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.

I also had the problem with the lower intake valve gasket but instead of one time of paying 5-700.00 to have it fixed I have had to have it done twice and my van only has 84,000 miles on it I know that there are always problems but I think that if this many people have had the same problem that they should do something about it.

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.

Assistance (tis request tis03-007115 dgd closed). Vehicle had urine odor coming through the vent in the interior of the vehicle. The service dept. Stated the coolant went bad and leaked into the ventilation system. They removed the A/C, heat unit, vent and ducts but the smell returned. Consumer returned the vehicle four days later. Consumer was informed that the problem they've experienced is a nationwide defect with that vehicle.

Coolant is leaking into the ventilation system causing a "urine" smell to enter the passenger cabin. Passengers are coughing and have constant headaches. Dealer will replace the ventilation system.
