Known Issues
Head Gaskets:
While not as prevalent as in earlier EJ engines, potential for head gasket leaks can still exist, particularly with the EJ253. The EZ36D is generally more robust.
Cv Axle Boots:
Tear of front axle boots can lead to grease loss and eventual CV joint failure.
Brake Wear:
Front brake pads and rotors can wear relatively quickly due to the weight of the vehicle and AWD system.
Evaporative Emission Control System:
Issues with the EVAP system, such as faulty purge valves or canister vents, can trigger check engine lights.
Suspension Bushings:
Wear in control arm bushings and sway bar bushings can lead to clunking noises and imprecise handling.
