On June 7, 2026, I was driving westbound on I-290 in the leftmost lane in a 2024 Tesla Model Y. I recall FSD (Supervised) was engaged and making a lane change into the left lane. Instead of settling in the lane, the vehicle continued left and struck the divider/median. I braked. The vehicle then bounced back and moved right toward a large truck and collided. I did not receive a takeover warning before the event. The front bumper came off and the vehicle became inoperable. A fire truck traveling behind me blocked traffic after the crash. Tesla event data records a Crash Algorithm Wake-Up at about 9:49 a.m. Central and includes speed, steering, braking, acceleration, ABS, lane-assist, and cruise-control signals. I reported the safety concern to Tesla and asked for review of the FSD/software issue and data, but I have not received written findings. I do not have an expert determination that FSD caused the crash. I am asking NHTSA to review the incident and data for a possible driver-assistance, steering, or lane-control safety defect.
