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.

My service air bag light stays on. I had it checked out. The passenger seat sensor is faulty or has faulty wiring. It's a newer vehicle, I currently have 72,000 miles on it. And is a safety concern for anybody especially my kids who rides in my passenger seat. The sensor will not acknowledge any weight on the seat and will not activate if I were to get into an accident. I called up a while back and put in a complaint. Somebody called me back but never answered my phone or messages I had left. I've researched this issue and have noticed there's a lot of people with the same problem. I expect Chevy to stand by their product and address this issue. Thank you

I was driving home from work and the car started acting like it was uneven. I got to where I could pull over and found a balloon growing out of the side of my tire. The car is not that old and the tires in my past Impala's have lasted much longer. I am not happy with this. I had to call someone to help me so that it didn't explode and cause more damage.
