Vehcile is losing coolant discovered a bad iontake gasket. Repairs totalled $800 by local delaership. Rampant problem with this engine
Pontiac montana presented with a low coolant light,, found to have a faulty intake gasket, (repaired for approx $700.) when asked about rate of occurrence, gm service manager stated "it happens a lot more often than gm wants to admit in the 3.4l and 3.8l engines".
Failure of lower intake manifold gasket on my 1999 pontiac montana. Internet search provided evidence that thousands of these are failing and there has been no recall notice to date.
I own a 1999 pontiac montana and at 54,000 miles began experiencing loss of oil and coolant. I took to a repair shop and was told that my intake manifold upper and lower gaskets need to be replaced, as well as my thermostat and gasket. Quote $900 for repairs.
1999 pontiac montana- coolant in oil- leaking intake mainifold gasket and bad water pump. 75,000 miles at time of incident.
My wife & I own a 1999 pontiac montana. In september with 53,000 miles we noticed that the low coolant light came on. We added coolant and about 2 weeks later the light came on again. I then contacted my personal mechanic (since the vehicle was no longer under warranty). He told me that the intake manifold was bad and that this was a very common problem with this type of engine. He also told me that gm dealers told him that it was a result of the intake manifold being made of plastic and that the dexcool was eating up the gaskets and the plastic manifolds. The cost of the repair on the intake portion of the engine was $392.57. He also told us that as a result of this, coolant spilled into our engine oil. This means that we have a good chance of engine failure in the near future and would have to replace the engine. Replacing the engine would cost $2000 -$2500. We did contact the dealer where we bought the vehicle and posted a complaint. They told us to contact pontiac. We did call the pontiac customer service center in michigan an filed a complaint over the phone. They claimed that they have never heard of such a thing. Please respond. Thanks
Consumer states that while driving and without warning the intake manifold crack causing coolant fluid to leak onto the engine. Dealer notified. Ts
Lower intake manifold gasket leak causing coolant/oil mix internally on a vehicle with only 41k. Caught before christmas 900mi trip. Would have likely caused engine to seize if not caught before trip. Oil was creamy white.
Consumer states speedometer stopped working twice. The instrument cluster had to be replaced both times.
The manufacturer does not have parts available for a 1999 production vehicle. Been told by my selling dealer that the part is on "national back-order" with no expected date of arrivial. Was also told that the manufacturer stopped making the part due to a supplier failure. Was also told that the dealeraship itself was had six vehicles waiting the same repair. I thought that the manufacturer had to have a supply of parts available for all car for at least ten years past production ending? This is a three year old car.
Camshaft broke while consumer was driving, causing vehicle to stall out. Contacted dealer.
We have been plaged with coolant leakage for some time. Our intake gasket has been pegged as the cause. Why should the consumer be forced to foot the bill for something that in my mind is an assembly or defect problem. Noone should be having to fool with the engine on such a new vehicle. This is above and beyond any wear and tear issue.
Vehicle overheated while driving 30 MPH. The dealer determined that the lower intake gasket need to be replaced. Per dealer 30000 of these parts are on backorder.
I went to the dealer complaining of no heat coming out of heater although the temperature gauge was normal. The service adviser said I probably had a gasket leak, opened the hood, and immediately pointed to the spot where it was leaking. It was not leaking enough to mark the pavement, it would just leak onto the motor and evaporate. Obviousely he had seen this problem before. I took my van to get it fixed and a gasket could not be found in indianapolis. One dealer has 15 vehicles down waiting for gaskets and another has, I believe the number was 60 gasket sets on back-order. Yet gm says that the problem is not theirs to be concerned with. My mechanic said that there is a nationwide back order list for this particular gasket, which goes on the pontiac montana, chevy venture, and oids silhouette. In one weekly paper here in central in, there are 33 montanas and silhouettes, from 1998 to 2001 listed for sale. This is a big problem. Can you help?
Passengers electrical mirror gear was stripped and had to be replaced.
Consumer stated antifreeze was leaking into the motor of vehicle due to the gasket material falling on the intake manifold. Nlm dealer found and replaced leaking intake gaskets.
Intake manifold assembly cracked where pipe is pressure fitted into manifold, causing engine coolant to leak rapidly, coolant light came on after coolant container was over 1/2 empty.
We would like to express our extreme dissatisfaction with this vehicle and with the manufacurer. We purchased this vehicle new 2.5 years ago and have had to return it to the dealership on 17 different occasions to have various problems fixed: transmission replaced with 16,000 miles, airbag problems, cd player problems, intake gasket leaking, tires wearing, numerous problems! We have contacted the manufacturer and was told the first time a year ago that nothing would be done and now all they will offer us is extended warranty! We can't afford to keep taking our vehicle to the dealer and just want out from under this burden, big mistake we made!
I writing to express dissatisfaction 2 major component failures occurred on a vehicle with less than 50,000 miles. The intake leak appears to be a known problem - buyer beware. I can understand disc pad wear, but not major brake system replacement/repair. The mechanic also noted excessive lifter noise; I fear this observation will lead to more major repair work. The dealer has been responsive. My complaint is intended for the manufacturere and other consumers. I will not be a good referral for prospective minivan owners - essentially my entire social base fits the demographic for minivan buyers.
We have occasionally had problems with the transmission shifting hard, whining & banging into gear-this goes away if you turn the vehicle off & then back on . It occurrs at slower speeds not highway speeds & seems to happen only on short trips or longer trips with several stops. Recently there was a coolant leak in the system , which a local shop "repaired" for $67 the first week of october. Almost two weeks later the vehicle began running hot again & we were then told it needed a new head gasket. We had the vehicle back for a week when after getting off the highway & stopping for a red light the vehicle started to stall & the low oil pressure light came on. After parking the car & restarting it -it started making a horrible sound & we had it towed in to the nearest pontiac dealer. There we were told that the head gasket shouldnt have needed to be replaced that those engines almost never leak from the head gasket but apparantly they commonly leak from the intake valves. In addition, they said that the garage that did the head gasket did something wrong which caused a blockage in the engine & prevented oil from getting into the top of the engine. They said there were two bolts that were loose & eventually found to be sheared off & that one of the outer heades-not the cylinder heads - were cracked. I have no way of finding out what actually caused the engine failure. I found no technical service bulletins on the head gaskets or the intake valves. Rif the engine had to heads a ardiastiotnetrstarting ccor.
Purchaused used (6 months old) have now owned auto for 2 years. At 38000 miles transmission starting shifting harsh at times, had to replace transmission. Engine has started acting as if it is going to stall for no apparent reason. Radio has been replaced 3-4 time, due to garbbled display. Most recently however, I had door locks repaired, and was told that the wires to the locks were damaged due to the water intrusion caused by the air conditioning leak into the auto instead of outside the auto.
Consumer was traveling 55mph on highway and went to pass another vehicle, and accelerator pedal was stuck down to the floor. He was able to put vehicle in neutral, pull over to side of road, and shutdown. Dealership was aware of problem. Vehicle was towed to dealership. *ak while having oil changed, consumer requested to have the air filter replaced, in order to replace air filter, the throttle cable clamp was loosened to gain access to the air filter housing, it was not lined back up properly causing the sudden acceleration.
At 28,000 miles, the general tires that came w/the vehicle were completely bald & had to be replaced. They were supposed to be 80,000 mile tires & had been rotated numerous times, the cooling system: while on vacation, the cooling system overheated. Told by dealer out of town that radiator cap loose & was tightened. 3 weeks later low coolant light kept coming on & took to dealer on 8/12/00. Told coolant system dirty & needed to be flushed; $100.00. Also told battery that came w/vehicle was leaking acid which also ruined battery positive cable. Both needed to be replaced. Said out of goodwill would not charge for battery cable but charged $98 for battery. Brakes started to fail @ 11,000 miles, rotors cut @ 28,000 & told rotors not under warranty because not considered safety problem. Rotors still warped & need cutting. Brake light socket was melted to light & was fixed by dealer early on.( dot number: acm3kmi368 tire size: p215-70r15 )
The transmission failed. Yh
The van stalls or hesitates without any kind of warning. This happens while driving or taking off after a stop. The van has stalled four times since october of 1999. Van is at the dealership. Dealer is not able to remedy this probelm. Please provide any further information.
Oil pan has heavy oil residue film which gm claims to be normal due to aluminum casting oil pan design that allows oil to seap through the oil pan. A heavy oil residue on the outside of the oil pan does not seem normal and appears to be a leak. Burning oil can be smelled inside the vehicle while stopped. A file # has been opened by gm customer service to record my complaints. Right hand door powered mirror is loose and loses setting when door shut.
While driving on highway/stopping or pulling off or taking foot off gas pedal, vehicle stalls. Has to drive with both feet in order to keep the rpms up. Contacted the dealer, and vehicle is still at the dealer. But, dealer can't duplicate the problem.
Temperature gauge failed.
Electrical malfunction. Passenger side power sliding door does not close properly, when closing with power switch the door makes 2-3 attempts before it closes. Door has to be manually closed.
