“Several of these models are having issues with the routine and design of the power supply and signal from the backup camera due to breaking of the wiring harness. My camera stopped working after opening the tailgate in below freezing weather. I noticed a broken wire in the harness. I checked the Honda Ridgeline forum and many owners are experiencing the same problem. I ordered the oem replacement part and it now is working. I trying to get Honda to refund my parts cost of $68.25. Not including labor of tailgate panel removal along with rear bumper cover. …”

NHTSA complaint #11400366, filed 2021-03, 50,000 miles

“The wiring harness (Honda part #32109-t6z-aoo) between the lift gate and the truck bed for the backup camera is subject to premature failure. My 2018 Ridgeline backup camera quit, and when I did research on the Ridgeline blogs, I found this is a very common problem. The harness itself is surprisingly wimpy for a Honda product. I had mine replaced by my Honda dealer, but my guess is virtually every Ridgeline will experience this failure eventually. I've tried to attach photos of the harness, as well as the email I received from Honda customer service.”

NHTSA complaint #11319870, filed 2020-03, 58,600 miles

“Two way tailgate back up camera wiring broke after only 7000 miles due to poor design, per lia Honda representative.this wire harness supplies back up camera viewing. After 7000 miles I was unable to see what was behind vehicle when backing up. Wires broke due to under engineered harness material. As tailgate can be open in 2 way, up/down and as a swinging out door, harness is not strong enough to endure sure repetitive motion. Dealer informed me that they are seeing many harnesses being replaced and there is now a back order of replacement harnesses. …”
