Known Problems

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

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.

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 head light switch may fail causing the head lights to become inoperative.

Power seat motors and seat position sensors may fail causing the power seats to act erratically.

You may be able to prevent transmission problems by servicing the transmission and inspecting the fluid every 30,000 miles. If the fluid is dark or burned then the transmission system should be completely flushed.

The spark plugs should be replaced every 30,000 miles and the spark plug boots should be checked for hot spots and cracks.

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

The AC compressor may develop an abnormal noise or refrigerant leak, requiring replacement.


The fuel injectors may short out electrically causing a rough idle condition.

Our technicians highly recommend that the engine coolant be replaced every 30,000 miles.

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.

Brake fluid can become dirty and may cause problems in the brake system; it should be flushed every 60,000 miles.
