We purchased a 2008 Chevrolet Trailblazer in September 2008. The day we drove it home the entire electrical system shut down. The lights, locks, blinkers, and all gauges were not working. The vehicle was taken back to the Chevrolet dealer and the onstar module was replaced. A few months later the electrical system failed again, this has happened 3 more times since purchasing the vehicle 3 years ago. The vehicle has also had the check engine and stabilitrack lights turn on and off numerous times...sometimes for a day or two, sometimes for a week. The vehicle has been in the shop more than 13 times in 3 years for electrical related problems, several electrical modules have been replaced. My grandmother has the same vehicle and has had the same type of problems with the electrical system.

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.
