2011 BMW X3 drivetrain & axles problems

I pulled my car into my flat garage, placed it in park, turned it off and went into the house. 1 hour later it had rolled out into the yard. It was off and in park. It was towed and evaluated by a BMW "expert" who determined there was nothing wrong. They said the car could not have been left in neutral and could not have been left on and then gone off. They had no explanation for the failure to hold the park position and that it was safe to drive!!! My insurance covered the $3200 damage and car rental.

The contact owns a 2011 BMW X3. The contact stated while driving 10 MPH, the vehicle stalled. The contact stated that the vehicle failed to shift into neutral. There were no warning lights illuminated. The contact stated that the failure was linked to NHTSA Campaign Number: 23V707000 (Engine and Engine Cooling). The vehicle was taken to an independent mechanic who replaced the engine and redesigned the timing gear assembly. The local dealer was contacted and confirmed the parts were not yet available.
