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.
