The contact owns a 2024 Honda Accord Hybrid. The contact stated that while driving at an undisclosed speed into a parking space, the brake pedal was depressed but the vehicle failed to stop. The vehicle unintendedly accelerated and drove over a parking space bump. The contact shifted the transmission into reverse(R) and depressed the accelerator pedal, and then the brake pedal, but the vehicle failed to stop. The contact turned the steering wheel while driving approximately 30-40 MPH to avoid crashing in other vehicles and structures in the parking lot. The vehicle reversed in circles and crashed into the side of a fence before it came to a stop. The air bags did not deploy. The contact suffered back, hip, and leg pain but had not received medical attention immediately. The contact's granddaughter was a passenger inside the vehicle and had no injuries. The contact later sought medical attention from a massage therapist. No Police report was filed. The vehicle was towed to the dealer, who determined that there was 100% acceleration without the brakes activating, and the vehicle was not shifted into park(P).

The contact was informed that a third-party company would evaluate the vehicle and the Event Data Recorder (EDR) to recalibrate the EDR. The manufacturer was made aware of the failure, and a case was filed. The failure mileage was 23,069.
