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.
Contaminated brake fluid can cause problems in the brake system and it should be flushed every 60,000 miles.
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 rubber section of an automatic transmission cooler line may develop a fluid leak . In some cases the leaking section of hose can be replaced. In others, the complete cooler line must be replaced to correct this concern.
The cam sensor interrupter (magnet) may become demagnetized and/or fall off of the camshaft gear causing the Check Engine Light (Service Engine Soon) light to illuminate. On higher mileage vehicles it would be advisable to replace the timing chain and gears if this problem were to occur as the timing cover must be removed to replace the interrupter.
The engine temperature sensor wire for the engine temperature gauge, or warning light, may touch the rear exhaust manifold causing a short to ground causing erratic operation of the temperature gauge or warning light.
The steering may develop a clunk type noise from the upper intermediate steering shaft. Our technicians tell us that you should check with your local GM dealer to find out what the latest repair is for this condition.
