The rear camera warnings both visual and beeping sound did not activate while backing up. Safety of others was put at risk not warning them that the vehicle was backing up. Because of this failure, I backed into a pole causing the driver's side tail light to be cracked. The problem was reported to Fairway Ford who could not reproduced the failure. They contacted Ford "hotline" and Ford refused to acknowledge the failure. No police report was filed. Ford did not offer to inspect the vehicle. There were no former problems prior to this incident.
