An automatic transmission fluid leak may develop from the rubber section of a transmission cooler line. In some cases the rubber section of hose can be replaced. In others, the complete cooler line must be replaced to correct this type of leak.

Problems with anti-theft systems using the raised-chip key can prevent the car from starting. The wires in the steering column to the ignition lock cylinder tend to break. The key and ignition lock cylinder should be replaced to correct this condition.

The air conditioning system can be prone to refrigerant leaks and failure of one or more pressure sensors. The AC pressure sensors should be checked for proper operation when ever the AC system is serviced.

The trunk pull down switch may fail causing the trunk lid not to close completely. Our technicians tell us that the failed switch can be replaced without changing the complete pull down motor assembly.

The intake manifold and valve cover gaskets can develop external engine oil leaks.

The anti-lock brake (ABS) accumulator may fail causing loss of power brake assist. (The brake pedal will become very hard.)

The high pressure power steering hose will commonly leak fluid; it should be replaced.

The fuel pump may fail causing the engine to stall and not restart. Our technicians recommend replacing the fuel filter every 30,000 miles to help prevent undue strain on the fuel pump.

The Engine Control Module (ECM) can fail causing stalling, and engine and transmission drivability concerns.

The auto level ride compressor may fail causing the rear of the vehicle to ride to high or too low.

The mass air flow or crankshaft position sensor may fail causing the engine to stall intermittently.

Vehicles with the optional CRT dash may have the display fail. Our technicians tell us that the CRT unit will need to be sent out to a specialized repair facility for repair.
The ABS master cylinder assembly may fail internally causing the ABS light to illuminate.

A coolant leak may develop from the water pump. This can result in an engine overheating condition. A leaking water pump will require replacement.
