I am a newish 2011 X3 3.5 owner (purchased in July) and today my car died entering an elevated highway ramp. The error said it was a drivetrain issue and the car started to lose power. I pulled over as far as I could (no real shoulder so pretty dangerous) and noticed my car was in nuetral. I put it in park and shut it off, waiting a minute and re-started. No errors showed up, so I drove about 100 feet and the same thing happened. I looked down as it stopped and it was again in nuetral. I powered off, then on, and it just sputtered and died. I had it towed to BMW tonight. Is anyone aware of this as a known issue?
