Known Problems

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.

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

 

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.

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

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 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.

The mass air flow or crankshaft position sensor may fail causing the engine to stall intermittently. Proper diagnoses will be necessary to determine the cause of any stalling condition.

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

The spark plugs should be replaced every 30,000 miles and the spark plug boots should be checked for hot spots and cracks.

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.

An engine oil leak may develop from the rear of the engine. This is commonly caused by a failed oil pump drive o-ring seal. The leaking o-ring should be replaced to correct this concern.
