Rear-View Camera Failure
On February 13, 2024, the Office of Defects Investigation (ODI) opened Preliminary Evaluation PE24004 to assess alleged failures of the rear-view camera (RVC) in 2020-2023 Model Year (MY) Honda Ridgeline vehicles. At this time, ODI has received a total of 50 complaints with allegations of the RVC image failing to display when the vehicle was in reverse. The RVC wire harness is routed near the hinge in the tailgate, in a location where frequent opening and closing of the tailgate causes bending stress on the harness. Honda determined the wire harness was manufactured with a material which is permeable to water and salt, which when it freezes and thaws, combined with tailgate usage, ultimately leads to breakage of the wiring in the tailgate harness. This results in a failure to display the RVC image. On May 9, 2024, Honda filed a Part 573 Safety Recall Report recalling all 2020-2024 MY Honda Ridgeline vehicles. The dealer will replace the RVC tailgate harness with a wire harness that is manufactured by a new supplier and has improved material properties to withstand wear from bending. In view of Honda filing recall 24V‑321 addressing the subject of this investigation, ODI is closing this Preliminary Evaluation. the federal safety agency reserves the right to take additional action if warranted by future circumstances.

Most recent owner complaints, unedited.
When driving the vehicle suddenly displayed warning and failure lights for the following: Adaptive Cruise Control, Lane Keep Assist, Road Departure, High Beam Support, and Collision Mitigation. The vehicle in the past regularly experiences issues with oncoming traffic (especially on 2 lane roads) when it comes to auto braking and forward crash warnings so I immediately brought the vehicle home as I was worried for my safety and the safety of others on the road that if these systems were now warning of malfunction the vehicle might auto brake in traffic for no reason and cause a crash. I took the vehicle in following this as I looked online and discovered there were multiple recalls on this vehicle for other various issues and I wanted the dealer to fix those in addition to determining if this was part of one of the recalls also. The dealership has diagnosed the issue as the forward multi-purpose camera and is stating it needs to be replaced to correct the safety issues of the vehicle. I reviewed online and found that just a coupe years ago this part was approx $800 and the dealer is not charging over $1600 for the part. The other issue is that I paid for the part and the dealer claims this part will not even ship until August 26 (over a month away). Additionally I have further researched this issue and found that it is a common failure on Honda and Acura vehicles and creates a major safety concern, yet Honda Motors has refused to address the issue and handle this as a recall as it should be done. New vehicles should not be regularly experiencing catastrophic safety system failures regularly and the manufacture not be held liable for the damages and not be able to fix the part or car in a timely manner. The fact the parts are in such short supply and backorder further attests to the common failure of this part. I would appreciate your immediate review and action of this matter to ensure that Honda is held accountable for the major safety failures they have created.
My 2021 Honda Ridgeline Sport experienced failure of the forward-facing Honda Sensing camera system. This camera controls safety features including Collision Mitigation Braking, Lane Keeping Assist, and Adaptive Cruise Control. The failure disables safety assistance features. Honda acknowledged the issue but refused to provide full repair coverage and only offered $941 toward a repair costing significantly more. I believe a safety-related camera failure should be investigated as a potential defect

I was involved in a rear end collision earlier today. My vehicle sustained significant front end damage and the air bags did not deploy. The vehicle had to be flat bedded to a Massachusetts State Police Barracks, pending further action by my insurance company. There were no injuries.
Forward brake assist, collision mitigation, auto headlight dash lights came on sporadically. As of today the lights are now on constant and unable to clear. Advised that the forward facing camera most likely died and a replacement due to recalibration would be 1500-2000..
2021 Honda Ridgeline RTL-E. Part number 36160-T6Z-A62-M1 failure, hard code U3000-49. Results in total loss of Honda Sense Safety system. Including Collision Mitigation Braking System, Road Departure Mitigation System, Adaptive Cruise Control, Lane Keeping Assist System, Traffic Sign Recognition, Auto High-Beam Headlights. This appears to be a fairly common issue across Honda models where the multipurpose camera fails, generally due to heat from exposure to sun. The replacement cost and required re-calibration via the dealer is ~$2000. Living in northern California with extreme heat, I will assume this problem will resurface after a few years resulting in another $2000+ repair.
The forward collision system frequently goes off from a vehicle simply driving in their lane normally. The truck alarms, shakes the wheel, and sometimes brakes automatically. This is alarming for my kids riding in the car and the braking is dangerous for cars behind me. This could cause a rear end collision.
At 48,000 miles, the vehicle began to experience multiple Advanced Driver Assistance Systems problems, including Adaptive Cruise Control, Forward Collision Warning, Automatic Emergency Braking, Forward Collision Warning, Lane Departure Warning, and Lane Keeping Assistance, which rendered all these systems inoperable. Systems that were designed to mitigate collisions became non-functional, and continuous warnings on the dashboard were a distraction while driving. Dealer scanned the vehicle with a code U300-40 Multipurpose Camera Unit/Millimeter Wave Radar Internal Electronic Failure, and diagnosed a failure of the multipurpose camera, which was then replaced and recalibrated. I have retained the failed unit after paying to have the replacement installed and calibrated. All warning lamps for the above mentioned systems flashed on my dashboard every time the vehicle was started, prior to the dealer repair. The safety of the driver and those around them was affected because repairs for this safety feature suite may be cost prohibitive to some ($2000) and they just won't fix it.
