The heating, ventilation and AC (HVAC) heater box is susceptible to mildew buildup. This can result in a musty odor from the HVAC system, most noticeable when the system is first turned on.

Torque thrust bushings in the front suspension may crack and leak oil, this causes steering alignment problems and excessive tire wear. Another symptom of a worn bushing is a clunk or thud noted when turning, on hard acceleration, or hard braking.
