We have been driving the Bolt for almost 2 weeks now and then suddenly since yesterday every time after we start the car, the OnStar voice would say "This vehicle is in Demonstration Mode, provided by OnStar 4G network...". I contacted OnStar twice about how to turn it off, both times were told that the dealer needs to do something about it, not OnStar. I contacted Dealer, was told to first put car in D, turn on the hazard lights, press and hold the Power button for 90 seconds and the car should come out of the Demon mode. But we tried twice and it didn't work. The dealer told me that they would continue to investigate this and call me back when they find a solution. Maybe someone from this forum knows better?
