Mitsubishi Outlander

The common-rail injectors on the BSY/DW10BTED4 tend to wear and seize from 120,000–150,000 km. Faulty injection causes engine misfires and increased soot output. Replacement is costly.

Symptoms: Engine stumbling, misfires, cold-start difficulties, check engine light, rough running

The balance shafts on the 2.0 DI-D in the Outlander II/Grandis wear prematurely with neglected oil changes. Characteristic droning noise from the engine bay. Repair is very expensive.

Symptoms: Droning and vibration from the engine bay (especially in the mid-rpm range), check engine light

The BSY/DW10BTED4 uses a timing belt drive with a 120,000 km or 10-year replacement interval. Exceeding it risks engine damage from valve collision. Replace the water pump at the same time.

Symptoms: Engine won't start, loud metallic noise on start attempt

The EGR valve on the 2.0 DI-D BSY cokes up with typical urban and short-trip use. The Outlander and Grandis as heavier vehicles in city traffic are particularly susceptible. Cleaning every 80,000–100,000 km recommended.

Symptoms: Power loss, limp mode, rough idle, increased fuel consumption, check engine light

The turbocharger on the BSY shows shaft wear at high mileage and with neglected oil changes. In the heavy Outlander/Grandis, particularly with frequent full-throttle use. Allow a cool-down period after long runs.

Symptoms: Whistling from turbo, power loss, blue exhaust smoke

Body cavity protection is inadequate from the factory. Underbodies and cavities rust noticeably earlier than the competition without additional treatment. Door bottom edges and sills are particularly at risk.

The wiper motor is inadequately protected against water ingress and is prone to corrosion. In advanced cases the wipers fail completely, which severely compromises driving safety in rain.
