Temperature blend and recirculation doors commonly fail, which can cause the AC modes not to change or the temperature to be different on the left and right sides. If replacing blend air doors, a recirculation door, a door link, or a sub-assembly housing, new heating, ventilation and AC (HVAC) sub-assemblies are available that improve reliability.

When normal alignment practices do not bring components into the alignment specifications, offset upper ball joints are available.

The engine may stall without warning due to a faulty fuel pump relay. Dealers will modify and replace the fuel pump relay free of charge to correct the problem.

The alternator can fail, causing loss of electrical power and possible engine stalling. Dealers will repair the vehicle free of charge (the repair procedure is not available as of the time of this writing).

The power brake booster in these vehicles uses vacuum developed by the engine to provide power assistance to the braking system. Certain vehicles are being recalled because the shell of the vacuum brake booster can corrode and allow water to get inside. The water inside could freeze and limit ability of the brake booster to provide brake assistance. This reduced braking ability can increase the risk of a crash. Dealers will test the brake booster and replace those that fail, and all vehicles will have a diverter shield installed on the brake booster to prevent this from occurring in the future.
