Known Problems

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

The transmission pressure control solenoid may fail causing erratic shifting. Our technicians tell us that partial dis-assembly of the transmission is necessary to replace a failed pressure control solenoid.

The mass air flow or crankshaft position sensor may fail causing the engine to intermittently stall. It may be necessary for the engine to cool down before it will restart.

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.

A Loose or worn gas cap may cause Check Engine Light to illuminate.

The spark plugs should be replaced every 100,000 miles. Our technicians recommend replacing the spark plug wires also at this time.

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

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

The fuel pump may fail causing the engine to stall and not restart.

Extended life coolant may become contaminated and require cooling system service before the recommended 100,000 miles.
Our technicians recommend to replace the fuel system filter every 30,000 miles.
