Your 2021 Prius unexpectedly accelerated on its own while driving at 35-45 mph, and the brakes didn't respond immediately to stop the vehicle. You had to swerve around other cars and ended up in a ravine; your husband pressed the Start/Stop button to shut off the engine and bring the car to a halt. The dealer was unable to identify what caused the acceleration problem, and Toyota was notified of the issue. The problem may involve the electronic throttle control system or brake system sensors that need diagnostic testing and potential replacement.

NHTSA #: 11615271
