Known Problems

Illumination of the Check Engine Light can be caused by a loose or worn gas cap.

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, the transmission system should be completely flushed.

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

Extended life coolant may become contaminated and require cooling system service before the recommended 100,000 miles.

The high pressure power steering hose will commonly leak fluid and should be replaced if this is the case.
