Common Mitsubishi Problems

L200 Head Gasket / Overheating: Series 4 models especially are prone to overheating if radiators are not maintained, leading to expensive head gasket failures.

Outlander PHEV Battery Degradation: While generally reliable, batteries lose capacity over time. UK models had a 10-year/100,000-mile warranty which is worth checking.

Shogun Rear Subframe Rust: A major MOT killer for Mk3 and Mk4 models; the subframe and its mounting points can rot through entirely.

L200 Chassis Corrosion: All generations of L200 require regular undersealing to prevent structural rust on the rear chassis rails.

Shogun Fuel Tank Delamination: On Mk3 models, the internal lining of the fuel tank can flake off, clogging the fuel pump and injectors.

ASX & Outlander Oil Dilution: Diesel models (2.2 DI-D) used for short trips suffer from rising oil levels due to interrupted DPF regenerations.
