Transmission issues
- Erratic shifting: The automatic transmission may have problems with rough or erratic shifting.
- Stuck in gear: The transmission can get stuck in a lower gear.
- Delayed engagement: Delayed shifting, especially between park, drive, and reverse, can occur due to internal component wear or control system issues.
Electrical and other systems
- Faulty TIPM: A defective TIPM is a known cause of various electrical problems, such as the engine not starting or stalling, dimming lights, and the battery light coming on.
- Alternator failure: The alternator can fail, leading to dimming lights, slow cranking, and a dead battery.
- Electrical issues: Other electrical problems may include the radio and remote keyless entry not working correctly.
- Knocking AC compressor: Owners sometimes report a knocking noise coming from the AC compressor.

- Squeaking brakes: Squealing brakes are a common complaint reported by owners.
Interior and body
- Heater failure: The heater core is a weak point and can plug up, resulting in heat only on one side of the car.
