Known Issues
|
|
Common Problems:
|
Potential issues include premature wear on suspension components (ball joints, control arm bushings), occasional issues with the electronic throttle body, and potential for oil leaks from valve cover gaskets. The 4-speed automatic transmission is generally robust but can exhibit wear if not properly maintained. Some owners have reported evaporative emissions system (EVAP) codes.
