Multi purpose camera behind front mirror failed. Most safety systems will not work. Various warnings regarding system failure were noted on dash. Supposedly a bad battery installed and warranted by dealer caused this problem? dealer covered the battery but charged $2100. 00 to replace the camera!.

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.

While driving with the adaptive cruise control and the road departure mitigation system engaged, then fails and disengages. The warning system indicates a problem that should be reported to the dealer. This has happened on multiple occasions and was repaired by the dealer when the car had 254 miles by replacing the tailgate upper wiring harness and the brake/cruise control switch. The part number replaced was 36750-ty0-j11 35350 sw. Since that repair, the problem has resurfaced at 4385 miles multiple times. After stopping and restarting the car multiple times, the systems apparently resets itself, but the problem reoccurs multiple times after that. I have no confidence that the system is consistently reliable. The problem initially occurred on Jan 17 2025 and again sept 19, 2025.

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.

Every couple drive cycles these lights go amber. Acc, lkas, ldws. Faults at startup. . . After parked, usual over night, it resets itself.

I experienced multiple warning lights on my dash when disengaging my cruise control on the freeway to pass a slower vehicle in front of me. Attached photo depicts these lights and a loss of dash gauges. I arranged a vehicle inspection from the purchasing dealer the next day, but later the entire dash “blacked out” losing speedometer, tachometer, turn signals, back-up camera etc. Given the uncertainty of the safe driving condition of the vehicle I opted to have a closer authorized dealer inspect the vehicle. The consensus was that there was a failure of the dash panel resulting in a $1600. 00 repair. Learning that this exact failure was known to american Honda motor CO. , inc. I reached out to their customer service since like year(s) models of the passport, pilot & odyssey were part of an official warranty recall (along with extended warranty coverage) by american Honda motor CO. , inc. To see if any goodwill assistance would be provided, given what I’m sure are shared components between the three models. Honda declined. In all transparency, I am a retired ahm employee who services my own vehicles, so their decline, I’m told was partially based on the lack of an official service history. The failure that I have described is totally unrelated to scheduled service. In closing, I am attaching a “screenshot” for a Honda pilot owners blog which goes into greater detail of the exact failure I experienced, described as inappropriate software programming. Again, these items in the recall cited fmv ss101 & fmv ss111 as being key reasons for the issuance of the recall. Why the 2020 Honda Ridgeline which experienced this exact failure was excluded is a question that Honda should answer. Thank you.

At times when traffic in opposite lane coming at me on 2 lane road the auto brake system is activated and telling me to apply the brakes. Also, at times the lane departure system will not activate if I drift over into the opposite lane of traffic.
