NHTSA Complaint #11606349 — 2024 BMW X1

The auto start software will turn the engine off when the car is still rolling. I can be rolling 2-4 MPH and the engine will just turn off. There’s a huge delay after the engine restarts for power to continue. There is no way to permanently turn off this feature. If you are making a left turn across traffic you can be in a situation where the car will allow you to roll into oncoming traffic with the engine off. And as you press the gas nothing happens. It happens randomly so there’s no way to “learn” how the car behaves and anticipate it. In addition when the engine power does resume, it jolts forward and is sudden. The dealer has said there is nothing they can do as it’s BMW USA software. There’s no warning and no way to know that the engine is off. The software will only tell you when the car is at a full stop. Even then, the only indication is the small “ready” words. This is very easily reproducible by driving through several stop signs in personal mode.
