Known Issues

Head Gaskets:

While boxer engines can be prone to head gasket leaks, the EJ253 in this generation is generally considered more robust than earlier Subaru engines. However, early detection of coolant loss or white smoke is crucial.

Catalytic Converter:

Potential for catalytic converter failure, especially on higher mileage vehicles, often due to underlying engine issues or fuel contamination. Manual provides diagnosis.

Suspension Noise:

Front and rear control arm bushings, sway bar links, and strut mounts can wear over time, leading to clunking or rattling noises. The manual details replacement procedures.

Cv Axle Boots:

Torn CV axle boots can lead to grease loss and damage to the joint. Regular inspection is recommended.

Ac Compressor Clutch:

Some reports of AC compressor clutch failure or engaging intermittently.
