On 07/16/2026, I was driving my 2023 Tesla Model Y when the vehicle suddenly began swerving rapidly left and right across multiple lanes without my intended steering input. The vehicle became difficult to control, and despite my attempt to correct the direction, it continued to move unpredictably and resulted in a collision. There were no prior warnings or indications of a steering or control issue before the incident. After the collision, I reviewed the Tesla USB drive and found that Dashcam and Sentry Mode recordings from immediately before and during the incident were not available; only recordings after the incident were present. I am concerned that a possible steering, electronic control, or software malfunction may have contributed to the loss of vehicle control.
