Water entered rear panel causing tailgate control module to get wet and stop working. This caused my tailgate to have no power and unable to close due to the latch being stuck in a closed position. Door was open unable to latch closed while I had to drive the vehicle to a mechanic.

While waiting at a stoplight, the auto idle system engaged and turned off the vehicle's engine. When attempting to continue through the intersection, the vehicle failed to start again. The only way to restart the engine was to place the car in park and push the stop/start button again. This caused a safety issue because I was in the middle of traffic at an intersection, and was expected to move. Thankfully the vehicle restarted without requiring any further intervention, and as a result the vehicle was not inspected by police or insurance representatives. This exact problem was previously addressed by Honda under a recall. During that time, they performed the software update as necessary, however that obviously did not remedy the problem. After returning my vehicle to the dealer, Honda has verified that my vehicle did experience this event and now says that it will need a new starter at a significant cost to me. I am dismayed by the fact that Honda Technical Service Bulletin 23-009 addresses this exact problem, including a warranty extension for a starter replacement, and yet is not applicable to the Odyssey model. There was no warning or indication that this incident was going to occur, and until the starter can be replaced, the only advice given by Honda was to disable to auto idle system (which must be done each and every time the vehicle is turned off/on).

 The contact owns a 2019 Honda Odyssey. The contact stated when driving 45 MPH, when depressing the accelerator pedal the vehicle merged independently to right side of traffic and then minutes later began to work a intended. Several warning lights illuminated. The vehicle was towed to the dealer where it was diagnosed that the battery needed to be replaced. The contact mention this failure has occurred on two different occasions. The vehicle was repaired twice for the same failure. The manufacturer was not notified of the failure. The approximate mileage was 66,500.

I keep getting a brake system light come on. Multiple warnings about the adaptive cruise control, lane keep assist, collision mitigation, and auto high beam. I used a code reader and it came back with code U3000-49 Multipurpose Camera Unit/Millimeter Wave Radar Internal Electronic Failure. I have seen multiple reports of this online regarding honda vehicles. Honda quotes repairs anywhere between $1500-$2500 to repair this unit. This should not be an issue on a car that is only 6-7 years old, 5-6 years old at the time the issue started. Given the seriousness of this issue and the amount of reports about this same issue online, a recall of this unit needs to be issued.

Either the ADAS camera or the radar sensor in the van is not functioning properly. The odyssey has know issues like the camera overheating and dies or the radar can be mis aligned by going through a car wash. We do not know which is not working in our van but we are now locked out of basic features on the van. The biggest problem is that cruise control no longer functions. I had previously turned adaptive cruise control (ACC) off and reverted the van to normal cruise control (CC). With the new issue, I al locked out of using CC even though it does not rely on the ADAS camera or the radar sensor.

Power Tail Gate electronic circuit is not working due to water seeping into the trunk from the Roof rails there is a manufacture defect with the sealants on the roof. Water seeping into the car is damaging the Battery as well as it had to be started with jumper cable.

The vehicle is showing persistent electrical and communication fault codes involving the ECM, ABS, and EPS systems, including P16E2, P16E5, P16E7, P16E8, U0401, and U0416. These codes return immediately, which suggests an active fault rather than a temporary low-voltage condition. The issue appears to involve the battery sensor and/or the related communication network between control modules. Because the faults involve ABS and EPS communication, the concern is that braking-related or steering-assist systems may not be receiving correct data. This creates a potential safety risk because the vehicle may experience intermittent or unreliable control-module communication, which could affect steering assist, braking-related warnings, or overall drivability. The warning lights and diagnostic codes first appeared before the vehicle was put back into normal use and have continued to remain present. The problem has been reproducible because the codes reappear right away after being cleared. No dealer or manufacturer diagnosis has been confirmed yet, so the exact root cause remains unresolved.

When those error codes appear, those safety features become unavailable during driving. These error usually come up when I just start the car.

Speakers, even if the audio is off, will produce a static sound, leading the center console to display a 'connection lost' message before going completely black. Screen will reconnect only when the vehicle has been restarted. Rear back up camera is affected by this as well by not working when the screen has lost network connection. Seems to be a FAKRA issue.

The monocular camera in the windshield failed and multiple warnings are present. It has been well known by multiple consumers the camera fails more often in the 2018 - 2020 Honda Odyssey.

The contact owns a 2019 Honda Odyssey. The contact stated that while driving at an undisclosed speed, several unknown warning lights illuminated and remained illuminated. The dealer was notified of the failure, but the vehicle was not repaired. The manufacturer was not notified of the failure. The contact believed that the failure was related to a sensor malfunction within the rearview camera. The approximate failure mileage was 114,000.

Issue: Intermittent infotainment failure – MOST network connection lost I am reporting a recurring electrical failure involving the infotainment system in my 2019 Honda Odyssey. The system intermittently loses all audio and displays a “MOST network connection lost” message. At times, the screen also goes black and reboots. This issue has occurred repeatedly over time, especially after extended driving (e.g., long trips). The audio will stop working completely, and the system may or may not recover after restarting the vehicle. Multiple repair attempts have been made, including replacement rear entertainment system. Despite these repairs, the issue continues to occur. Based on the error message and symptoms, this appears to be a failure within the MOST communication network, potentially involving the amplifier or related components. This creates a significant distraction while driving, as the system becomes nonfunctional and unpredictable. I am unable to access hands free phone capability and navigation features. I am also unable to access the heating and cooling features in the car when the screen is black. This has been happening since about one week after I purchased the vehicle in 2021. I am concerned that this may represent a broader defect affecting multiple vehicles.

On April 13, 2026, I brought my 2019 Honda Odyssey to a Honda dealership in Chicago, IL for a dealer-initiated recall service. The dealer contacted me and asked me to come in. Before the recall service, the vehicle had zero warning lights, zero error codes, and was operating completely normally. Immediately after the recall service was completed, the following warning lights appeared on the dashboard: Brake System warning, Hill Start Assist Problem, VSA (Vehicle Stability Assist) warning, and additional stability/steering system warnings. None of these warnings existed before the service. I returned to the dealership the same day. The service team cleared all error codes. However, within minutes of driving off the lot, all warning lights reappeared. This confirms the issue is persistent and not a one-time post-update self-check. I returned a second time. The service manager stated the warnings were not caused by the recall service and refused to investigate further. The dealer quoted 800 for diagnostic work. I also contacted American Honda by phone and was told they could not intervene. With the Brake System and VSA warnings active, the anti-lock braking system and vehicle stability control may not be functioning properly. This puts me and other drivers at risk, especially in emergency braking situations and on slippery roads. This pattern of multiple safety warnings appearing immediately after recall service on 2019 Honda Odysseys has been reported by other owners. The vehicle and its warning lights are available for inspection upon request.

Since January 15, 2026, our Honda Odyssey has experienced a persistent and unresolved infotainment system failure affecting critical functions, including the rear-view camera. The issue has been reported across three separate service visits (January 15, March 6, and March 26, 2026), during which attempted repairs—including wiring adjustments, battery replacement, and amplifier replacement—failed to resolve the malfunction. Despite escalating to a regional Honda engineer and multiple dealership interventions, the system remains inoperable, and the defect continues to immediately reoccur after each repair attempt. As of April 12, 2026, the vehicle’s infotainment system and rear-view camera are completely non-functional. The issue has persisted for 87 days, resulting in loss of use of key vehicle functions and raising significant safety concerns due to the inoperability of the federally mandated rearview camera (FMVSS 111). The repeated unsuccessful repair attempts and extended delay have led to the conclusion that the vehicle is currently unsafe to operate and has not been restored to a usable condition within a reasonable timeframe.

My infotainment system has gone completely black, resulting in the loss of several critical functions, including the rearview camera, AC vent direction controls, navigation, and radio. This has made reversing significantly more hazardous, and the lack of proper AC control is especially inconvenient during the summer. The Honda dealer performed a recall-related diagnostic, but it did not resolve the issue. After further inspection, they concluded that the infotainment unit has completely failed. However, they were unable to identify the root cause and recommended a full replacement at a cost of $2,850. I contacted Honda America to request assistance or a goodwill discount, but my request was declined. Due to the high cost, I have not proceeded with the repair. Although my vehicle is not currently on the recall list and has approximately 70,000 miles, there is a known history of infotainment system issues in Honda vehicles. A complete failure of this unit at this stage is unexpected and potentially related with their manufacture, as it is generally intended to last the lifetime of the vehicle. Thank you for your consideration

I was driving to work on April 7th, 2026 and parked the vehicle at my company parking lot. Prior to parking, I noticed unusual smell and then parked the vehicle. I parked the vehicle around 8.10 am and I got the call from my facilities manager around 8.30-8.40 am that my car caught on fire and by that time I noticed Houston Fire Department extinguishing the fire. There were no check engine sign and this vehicle is a brand new vehicle when I purchased. Though there is no recall associated with my VIN #, the fire issue is similar to recalls for 2019 Honda Odysey. The recall numbers are 23V-751( Engine Fire Recall) & 20V-066 ( Electrical Wiring fire Recall)

Both power sliding doors are malfunctioning, with the left side being critical. The dashboard intermittently flashes "Door Open" and "Left Sliding Door Problem" warnings during travel, regardless of speed or road conditions (highway, low-speed, and cornering). A certified Honda technician (Case #16203079) confirmed DTC B2037 is stored for the left sliding door ratchet switch. The diagnostic report explicitly states the rear latch is failed/stuck in the open position, resulting in a half-latched state that "CAN OPEN WHILE DRIVING." The right door also shows intermittent issues with the ratchet switch and pinch sensor. Despite this documented, life-threatening safety defect, American Honda has refused repair assistance. I have video evidence of the warnings flashing while in motion.

The rear portion of the vehicle is leaking water through the seams and cause major issues to the power tailgate control module. Water is infiltrating through either the seams of the trunk or side panels and right onto the module that controls the power tailgate. I’ve replaced the module at 95,000 miles, and now within 4000 miles is having the exact same issue. I can see water leaking inside right onto the electrical components that are behind the drivers side rear panel.

Multiple safety systems on my 2019 Honda Odyssey Elite have simultaneously failed, including LKAS, ACC, Collision Mitigation Braking System, Auto High-Beam Headlights, and other driver-assist features. The dashboard displays warnings for nearly every safety-related system, and the vehicle disables these features without warning. **Detailed Description of the Problem:** Whenever I start my vehicle, multiple error messages are displayed related to the Lane Keeping Assist System (LKAS), Adaptive Cruise Control (ACC), Collision Mitigation Braking System (CMBS), Road Departure Mitigation, Auto Headlights, and other safety features. These warnings appear together and persist even after restarting the vehicle. Apparently, this issue is widespread among 2018–2020 Honda Odyssey owners, with many reporting the same cluster of system failures. The problem appears to be related to a malfunction in the vehicle’s electrical system, sensors/ cameras, or control modules. In my case, the failures occur without any external damage, weather event, or driver action that would explain the sudden loss of safety functionality. When these systems fail, the vehicle disables critical safety features such as automatic emergency braking, lane keeping, adaptive cruise control, and automatic headlights. This creates a significant safety risk, especially at highway speeds or in low‑visibility conditions. **Frequency:** The issue occurs whenever the vehicle is started, affecting my driving everyday.

Five days after getting back our car from the Honda dealership where they “fixed” the two recalls all warning lights came on and not turn off. Steering, breaking, accelerating all are difficult. There were no issues prior to the dealership “fixing” the recalls. The car was just at our mechanic for brakes and they check our engine, fluids etc every time. There were no prior issues.

NHTSA ODI 11724402

I was commuting home, about 30 minutes into the drive, all of the dashboard and radio went blank for a few seconds. It came back on and the break light, anit-collision, lane departure, lights were all flashing. It did this 2 more times in the over the next 5 minutes. I was concerned for my safety because I wasn't sure if my breaks and all the other things were working propoerly. I didn't know how fast I was going or if my car was going to stall on the highway. I see that a recall was issued by honda yesertday, not for my car model, but a similar issue (a software bug can cause the instrument panel and rear-view camera to go blank). It has not yet been inspected by a repair person. There wre not any warning lights prior to this happening.
