Evaporative Emission Control System:
Issues with the EVAP system (e.g., purge valve, vent solenoid, charcoal canister) can trigger check engine lights.
Suspension Components:
Worn ball joints, tie rod ends, and wheel bearings are common with mileage, affecting steering and ride quality.
Exhaust Manifold Cracks:
Some 4G63/4G64 engines may develop cracks in the exhaust manifold, leading to exhaust leaks and ticking noises.
Power Window Regulators:
Window regulator failure is a common electrical/mechanical issue, often related to the motor or plastic guides.
Automatic Transmission Harsh Shifting:
Some early automatic transmissions may exhibit occasional harsh shifts or delayed engagement, often related to solenoid issues or fluid degradation.
