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 Bonneville Owner Comments

problem #2

Apr 282008


  • 92,000 miles


The contact owns a 2002 Pontiac Bonneville. While driving downhill at various speeds, oil leaks onto the valve cover manifold. Smoke appears under the hood and the contact smells burning oil. When the hood is lifted, he can see the oil on the valve cover manifold. The contact must check the oil level monthly. His neighbor informed him that there may be a recall related to the failure. The contact took the vehicle back to colandrea Pontiac in New York and they stated that his vehicle was not under a recall, and will cost approximately $300- $500 to repair. The failure mileage was 92,000 and current mileage was 93,895.
