Known Issues
Piston Slap:
Some EJ257 engines can exhibit piston slap, particularly when cold, due to piston-to-cylinder wall clearance. This is often considered a characteristic rather than a critical failure if it disappears when warm.
Head Gaskets:
While not as prevalent as on some earlier EJ engines, head gasket failures can still occur. Regular coolant checks and maintenance are important.
Clutch Wear:
Due to the high-performance nature of the WRX STi, clutch wear can be accelerated by aggressive driving habits.
Turbocharger Care:
Proper warm-up and cool-down procedures are crucial for turbocharger longevity. The manual will cover these aspects.
