Variant History

Mitsubishi Outlander PHEV Engine History & Specs at a Glance

Common Problems

Mitsubishi Outlander PHEV Engine Problems Repair Cost vs Replacement

The Mitsubishi Outlander PHEV's 4B11 and 4B12 petrol engines are generally reliable but have known weak points. The 4B11 timing chain tensioner and the 4B12 oil consumption issues are the most common reasons owners seek replacement engines through our network. Rebuilt engines from EnginesMarket specialists include upgraded components addressing the original failure point, plus a minimum 12-month unlimited-mileage warranty.

Common failure points and repair options

Timing Chain Tensioner Failure

Affected
Mitsubishi Outlander PHEV (4B11, 2013-2018)
Typical failure mileage
60,000-100,000 miles
Root cause
The 4B11's timing chain tensioner can lose hydraulic pressure, leading to chain slack and eventual failure if not addressed. Cold-start rattle is the classic warning sign.

Repair options

Repair tierDealer priceSpecialist price
Timing chain replacement£1,200-£1,800£800-£1,200
Full Replacement - rebuilt/reconditioned engine£3,500-£5,000£1,800-£3,500
Our recommendation
If you catch the timing chain rattle early, replace the chain and tensioner - it's far cheaper than a full engine. If the chain has already snapped or caused damage, a rebuilt or reconditioned engine with warranty is the sensible choice for any Outlander PHEV worth over £6,000. For very high-mileage examples with poor battery health, consider the scrap value first.

Oil Consumption (4B12)

Affected
Mitsubishi Outlander PHEV (4B12, 2018-present)
Typical failure mileage
80,000-120,000 miles
Root cause
Piston ring wear can cause excessive oil consumption, particularly on vehicles with inconsistent servicing. Failed piston rings allow oil to enter the combustion chamber, causing blue smoke and potential catalyst damage.

Repair options

Repair tierDealer priceSpecialist price
Piston ring replacement£2,200-£3,000£1,500-£2,200
Full Replacement - rebuilt/reconditioned engine£4,000-£6,000£2,500-£4,500
Our recommendation
The 4B12 is a more robust engine than the 4B11, and oil consumption issues are less common than timing chain failures. If oil consumption is mild (under 1L per 1,000 miles), monitor it and keep oil topped up. If consumption is excessive, replacing piston rings is viable - but if the bores are scored, a full replacement engine is the right call.

EGR Cooler Failure (4N14)

Affected
Mitsubishi Outlander 2.2 DI-D (4N14, 2013-2018) - shared chassis with PHEV
Typical failure mileage
60,000-100,000 miles
Root cause
The EGR cooler can leak coolant into the exhaust, causing white smoke, loss of coolant, and potential engine overheating. This is the most common 4N14 failure reported in the UK.

Repair options

Repair tierDealer priceSpecialist price
EGR cooler replacement£700-£1,200£500-£800
Full Replacement - rebuilt/reconditioned engine£5,500-£8,000£3,000-£5,500
Our recommendation
The EGR cooler failure is preventable with regular servicing. If you catch it early, replacement is straightforward and cost-effective. Full engine replacement is rarely justified for the 4N14 diesel unless the engine has been overheated to the point of head gasket failure or crankshaft damage.

Don't Let Engine Failure Write Off Your Mitsubishi Outlander PHEV

The 4B11 and 4B12 engines are fundamentally robust units. With proper preventative maintenance and early intervention at the first signs of chain rattle or oil consumption, most Outlander PHEVs can run well past 150,000 miles. But if the worst happens, EnginesMarket connects you with UK specialists who supply reconditioned and rebuilt units with upgraded components addressing the original failure points, backed by a minimum 12-month warranty - and all at a fraction of main dealer prices.
