2015 BMW 328I Vehicle speed control Problems

“At random the car will display “Drivetrain Malfunction” which causes the car to shift into neutral and begins to slow down until it doesn’t move anymore. There is no check engine light or any other indicator of what might be the problem. The message just pops out of no where. It’s happen in the freeway making me scare to cause an accident because it so random. I’ve had to quickly turn my hazards and beginning switching lanes to avoid any accidents.”

“I pulled into my long narrow driveway (about 100 feet) slowly at about 3 MPH. I let the car go by its momentum and lightly pressed on the brake so it could come to a complete stop. When the car approximately about 7 feet from the front of the garage, it accelerated suddenly and smashed through the front door and part of the garage. I put more pressure on the brake, but it kept going and hit the back wall before the engine shut off. The airbags did not go off. I reported the incident to the police and my insurance, and the insurance declared the car was total loss and they towed it away.”
