May 11, 2026 approx 9:35am. I was in a flat parking area at a gas station waiting for a friend. There were 2 other cars parked near me. No one was in them. Neither were moving. I backed out of my space into a large, empty, open area to turn my car around to have a better view. Because the audi pre-sense chronically malfunctions, I always turn it off before I drive. But I left it on this time because I was only driving about 15 feet in a parking area. I backed out, then stepped on the brake to turn the wheel. While I was AT A FULL STOP, the seatbelt motor started up loudly and grabbed my chest with the seatbelt, slamming me back against the seat. No one was there. No cars were moving. I was at a stop. When the seatbelt let me go, I noticed a red lighted image of some sort on the screen. I believe there was a red star-shaped image and some text indicating a collision. Then the image disappeared. I turned off pre-sense and backed into my parking space. It was painful and frightening - especially as I have osteoporosis. This car has previously slammed the brakes on an empty road while I was driving 45-50 mph. Dealer says there are no codes or errors and I need to clean the sensors. I bought it new. Likewise, the rear cross-traffic, pedestrian detection etc. rarely works and sometimes fires for no reason. If the brakes slam when there's a car behind me, I'll be rear-ended. If the seatbelt slams while I'm on the road, I'll certainly swerve from the discom
