2026 TESLA MODEL Y — FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL

On the day of the incident, I drove my vehicle into the charging station and activated the Tesla FSD autonomous driving and automatic parking functions. During the automatic parking attempt by the vehicle, the system exhibited the following severe loss of control behaviors: 1. The vehicle automatically collided with the vehicle in front without any human operation. 2. It paused for about 1 second after the collision. 3. Then, the vehicle suddenly accelerated in reverse at high speed, again without any driver operation. 4. It directly hit another Tesla that was charging behind my vehicle. The entire process is fully executed automatically by the vehicle system. I cannot intervene or stop the system through the steering wheel or brakes. II. Severe Security Risks When the accident happened, my friend was sitting in the passenger seat. If the vehicle had moved a few more inches, it could have caused serious injury or even a life-threatening situation. This system failure is a combination of Sudden Unintended Acceleration (SUA) and the loss of control in autonomous driving decision-making, posing a significant systemic risk to public traffic safety. I immediately contacted Tesla and sent a complaint letter to the North Carolina Consumer Center. They accepted my complaint and sent an email to Tesla, but it has been over twenty days and I have not received a response from Tesla.
