My father was driving home from golf. He was driving for about 5 minutes. He was at a red light and smoke started coming out of the car. He turned car off, then on. Smoke started getting worse. He put on the emergency blinkers, got on the sidewalk, and looked underneath the car. Within a few minutes the car blew up. There were no warning lights and the car was driving normally. Car was brand new and was about 1 year old. 2022 GLC.
