — service earlier than the long factory interval; 5-speed manual cars are unaffected |
| Spark plugs | every 37,000 mi (60,000 km) | iridium |
| Brake fluid Important | every 24 months | — |
| Timing chain (no belt) | — | all engines are chain-driven — investigate any cold-start rattle |
Manufacturer-declared fuel economy
| Engine | City | Highway | Combined | Cycle |
|---|---|---|---|---|
| 2.0 MIVEC Lancer X (10th gen) · 2007–2017 | 21 mpg (11.2 L/100 km) | 28 mpg (8.4 L/100 km) | 24 mpg (9.8 L/100 km) | EPA |
Lab-cycle figures, each shown with the cycle it was measured under — the same car under EPA, WLTP, NEDC or JC08 can differ by up to 20%. Real driving always falls short of the declared figure: roughly 10–20% on an EPA rating, 15–30% on a WLTP or NEDC one. That gap is normal, not a fault.

Frequently asked
What are the most common Mitsubishi Lancer problems?
The faults reported most often are: Steering-rack knock; Jatco CVT wear; Timing-chain stretch (4B10 / 4B11). Symptoms, the mileage each appears at and what to do about it are all above.
How often does the Mitsubishi Lancer need servicing?
Engine oil & filter change — every 9,000 mi (15,000 km) or 12 months. The full published schedule is above; your car's own service book always takes precedence.
What is the real fuel consumption of the Mitsubishi Lancer?
The manufacturer declares 24 mpg (9.8 L/100 km) combined for the 2.0 MIVEC under the EPA cycle. Real driving falls short of any lab figure — roughly 10–20% on an EPA rating, 15–30% on a WLTP or NEDC one — and that gap is normal.
Where does this data come from?
Brimly's Vehicle Knowledge Base — the same verified facts the app's AI assistant answers from. Every fault is written up from public sources and then checked by a human before it is published; nothing here is generated on the fly.
