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.

While traveling on the interstate highway 295 in NJ my vehicle stalled. The stalled and almost caused a near fatal accident with a semi. The vehicle after 20 minutes and numerous attempts the vehicle started back up and I decided to try and make it home by taking back roads away from the interstate. The vehicle stalled 4 more times before I could get it home. I was visibly shaken upset and scared out of my mind.

- the contact states that the engine coolant is leaking at the upper intake manifold. The contact states that there was a safety campaign regarding the same issue he has with his vehicle and that he wasn't aware about the issue until he was doing research online. By the time the contact found out about the safety campaign the time for the campaign had expired. The contact is concerned because when he took it to the dealership and they stated that the problem with his vehicle is a common problem that has been happening with various 2002 Pontiac Bonneville.

Car was brought into otto Oldsmobile dealership with 64K for a warranty replacement of a waterpump and for a squealing noise. Was told the intake manifold was leaking and the estimated repair was 600, with the serpentine belt and the waterpump labor total repair was 1100. Car was driven twice after repair, less than 200 miles when squealing returned and engine seized from coolant entering cylinder number four as a result of the manifold leak. Car sat in dealership for three months while we haggled with them and GM for replacement costs. GM denies responsibility and car had an engine installed from a junkyard at a total cost of 350. Car is currently still squealing.
