Forward collision avoidance

2 reports
“The system falsely beeps and displays collision alerts even when no vehicles or objects are present. The system has also initiated braking on the highway with no obstacle present, which is a major safety concern for me and for other drivers. Conversely, when an actual vehicle approached too closely, the system failed to alert or respond at all.”
