NHTSA complaint #11736095, filed 2026-05, 17,000 miles

Forward collision avoidance: “Several times, the car's panic braking has randomly slammed the brakes and tightened the seat belt. After the first few times, I took it to Mercedes and they re-uploaded software which was hard for them for some reason. It fixed the problem. Luckily, I had always been on small streets. But today, the panic braking happened again, only this time, I was on a major road (4 lanes at 35 mph) and, with nothing around me, no cars in front of me, the panic braking and seatbelt tightening happened so violently that I was thrust forward with enough force to hurt my hip. Nothing severe no doctors needed. …”
