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.

Coolant leak around thermoplastic intake manifold. This coolant leak developed around 42000 mi and is a design flaw that the dealer admits. Also dex-cool is falsley advertised that it can go 150,000 or 5 years. Most consumers aren't aware that it turns acidic and destroys gaskets and other cooling system components. I feel the coolant leak and associated dex-cool problems demonstrates GM failure to correct a known defect. Unfortunatley the consumer pays dearly right as warranty expires. GM should replace thermoplastic intake manifold with something more durable and heat resistant.

When the heating system was turned on there was a strong anti freeze odor within the cabin. The odor caused a burning irritation in the eyes and nose. This was caused by the heater core leaking anti freeze into the cabin of the vehicle onto the driver's side floor.

  • Automatic transmission

At 47000 miles and only 9000 of these miles were put on by me. I just bought it 5 months ago. The lower intake gasket had to be replaced. Costing me $813.37 this is a common problem in the 3800 engines. Mine is the 3400 and I'm told by the repair person that it is common in these to. Why won't GM help me pay this repair work.

Any time the vehicle is turned on message center light indicates that the coolant level is low. Consumer checked the coolant levels several times to find them up to par. Vehicle had been taken to several mechanics who could not determine why the message center light would not go off. Manufacturer and the dealer have been notified.
