One problem related to car stall has been reported for the 2015 BMW 328. The most recently reported issues are listed below.
On way home today 7/12/2019 car stalled out. I had very little brakes, steering was hard to turn and car slowed down quick. It started back up but then the passenger side window started going down on its own, and the a/c stopped working, and the drivers side window will not go up, and it keeps getting a warning going on then off then on says something about brake lamp control malfunction. When I got it home I left in driveway for a while when I tried to start it back up I started getting transmission failure warning and something about the engine. Then later the car did start up without the warnings but still has the original problems.
