Known Issues

Head Gasket Leaks:

Less prevalent than previous generations, but still a potential concern on the EJ253, particularly if overheated or poorly maintained. Look for external coolant leaks or coolant in oil/exhaust.

Catalytic Converter Failure:

Can occur due to age, misfires, or oil consumption. Symptoms include reduced power, check engine light, and sulfurous smell.

Wheel Bearing Wear:

Common on AWD vehicles, especially in areas with road salt. Grinding or humming noise from a particular wheel corner.

Automatic Transmission Issues:

Some reports of shuddering or hesitation, often related to fluid degradation or valve body issues. Regular fluid changes are critical.

HVAC Blend Door Actuators:

Can fail, causing improper air temperature or vent selection.
