| Jun 2026 | FUEL/PROPULSION SYSTEM | The high pressure fuel pump has failed on this vehicle. This is a known problem for vehicles between 2017 and 2020 and has not been adequately addressed by the corporation. | Crash: No Fire: No | Unknown |
| Jun 2026 | ELECTRICAL SYSTEM,ENGINE | Our vehicle has stalled at stop lights several times over the past 6 years. The auto stop/start feature seems to fail. The vehicle will shut off but when you repeat the brake it will not restart and the vehicle will die completely. You have to put it in park, wait a few seconds and try and restart. Additionally it has completely died at gas station after turning it off to refuel. When you go to start the vehicle it will be completely dead, zero power. We had to have it jump started. The battery has been replaced twice and was testing normal at the dealership. Not a battery issue. Honda acts like this is unheard of but our own research indicates it is a common well known problem with new Odyssey models. | Crash: No Fire: No | Unknown |
| Jun 2026 | ELECTRICAL SYSTEM | I am filing a complaint regarding recurring electrical and infotainment failures involving my 2020 Honda Odyssey EX-L. The vehicle experiences loud static and speaker distortion, infotainment system instability, static noises when turning the steering wheel, and intermittent key fob recognition issues requiring the key to sometimes be held near the start button. The issue appears to happen more often during or after rain or moisture exposure. The dealership has already repaired/replaced the FAKRA connector or related infotainment connector multiple times, yet the issue continues returning. The dealership recently witnessed the malfunction themselves and acknowledged the problem is still present. I am currently waiting for further direction from Honda technical support. This appears to be a widespread issue. There are many Reddit discussions and Honda owner Facebook groups where owners describe identical symptoms and repeated failed repairs. Some owners report having the same FAKRA connector replaced as many as six times with the issue still returning afterward. The repeated failure of the same repair raises concerns that the current remedy is ineffective and that there may be a larger electrical, wiring, grounding, or moisture intrusion issue involved. Because this problem continues after multiple repair attempts, I am requesting that NHTSA investigate recurring electrical and infotainment failures in Honda Odyssey vehicles and the repeated failure of the current repair solution. | Crash: No Fire: No | Unknown |
| Jun 2026 | ELECTRICAL SYSTEM | NHTSA Complaint Narrative – 2020 Honda Odyssey VIN: [XXX] Beginning in 2021, the vehicle experienced repeated starter and idle stop system failures, including: •delayed starting •failure to restart after idle stop •multiple warning lights •intermittent no start conditions •repeated battery failures The earliest documented complaint (Culver City Honda, March 25, 2021) states: “When using the auto start/stop feature the vehicle will have multiple warning lights. Sometimes will struggle to turn back on.” These symptoms continued for several years despite multiple dealer visits, battery replacements, electrical diagnostics, and software updates. In late 2025, the starter failed completely and required replacement at a cost of $1,890.25. The failure of the idle stop restart system poses a safety risk, as the vehicle may fail to restart in traffic after stopping at an intersection. Honda has refused to provide any written response regarding the issue. I am submitting this complaint so NHTSA is aware of the repeated failures and the potential safety implications.

| Jun 2026 | ELECTRICAL SYSTEM | The multipurpose camera unit /mil radar internal electric failure (DTC's U3000-49) caused the majority of the safety features lights to come on and eventually stalled out. This part has failed twice already. | Crash: No Fire: No | Unknown |
| Jun 2026 | STRUCTURE | Power tailgate won't stay open. It is a known issue (Honda service bulletin 22-018) and has tried to close while people are underneath - including my small children. I have knocked my head into it numerous times since the issue started. It almost always slowly closes, and sometimes it beeps a few times then closes automatically and if I'm under it I have to forcefully hold it open. A small child would not be able to. | Crash: No Fire: No | Unknown |
| Jun 2026 | VEHICLE SPEED CONTROL | Multipurpose camera is defective- broken after only 80,000 miles. No longer functions at all. No automatic emergency braking, no forward collision warning, no lane departure warning, no lane keeping assistance, no adaptive cruise control. Dangerous now without all those computer controlled safety functions. $2400 replacement. I don’t have $2400. | 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 | 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 | 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 | 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 | FUEL/PROPULSION SYSTEM | 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 | FORWARD COLLISION AVOIDANCE: WARNINGS | 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 | STRUCTURE:BODY | 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 | 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 | 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 | LANE DEPARTURE: BLIND SPOT DETECTION | 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 |
