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.
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.
Illumination of the Check Engine Light can be caused by a loose or worn gas cap.
One or more power window switch may fail. The affected window may work intermittently before failing completely.
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.
