Known Problems

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


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

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.

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

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

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 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.


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

Our technicians highly recommend that the engine coolant be replaced every 30,000 miles.

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.
