I was driving at about 65 mph on a highway uphill, engine completely stalled, no power, got a message "drive-train malfunction, no maximum output, drive moderately". I was surrounded by cars/semi trucks, very dangerous situation. Managed to pull over on the should. Could not restart car, got a message "automatic start/stop deactivated: Engine will not start automatically. Press the start/stop button to start the engine." About 30 mins after engine stalled, I finally restarted the car. Continued to drive on the highway for about 10 miles @ 60-65 mph. At a local street, as I slowed down to approach a traffic light, engine stalled again, no power, car stopped in the middle of road, got the two same messages, could not start car. About 30 mins after engine stalled, I finally started the car.

The contact owns a 2012 BMW 550ix equipped with Goodyear Eagle P245/40/R19. The contact stated that while driving 45 mph an alert on his dashboard illuminated instructing him that the vehicle should not be driven more than 50 miles as the tire was going flat. Thirty miles later the vehicle was stopped and the front driver side tire had developed a bubble on the sidewall, which caused the tire to shred. The vehicle dealer was notified but offered no assistance. The manufacturer of the vehicle was notified but offered no assistance. The tires had not been replaced. Updated 12/14/12 the consumer replaced all four tires with Michelin tires. The consumer stated two of the original four tires developed bubbles on the sidewall. On two occasions, the drive train malfunctioned. The video screen flashed a message instructing the consumer to return the vehicle to the dealer. In the process, the vehicle lost a considerable amount of power output and shook violently when driven over 30 mph. Updated 07/09/13
