Hello. Welcome to Just Answer. Please allow me to assist you. Normally, this happens whenever the front sensor is malfunctioning. A light impact upon it (like someone backing up into the front bumper) can cause the element to fail. There may not be visible damage, but any 2-3 mph impact is enough to jar the detector to a failure. I would recommend replacing the sensor.
