Vehicle has stalled while in operation (at speed) 5 times since owning. All were very dangerous situations for my wife and surrounding drivers. All issues were apparently "fuel system" related. I purchased this vehicle on May 11, 2018 (POC) from Fields BMW South Orlando, FL. The car was most recently brought in for repair for a continued issue on May 3, 2021. Vehicle has never been in a wreck and has roughly 73K miles. •5/31/2018 – Issue with fuel system. Car started shaking and would not start. 2 weeks after purchase. •6/05/2018 – Issue with fuel system.

Wife had to quickly pull the car to the median. Dangerous situation. Car will not switch out of park. Wife is driving, 5 months pregnant. •5/3/2021 – Car stalls while driving.

Being stuck in the middle of an intersection and unable to move a car into neutral (even with police officer) is extremely dangerous. Vehicle was inspected by a BMW TSE for transfer case issue. They say it needs to be replaced. This vehicle is a danger and should not be on the road.
