I own a 2000 pontiac montana,in the past 2 years I have had to replace the waterpumpx2 and intake manifold gasket x2. The gasket lasted 18 months and the waterpump 3 months. I feel that putting 1400.00 dollars into a vehicle within 18 months for the same parts is outrageous. The serviceman however stated the warranty was 1 year. Something seems very wrong with this picture.

On sept 26, 2006, I have my pontiac montana my 2000 vehicle service in a dealer for issue of engine vibration occasionally. The repairing fee is about $1000 to replace spark plug and coils. At 5:36 pm of during my driving back home in I-696, my vehicle engine suddenly stop running at about 75 mile/hour which made me almost become involved in a deadly accident. At this time, I called the dealer to inform this issue and dealer made a note. When the engine stopped running, the dic was lighting up without any information. I came back to the dealer and they were not able to find anything wrong. I was asked to USA a recording data tool, however, the next a month, the vehicle was running ok without incident. Therefore, I stopped recording data for the vehicle. In january of 2007, the same problem began to happen again. 3 times when I driving the vehicle at 60 to 75 mile/hour, the vehicle engine stop running suddenly if the brake was pushed. Then I went back to dealer again for trouble shooting on 1/4/07. They still can not find anything wrong and then schedule to a full check on 1/9/07. However on 2:30 pm of 1/8/07, the vehicle can not be running and has to tow to dealer again. In the meantime, I called gm and dealer to report this incident. I had twice in a very dangerous situation and put my family and myself life in a very harmful situation. Gm give me a case number 71-476-171970. The dealer informed me that they can get vehicle started but can not resolve the issue of engine suddenly stopping with brake pressed. I need to pay $711 for the vehicle running and then go from there. The dealer and gm had a talk, then gm representative told me she will pursue to reimburse me the repairing fee. Then after 4 days gm told me again they will not to reimburse me the money now since I am scared for the engine stop issue, I can not drive vehicle over 65 mile/hour.
Intake gasket leaking coolant. This is a gross misconduct on behalf of gm allowing these to fail without any compensation. No events leading up to this failure...just drive normally. Consequences are $1200 to replace a gasket that should have lasted more than six years.
2000 montana leaked coolant from lower intake gasket. *ts
My 2000 pontiac montana has coolant leaking into the engine through the intake manifold. I noticed the problem today when I changed the oil. Problem has not been corrected yet. At about 50,000 miles I had to start adding a little coolant to the reservoir with every oil change, but it wasn't enough to notice the water in the oil. Now, with nearly 80,000 miles the leak is bad enough that the coolant light recently came on.
Van had the same problem with the intake manifold gasket that is apparently extremely common with this vehicle. It cost me about $800 to have the repair done at a local mechanic. It would have cost more than $1200 to have it done at the dealer. Shame on gm for not issuing a full recall for this obvious defect!
2000 pontiac montana 3.4 liter numerous coolant leaks at intake area at about 60,000 miles. Also coolant cooler allowed oil to get in to the coolant system. I retorqued intake and aleviated problem for about 10,000 miles and then came back. Ended up having dealer replace intake gaskets and they informed me that gm had redesigned the gaskets because of an epidemic of this exact problem. The dealer designated 1 mechanic to specialize with this defect and I talked to the mechanic and he ingformed me that he had done this so much that he could do the wokk in about 3 hrs versus the original 6 to 7 hours it took him the first time his quote "you do it as much as I have and you get very efficient". Gm should have recalled and made good on the repair. In the last 20 years I have bought 6 new gm vehicles and I am very dissappointed that the dealer/corporate would not make good on the repair. It cost me $550.00 for dealer repair. I want to be reimbersed for the repair cost for this is a known defect that gm chose to ignore other that making sure that the newer montanas (3.4l) have the new designed gaskets.
New march 2000. Van always receives regular maintenance. The following is a history of repairs: 4/00 windshield wipers would not return to closed position - dealer fixed. 12/03 (37,179 mi) tps sensor breaking down causing idle to surge - dealer replaced throttle position sensor, completed reprogram ($255.14) 12/03 (37,182 mi) air bag light coming on - dealer replaced right front seat belt buckle under warranty (labor $134.51). 12/27/03 (37,555 mi) was in collision (other vehicle pulled out in front of me as I was coming down small overpass, he was cited). My van sustained $4,500 in front end damages, his car was totaled. My air bags did not deploy. No one injured. 5/04 (40,983 mi) rear hatch would not stay up - dealer replaced both hatch props ($258.73) 7/04 (43,437 mi) van was "shifting" hard, would not pick up speed correctly. Dealer replaced pressure control solenoid, flushed transmission and replaced front brake pads and machined rotors ($986.48). 12/04 (48,284 mi) van would not start on several occasions. Known independent repair shop replaced battery, checked oil leak. ($114.90). 4/05 (51,646 mi) low coolant light /check engine light coming on. Same independent repair shop replaced intake gaskets, thermostat, spark plugs and filter, and oil pump shaft 0-ring. Corrected air bag light ($791.03) 6/05 purchased new tires and were told needed all new tie rods. We went on vacation july 9, 2005 (ohio to virginia and back). Concerned that the van shook terribly when applying the brakes on long downgrades through wv and va. We were towing nothing. The very next day, after returning home, the van would not start consistently. 7/05 (56,533 mi) told that the computer crashed. Same independent repair shop replaced ECM, crank sensor, ign module and machined front rotors which if you remember were just done in july of 2004 ($982.02). After researching the track record of pontiac montana, have found that many consumers having the same problems.
Fuel gauge reads full when empty and empty when under 3/4 of a tank. Message center alarms telling me that I am out of fuel but when I stop at the gas station it will only hold no more than five dallors. Also I have had to have the break lights replaced sevrel times. The rear motorized window on the driver side does not always shut when pressing the button. And engine is quick to overheat. Also the passanger sliding door does not always latch properly, lock and unlock when buttons pressed. The sad thing about it is I have only had the van for just under a year. The van is only five years old and I am already having this kind of problems out of it. Needless to say I will never own another pontiac (gm).
While driving the check engine light came on. Consumer pulled off the road , called the mechanic, who told them to check the water level, which was fine , the antifreeze level was empty. Consumer refilled the antifreeze and drove to the dealership, who indicated that the intake manifold gasket had gone out, and needed to be replaced. This was a common problem with this vehicle.
Dexcool antifreeze leaking from engine. Took vehicle to my mechanic and was told it had a faulting intake gasket. Replaced all gaskets at a cost of almost $800. Was told gm redesigned gasket but did not place a recall on the part. Old parts are not available.
1.while getting my tires rotated, carx noticed my coolant was leaking. 2. Antifreeze was getting into the engine, and if not fixed would damage it. 2. Took car to pontiac dealer. Bill to fix was $650. Replaced the lower intake gasket.
The door comes unlatched from the pontiac montana mini vans w/o power slider also. Subsequently my van door passanger side came open slamming off half on the road and then remained attached to the top but the track wheel snapped off, making it inpossible to put on with out tools and the muscles to even lift it.
Low coolant light came on. Could smell burning coolant turns out the intake manifold gasket was cracked causing coolant to leak. Paid $900 in repairs. Contacted general motors and the will not do anything at this time. Seems to be a common problem with this model car. This happened at 71,000 miles.
I won a 2000 pontiac montana and I noticed over the past year that I was loosing a little anti-freeze over time. The rate increased over the past month until the "engine overheated light" came on. When taken to the repair shop, they told me that the intake manifold gasket was leaking and I was loosing anti-freeze through the gasket. They also said this was a common problem for gm 3.1 and 3.4 liter engines.
I have a 2000 pontiac montana and have had a coolant leak problem. My van has only 66k miles on it and has been in 2 times for coolant leaks. On 11/26/04 I had a coolant leak and had to have lower manifold gasket replaced. On 12/2/04, leaking coolant into the interior and now have bad heater core. I have been researching and there are many other problems of the same exact cause. I believe this is a manufacturer defect and should be compensated back what I paid out.
My 2000 pontiac montana with a 3.4 litre engine was leaking fluid on the garage floor. I took it to a local mechanic and the technician said that the intake gasket was the cause of the problem. He replace the intake gasket and bolts. The total cost was $674.94. The technician also mentioned that this is a common problem with gm v-6 engines.
Noticed that coolant had to be added even though no aparent leak or overheating on my 2000 pontiac montana. I was told by the dealer it was an intake manifold gasket leak and would cost $970 to fix. I found that this is a common problem on this model engine either due to the dex cool coolant or the gasket. If this sin't fixed, it could lead to being stranded or stuck in a dangerous loacation.
At 26,000 miles my van started leaking coolant, alot of it. I took it to the dealership nearby and the mechanic took a quick look and said it would need the engine pulled and all the rubber rings or gaskets in the engine replaced because they were leaking and it was a common problem with this vehicle. He said they need to be replaced with better quality ones because that was the reason they were leaking, that they broked down quickly because they were inferior. And all this would cost me around $1,000. Updated 07/24/2012 *js information redacted pursuant to the freedom of information act (foia), 5 u.s.c. 552(b)(6)
Lower intake gasket failed. Mdealership repaired at my cost shortly after, the cam shaft broke. I will not pay to fix.
Intake manifold gasket leaking coolant. Replacement of intake manifold gasket, cooling system flush, oil and filter change.
Head gasket failure, which alot of other people with 2000 pontiac montanas have complained about also...gm is doing nothing about this and they know about the problem.
Was having a loud whooping sound took to dealership to have checked out no one could figure out the sound so they check A/C and said the A/C compressor was going out and replaced it since then I have had the van in the shop cause A/C will not work 3 times since I have noticed that there was a nother complaint about a loud sound no one could figure out to and my loud sound is still happening.
Upper and lower manifold gasket coolant leaks. (dealer claims that they are doing 10 a week on this vehicle).
Consumer complained about intake manifold gasket which was causing a coolant leak into the engine. Intake manifold gasket was replaced by dealer. *ak the consumer feels this part should not have failed at 48,000 miles.
Recently a number of gm car/vans have experienced problems with the 3100 engine. A great number of them have a "low coolant" indication with the result being a new intake manifold with a cost of $700 to $1000. Is there a problem with this engine.
I have a 2000 pontiac montana with a 3.4 liter engine. I had the intake manifold gasket replaced in january of 2003 because the coolant was leaking out. It cost about $600 to do this. I recently changed the oil on february 29, 2004 and noticed coolant in the oil again. I am now working with the mechanic again to fix the problem. Apparently there is a quality control problem at gm regarding their manifold gaskets. I know other people with the same problem. A friend of mine owns a 2003 grand am with a 3.4 liter and they had to have their intake manifold gasket replaced twice. My brothers rich and steve also owned gm trucks that needed the intake gaskets replaced.
The intake manifold gasket had to be replaced on my 2000 pontiac montana at 109,000 miles. My daughter has a 2001 pontiac montana with about 47,000 miles and she needs to replace the intake manifold gasket also. Sounds like the gasket may have been substandard.
Gas gauge fluctuated and antifreeze leaking. Diagnosed as leaking intake manifold gasket and wiring harness for fuel assembly was corroded due to exposure to moisture - repair bill $1400.
I purchased the vehicle at 72,000kms (45,000) miles and shortly afterward noticed that coolant needed to be topped up occasionally over the subsequent six month period. There was no evidence of coolant leaking into the crankcase, but there was a pool of coolant collecting externally under the intake manifold. After some on-line investigating, I contacted my local dealer, inquiring as to whether this was a common problem. I was told that it was likely the intake gaskets and sometimes the gaskets "get old and dry up" but that it was not overly common. They quoted me apx $800 to repair. ($350 for the intake gaskets and "numerous" other gaskets that would require replacement plus labour). I politely commented that I was baffled how a 3 year old plastic gasket could be classified as "old and dried up". I subsequently had an independent mechanic replace the gaskets using the newly issued version of the gaskets for a total of apx $450. (he had coincidentally run into the same problem a couple of weeks prior on another gm v-6 product, but apparently the coolant leakage was internal and too late to salvage the engine). Mileage at the time of repair on my vehicle was apx 86,000 kms (54,000 miles). He confirmed that upon removal the only evidence was external leakage. I have another 10,000kms on the vehicle since repair and no leakage is apparent at this point.
