Known Problems

The power door lock actuators may become slow to operate or stop working completely and require replacement.

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.

The anti-lock brake system (ABS) front wheel speed sensors are prone to failure. When a sensor fails, the ABS warning light may illuminate and/or the ABS system may activate erratically.

A coolant leak may develop from the water pump. This can result in an engine overheating condition. A leaking water pump will require replacement.

The rear window defogger may stop working due to a wire terminal broken off of the rear glass. Our technicians tell us that terminal can be reattached using a special glue or silver solder.

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. Running the engine with a coolant/oil mix may result in engine damage. Replacing the intake manifold gasket should correct this issue.

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

It is common for the fuel level sensor in the fuel tank read the fuel level incorrectly. The sensor must be replaced to correct the condition. Our technicians recommend having the complete fuel pump module replaced on high mileage vehicles.

A dirty throttle body may cause a lower than normal idle and possible stalling condition. Performing a throttle body service will commonly correct this concern.

A rattling noise may develop from the AC belt tensioner. This can be caused by an internal fault with the AC compressor, AC performance may also be diminished when this occurs. Our technicians tell us that replacing the ac compressor will commonly correct this concern.

 

The muffler heat shield may become loose on the muffler causing a rattle or popping noise. Our technicians tell us there is a kit available from GM to correct this problem.

The battery may leak acid at the battery cable connections. As a result corrosion may form on the battery cable ends. Leaking batteries should be replaced and the cables need to be thoroughly cleaned or replaced if necessary.

A poor electrical ground under the battery tray may cause the ABS warning light to illuminate. Our technicians tell us that cleaning and properly securing this ground and also the main ABS ground on the frame rail below the drivers door may be necessary.

The anti-lock brake system (ABS) pump may stay running after the ignition is turned off causing the battery to go dead. Our technicians tell us that the ABS control module should be replaced to correct this fault.
