Example complaints
Electrical system: “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. …”
NHTSA complaint #11010249, filed 2017-07, 2,000 milesAir bags: “In march 2017, I was driving southbound on the right lane of a parkway, when a vehicle that was two cars behind me, accelerates out to the middle lane, he loses control of his vehicle, his car goes to the left lane then turns around almost perpendicular to me, and collides into my vehicle pushing me off onto the embankment, continuing to collide into my car multiple times, before his car goes up into the air and lands on the hood, backwards. I thought I was going to die, and the multiple collisions against my vehicle seemed endless. …”
