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 have a 2001 Pontiac Bonneville SSEI. I have had this car in and out of the shop numerous times for the "check stability system" warning and a "clunking" noise in the left front area. It makes noise primarily in a turn or going over a bump. I have had the front left wheel bearing/assembly replaced as well. The last mechanic was puzzled and frustrated at the fact that he cannot figure our what is making the noise. I believe that this is a defect and GM should issue a recall and fix the problem for the consumer. GM wonders why their sales a slacking....maybe they should take better care of their customers. Makes me think I should have bought a Toyota.....

Car displays "service suspension system" warning after abrubtly locking the right wheel at highway speeds. This has pushed my vehicle to into another lane towards oncoming traffic.
