While operating the vehicle in reverse at a low speed (under 5 mph), the Advanced Driver Assistance System (ADAS) failed to provide any audible or visual alerts regarding a stationary vehicle positioned directly behind my path. The vehicle is equipped with a Rearview Video System and Rear Proximity/Parking Sensors, both of which were active. âDespite a clear line of sight and the secondary vehicle being a standard passenger car, the sensors did not "ping" or trigger an emergency brake/alert, resulting in a rear-end collision. The sensors and camera lens were clean and free of debris at the time of the incident. This represents a failure of the safety system to perform its primary function of obstacle detection in a standard backing scenario, posing a significant risk for back-over incidents involving pedestrians or other vehicles.
