RepairPal has identified the most common problems with the Pontiac Montana based on complaints from actual vehicle owners. We'll tell you what the problem is and what it'll take to fix it.
Corrosion at the fuel tank to body harness may cause the Check Engine Light to illuminate or a crank no start condition. This corrosion issue is most commonly caused by a water leak inside the vehicle. Any damaged wiring or connectors will require replacement.
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.
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 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.
