| Sep 2025 | ELECTRICAL SYSTEM,FORWARD COLLISION AVOIDANCE | 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. | Crash: No Fire: No | Unknown |
| Sep 2025 | FORWARD COLLISION AVOIDANCE,LANE DEPARTURE | When turning on vehicle the attached picture’s warning lights show on dashboard. Unable to reset them. Vehicles collision sensor not engaged when driving. Road departure will not activate when vehicle drifts of interstate lanes. Cruise control will not work at all. Brake system light will not reset even when brakes and fluids are good. With all these issues, vehicle safety devices don’t provide any safety. These could result in bodily injury and even death. | Crash: No Fire: No | Unknown |
| Sep 2025 | ENGINE,FORWARD COLLISION AVOIDANCE | On [XXX], while driving my wife to the RDU airport, our Odyssey's engine failed to restart after an Auto Idle Stop (AIS) at a busy intersection in Greensboro. Instead of starting, the dashboard displayed a Collision Mitigation System Problem alert, the Drive ("D") indicator light started flashing, and then the dashboard displayed a "Shifting to Park: Apply Brake Pedal" message. We were stranded at a busy stoplight, at the front of a dedicated left-turn lane, unable to drive or shift to park as instructed. The only way to resolve the issue was to hold the Start/Stop button for several seconds to shut the vehicle off. And the vehicles behind us had to swerve around us because our malfunctioning vehicle was blocking the lane. This problem has recurred semi-regularly since [XXX], forcing us to manually disable the Auto Idle Stop feature on every drive to prevent being stranded in traffic. An independent mechanic found no stored diagnostic codes but identified relevant Honda Technical Service Bulletins (23-008 and 23-009) addressing similar AIS failures. A Honda service center misdiagnosed the issue as a faulty battery, but subsequent testing by the independent shop confirmed the battery was in excellent working order. The actual Auto Idle Stop malfunction remains undiagnosed. The vehicle and its Auto Idle Stop system remain available for inspection. This issue appears to be part of the ongoing NHTSA Engineering Analysis EA25-004. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6) | Crash: No Fire: No | Unknown |
| Sep 2025 | ELECTRICAL SYSTEM | The contact owns a 2020 Honda Odyssey. The contact stated that on two occasions while driving with the idle stop feature engaged, while the vehicle was idling and stopped, the engine failed to restart as intended when the brake pedal was released. The vehicle was restarted and operated normally. The vehicle was then taken to a dealer however, the failure was not able to be duplicated. The manufacturer was notified of the failure. The failure mileage was approximately 88,000. | Crash: No Fire: No | 88,000 |
| Sep 2025 | BACK OVER PREVENTION | Rear view screen turns off due to radio not working due to FAKRA connectors. | Crash: No Fire: No | Unknown |
| Aug 2025 | ELECTRICAL SYSTEM | Sliding doors don’t close. “Left sliding door problem” flashes on dash often. Have to force doors to close all the way. They try to close and then recoil. | Crash: No Fire: No | Unknown |
| Aug 2025 | LANE DEPARTURE,FORWARD COLLISION AVOIDANCE | The Multipurpose Camera Unit failed in my 2020 Honda Odyssey. This camera is responsible for enabling multiple advanced driver-assistance systems, including the Collision Mitigation Braking System (CMBS), Lane Keeping Assist System (LKAS), Road Departure Mitigation System (RDM), Adaptive Cruise Control, and Auto High Beams. The component has not been replaced yet and is available for inspection upon request. The failure of the camera disabled multiple critical safety systems while the vehicle was in operation. These systems are designed to prevent lane departures, collisions, and unintentional road exits, especially at higher speeds. With the systems offline, I was at increased risk of collision or lane departure, particularly on highways or in low visibility conditions. This malfunction removed key layers of protection that the vehicle is designed to provide. The issue was confirmed by a Honda dealership on August 8th 2025, which diagnosed the problem as a failed multipurpose camera unit. They acknowledged that this malfunction disables all related safety systems. The vehicle was inspected by a certified Honda dealership technician, but not by police, insurance, or the manufacturer directly at this time. Multiple dashboard warning messages appeared simultaneously one day when starting the vehicle, including: "Collision Mitigation System Problem" "Road Departure Mitigation System Problem" "Lane Keeping Assist Problem" "Adaptive Cruise Control Problem" "Auto High-Beam Problem" These messages first appeared on or around the end of June 2025, and the systems were disabled immediately upon the failure. | Crash: No Fire: No | Unknown |
| Aug 2025 | FORWARD COLLISION AVOIDANCE,LANE DEPARTURE | Multiple warnings regarding Adaptive cruise control, lane keep assist, and lane departure warning problems. Honda says it is the front multi-camera. The vehicle works fine intermittently, but doesn’t more often than not. Issue started to occur shortly after a wiring harness recall. | Crash: No Fire: No | Unknown |
| Aug 2025 | AIR BAGS | The contact owns a 2020 Honda Odyssey. The contact received notification of NHTSA Campaign Number: 24V064000 (Air Bags). The local dealer was contacted and confirmed that parts were not available. The vehicle was not diagnosed or repaired. The manufacturer was not contacted. The contact had not experienced a failure. | Crash: No Fire: No | Unknown |
| Aug 2025 | ELECTRICAL SYSTEM,ENGINE,FUEL/PROPULSION SYSTEM | My car went completely dead while stopped in traffic on a busy street. My kids were in the car and thankfully I was able to crank it by pressing the start button. This issue has already been “fixed” and the dealership “cannot replicate” | Crash: No Fire: No | Unknown |
| Aug 2025 | ELECTRICAL SYSTEM,LANE DEPARTURE,FORWARD COLLISION AVOIDANCE | 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. | Crash: No Fire: No | Unknown |
| Aug 2025 | AIR BAGS | While driving at approximately 12 mph on slightly snowy roads, my vehicle slipped and made a light impact with the sidewalk curb. Despite the minor nature of the collision, the entire left-side curtain airbag and seat airbag deployed with full force, as if a severe accident had occurred. This deployment was unexpected and excessive given the low-speed impact. I have found multiple online reports of similar incidents involving premature or overly sensitive airbag deployment in Honda vehicles, which raises concerns about a potential safety defect. Concern: I believe this may indicate a flaw in the airbag deployment system or sensor calibration. This poses a safety risk and could result in unnecessary injuries or repair costs | Crash: No Fire: No | Unknown |
| Aug 2025 | FORWARD COLLISION AVOIDANCE,LANE DEPARTURE | For the past couple of weeks, every time I drive the car, I get a number of error messages regarding problems with the advanced driver assistance features. These include: "Adaptive Cruise Control Problem", "Collision Mitigation System Problem", Lane Keeping Assist Problem", "Road Departure Mitigation System Problem", and "Auto High-Beam Problem". A diagnostic check showed error U3000-49, namely "Control Module Internal Electronic Failure". I took it to a shop, they ran diagnostics and told me I needed to replace the multifunction camera in the windshield. It seems to be a common problem and is very expensive to fix, at more than $2000. | Crash: No Fire: No | Unknown |
| Aug 2025 | ELECTRICAL SYSTEM,FORWARD COLLISION AVOIDANCE | 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. | Crash: No Fire: No | Unknown |
| Aug 2025 | ENGINE | Engine recently began making noise and the car was taken into Honda. The dealer checked engine components to find the cause and recommended that we remove oil pan to inspect the issue because they assumed it might be engine bearing related. Before we could schedule the service I was driving with my family on the highway when we heard a loud noise and complete loss of power. I was able to move over avoiding other cars to reach the shoulder and come to a stop. The car would not start or go into any gear. Car was towed to shop. What component or system failed or malfunctioned, and is it available for inspection upon request? The car has not been inspected yet. Currently at shop being evaluated. Has the problem been reproduced or confirmed by a dealer or independent service center? Engine was making noise at the dealership when it went for service. There was no concern made by dealer stating car was unsafe to drive. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? Was inspected before the car broke down, but currently being evaluated by local shop. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? There was an unknown noise coming from the engine, and dealer stated they needed to remove oil pan to diagnose the noise but stated it could be bearing related. The dealership did not say the car was unsafe or should not be driven. Before we could look into the issue more the car broke down on the highway. | Crash: No Fire: No | Unknown |
| Aug 2025 | FORWARD COLLISION AVOIDANCE,LANE DEPARTURE | All Honda Sensing technology is not working and brake system indicator is on. ACC, LKAS, Collision mitigation, auto high beam, road departure. I read online that a lot of Honda Odyssey owners are experiencing same problem. It could be the front camera sensor.I have always had electrical problems with car. There crackling sounds when the radio or music is playing on the stereos. | Crash: No Fire: No | Unknown |
| Aug 2025 | STRUCTURE | The rear hatch will randomly close after it is opened. The hatch will not stop closing if someone is standing under it. Several times now it has closed while someone is getting something out of the back and you can not make it stop without quickly getting out of the way and pressing the button. Both, myself and my wife have been hit pretty hard on the head by the hatch closing on us. This is a HUGE safety concern as I have children that could easily be harmed by the sheer power of this hatch. I have had the issue inspected by an independent shop and was informed that it would need both new power struts at a cost of over $1,200! The van is only 5 years old with 75,000 miles! There are no warning lights, messages or problems prior to the failure. | Crash: No Fire: No Injuries: 1 | Unknown |
| Aug 2025 | FORWARD COLLISION AVOIDANCE,LANE DEPARTURE | The front camera is malfunctioning, affecting all of my safety sensors. | Crash: No Fire: No | Unknown |
| Aug 2025 | FORWARD COLLISION AVOIDANCE,LANE DEPARTURE | While driving, all at once several messages displayed, all of which are related to forward facing camera. Adaptive Cruise Control Problem, Collision Mitigation System Problem, Road Departure Mitigation System Problem, Auto High Beam disabled along with the BRAKE SYSTEM light turning on When I researched the internet, there are alot a people report this problem with the HONDA forward facing camera witch supports the systems listed this failures. Talking to friends and neighbors they have had the same issues, it is about a $2000 fix to replace and recalibrate the camera link to user forum [XXX] Most of the reported issues including mine are related to heat, the camera is in an enclosure located at the top center of the windshield. We just had heat indexes above 100 degrees. The camera is always hot to the touch. I also had this issue in the past put happened whole under warranty.

| Jul 2025 | ELECTRICAL SYSTEM,EXTERIOR LIGHTING | 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. | Crash: No Fire: No | Unknown |
| Jul 2025 | LANE DEPARTURE,FORWARD COLLISION AVOIDANCE | The multipurpose camera in the vehicle failed, causing multiple warning lights to come on related to the collision warning, blind spot warning, lane keep assist, lane departure warning, adaptive cruise control, and others. The dealership said it needed to be replaced, as it was no longer working and none of these features would work without replacement | Crash: No Fire: No | Unknown |
| Jul 2025 | FORWARD COLLISION AVOIDANCE | The multipurpose camera that sits behind the windshield has completely failed, deactivating many automated safety features. The dealer quoted $2700.00 to replace. | Crash: No Fire: No | Unknown |

| Jul 2025 | FORWARD COLLISION AVOIDANCE,LANE DEPARTURE,BACK OVER PREVENTION | The ADAS front windshield camera failed on our 2020 Honda Odyssey. This vehicle is too new to have a failure like this and this is a very common issue that I have seen across all Honda Odysseys of same generation. Honda needs to be held accountable. | Crash: No Fire: No | Unknown |
