2001 Pontiac Montana 3.4 Liter from North America


A real electrical nightmare


My ignition would not work due to communication problems between key and sensor.

Transmission would not shift out of second gear due to faulty sensor in transmission.

Rear windows will not work.

General Comments:

This vehicle is very well appointed and performance is good. When it is working properly that is. I have had problems with electrical and electronic issues since day one. Transmission problems have plagued me since approximately 85000 km. This problems is back as I type this and sensor was replaced less than three months ago.

I have a 2000 Pontiac Montana. I have loved it since day one except for the electrical problems. It now has 290,000km on it and I am having some sort of transmission problem. For some reason it will not shift into fourth and overdrive. I have taken it in to a few different shops and no repairs have been done. I know the mileage is extremely high so I assumed it would be the transmission, but so far that has not been the diagnosis. Any ideas??

Avoid buying, even with low miles


Started with recalls.

Was not running smooth, injector flush and fuel filter.

Transmission shudder.

Transmission flushed.

Transmission trashed.

Replaced transmission.

General Comments:

This van is having more problems than I can handle. Transmission went out after Pontiac dealer flushed it.

Dealer wanted $2500 for a new on installed. Van only has 57000 miles on it and it's never pulled a trailer or driven in hilly places.

I will trade this van off and find something with less costly problems.

Good looks, but will cost you..


~150k - intake manifold seal - mechanic says he does these before first tune up on Montanas. Cost $700. Did spark plugs while in there... wires were welded on to tops - took 2-3x longer to hack off wires and extricate plugs - cost ~ $300.

Mechanic thinks DEXCOOL may be the problem, since he has done many GM engines with these gaskets. Replaced Dexcool with regular antifreeze.

~140k - wipers broken again. Froze on to windshield, didn't free them. Could not turn them off fast enough - they killed themselves. $100 for some unknown component. Terrible design, especially where it snows.

~130k - water pump.

~120k - wiper park problem. Up here in Canada, snow collects at bottom of windshield where wipers want to park. If they are blocked at all, they kill themselves trying to park. New wiper module - $250.

~110k - replaced EGR valve. $150. check engine light on again - phantom codes - no diagnosis.

~100k - Dash lights burn out easily. They are also not easy to repair like the old days. Cost a couple of hundred to replace a few bulbs, since dash has to be pulled and new bulbs soldered in.

~75k - Front wheel bearing started howling - found a used one and replaced it...$250.

~20k - check engine light always coming on. replaced a few O2 sensors.

General Comments:

I like the look of the Montana. I bought it because my 98 Chevy Venture has given no real trouble, has 300k and have had no issues at all with it. Get 100k out of fr brakes, never done rear brakes.

The vehicles are mechanically identical, yet I hear and read problems galore for the Montana, and cannot figure out why. Are more sold? Are there two different lines in Doraville, GA - a good one and bad one?

Van is hard to resist with 0% financing and deep discounts. So many on road, lots of mechanics can fix them, although not a lot of knock off parts even years later, which is strange.

All tolled, get the Venture. I don't know why it has fewer problems - I think they sell more too. This forum has few messages on Venture problems, way more Montana issues I see.

Check engine light always coming on in both vehicles - usually O2 sensor or EGR or unknown codes. At least in 98 venture light goes off - Montana stays on til reset.

I'm just inquiring if anyone has had any resolution with their dealer or GM in regards to the intake manifold leaking coolant. I just brought my 2000 Pontiac Montana in and it will cost me $1500 to repair. I checked on the INTERNET and this seems to be a common problem in fact the mechanic lifted the hood and looked immediately at the manifold.
