Known Problems

The fuel pump can fail causing the engine to stall and not restart. Our technicians highly recommend to replace your fuel filter every 30,000 miles to help prevent undue strain on the fuel pump.

The anti-lock brake (ABS) pressure modulator valve assembly may fail internally causing the ABS light to illuminate.

If the ABS light on the instrument panel illuminates, our technicians recommend checking the brake lamps first. It could indicate that a brake light is not working or has burned out.

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 the engine to stall and not restart. Our technicians recommend replacing the fuel filter every 30,000 miles to help prevent undue strain on the fuel pump.

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 ignition switch may fail causing a no start condition. This is not generally a theft system (passlock) issue because the security light does not illuminate or flash.

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

Timing gears may wear causing a mild to severe knocking noise from the front of the engine. Replacement of the timing gears is 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 trunk pull down switch may fail causing the trunk lid not to close completely. Our technicians tell us that the failed switch can be replaced without changing the complete pull down motor assembly.
