| Date | Component | Summary | Severity | Mileage |
|---|---|---|---|---|
| May 2026 | FORWARD COLLISION AVOIDANCE,LANE DEPARTURE | The ADAS system doesn't work. The forward collision system, adaptive speed control, and lane keeping assist have all shown malfunction errors and no longer work. | Crash: No Fire: No | Unknown |
| May 2026 | ELECTRICAL SYSTEM | My 2020 Honda Odyssey power tailgate has failed due to water intrusion through defective rear body seam sealer, a known manufacturing defect. Water leaked into the rear driver's side panel and damaged the power tailgate control module, making the rear door inoperable. I took my vehicle to the Honda dealership, who confirmed this is a factory defect related to improper seam sealing. The quoted repair cost is over $8000. Honda has declined to cover this under warranty. This defect poses a safety risk as the tailgate can open unexpectedly while the vehicle is in motion. I am aware of a pending class action lawsuit involving 2018-2021 Honda Odyssey models with this same defect. No recall has been issued. I am requesting thr NHTSA investigate and compel Honda to issue a formal recall. | Crash: No Fire: No | Unknown |
| May 2026 | ELECTRICAL SYSTEM,UNKNOWN OR OTHER | Screen does not work, diagnosed as an internal failure of infotainment system radio unit. Rear camera does not work posing a safety issue | Crash: No Fire: No | Unknown |
| May 2026 | FUEL/PROPULSION SYSTEM | High pressure fuel pump failed on a low mileage 2020 Honda Odyssey. Upon initial inspection the Honda mechanic reported the area around the fuel pipe was saturated with fuel. | Crash: No Fire: No | Unknown |
| May 2026 | ELECTRICAL SYSTEM | I had a recall done in the radio that didn’t work. | Crash: No Fire: No | Unknown |
| May 2026 | FORWARD COLLISION AVOIDANCE,LANE DEPARTURE | The warning messages keep popping up regarding the lane assist system, Adaptive cruise control not working and dealer states that the camera needs replacement and this is common issue for most Honda cars so should be recalled | Crash: No Fire: No | Unknown |
| May 2026 | FUEL/PROPULSION SYSTEM | Vehicle stopped at red light, idle start/stop stopped engine. At green light, upon pressing on gas engine started, vehicle ready to move, but stalled. This happened a few times. Took it to Honda who said they know about this issue and that the Isle start/stop is not a “perfect” system. Tried to sell me an expensive battery. Huge concern in terms of safety in a vehicle with children and stalling in busy streets. | Crash: No Fire: No | Unknown |
| May 2026 | ELECTRICAL SYSTEM,STRUCTURE | Sliding doors sometimes do not close all the way and then reopen automatically. You cannot press the sliding doors to close and walk away. You have to stay to make sure they close because often times it will kick back and reopen. You have to manually help push the sliding door to close. Elite trim has no way to make the doors be able to be closed manually, if needed. Took it to Honda, they said they have never heard of doors not closing and reopening so they could not help me, but I have spoken to quite a few Honda Odyssey owners in parking lots and they all stated that the doors do sometimes not close all the way and return to being fully open. Maybe the motor for the doors isn’t strong enough and depends on vehicle tilt or the temperature outside, but for whatever reason the automatic doors are randomly not fully closing. | Crash: No Fire: No | Unknown |
| May 2026 | ELECTRICAL SYSTEM,UNKNOWN OR OTHER,FORWARD COLLISION AVOIDANCE | Vehicle suddenly starts having multiple lights and warnings come up such as road departure mitigation, adaptive cruise problem, collision mitigation, auto high beam, etc. reading online it seems multiple people with honda oddysey are experiencing the same issues. | Crash: No Fire: No | Unknown |
| May 2026 | ELECTRICAL SYSTEM,FUEL/PROPULSION SYSTEM,LANE DEPARTURE | The blind spot system was a problem when I purchased the car, it spent 15 days in service in the first 30 days of ownership to address the issues. Now, I after another light came on I discovered 9 open recalls on the vehicle that were not disclosed prior to purchase. | Crash: No Fire: No | Unknown |
| May 2026 | ELECTRICAL SYSTEM,STRUCTURE,UNKNOWN OR OTHER | I own a 2020 Honda Odyssey and I am currently having a safety issue with the power tailgate. Upon inspection by my Honda dealership, my vehicle requires a new power tailgate control unit and floor harness and my roof rail and clips need to be re-sealed and replaced. It was discovered that due to the break in seal the connectors corroded due to a water leak.In April of 2026 I received multiple warning messages on my dashboard. The first was Power tailgate problem and the second was keyless remote problem. At first I noticed my car continuously beeping while driving along with the warning on my dashboard. I attempted to turn the vehicle off to see if it would reset, but it did not. I attempted to open and close my tailgate. I could only open my tailgate with the push button on my dashboard. I had to manually close my tailgate due to my buttons on my car and my key fab failing to work. Next while driving, I could hear the locking mechanism on my tailgate continuously locking and unlocking. Of course this particularly concerned me because I have 3 young children and their safety as well as mine was in danger. It was unclear if my tailgate was going to open while driving. Such an action could potentially cause a serious threat or harm to myself, my family or other vehicles on the road. | Crash: No Fire: No | Unknown |
| May 2026 | LANE DEPARTURE,FORWARD COLLISION AVOIDANCE | While driving the vehicle under normal conditions, multiple advanced driver assistance and safety systems suddenly became unavailable without warning. The systems affected include Automatic Emergency Braking, Forward Collision Warning, Lane Keeping Assistance, and related safety features that rely on the forward-facing camera. The failures occurred at the same time and were indicated by warning messages displayed on the instrument panel. The vehicle was inspected by an authorized dealer, who confirmed a diagnostic trouble code indicating an internal electronic failure of the forward multipurpose camera. The failed component is installed behind the windshield and is available for inspection upon request. The dealer stated that no accident, physical damage, misuse, or external cause was identified. After the camera failure was identified, the vehicle also briefly displayed a transmission system warning message that later cleared on its own. In addition, the center display screen has shown unstable behavior while driving, including unexpected resets and flashing back to the navigation screen. The sudden loss of collision mitigation, lane assistance, and warning systems reduces the vehicle’s ability to assist in avoiding crashes, particularly in emergency situations, and increases safety risk to the driver, passengers, and others on the road. | Crash: No Fire: No | Unknown |
| May 2026 | ELECTRICAL SYSTEM,VISIBILITY/WIPER | Backup camera stopped working for no reason, says camera system failure and is a black screen. Research says this is a recall but my dealership says it is not. | Crash: No Fire: No | Unknown |
| Apr 2026 | ENGINE AND ENGINE COOLING,ENGINE | The contact owns a 2020 Honda Odyssey. The contact stated that the vehicle made an abnormal ticking sound while depressing the accelerator pedal, and the engine made a loud sound. There was no warning light illuminated. Upon investigation, the contact related the failure to NHTSA Action Number: PE25008 (Engine). The vehicle was taken to the local dealer, where it was diagnosed and there were metal shavings found in the engine oil. The dealer determined that the engine needed to be replaced. The vehicle was not repaired. The manufacturer was contacted and confirmed that there was no recall or warranty coverage for the repair. The failure mileage was approximately 85,000. | Crash: No Fire: No | 85,000 |
| Apr 2026 | FORWARD COLLISION AVOIDANCE,LANE DEPARTURE | We went to a car wash and that day after the car wash we started getting 6+ error message codes for adaptive cruise control, lane assist, lane departure, blind spot, rear cross traffic, etc. our tech that we took it to says they have seen this happen nation wide on these vehicles | Crash: No Fire: No | Unknown |
| Apr 2026 | ELECTRICAL SYSTEM,ENGINE,FUEL/PROPULSION SYSTEM | Our Odyssey is equipped with idle stop. Sometimes when idle stop engages, the engine won't start again afterwards. We need to turn the car off completely, and then try again. Usually it turns on after doing so. We try to always turn off the idle stop when we start up the vehicle, but sometimes forget. This hasn't led to an accident yet, but has led to some angry vehicles when we can't move when a traffic light turns green. To be clear, this was not an isolated incident, but happens somewhat regularly if idle stop isn't turned off. Honda dealers have told us they don't have any fix, and have recommended that we could purchase a third party "idlestopper". | Crash: No Fire: No | Unknown |
| Apr 2026 | FORWARD COLLISION AVOIDANCE | 5 alerts came on the dash stating lane keeping assist problem , collision mitigation problem , auto high beam problem, forward collision problem and brake system warning. All safety features on my vehicle have failed. I | Crash: No Fire: No | Unknown |
| Apr 2026 | FORWARD COLLISION AVOIDANCE,LANE DEPARTURE | Front camera is bad or faulty, triggering all adaptive cruise control, lane keep assist, auto high beam etc errors on dashboard, rendering the car not able to start or die in the middle of the road/traffic when the engine goes into idle mode while stopping at red lights. My odessey has over 111k miles when these issues start showing, but lots of people report experiencing same issue with even with their newer odessey. It doesn’t feel right why Honda installed cheap cameras especially when it plays a crucial role involves safety of the car and the driver. | Crash: No Fire: No | Unknown |
| Apr 2026 | AIR BAGS,SEAT BELTS,SEATS | The rear passenger side tire hit a pothole and it caused all of the airbags to deploy on April 6, 2026. The impact should not have set the airbags off. This has caused a severe rash/burn on my son's face and neck. The vehicle is now being totaled by my insurance company and forcing me to have to purchase a new vehicle and my insurance rates to go up. Three days later, April 9, 2026, a safety recall on the over-sensitive airbags was issued for this Odyssey. There were no other warnings leading up to this. Insurance has inspected the vehicle and deemed it a total loss. | Crash: No Fire: No Injuries: 1 Medical attention | Unknown |
| Apr 2026 | STRUCTURE,VISIBILITY/WIPER | rear tailgate window spontaneously shattered | Crash: No Fire: No | Unknown |
| Apr 2026 | VISIBILITY/WIPER | The outside mirrors had a recall for potential detachment. My driver's side mirror detaches sometimes even after the replacement. When I contacted Honda over this issue, they told me that they can't take my complaint and I should go back to the dealer which replaced it. | Crash: No Fire: No | Unknown |
| Apr 2026 | ELECTRICAL SYSTEM,FORWARD COLLISION AVOIDANCE | The radar is broken leaving all ADAS unusable in addition to no option to use cruise control. | Crash: No Fire: No | Unknown |
| Apr 2026 | POWER TRAIN,ELECTRICAL SYSTEM,FORWARD COLLISION AVOIDANCE | After being on idle on a stop light, when releasing the brake to go, warning on dash says "Collision Mitigation Warning" when nothing hit the car and I'm there's enough distance with the car in front and behind. The severity has increased now, after being idle, when releasing the brake, it now completely shuts off, dash says "Shift to Park", and can't go, unless I push the ignition button. Took it 3x for the same errors on dash, Honda said the 1st time it was low battery, battery was running on low juice and didnt have power to come back from idle, they changed the battery. Now they say they need to replace the starter after few thou$and$. I see online this happening to others too. I fear the car behind me, may rear end me, because I can't go, green light is on, but I can't move as I'm re-starting the vehicle after being on idle. Honda says my VIN is not part of the bad batch. It's happening more frequently and Honda said they were able to replicate. | Crash: No Fire: No | Unknown |
