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 car threw a drive train malfunction code which happens weekly on these engines and the car jumped a lane as it misfired and went into limp driving mode. If there was cars next to me there would have been a crash. Since then BMW has issued a customer campaign on the N63 engine effecting thoughts of cars. They are changing tons of parts from injectors to fuel rails. It should be a full blown recall and the NHTSA should get involved on this. My car has been in the shop since 12/23 and still has not been repaired correctly. I have a feeling you are going to be getting thousands of these complaints against BMW. They need to be held accountable for these failures.
