Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

2001 Pontiac Montana Owner Comments

problem #6

Sep 122005

Montana 6-cyl

  • Automatic transmission
  • 95,000 miles


At 95,000 miles, my 2001 Pontiac Montana van began to leak water and I took it to a local mechanic. He informed me that the intake manifold gasket was leaking and that it needed to be replaced or that it would damage the engine permanently. In order to verify the problem, I took it to the local Pontiac dealer and the diagnosis was confirmed. Both garages told me that they had repaired the same problem on many of the same engines that were used in Chevrolet, Pontiac and Oldsmobile. The cost of the repair was in excess of $830. If these are inherent problems with these engines, why hasn't GM issued a recall" I repaired the same problem with my 1997 Pontiac Transport Montana twice. When are they going to stand behind their product and repair the flawed design"

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.

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".
