general problems of the 2019 Honda Odyssey - part 2

Multiple system problems constantly on my dashboard. Has brand new spark plugs and battery and problem is still there.

As I was driving the car computer showed overheating, brake failure, transmission failure and the car started shaking and the engine died. I had the car towed by triple aaa to a auto repair shop, but the next day when they went to fix the problem could not replicate it.

**vehicle:** 2019 Honda Odyssey **components affected:** forward collision avoidance, lane departure, adaptive cruise control, braking system, exterior lighting, electrical system, instrument cluster **complaint summary:** multiple safety systems on my 2019 Honda Odyssey 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, 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.

The computer system for the sliding doors and back hatch do not work properly. They will occasionally stop working or will stop mid-open or close. In addition, on three separate occasions the sensors did not work. One time the back hatch started to close while I was getting something out of the trunk. It did not sense by body and would not stop. I tried to stop it physically but the hatch continued to close. If I had not gotten out of the way, it would have crushed me. This happened to my husband on a separate occasion as well. He is athletic - [xxx} and [xxx] and was pushing up with all of his strength and the hatch continued to close on him before he had to jump out of the way. On the third occasion - the sliding side door started to close on my [xxx] as I was helping him into his car seat. This issue will kill someone. The 2019 Honda Odysseys need to be recalled immediately. I alerted my local Honda service center (don jacobs in lexington, ky). I asked them to notify Honda and they told me they wouldn't do that unless more people had similar issues. They have attempted to fix the computer system on several occasions and always say the issue is fixed. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

I am submitting this complaint to report a serious and recurring safety issue with my Honda Odyssey involving the camera system. Multiple warning messages and fault codes appeared on the dashboard simultaneously, including: -collision mitigation system problem -adaptive cruise control problem -lane keep assist problem -auto high beam problem these systems are all disabled. This failure occurred without warning and immediately compromised several critical driver-assistance and safety features. We have serviced at Honda dealerships and they said the only fix is a new $1500 camera (but the camera still works). Despite this, no recall has been issued. We have owned Honda vehicles for decades and never had these type of issues. A recall needs to be announced and owners allowed a fix at no charge. The transmission warning lights are also coming on intermittently and we paid to have Honda diagnose. The transmission is fine they said. Please help.

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.

Reporting a failure of safety recall 23-046 / NHTSA campaign 23v431000 on us vehicle. Post-recall 'remedy,' the vehicle suffers with the same most network error and from severe parasitic battery drain as described in Honda service bulletin 23-061. This led to a total electrical failure and vehicle grounding in -24°c temperatures. This systemic most bus network defect was previously the subject of the conti v. American Honda (2:19-cv-02160) settlement. The vehicle is currently grounded at a dealership in canada, and Honda canada refuses to acknowledge the failure of the recall remedy or the resulting consequential damages (battery/starter failure). I am filing this to report an ineffective recall remedy on a us-certified vehicle. I have tried establishing contact with Honda us however there has been no response from them.

Tailgate malfunction - unable to open and close tailgate. Warning message on dash states - tailgate power failure.

Vehicle was driving normally down the highway then proceeded to shutdown without warning. Suddenly all of the trouble lights appeared indicatinging engine, transmission, hill assist etc cut on without warning. The van would not drive above 55 mph when turned back on.

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.

Power tailgate problem is going off repeatedly while car is on. Power tailgate does not open with remote or button inside car. There seems to be water leaking in tailgate seams. The constant beeping of problem popping up is startling and distracting to driver.

I am the original owner of this vehicle and have performed all regular maintenance on schedule. It is our primary family vehicle and now over 120,000 miles. Since purchasing it new in 2018, the fuse for the horn has blown out several times each year. Most recently, the horn has stopped working, but the fuse remains intact. I am at a loss as to how to repair without taking apart the steering wheel which could damage the airbag. This is a serious safety issue as the horn is necessary to avoid accidents. I have spoken to the service department at my dealer and they are unaware of any recalls affecting the horn.

The contact owns a 2019 Honda Odyssey. The contact stated that while driving at an undisclosed speed, the vehicle suddenly shifted into neutral as indicated by the gear shift indicator light. The contact was able to coast to the shoulder of the roadway, where the failure persisted, and the vehicle was unable to shift into drive. The adaptive cruise control, lane keep assist, collision mitigation system, road departure system, and transmission fault detected messages were displayed. The vehicle was towed to an independent mechanic, who diagnosed a failure with the transmission control unit. The vehicle was not repaired. After investigating the failure, the contact related the failure to NHTSA campaign number: 19v299000 (power train, electrical system), but the VIN was not included. The manufacturer was not notified of the failure. The failure mileage was 133,000.

Something is wrong with the camera and causing all warnings to go off.

Read driver side power sliding door, got stuck halfway open. I've had this happen on the passenger side as well, but after turning the car off, putting power doors to manual, and rocking it back and forth, I got it fixed no problem and ended up having to replace a bump sensor on the door and it resolved. I thought that's what was going on when it happened to my driver side door as well. However after I turned the car off, and turned the doors to manual it still wouldn't close. I turned them back to automatic, turned the car back on, and the door proceeded to start going back, it rocked violently then broke the rear window and before stopping again. I read this track roller has been a problem for many users of this van and in some cases the entire door has fallen off because of it.

The forward facing camera has failed. A myriad of systems are dependent upon functionality of camera including collision mitigation braking, lane keep assist, lane departure warning, forward collision warning, cruise control, and automatic lighting and high beams. The failure also prompts a transmission system failure, though it's unclear how/why that system would be related. All issues are prompted by warning lights on the dash and the systems are inoperable. Research of the issue suggests it's a common failure across Odyssey and cr-v models with front-facing cameras and related safety systems.

What component or system failed or malfunctioned, and is it available for inspection upon request? passenger side sliding door not functioning while vehicle turn on. How was your safety or the safety of others put at risk? passenger on my vehicle can't exit out the vehicle in case of emergency. Has the problem been reproduced or confirmed by a dealer or independent service center? none. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? none. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? none.

My engine lights started flashing. I was stranded with my children. Had to coast into a nearby gas station. I’m told it’s a failed monocular camera causing all of it. When I google that it looks like it has happened to so many people! a recall needs to happen.

While traveling in my 2019 Honda Odyssey (40,000 mile) the vehicle completely shut off and placed itself into neutral. The warning lights for emissions system problem, brake problem, and parking assist problem lit up on the dashboard. The vehicle went into neutral and would not allow me to drive at all. Then the vehicle shut off all within 30 seconds. The vehicle would then not restart and now I have to get the vehicle towed to the Honda service department. After looking through other complaints there is a known recall for manufacturer defected fuel injectors for my year model Odyssey but does not appear when I search for recalls. This was an insanely dangerous situation here in oahu where the traffic is very bad. The vehicle gave no warning or check engine light and we have completed every service for the vehicle. The vehicle just randomly completely shut off and would not restart leaving my family of 5 stranded.

On our 2019 Honda Odyssey the passenger sliding door is failing to latch closed and stay closed or locked. The door is popped out in the back because the latch mechanism will not engage and electronically lock as part of the normal closing sequence like the other door. From what I can tell, this is the same issue reported in service bulletin 18-128, however when I called Honda about it, they said my VIN was not included in that recall. I am concerned because it seems like the same problem and it creates an unsafe situation where the door is not fully latching, even when manually closing the door and trying to lock it. I can hear excessive noise from that side of the vehicle, and the warning message flashed saying there is an issue with the right side sliding door, and the dome lights come on with an audible warning tone. I am unable to put passengers in the back of the van and needed to be very careful when driving it to the dealership for diagnosis yesterday. I'm still waiting to hear from them. I think this issue should be covered under recall work, since it seem like it is the same issue described in the service bulletin 18-128.

While accelerating from a complete stop at a red light, immediately after refueling, the vehicle suddenly lost all propulsion power and forced itself into neutral without any driver input. The dashboard lit up with numerous system warnings at once, including: •emissions system problem •brake system problem •abs problem •brake hold system problem •electric parking brake problem •vehicle stability assist (vsa) problem the engine won't start, leaving me stranded in the middle of an active intersection. I attempted to restart the vehicle multiple times with no success. Police responded to the scene, confirmed the vehicle could not be driven, and a tow truck transported it to a nearby Honda dealership. The tow truck driver suspected an alternator failure, but the dealer’s inspection the next day could not reproduce the issue. They reported that the alternator and battery “tested fine” and that no trouble codes were stored in the ecu. No repairs were performed, and no cause was identified. Safety concern: this incident created an immediate traffic hazard. The vehicle’s sudden loss of propulsion in traffic, combined with the inability to restart, could easily have caused a collision. Multiple critical systems were reported as failed simultaneously, indicating a possible electrical, fuel system, or control module failure. I am aware of similar complaints from other 2018–2019 Honda Odyssey owners in which sudden power loss occurred, often accompanied by numerous system fault messages. Many reports link these events to fuel pump failures, loose battery/ground connections, or transmission control malfunctions. This suggests a broader pattern of intermittent safety-related defects. Requested action: please investigate this incident and similar cases for potential design or component defects.

Sometimes the door locks will not lock, an obvious safety issue. I'm certain all the doors are closed and contacts are clean. I'm guessing a flakey relay because it doesn't happen a lot, perhaps 8 times in the past 12 months. I reported it to Honda America but they said the dealer has to verify it and the dealer has been unable to reproduce it.

Not sure if this is the right complaint form, but we attempted to have a service center address 2 recalls on our vehicle and they would not perform them and would not provide a reason why the recalls were not addressed. The service center is autonation Honda in westminster CO [xxx] ). We dropped our vehicle off on 7/24 for an oil change and to address the recalls. They said the work was complete on Monday 7/28 but would not provide an invoice of work completed. I've attempted to contact the service center by text and phone calls and they are not responsive. I contacted corporate Honda and they confirmed that the recalls have not been addressed. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

After two months of sitting outside in the arizona sun, the transmission was replaced on my 2019 Honda Odyssey. A day after picking it up all of the sensors came on. I have been informed that it’s an internal failure with the adas camera that’s housed in the windshield. After a brief web search, this seems to be a common issue related to electrical issues with the car. Since the electrical was connected and disconnected during the transmission replacement begs to reason that there was something faulty about this camera that didn’t make its way through the reset.

Majority of the time while driving you can hear static popping noises from the speakers. Sometimes it will degrade to not having any audio via radio, res, or phone connection. When it is in this state if placed in reverse, the backup camera will not function or display on infotainment screen.

Upon coming to a complete stop on the freeway, the idle engine feature stopped the engine. Upon letting go of the gas, the engine wouldn't restart and the electrical systems in the car malfunctioned showing a restart of the car would be needed. After trying to restart the car, the engine wouldn't turn over. After pushing the off button and starting the car again, it finally restarted. This created a hazardous situation as there was the potential for the car behind us to rear end us since we were at a complete stop on the freeway. After the software update, this happened again at a right turn on a local street.

Power tailgate failure. The power tailgate no longer opens and closes. There seems to be no cause for this. I have read, however, on several forums that this is a manufacturing defect and that rainwater is getting through the seal to damage the control motor. I cannot open the tailgate from outside the vehicle. This is a safety concern. There were no warnings leading up to this. I called my local Honda dealer to find out if there were any safety recalls, but there were none. I think there should be--this vehicle is only 6 years old.

My tailgate originally would not open and now the vehicle is inoperable. This was caused by a leak through the roof, where Honda failed to properly seal a seam, causing water to get onto the trunk control module and damage it. I see online this is happening with almost all gen 5 Honda Odysseys and is clearly a manufacturing defect, causing thousands in repairs for each.

The automatic emergency braking and forward collision warning will occasionally go off when there are no vehicles or obstructions in the way. It will often cause the vehicle to brake and make the driver act to keep the vehicle in lane or from another vehicle from rear ending you.

My 2019 Honda Odyssey’s power liftgate control model failed due to water intrusion. My liftgate started to open and close while I was driving, would close on me while loading/unloading the trunk, and would also open while parked in parking lots nearly hitting passing vehicles. It is truly a huge safety concern. Once the old module was out, I found extensive corrosion and rust on the module and its housing. As well, the entire bracket inside of the vehicle is rusted. There appears to be a defect in the manufacturers body seams that is allowing water to enter.

On a rainy day, the power tailgate began to malfunction. First it would open part of the way, beep, and then close, then when trying again it would go move back and forth on its own, and then close. Trying it again later, however, it completely stopped working to the point where we had to manually force it to open and close, only the latch would work. The heads-up display showed power tailgate error. On my attempt to troubleshoot I found that water had leaked into the area behind the driver's-side rear inside body panel where the rear control module and fuse housing is located, which I noticed was covered with water. I was able to partially dry this. Later on the rear tailgate started working again briefly but the problem returned and now it no longer works. I contacted Honda USA about this issue and they told me there is no recall for this, however when I did a google search this issue immediately pops up and seems to be a common manufacturing safety problem that has not been addressed.

I am filing this complaint to report a recurring and costly defect involving the starter system in my Honda Odyssey. The vehicle has been experiencing starter failures every few months, requiring repeated repairs and part replacements. Each time the starter fails, I am left stranded without warning, creating a serious safety hazard, especially when the failure occurs in public areas, on road shoulders, or during emergencies. The defect has caused extreme inconvenience, financial strain, and raised serious concerns about the reliability and safety of this vehicle. Given the frequency and cost of the problem, I believe this constitutes a systemic defect that should be investigated for a potential recall or manufacturer responsibility. I urge the NHTSA to thoroughly investigate this matter to determine whether this ongoing issue with the starter poses a broader public safety concern and qualifies for regulatory or enforcement action.

My radar and multipurpose camera need replacement.

The contact owns a 2019 Honda Odyssey. The contact stated that whenever it rained, water was leaking into the vehicle and caused the rear door circuit board and power module to short circuit. The contact stated that the rear door was inoperable. The contact stated that the failure was an ongoing issue which started a year after purchasing the vehicle new. The contact stated that whenever it rained the rear door failed to function normally. The contact stated that the vehicle was taken to the same dealer several times and the dealer was unable to duplicate or determine the cause of the failure. The contact had taken the vehicle back to the same dealer for the recent failure. The dealer diagnosed that water had entered the vehicle from the roof and had accumulated in the rear door near the electrical circuits. The dealer determined that the rear door power module and circuit board needed to be replaced. The vehicle was not repaired. The manufacturer was informed of the failure. The failure mileage was approximately 61,000.

We have multipurpose camera failure. No damage or accidents. It just started failing. There are many reports of this and the camera is on back order with Honda. They are charging $2100 to fix it. The official Honda Odyssey forum online has countless complaints on the same issue without resolution by Honda. Honda has acted in bad-faith towards their customers since this defect impacts the vehicle's advanced safety features for which buyers incur additional expenses, endangering the lives of passengers. Honda has acted in bad-faith towards their customers by designing a system that requires continuous and substantial expenditures without resolution because it is an engineering problem, I. E. , the placement of the radar behind the large, thick plastic h emblem obstructs the radar. I hereby ask that the NHTSA investigate this issue and order Honda to offer a solution in the form of a recall that permanent addresses the problem. Our experience after contacting Honda corporate to get some help is this is a money maker for them.
