The contact rented a 2025 Chevrolet Trax. The contact stated that, while her husband was driving at 25 MPH on a decline and attempting to slow the vehicle upon approaching a curve in the road, the brake pedal depressed all the way to the floorboard but failed to bring the vehicle to a complete stop. As a result, the driver briefly lost control of the vehicle, only coming to a complete stop after colliding with the vehicle ahead. The air bags did not deploy. No warning lights were illuminated. The vehicle was not taken to the dealer or an independent mechanic but instead returned to the rental company. The contact was unaware whether the vehicle was repaired. A police report was filed, and no injuries were reported. The manufacturer was not notified of the failure. The failure mileage was 14,700.
