The hold down nut for the upper front strut area can become loose, causing a knocking noise. This can be repaired without removing the strut assembly.

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.

Going over large bumps in convertible models may cause the roll bar to deploy, rendering the roof inoperative. Special tools are generally required to return the roll bar to its stowed position.

Computer control modules for the seats and doors, the CD changer, and the brake lamp switch tend to fail.

A vibration felt through the center floor of the vehicle can be caused by driveshaft flex discs, which crack and shred, causing excessive driveshaft movement. Not repairing these can cause damage to the driveshaft center support bearing, or, in the worst case scenario, damage to the transmission or differential.

The mass air flow sensor can fail, resulting in poor fuel economy and Check Engine Light illumination.

The heater case for the center vents can crack near the stop sensors. If the stops break, the control motor will not know when to stop and will run continuously.
