I had no heat in my van and took it in to see what the problem was. The automotive place that I took it informed me the gasket was leaking fluid and needed to be repaired immediately or it could seize the motor. I was also informed that these vehicles were know for this problem. The cost was to repair it was in excess of $850. A sum which I could not afford but had to put on credit as I need the vehicle to go back and forth to work. If this make and model are famous for this problem why have they not been recalled. It would sure be a gesture of good will on pontiac if they did.
2001 Pontiac Montana engine complaints
Page 2 of 2: complaints 11 to 38 of 38, newest first, as owners wrote them.
The air conditioner compressor has failed and my mechanic said he has had a rash of failures with the gm products, in fact he received a tech notice to the effect that he could expect a lot of trouble with this product. I called gm with no satisfaction, with so many failure they should take some responsibility for this failure. The cost for this item installed is over $800.00 and for anyone on retirement this is a major expense. I would like to know how many failure occurred and how many complaints gm has received over this. I would think they would be afraid to recall this product maybe it would put them out of business as they already are in deep trouble for not selling a good product. Thanks.
Dexcool coolant leakage signs out of intake manifold, service professional reported it as a problem with gm 3.4 engines and would lead to costly engine repair if not fixed. Replaced gaskets etc cost $956. 66000 klm.
Coolant leak at intake manifold gasket.
Vehicle was not producing heat for occupant compartment. Noticed that coolant was low. Took vehicle to dealer with prior knowledge from your site regarding the intake manifold issues with the montana and other gm vehicles. The intake manifold on my vehicle has failed, and is leaking coolant. No coolant ever reached the ground, as it was evaporating on the engine. There is a petition in line with over 10,00 signatures requesting a recall for this issue.
I had the oil changed and then a few days later the van developed a leak of a red/pink fluid. I took it in to the place where I had the oil changed and then to a local pontiac dealer who also found the same problem. The problem is that the lower gasket went bad. It would take 1200 to 1500 usd to replace it. Both the local pontiac dealership and the goodyear tire dealership that first changed my oil said that it they found it a common replacement on this engine, the 3.4 l gm.
Bought a 2001 pontiac montana with 102,400 miles on it and within three days of ownership the intake gaskets are blown. Repairs are estimated to be $700-$900 without knowing it has done more damage than that. Looked online and found a website that over 9600 people have signed that they had problems with that same engine 3.4l v6. There has been no recall from gm and I think that there should be. Why are we stuck with a bill that high, when it supposedly got rectified in 2002 vehicles. I am sure that there is more people out there that have had the same problems with the head and intake gaskets on these vehicles that has not yet signed the petition. The website address is: http://www.petitiononline.com/gmcnsmrs/petition.html please review! Thank you.
Car began leaking engine coolant from the back of the engine with only 60,000 miles on the odometer. Upon examination, it was found that the coolant leak was coming from the lower intake manifold gasket. This car has always run hot (between the half way mark and the red area of the gauge). The car finally overheated. The dealership said that there was no coolant in the engine, however the burp tank was nearly full, with no spillage. The dealership insisted that it overheated because of the leaking intake manifold gasket. We reluctantly agreed to replace the gasket to a tune of $1,376.00. The car still runs too hot in my opinion, but has not yet overheated.
I bought a 2001 pontiac montana w/40,900 mi.in july 2004, on 8/18/2005 the head gasket blew out w/44,800mi.I towed to local garage where I was told to take to the dealer where I bought it, because of the "well known problems with the 3.4l engine cooling system" I have been quoted a price of $1325.00, gm said that they will pay $300.00
Intake manifold gasket leaking causing dexcool to leak into engine. Gasket had to be replaced. Gm has issued a service bulletin about this problem and will do nothing to help the consumer. Service bulletin # 03-06-01-010 be aware!!!!! Bulletin says new gasket must be made from a different type of material in order to correct problem. If this is the case why should we have to cover the expensive repairs???? Somthing has to be done!
I own a 2000 chevy lumina and a 2001 pontiac montana both have 6 cylinder engines and I have had to replace the head gasket on both of these vehicles. One has 50,000 miles and the other has 70,000 miles. The mechanic that did the repairs said he is replacing the head gasket gm's 6 cylinder vehicles all the time.
I took my van for a free safety check and the mechanic said I had an intake leak which could do some major damage if it wasn't repaired. I took it to the dealership, and they agreed it was leaking, and found a tie rod problem. Along with those problems they said my tensioner on my front seat belt broke. These repairs are over $1,000. If all these other people are having the same problem I would sure like an explanation. My dealership said it is a common problem with these vans. That sure sounds like the vehicle should be recalled!
After checking this web site, I found 8 recalls on my vehicle. I have never recieved a notice from gmor pontiac on any of these recalls. In addition, while the car was still under warranty, there was an antifreeze leak into the manifold and that problem has not been listed in the recall items. I was told it was a common problem by the dealership. Additionally, after several complaints about my car horn - honking sporadically the dealership was unalbe to find the problem. I have had the car 4 years and this has occurred at least 10 times.
Leaking dexcool, needs mainifold gasket, very common problem with montanas and gm is aware of it and released a service bulletin on it # 03-06-01-010 requiring a new intake manifold gasket be installed but at owners expense. Crazy!
2001 pontiac montana with 38k mi. Observed coolant loss with no visible leak. Dealer diagnosed intake maniforld failure, repair cost of $971, no warranty coverage.

Gas leaking under the driver seat and under the hood. Also, gas was pouring out from the motor. *la the window failed to open, the consumer is currently waiting on a new motor. The rear brakes were leaking, the tie rods had to be replaced because they were loose, the left rear stuck became stuck, when the gear was taken out of park and placed into drive and the consumer proceeded to accelerate the vehicle jerked, the engine light illuminated, the dealer determined the emission system was dragging, the driver side mirror vibrated, the bumper cover was loose. When the consumer attempted to turn the key in the ignition, the vehicle did not start, the dealer was unable to duplicate the consumer's concern. The fuel pressure regulator was leaking and the fuel filter was replaced. The vehicle would not go over 10 MPH, the vehicle shifted and then returned to normal speed. The plastic on the drivers seat was loose.
A/c condensor replaced in april 2002....evap core has large hole in it has to be replaced june 2003..currently no A/C service engine light has given false signals since ownership ..problem cannot be identified..
Pontiac montana--found a coolant leak around the intake manifold--this is a known problem that gm does not seem to want to address (much info on the internet pertaining to very angry gm owners)--luckily (maybe) the problem will be fixed "forever".
Intermittently when air conditioner is operating, we get a noxious chemical smell from air vents. Odor lasts for several minutes. This is not coming from outside because we are circulating inside air. We see no pattern to this. It happens at times when the temperature is very hot and also when temperature is moderate. We have had the montana to the dealer three times. They cannot come up with any fix. We are concerned that this may be detrimental to our health. The car stays cool, it's just the awful smell. The cabin filters are perfectly clean.
A malfunction within exhaust system is causing fumes to escape, and resulting in driver and passengers becoming ill. Dealer has yet to be contacted. Please provide further details.
The vehicle has stalled 5 or 6 times in the 4 1/2 months since I have owned it. The first time I had just left work. About 1 mile from work at about 20 MPH it stalled. This was a 2 lane residential area. I was able to fight off the panic, put on my flashers, and had just enough momentum to make it to the next block and coast into a storefront parking area. My husband suggested that I should shift to neutral and restart the vehicle. Stalled on residential 4 lane highway. I had just exited the highway and was traveling at about 30 MPH. The vehicle stalled. I shifted to neutral and restarted. Stalled at about 35 MPH through rush hour traffic and I was on a 4-lane bridge. This time I was in the right lane, thank goodness, because again without any noise or warning lights/messages the vehicle stalled.stalled traveling to work on 4 lane divided highway at about 65 MPH. I was coasting down a long hill toward my exit. The vehicle stalled, I shifted to neutral and it would not restart. I was able to coast to the exit and then to the side of the road. The vehicle did restart after several attempts.stalled on my way to work on a 6 lane divided highway at roughly 70 - 72 MPH. I was in the center lane with vehicles on the left and right. When the vehicle stalls, the headlights, radio, heater, etc... Continue to operate without interruption. The motor completely stops working, however there is no power brakes and no power steering.
Oil filter located next to the starter w burned a hole in air conditioner line. Dealer has been contacted. Please provide further details.
Freon splashed out through engine compartment. Dealer has repaired vehicle. Please provide further details.
