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.

problem #1

I have a Chevy Impala, 2011, and a month or so after buying it the "service stabilitrak" light came on. Before I could get it into a shop, it went off. It came on again yesterday and my engine power all but shut down, I was trying to get through an intersection and thought I wouldn't make it. After researching, I see that Chevy has had numerous issues with this. Why are they not repairing the problem? this is a huge safety issue for drivers.
