Wife was driving home from Calgary when the vehicle suddenly made a loud bang, lights and horn start flashing and it died. Onstar immediately called and said to exit the vehicle as soon as possible to avoid a potential explosion.

Fire department looked over the car and said it looked okay and it was towed to my dealership. Initial diagnostic is showing the battery internally arc'd and that they have never seen this before so GM North America is now involved. 2024 with 19000km
