The 2011 vehicle with less than 65,000 miles normal runs at highway speed in a range of 2k rpms. a warning regarding the transmission immediately caused the car to rev up to 5k rpm (very high for a diesel engine sedan) and the speed reduces 30-40mph while driving. it is incredibly scary and dangerous. assumed this was a one-off. pulled to the shoulder, turned off the car and it ran fine. took it to bmw for inspection and they said they could not diagnose the problem but would replace the transmission and charge me more than half the value of the car. the issue has since repeated and is very dangerous to all on the road.
Car stalled multiple times while driving. each time it was a sudden death while driving. every time got lucky that i was not followed by a truck and no one hit me from behind. dealer replaced engine earlier, diesel pump and now dealer said reported all injectors failed. history: 1/5/17 - car stalled while in motion on city street - speed 30/hr 3/3/17 - car stalled again while in motion on highway - 50/hr 5/20/17 - check engine light - no stalling 5/31/17 - car stalled - on city street at red light. 2/13/18 - car stalled while driving - speed 50/hr 3/1/18 - car stalled - speed 15/hr - after stopping and starting at red light in city street. downhill. no break . started rolling down. used hand brake. 3/7/18 - car stalled while driving in snow city street - speed 25 /hr repairs: 5/23/17 - egr cooler , injectors replaced 5/31 - 6/18 - car was at dealer and engine, intake manifold replaced. 2/13/18 - diesel pump replaced. 3/7/18 - car is with dealer - reports multiple injector failure
