2003 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 high pressure power steering hose will commonly leak fluid and should be replaced if this is the case.

2003 Pontiac Montana Reviews

Purchased a 2003 Montana with about 20,000 miles on it. The thing with the Montana is that a lot of annoying little things go wrong. The fuel gauge does not work, warning lights go off when there are no actual problems, lower plastic side panel gets knocked off in a car wash, doors have to be unlocked/locked and unlocked again to open ... it does not inspire confidence. I am very fortunate t...

I bought mine used, and it came with electrical problems. Still hunting some of them down even now, a year later.

The van looks good and the interior is good. It does have a lot of minor maintance issues on a regular basis. Right now our transmission gear selector cable is broke so it's stuck in drive. The wiper blade transmission needs replaced, and the ABS trouble light it on.
