Backup camera failed with a blue screen that was initially identified early August and brought into Ford 8/11-13 but dealership unable to reproduce problem. It is believed that the dealership re-booted the computer and downloaded new software. The same problem occurred just two days after we got the car back on 8/15 at which time a picture was taken to show the service department. A Google search suggested there was a problem with the back up camera for 2020 Explorer, but there was no recall on my VIN. After reaching out to Ford soon after we got the car back, a service person offered to order a new camera, but it was never approved. Numerous calls were placed to the dealership given ongoing camera failure and concern for causing an accident, but we were told that the problem needed to be reproduced. The camera could not be ordered. While backing the car out of our driveway without an operational camera or sensors, driver side rear bumper collided with a car parked in the street. The insurance company was notified the day of the accident and the car was taken to Ford body shop 9/21 where a repair estimate was provided. The dealership service department was notified that the car was involved in an accident because of camera failure and finally agreed to order a new replacement camera. On 9/23, we were notified of a "blue screen" back up camera recall.
