This actually happened to me yesterday for the first time. The steering felt locked on like cars with self-driving enabled. Very stiff to move and seemed to push back when I got off-center. It was 100% a software thing. I could feel it pushing back, not like power steering failure at all. There was active resistance. The car was still driving straight, just stiff.
I loved it. Drove around for an hour with a proper weighted wheel. Wish BMW made cars with that heavyweight steering feel again. This needs to be a selectable option in sport mode.
Parked and shut off the car. When I came back hours later it was normal again.
