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.

I recently had to replace my intake manifold for my car in July, and just today I had to take my car to the mechanic because he said that the rear intake manifold was cracked and had to be replaced. He stated that Grand Prix were built with plastic intake manifolds.

Prior to the fire, she received an important safety notice stating that a recall was about to be issued to prevent the vehicle from catching fire in the engine compartment. The dealer did not have the parts for the repair and the manufacturer would not assist.

Recurring burning oil smell and oil leak on my 2002 Pontiac gtp Grand Prix. @ different dealers have had the vehicle to fix it multiple time and at a cost of more then $1600 dollars. Only the have the repair fall under a recall after which they wont refund my money. Additionally the car still have a oil leak and burning oil smell. These are the symptoms for the engine fires that consumers are experiencing with this engine. I cant even sell the car, no one wants it due to the nature of the problem. I'm reading dozens of similar situations even some homes being damaged from fire resulting from the engine fire after you turn the car off.

Grand Prix 6-cyl

  • Automatic transmission

2002 Grand Prix GT leaks coolant at upper intake manifold. Vehicle only has 31,000 miles. Upper intake manifold gasket failed thus allowing coolant to leak inside and on top of the engine. The upper intake manifold gasket had to be replaced and the engine cooling system flushed for any contaminants. GM technician indicated that the gasket was replaced with a newly designed gasket. This is a known problem by General Motors (NHTSA 10006144) and their solution in 2003 was to add coolant pellets and to change the nuts on throttle body. In my opinion, if there was damage to the gasket before the recall, the coolants pellets would have only prolonged the time it took for the gasket to totally fail. Thus forcing the customer to pay to fix a known defect since the car is was no longer under the manufacturer's warranty.
