I was backing out of a parking spot while watching the backup camera when I felt a bump as if I hit something but the camera was showing I have enough space to the cars behind me. It turns out the backup camera image was frozen on the display and I had hit a car parked behind my car. Please investigate and make the manufacturer solve problems with the hardware or the software. Make sure the display shows a warning when the camera fails and the vehicle drives backwards. There may be children behind the car. Shifting into park and then into reverse again caused the camera to work correctly.
