NHTSA Complaint #11682605 — 2023 TESLA MODEL Y

While driving a Tesla Model Y on a freeway in Arkansas, the vehicle was operating in Autopilot mode (Tesla's driver-assistance system). During a highway merge, the vehicle followed a state trooper's car too closely and failed to slow down appropriately. The trooper had to apply his brakes to avoid a collision. After stopping the vehicle, the trooper issued a written warning, explicitly attributing the issue to equipment failure and advising immediate correction. This issue appears to involve a failure of the adaptive cruise control and forward collision detection system while Autopilot was engaged. No collision occurred, but the situation posed a clear safety risk to both the trooper and my vehicle. This was not the first issue with the vehicle's automation. In a previous incident (November 2024), the vehicle exceeded the posted speed limit while on Autopilot, resulting in a traffic citation. Tesla has been notified, and a service request is open. Diagnostic review is pending. There were no warning lights or alerts from the vehicle before the incident. The vehicle remains available for further inspection if required.
