When operating the vehicle in reverse, the dashboard screen was black/blank instead of displaying the view from the rear backup camera. The issue began to occur intermittently at ~40,000 miles and the camera was completely non-operational at 42,163k miles (10/21/2023). Upon investigating and diagnosing the root cause of failure, the dealer determined that the rear backup camera wiring harness failed. The failure point was a flexible section at the rear tailgate hinge that permits opening and closing the rear tailgate. Because the dealer's total replacement cost was too expensive (>$500), the original wiring harness was repaired by the owner. At 50,185 miles, the failure is intermittently occurring again with the repaired harness. A non-operational backup camera puts pedestrians, cyclists and others at risk when the vehicle is backing up because the driver may not be aware of their presence and could strike them or cause a collision. The local dealer diagnosed the issue and subsequently sold the owner a new replacement wiring harness that has yet to be installed. The vehicle or component has not been inspected by the manufacturer, police, insurance representatives or others. No warning lamps, messages or other symptoms of the problem occurred prior to the failure.

The back-up video is not operating on this vehicle. It stopped functioning properly within the past week. In checking on this, it appears multiple other owners of this vehicle are experiencing the same issue and it generally relates to wires being pinched or cut accidently due to apparent design or equipment failure while vehicle is being operated in routine fashion. Specifically, it appears these wires are pinched and ultimately severed when tailgate is being opened/closed. This is an issue as the camera is very important manner for safely backing.

Rear Camera has stopped working. Black Screen. Poor rear visibility when trying to back up causing a safety issue. Same Issue as Service Bulletin 22-049 describes, except this is a 2020 not a 2019.

My rear back-up camera suddenly stopped working. The display screen is fine, but no signal is reaching it. No warnings or messages. Worked one minute, not the next. Looking on-line in the forum, it looks like a common failure of the wiring harness at the tailgate.

Backup camera wires pinched, camera stops working!

The backup camera suddenly went black. I saw this was a problem that led to a recall on earlier models of the Honda Ridgeline. I was fortunate in that the dealer did get it covered by the warranty department. The confirmed it was a wiring problem.

Back camera failed and screen goes black.

- Old Lyme, CT, USA

Rear back up camera stopped working. When putting the truck in reverse the video display only shows the yellow grid lines. The camera video is black. I saw on line that this is caused by a faulty wire harness. There-??s a you tube video showing where the problem is and how to fix it so this must be a common issue. I followed the instructions from YouTube and I took the tailgate apart and found that the camera wire was broken. I spliced the wire back together and now it works again.

- Coldwater, OH, USA

My rear camera stopped working. My understanding is that it is a defect in the wiring harness. My rear camera is not useable, and makes backing up very difficult and is a potential hazard.

My reverse camera was intermittent approximately 2 months ago. It would occasionally flicker, but then went totally dark with no picture. I took it upon myself to investigate for a loose wire as I know this was an items that was recalled on the 2017-19 models as well. I did find a severed wire, which leads me to believe that the same issues that forced a recall on the previous models is also affecting my 2020 Ridgeline. The absence of the backup camera makes backing out of parking space or the potential for colliding with other cars or pedestrians a very real concern.

- Saint Paul, MN, USA

Rear view camera wiring harness broken. Recalls on 2017 to 2019. My truck is built in 1-20 and is out of warranty. Same issue as with previous Ridgeline harness. Safety issues with no backup. Dealer refuses to do anything about it as it is not in current recall and it's out of warranty.

- Mt. Vernon, IL, USA

Back up camera is black with yellow lines

- Northfield, MA, USA

I shifted the vehicle into reverse and the parking assist camera (backup camera) did not appear on the infotainment screen as it should. There is an active recall on the 2017 - 2019 models as Honda is aware of this problem with the tailgate wiring harness design. Backing up without the visual aid poses a serious safety threat to any pedestrians or vehicles that may not be seen due to the camera not working as it should. I have not yet scheduled a repair for this item but will update when the problem is remedied. There was no warning before this occured. It was sudden without any signs. It is my hope and the duty of the manufacturer that this issue is fixed within ALL model years that this problem is known to occur.
