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.
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 spark plugs should be replaced every 30,000 miles and the spark plug boots should be checked for hot spots and cracks.
The anti-lock brake (ABS) accumulator may fail causing loss of power brake assist. (The brake pedal will become very hard.)
A coolant leak may develop from the water pump. This can result in an engine overheating condition. A leaking water pump will require replacement.
The high pressure power steering hose will commonly leak fluid; it should be replaced.
The intake manifold gasket may develop external engine oil leak. The manifold gasket will need to be replaced to correct this issue.
