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.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety.

2002 Pontiac Montana Owner Comments

problem #3

Montana 6-cyl

  • Automatic transmission
  • 70,000 miles


The contact owns a 2002 Pontiac Montana. The contact stated that the head gasket and the intake gasket had corroded from a cooling leak. She also experienced overheating and the only coolant that the dealer is telling her to use is dex cool. The contact stated that this type of coolant has been known to cause failures and that there should be some other type of coolant to use. She stated that the power door on the passenger side has signs of corrosion, the fuel gauge is erratic and prevents her from knowing the amount of fuel in the vehicle, the driver side front tire hub is loose, the overhead console for the temperature and compass has failed, and the air conditioning has a hole in the hose. According to the manufacturer, since the contact changed her own oil, that is the reason she is experiencing so many failures. Therefore, the manufacturer stated that they are not liable. The VIN is unknown. The current and failure mileages were 70,000.

Engine stopped without warning while driving a low speed on three seperate times. First time was in the middle of a right turn after traffic light change to green. The same thing happend a second time as I pull into a gas station. This third time happend as I was looking for parking space in the parking lot. In all three time, the engine stopped without warning and power steering was lost. I was able to stop the car and after restart the engine after shift to park. The dealer could not find anything wrong with the car after each incident as there are no fault code.
