Known Problems

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

The water pump may develop a coolant leak resulting in an engine overheating condition.

 

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.

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 crankshaft position sensor, ignition module, and/or powertrain control module (PCM) may fail resulting in illumination of the Check Engine Light with ignition system related fault codes stored in the PCM. Patience is necessary when dealing with this specific situation as normal diagnostic procedures are not effective. In many cases, the best option is to replace parts, one at a time until the fault is corrected.

The exhaust gas recirculation (EGR) tube which connects the EGR valve to the intake manifold may develop an engine vacuum leak, causing the Check Engine Light to illuminate with code P0171 and/or P0174 stored.

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 power windows may stop working due to a failed window motor or switch. Proper diagnoses will be necessary to determine the exact cause.

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.

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 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.

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

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

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

The intake manifold gasket may develop external engine oil leak. The manifold gasket will need to be replaced to correct this issue.
