“I almost had a terrible accident in my 2 week old 2018 M5 on the 1-95 highway on the night of may 25, 2018 at about 9:45pm. Without warning, at about 65mph, the car jerked for about 3seconds , kicked out of drive into neutral and started decelerating. I was in the middle lane surrounded by speeding vehicles. I managed to guide it to the shoulder and turned off the ignition for 2minutes, after which I re-started the car and was able to engage drive. …”
