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 bought the car for my daughter. I wanted a nice reliable car, not sure what I got. The car has stopped on the freeway several times. I have not been with my daughter any of the times. She or her boyfriend will pull over and the car starts right up.Now the check engine light is on. I will take it to my mechanic hopefully it wont cost a ton of money. I have no idea what the problem could be. It could be electrical, How could someone sell another human being something when you know it could cause harm to an innocent person. If you have an older Pontiac that had the same problem please give advice.

My car is very crazy and i buy car like 3 months ago!!! The RPM went crazy and vibrate then engine stopped, wont start and i stop the car on the highway and call my parent to pick me to work. Then we fix it and it stopped again like 10 times! We do not know what happen to engine...engine stopped because of unknown! I think maybe motor broke or computer system broke or not. I don't trust car when i drive to New York from Indiana because engine will stopped when i drive on the toll road.
