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 purchased a 2003 Pontiac Grand Prix SE with a V-6 and I get water coming in the passenger side every time it rains. Also the transmission shifts hard occasionally when going from first to second gear. I was told to fix the leak would be around $300 and the transmission problem.... I may as well buy another car for that price....
