The vehicle's front-facing monocular camera experienced an internal component failure that triggered a permanent error code U3000-49. This hardware failure instantly disabled multiple core safety features simultaneously, including the Adaptive Cruise Control, Lane Keeping Assist (LKAS), Road Departure Mitigation, and Collision Mitigation Braking System (CMBS) ABS Braking and High Beam Support with all dash lights remaining on. The sudden, unexpected loss of automatic safety braking and driver-assist features while moving poses an immediate highway safety risk.

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.

Condition: truck is stopped, the auto engine idle is on Action: release the brake to press the accelerator Result: the truck fails to restart, shuts off the engine completely, puts itself in Neutral, and all the lights in the dash illuminate I have to place the truck in Park and restart the engine. Sometimes the engine is difficult to restart, and I have to try several times. This has happened 3 times since November, and 3 other times the truck has almost stalled when restarting.

Beginning about 3 months ago the Automatic Idle Stop (AIS) would randomly not function at start-up during the length of a drive though there was no indication of any issue on the dash. Shutting off and restarting would allow usually allow it to function normally. About 6 weeks ago the AIS stopped the engine at a red light, and when I removed my foot to accelerate the engine did not start, the car shut off. It took a couple of seconds to realize the vehicle was down, I had to shut the car completely off and restart to get moving almost getting rear-ended since I did not move when the light changed even though my brake lights went off, confusing the driver behind me. AIS failing to start has become more frequent and now happens at least every other day. In traffic this is a safety issue for sure. Additionally, the LKAS system randomly displays a new message on the dash that it is disabled for a few seconds while driving on the freeway and then clears itself. Other seemingly related electrical issues started at the same time. On several of the occasions that the AIS failed to restart, All dash lights flickered rapidly, and the speedometer needle bounced wildly. after shutting down and restarting the A and B Trim computers had been zeroed as well as the MPG average being zeroed, and the Economy mode had been switched of. These nuisance electrical issues are not a safety concern themselves but may help point to a common failure which does cause the safety issues of the AIS and the LKAS systems. I believe you are investigating similar AIS issues on the Honda Pilot which shares many of the electrical and drive train components with the Ridgeline.
