NHTSA Complaint #11430864 — 2020 FORD EXPLORER

We have returned the vehicle to the dealer 4 times for back-up camera / rear sensor failure. Most recently they had the vehicle from 8/16/2021 to 8/20/2021. Allegedly they replaced the back-up camera. On 8/27/2021 upon returning home from an approximately 3 mile drive, the back-up camera again failed while backing into our driveway. The DIC displayed the message "Back up assistance unavailable." While on vacation in Colorado, the back-up camera failed every day for 2 weeks (8/01/2021 - 8/13/2021). The failure would occur after extended drives at highway speed. On one occasion, the back-up display flickered between the image, blackout, and blue screen. On one occasion both the backup display and the overhead 360 display, displayed only blue screens. Turning off the vehicle and leaving it sit for 30 minutes or more clears the problem. The dealer claims they are unable to reproduce the problem. I have repeatedly told them that the vehicle must be driven for the problem to present itself. Repeatedly starting and shutting off of the vehicle while stationary will NOT produce the problem. We have repeatedly supplied images of the interior display showing the problem. This situation poses risk when reversing from parking place into oncoming traffic.
