2005 Pontiac Montana 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.

Illumination of the Check Engine Light can be caused by a loose or worn gas cap.

The rear light socket plate may fail causing a brake light or other rear light to stop working.

Certain sport utility vehicles fail to conform to the requirements of Federal Motor Safety Standard # 135 "Passenger Car Brake Systems" To meet the standard, vehicles must not move for 5 minutes when stopped on a steep hill with the parking brake applied and the vehicle in neutral. Some of these vehicles failed this test. When the parking brake is released the driver may notice unintended braking while accelerating, decelerating or coasting.

I have a 2005 Montana. It has been a very reliable car. I have put quite a few brake pads on the car seems to go thru them and then they squeal. I replace about every 30000 miles.
