I have a 2021 Bolt EV and yesterday I had my foot lightly on the brake and was moving about 1 mph. I put the gear into park when the car wasn't completely still and heard a grinding noise. I was in reverse going into a parking space. Did I do any damage? I don't see any warning lights and the car seems fine, but I definitely made a driving error, the car should have been completely stopped when I shifted into park.
