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.

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 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.

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.

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

The serpentine belt tensioner pulley may wear out. Our technicians tell us that in order to get a new pulley from General Motors you must purchase a complete belt tensioner assembly.

 

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

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

 

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

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

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.
