Known Problems

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

One or more power window switch may fail. The affected window may work intermittently before failing completely.

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 intake manifold gasket may develop and external engine oil or coolant leak. In some cases, an internal coolant leak may occur causing coolant to mix with the engine oil. Our technicians tell us that operating the engine  with a coolant/oil mix can result in internal engine damage. Replacing the intake manifold gasket should correct these leaks.

When the heater only works on high, the most common problem is a blower motor resistor. The correct repair is to replace it with a new resistor.

The front struts may show signs of wear, or be excessively bouncy ride at freeway speeds. This may begin to occur at around 75,000 miles.

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

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

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

One or more of the power windows may stop working due to a failed window switch. Failed switches will require replacement.

The automatic transmission shifter may fail, or a wire may break near the shifter causing the ignition key to become stuck in the ignition lock cylinder.

Acid may leak from the battery at the cable connections, resulting in corrosion on the battery cable ends and in the battery tray. A Leaking battery should be replaced and the cables thoroughly cleaned or replaced if necessary.

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