Dash has warning light showing "Power Tailgate Problem", and power tailgate will not function. The next day there was heavy rain, and the dash had a flickering warning showing the tailgate was open. This also caused the interior lights to flicker on and off as the tailgate open warning was flickering on and off. I returned the van to my home for fear that the tailgate would open automatically while driving down the road. I had the tailgate control module replaced on February 27, 2025 for this same issue, which was due to a tailgate seal leaking water onto the tailgate control module that shorted the module. This is now the second time within less than one year this same module has shorted out. This is a known issue with a class action lawsuit already filed against Honda that should result in a recall. The potential danger of the tailgate opening while driving makes this minivan not usable to transport my kids for fear of their safety.

Make: Honda Odyssey 2020 Mileage at Failure: ~40,000 miles Incident Description What component or system failed or malfunctioned, and is it available for inspection upon request? The front sensing camera system failed, which controls multiple driver-assistance features, including Adaptive Cruise Control (ACC), Lane Keeping Assist System (LKAS), Lane Departure Mitigation, and Collision Mitigation Braking System. When the issue occurred, all related dashboard warning lights illuminated simultaneously. The vehicle’s front camera module is still installed and can be made available for inspection upon request. How was your safety or the safety of others put at risk? When the camera malfunctioned, all driver-assistance and collision-avoidance systems were disabled without warning. This created a serious safety concern because the vehicle unexpectedly lost its lane-keeping, adaptive cruise control, and collision mitigation capabilities while in motion. It increased the risk of a crash, especially during highway driving or when relying on these systems for lane and speed control. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes. The Honda dealership confirmed the issue after diagnostic testing and stated that the front camera module had failed and must be replaced. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives, or others? The vehicle has been inspected by the authorized Honda dealership. Were there any warning lamps, messages, or other symptoms of the problem prior to the failure, and when did they first appear? Yes. The dashboard displayed multiple warning messages, including: ACC, LKAS, Collision Mitigation, Lane Departure Mitigation These warnings appeared suddenly at approximately 40,000 miles and have persisted since. The dealer quoted $2500 Also I found numerous reports from other Honda owners experiencing the same camera-system failure at low millages.

The Infotainment system started blanking out and restarting while driving. This issue has started about 1 year ago to this date. it has occured on multiple occassions, We have brought it to Honda to get it repaired under warranty but they refused. The refusal was due to the fact that they could not "duplicate" the issue regardless of having Video Proof of the issue. The second issue is the Multipurpose camera Malfuncition. My vehicle is no longer under warranty and now I have to shell out $800 USD to fix this issue. All the lights have popped up on the Dash. Both issue have not been adressed by Honda, they refuse to fix the issue with countless other electrical problems that this van has aquired over the short lifespan of this vehicle.

Complete infotainment system loss and screen blackouts Repeated “Network connection lost” errors Inoperative reverse camera and parking assist systems Ongoing 12V battery drainage due to system faults My Honda dealer has diagnosed the problem as a defective floor wire harness and advised that the entire harness kit must be replaced at an estimated cost of approximately $7,000. While I greatly appreciate the 80% goodwill coverage already offered, the remaining $1,400 out-of-pocket expense is still a significant hardship — particularly since this is a known and documented defect affecting vehicle safety systems. This issue directly impacts the federally mandated rear visibility system (FMVSS 111), rendering the reverse camera and related safety functions inoperative. As such, this is not simply a convenience or infotainment problem, but a critical safety concern. Honda is charging $7000 to fix it and now it says it’s the floor harness kit. They are only covering 80%. I’m required to pay 1400 even though this is a known problem with this vehicle and it’s been occurring since I have owned the vehicle due to multiple visits to the dealership for a resolution, thousands of dollars being spent trying to figure out what it was, we already replaced the head unit and Head unit harness, multiple sensors on the doors, which were not even necessary because the battery was draining from the head unit and now I have no camera and my car is crashing and shutting off and Honda is refusing to escalate

The Infotainment system continually goes blank, while driving leaving the backup camera disabled and without navigation. I returned the van a week after purchase and did not get it back for a month. Despite the recall was never completed. It has been back to the dealer 6 times for the same issue with no improvement. Currently the problem still exist and the dealer WILL NOT HONOR the uncompleted RECALL ISSUE. The dealer insists the recall was completed yet the original issue was never resolved and is saying I will need to cover all costs.

I am submitting this complaint regarding a faulty Multi-Model Seat Weight Sensor (SWS) in my 2020 Honda Odyssey. I understand that NHTSA Recall 24V-064 covers this issue for certain vehicles; however, my VIN is not included, even though my vehicle is exhibiting the same malfunction described in the recall notice. Multiple independent mechanics and certified airbag technicians have inspected my vehicle and confirmed that the SRS (Supplemental Restraint System) circuit is open, indicating that the front passenger airbag will not deploy in the event of a collision. This represents a serious safety hazard consistent with the defect outlined in the official recall documentation (NHTSA Recall 24V-064 Report: [XXX] ) The warning light for this malfunction was present when I purchased the vehicle in August 2025.

Honda Odyssey Idle Stop system failure Vehicle: 2020 Honda Odyssey (Elite) Incident description: While driving, the vehicle's "Idle Stop" system engaged as I came to a complete stop at [e.g., a traffic light, intersection, stop sign]. The engine shut off as designed, but failed to restart automatically when I released the brake pedal. This left my vehicle stalled and disabled in the middle of [e.g., an intersection, a lane of traffic] with no forward power. I was scared as there were lots of cars behind me in the intersection. This has happened over a dozen times. Safety risk: This failure created an immediate and dangerous safety hazard. My vehicle was a risk for being rear-ended by traffic from behind, and my family was stranded in a vulnerable position. The vehicle was unable to move out of harm's way, and I had to put the vehicle in park and manually restart the engine. This is unacceptable for a system designed to work seamlessly and automatically. Additional information: This is not an isolated incident. The auto start-stop failure has occurred multiple times since March 2025. The system failure has put me and my passengers in a position of significant risk multiple times. Failed component: The vehicle's "Auto Idle Stop" (AIS) system, which failed to restart the engine after it was automatically shut off. Resolution: An immediate and permanent recall is necessary to address this dangerous defect. Existing service bulletins have not corrected the problem. I urge the NHTSA to require Honda to provide an effective, long-term solution to ensure the safety of Odyssey owners.

The car had a leak in the trunk that was not our fault it was not due to an accident but rather came that way when we bought it brand new. We were unaware of this leak and now our entire trunk control panel is flooded and the trunk is totally useless as it will not open at all, not even manually. The only way to open it is to crawl to the back and open it from the inside. I asked Honda for a diagnostic and it cost me $200 for them to tell me “yeah we see this issue a lot in the older odyssey” and that it would cost over $1000 to fix. But this was not normal wear and tear or anything caused from lack of care in my part but it was made that way. I am shocked that when I did research on this issue it was happening to ALOT of people and idk why this isn’t part of the recall list.

The multipurpose camera in mounted underneath the rearview mirror stopped working. No apparent reason for the malfunction to shut the vehicle off while filling gas and then five different warning lights occurred, including issues with lane keep assist, adaptive, cruise control, automatic, breaking, and several other safety features no explanation for the failure when that vehicle was taken to the dealer and currently being charged $2500 for a replacement of the camera and labor associated with the repair. My belief is that the system is malfunctioning due to overheating, which is a design issue associated with the vehicle and isn’t something that I should be responsible for.

The forward-facing camera and/or radar unit failed one morning while running errands, resulting in 5 separate ADAS system failures. With these safety features not working, our safety and the safety of others is at risk. We took it to our dealer and were told we would have to pay a diagnostic fee of $205, even though they clearly already knew what the problem was- based on the multiple complaints through NHTSA and various other forums and websites from Odyssey and other Honda model owners and across multiple years. The problem was confirmed by the dealer and they quoted us $2025 and we're still not sure if that includes just the camera and/or the radar unit, which is another $600 part. Other dealers have quoted only $1200 to fix the exact same thing, with others charging more than double that. The 5 separate warning messages scroll across our screen repeatedly and are very distracting as you're driving. With multiple electrical issues already in recall status by Honda, this is another one that they should be taking responsibility for and not dumping this defective electrical repair on their customers. Who's to say that we won't be in this exact same predicament 3 or 5 years from now if the part or parts aren't fixed! Definitely expect more from Honda... very disappointed and feel betrayed by the inferior parts they're passing on as quality products.

Several months ago my wife was driving when the automatic brake system engaged when a car was turning in front of her. This engagement startled her and she felt the emergency braking was unnecessary considering the speed and distance the car was in front of her. This incident concerned her and made her lose confidence in the safety of the car. Then just recently we began encountering a almost consistent but sometimes intermittent brake System Error along with multiple trouble notices about problems with Road Departure Mitigation System, Lane Keep Assist System, Collision Mitigation Braking System, Adaptive Cruise Control, etc.. when using the car. We received an error code U3000-49 reporting an Internal electronic failure in the multipurpose camera unit. Online searches of this issue seem to be very common and concerning on how many are occurring considering this is a safety system. Our van has approximately 54,000 miles on it.

The auto idle start/stop feature failed to recognize a bad battery and shut the car off while I was stopped in the left turn lane. The vehicle failed to start and lost all power, including hazard lights and brake lights. I had no way of indicating to other drivers behind me that the vehicle was disabled other than getting out of the vehicle and waving them around me. This happened while I was taking my son to school and could have resulted in us getting in an accident or causing another accident. Honda was not able to identify root cause and replaced the battery. I do not trust this vehicle as reliable or safe any longer.

My Vehicle was at the dealer for service in March of 2025. At that time they performed RECALL 23-008 although the vehicle did not have issues with the idle stop system. Since some time in June, at multiple occasions, the vehicle shifted to Park on its own when restarting from idle stop. Last night, the vehicle fully shut off and lost all electrical power when restarting from idle stop leaving me stranded in the dark at a busy intersection without the ability to turn on my hazard lights. The vehicle repowered after a few minutes. When the system restarted, the info-tainment system activated the anti theft software which happens during full power loss.

I was told by Honda dealership that theres a water leak that's causing it. Along with replacing the unit they are trying to seal it but it's still failing.
