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.

  • 6,000 miles


The contact owns a 2008 Chevrolet Trailblazer. The contact stated the voltage regulator was corroded and caused the brake light unit on the rear driver's side to also corrode. The vehicle was taken to an authorized dealer where the sockets were replaced but the failure recurred. The vehicle was taken to a second dealer where the alternator was replaced. The failure continued. The vehicle was then taken to a third dealer where it was awaiting repairs. The manufacturer was made aware of the failure when the contact notified them to file a complaint. The failure mileage was 6,000 and the current mileage was 50,000.

I was driving down a state highway with my cruise control set at 57 mph and all of the sudden all of the lights came on in the console. My on star did not work, nor did the radio or anything electrical in my vehicle. My vehicle was still running, but none of the gauges, lights, windows, etc. Were working. I pulled to the side of the road and then drove it to the dealership. The dealership kept the vehicle for 3 weeks and were not able to diagnose nor fix the problem. All of the sudden 3 weeks later they got into the vehicle and the problem had resolved itself.

While entering a gas station the vehicle in front of me slammed on the brakes. This was done because the GM at the pump had it's backup lights on and wasn't even backing up. What's really disturbing is the fact people will start ta ignore these in dark or rainy parking lots and potentially get run over. Shouldn't backup lights only be used for backing up? this looks like a problem with the whole vehicle lineup.
