Known Issues
Head Gaskets:
EJ25D engines (early phase) are prone to head gasket failure due to coolant passage design. Check for coolant leaks, milky oil, or white exhaust smoke.
Rear Main Seal:
Potential for rear main seal leaks, especially on higher mileage vehicles.
Clutch Wear:
Clutch wear is normal, but frequent hard driving or AWD engagement can accelerate wear.
Oil Leaks:
Valve cover gasket leaks and front crankshaft seal leaks are common.
Radiator Plastic Tanks:
Plastic end tanks on the radiator can become brittle and crack over time, leading to coolant leaks.
