Engine Shut Off Without Warning problem #1

I was driving appx 40mph while on a local road slightly uphill, engine shut off without warning, lost power steering and brake assist. Luckily no cars around me so I was able to barely roll over to the roadside. Car would not start again, was towed to dealership. Replaced ecu for a total cost of $2k.

Engine Failure problem #2

Intermittent engine shut-down. Engine shuts off while vehicle is in motion at any speed. "engine failsafe" warning light comes on. Vehicle must be stopped, key turned off and re-started. This is a serious safety issue that BMW is aware of and has issued a related TSB. $2000 plus repair bill for a new "engine wiring harness". BMW should be recalling these vehicles.
