2016: “My car is actually a 2017 Bmw 340I but the system did not allow me to choose that car. I had the auto-start/stop feature engaged and the car stalled once I came to a complete stop. I was driving on a street at the time. I had to restart the engine but it wouldn't start completely off. I disabled the feature and it stopped doing this. Later on july 5th, the car simply stopped starting all together. At this time I was parking in my parking garage at home and when I turned the car off I tried starting it back and it no longer worked. …”
