Known Issues
Known Issues:
Head gasket leaks (particularly on earlier EJ25 engines, though less common on this generation than previous ones), oil consumption, catalytic converter issues, suspension component wear (bushings, ball joints), turbocharger issues on XT models (if applicable), ignition coil failures.
Known Issues Headgasket:
While Subaru addressed head gasket issues in later models, the EJ25 engine can still be prone to external oil leaks from the head gaskets. Internal coolant leaks are less common but possible. The manual details inspection procedures and torque specifications for proper reinstallation.
Known Issues Oil Consumption:
Some EJ25 engines can exhibit oil consumption, often due to worn piston rings or valve stem seals. The manual provides specifications for checking oil level and diagnosing potential causes.
