2019 Honda Odyssey Complaint Log

My radar and multipurpose camera need replacement

Front camera stopped working, which appears to be a common problem for honda, and deactivated all safety features that rely on camera.

Nine simultaneous, spontaneous errors while driving in town. Error messages were as follows: * Emissions System Problem * Brake System Problem * Transmission System Problem * Brake Hold System Problem * Power Steering System (EPS) Problem * Vehicle Stability Assist (VSA) Problem * Hill Start Assist Problem * Road Departure Mitigation System Problem * Blind Spot Info System Problem

Shortly after owning we started noticing sporadic jerks between 24-29 mph that felt like a hard up shift. We immediately brought to our local Honda dealership where they performed a software update. We were told that the vehicle struggles to shift while under load. Recently our van was making a whining noise and seemed hard/delay to accelerate in drive as well as reverse. Almost felt like I was in neutral, but was not. NO warning lights were on, but something was not right so I went home. The next day it would not start and lit up every warning light. We had it towed to the dealership and was told battery was shot so they replaced. On way home it was still hard to accelerate so we brought it right back to the dealership and have been told a new transmission is needed. We have had all maintenance done at dealership prior to this. In fact, the vehicle was just in 3 weeks ago for an oil change and everything looked great. These issues have occurred without any warning lights or diagnostic alerts, making them unpredictable and dangerous. A transmission should not fail without any particular warning to the driver. It seems these transmissions have had a defect from the date of manufacturer that cause malfunctions, premature failing, costly repairs, and most important major safety concerns. Honda needs to be held accountable.

Took the van to the dealership to fix a recall for the fuel pump. A few days later, error messages popped up saying there are problems with the adaptive cruise control, collision mitigation system, lane keep assist system, and brake system, among others. I test drove it from Arcadia to Pasadena on both the freeway and the sidestreets without any problems. We took it back to the dealership who assessed it and told us that the multipurpose camera was bad. It would cost us $2100 to get it fixed. We refused. No one was hurt, however, the dealership told me that there is a safety risk to my family if I did not repair it. Attached is the invoice for the last visit during which the dealership gave us the estimate for replacing the multipurpose camera.

Got my windshield replaced. Was recalibrated. Within 3 months, 5 dash lights come on. 1. Adaptive Cruise Control Problem 2. Lane Keep Assist Problem 3. Collision Mitigation System Problem 4. Road Departure Mitigation System Problem 5. Auto High-Beam Problem And the Brake System light is on. I was told it wasn’t the new windshield and that recalibration wouldn’t fix the problem. The code that won’t clear is U3000-49

Forward multi purpose camera failed and cause the rest of the advance driver assist systems to malfunction.

The power sliding door on the passenger side failed to operate properly. After receiving a recall repair related to the sliding door, the door stopped functioning correctly, directly after I picked it up—it would not close or latch fully. The door assembly and motor mechanism are still on the vehicle and available for inspection upon request. 4-5 months later the driver side (same door) that was malfunctioning now will not close, I had to bring the car in for the 3rd time and they said the Pinch Sensor is bad and want $812 dollars to fix it. I have had the car from 2019 with no issues at all with the door. They claim it has nothing to do with the recall. I filed a goodwill form and they denied the claim. How was your safety or the safety of others put at risk? The sliding door will not close or latch securely, which poses a safety risk while driving, especially with passengers or children in the vehicle. The malfunction could cause the door to open unexpectedly or prevent the vehicle from being secured properly. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes. The issue was first noticed immediately after the dealer performed the recall repair. I had to return the next day, and the dealer temporarily restored operation. However, the same issue reoccurred about four months later, and the door is now inoperable again. Yes. The vehicle was inspected by an authorized Honda dealer both during and after the recall repair. No police or insurance inspection has been conducted. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? No warning lamps or dashboard messages appeared. The problem first appeared immediately after the recall service was completed.

The adaptive cruise control, lane keeping and road departure system randomly fails and does not work.

My power liftgate ceased to open or close via any electronic means (button on dash, button on remote, tailgate left button on back of vehicle). The tailgate control module in the rear driver side panel was full of water when it was removed. The circuit board back side was covered with moisture damage which has shorted out the board.

Recently got a message on the instrument panel that says "Emission System Problem" with DTC P219A. This is related to faulty fuel injectors. Honda released Service Bulletin 21-010 and extended the warranty to 10y/150,000mi to cover this issue. However, Honda is saying my VIN is not covered by this campaign. From browsing owners forums and talking to the dealer, it seems that many more owners are experiencing this same issue. Clearly the original service campaign did not cover enough VINs. Honda needs to expand the service campaign to cover more VINs to capture all of the faulty fuel injectors.

The contact owns a 2019 Honda Odyssey. The contact stated that upon starting the vehicle, the messages "Emissions system Failure", "Brake System Failure", "Brake Hose System Failure", "Power Steering Failure", "EPS Failure, "Vehicle Stability Assist (VSA) Failure", "Hill Start Assist Failure" and "Road Departure Mitigation System Failure" were displayed. The vehicle was taken to the dealer, where it was diagnosed that the fuel injectors had failed and needed to be replaced. The vehicle was not repaired. The manufacturer was informed of the failure, and a case was filed. The manufacturer referred the contact to the NHTSA Hotline to file a vehicle safety complaint. The failure mileage was approximately 120,000.

LKAS, ACC, Collision Avoidance, Auto High Beam Problem - all these dash lights come on due to unknown reasons. Dealership blames the windshield camera but even when replaced same issue happens. This is a major safety concern and is a frequent issue amongst 2018- 2025 Honda odyssey owners. It’s possible that the issue is electrical CanBus issue. Please help

The contact owns a 2018 Honda Odyssey. The contact stated while driving at an undisclosed speed, the contact drove over a pothole and the front passenger’s side curtain air bag deployed unintendedly. No warning light was illuminated. The vehicle was towed to an independent mechanic; however, the vehicle was not diagnosed. The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 100,000. The VIN was not available.

Upon starting the car, multiple alerts came on the dashboard reporting faults with multiple systems. There was no damage to the car, it had been parked safely and appropriately prior to starting. Dealership inspected the issue and reported the camera/sensor system in the windshield behind the rear view mirror is faulty. This faulty camera now causes multiple systems off line as the sensor is no longer reliable. This is a safety issue as this sensor assists with split second support to the driver to prevent collisions, leaving your lane or speed adjustment with cruise control.

BCM software is out of date or not programmed correctly, car turns off while driving. when park and off and the keys are away, car tries to turn on by itself. power lost while driving

8/10 times when turning on and driving the vehicle, an error pops up on the dash indicating the LKAS and ACC no longer work. Dealer found the code was U3000-49, they could not get it to clear. Sometimes the car will start without the problem, but then at some point through the drive it will occur and LKAS and cruise control will no longer be avaliable

The contact owns a 2019 Honda Odyssey. The contact stated that when the vehicle was turned on on several occasions, the "emission system problem, brake system problem, brake hold system problem, power steering EPS problem, vehicle stability assist VSA problem, hill start assist problem, and road departure mitigation system problem" messages appeared. The vehicle was taken to a dealer, where it was diagnosed that the fuel injector kit needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was approximately 120,000

The lkas and several other lights are on in the vehicle and no one has been able to provide any answers as to why. Nor can the problem be fixed. There is also a problem with the transmission. Upon acceleration there is a hesitation that the car will not engage

My 2019 Honda Odyssey has only 63,545 miles on it. The vehicle recently began making strange "rattling" sounds from inside the engine block when driving. I took the car into the dealership (Honda of Oakland) and learned from the technician that the rod bearings and/or connector rods are damaged. The engine needs to be completely torn down. To repair the car, I will need to purchase a new engine. The cost estimate is $13,000. Looking online, I discovered there is an ongoing recall for this issue affecting many 2018-2019 Honda Odysseys. Somehow, my vehicle has been excluded from this recall despite exhibiting the exact same problem(s) that the other recalled vehicles are experiencing. It appears that the existing recall parameters for the cars being affected by this bearing rod issue are too narrow. Many more Honda Odysseys are experiencing this same problem. I called American Honda for further assistance and they declined saying that the vehicle is outside of the warranty period and they are not obligated to help. I purchased this vehicle from the Honda of Oakland dealership - during my ownership, the car has passed many multi-point inspections. Nothing I have done (or did not do) has contributed to the problem - it is purely a manufacturing defect. The technician tells me that, if I don't make this repair, the engine could "seize-up" on the road while driving. This condition poses an active safety hazard for Odyssey owners.

LKAS, ACC, Collision Avoidance, Road Departure, Auto High Beam Problem, and Brake System - all these dash lights come on due to unknown reasons. New battery and terminal connections have good contact. Four safety features are now inoperative and no Cruise Control.

Transmission slipping randomly due to software issues

monocular camera failure. Diagnosed by Honda Dealership. Safety risk because the Adaptive cruise control, Auto high beam, road departure mitigation system and collision mitigation system no longer work properly. The warning lamps are continuously on the car, reporting this problem as well.

We were stopped at a red light the auto start/stop was enabled and the car stopped. The car turned off when attempting to start and I had to power down the car, open the driver door to reset the system and get the car turned back on.

The monocular camera went out unexpectedly for my van back in March 2025. I have multiple failure warnings that all of the van's safety features were disabled. The van had around 80k miles at the time and Honda dealer quoted me well over $2000 dollars to rectify the problem. Looked through forums and online groups and realized it was a very common issues with late model Hondas. Seems like the internal electronic is cooked by heat over time and caused the camera module to go out prematurely. I ended up buying a module from Honda and had an independent shop to calibrate it for the van which still cost me well over $1000 out of pocket.

The contact owns a 2019 Honda Odyssey. The contact stated that while driving at an undisclosed speed, the contact noticed an unknown message displayed. The vehicle was taken to the dealer, where it was diagnosed that the timing belt tensioner had failed and needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure and referred the contact to the NHTSA Hotline for assistance. The failure mileage was approximately 90,400.

Out of nowhere I received 5 warnings regarding Adaptive Cruise Control, Collusion Mitigation, Lane Keep Assistant, Automatic High Beam... etc Failure. Upon restarting the car, the warnings would clear itself on occasion but would reappear on following start up.

Water was leaking inside of the back driver side corner of the tailgate. The water built up inside of the PTG module and ruined it. The tailgate lock suddenly failed and opened up while driving down the road. The warning lamp illuminated that said tailgate error. No wreck just a sudden fail. i have video of the module pouring water out of it as i removed it from the vehicle.

A recall on December 18, 2023, covered the fuel pump on certain 2019 Honda Odyssey models. Mine was included. The problem has not been repaired because the dealer has told me several times that the necessary parts are unavailable. It has now been 15 months since the recall was issued. I am becoming increasingly afraid to drive this vehicle. Can you tell me how long I must wait?

Vehicle has hesitation when resuming forward drive after sitting at a light or taking left hand turn. The hesitation causes the feeling of not moving at the amount of speed the car should when starting to regain driving motion, then suddenly slams into gear and proceeds forward with a too quick acceleration to adjust to the amount of pressure applied to gas, causing the driver to have to hit brakes before hitting car infront of them.

This is my second 2019 Honda Odyssey that has Multipurpose camera unit internal electronic failure(error code U3000-49). Failed camera causing the whole ADAS system to stop functioning. This part shouldn't fail in 6 year old 50000 miles car. I will also report on my second Honda Odyssey which I had the same issue last year.

Water intrusion from driver side roof rack seal caused water entering the vehicle. Trunk underneath carpet wet. Power Tailgate stopped working and it was identified that the ECU (control unit) part number 74970-THR-A12 located behind the rear driver side trunk trim got water into it and corroded. Need to be replaced. Roof need to be re sealed. Further damage/corrosion from water which already was entering the vehicle unknown at this point.

The impact on the car is we no longer have cruse control (basic feature) and every time we turn on the car we see many warning lights turn on. Some other feature that does not work is lane assist does not work. According to what shows up to on the dashboard there are problems for "road departure mitigation system Problem", "Auto high-beam problem", "Adaptive cruse control problem", "Lane keeping assist problem", "collision mitigation system problem", "break system", "left sliding door problem" A quick search on the web indicate this a common issue with Honda car (including Acura). [XXX] Another problem we're seeing is driver Side sliding door does not close correctly or open correctly. We have since stop using this door since it's very dangerous for our kids since while opening, it would not open all the way and close on the kids. similar issues [XXX] These two things are broken under 65000 miles and less than 6 years owning the car.

Honda of America has released a warranty extension for "MIL comes on with DTC P0420/P0430, P030X, and/or P219A/B". My vehicle fits under the mentioned engine codes however, is deemed ineligible for the extended warranty. This issue with the faulty fuel injectors is a known issue that Honda has agreed to fix but is not willing to fix certain vehicles under the same warranty extension. This is a damaging part to the engine if left undealt with.

The power tailgate is not working, no fuse is blown, control model needs to be replaced, likely due to leak in back of car (happened after heavy rain). Looks like many owners of the same car have experienced the same issue.

When starting my van, I got warnings for ACC, Lane Departure, and Collision Mitigation stating that the issues were broken. I received error code U3000-49 at the Honda repair dealer which stated the multipurpose camera no longer works. In doing my research, it appears this is a known issue that Honda is not taking responsibility for and charging $1,500 to $2,000 to repair. They state the car works fine other than having none of those safety features working.

A number of warnings popped up: adaptive cruise control problem, lane keeping assist problem, collision mitigation system problem, road departure mitigation problem, and auto high beam problem. Only light that is on is my brake system light. I read a bit on some forums and it is likely to be the the front camera. Apparently the Multipurpose Camera Unit (MCU) fails often on these vehicles, causing these errors and the cruise control to stop working.

Dealer states that non OEM glass caused the front camera module to overheat due to overwork, currently broken and needing replacement. The glass that was installed was not EOM but IS made for front facing cameras so this seems very weird and sensitive. The replacement glass was put in two years ago but I am just now having this issue. Again, this doesn't seem to match their reasoning. Error code#U3000-49 2019 Honda Odyssey part: 36160THRA11 error messages. * Collision Mitigation * LKA * Adaptive cruise * Lane Departure Mitigation * Auto High Beam

When switching gear in low speed, car often jerk . Car also jerk when switching from reverse to drive froward gear.

The car is 2019 and has about 23k miles and the tailgate malfunctioned and is completely inoperable. Based on my visit to the Lou Sobh Honda dealer in Cumming, GA, I was told that there is a crack in the body that needs to be sealed and water from there caused the control board to be exposed and get "fried". this is not something I would expect to have a warranty. At least there should be some responsibility to get this fixed, first time for free or whatever. If the diagnostics is replacing tailgate module and reseal, I feel Honda should take some ownership on this. I have read online that many drivers have the same issue. When asked to Honda customer service, I was told there is "No campaign". If there is none, I want to create one. Have to spend 1000$s on a repair that has nothing to do with my driving or care is meaningless.

On 2/27/25 while driving my 2019 Honda Odyssey on the hwy the passenger side curtain airbags deployed after running over a pothole in the road. This frightened my wife and may it very difficult to see to pull over safely on the side of highway. There were no passengers in the car when it happened, no injuries or collision following g the deployment. We were very lucky. Police officer would not provide report because accident did not occur. Officer sated he had never seen airbag deployment cause by pot hole. My wife’s safety and the safety of others on the road that day were definitely at risk due to this unannounced airbag deployment. We did take to dealer and we were never given explanation of why it occurred. Damage caused by airbag deployment cost over $8,000 dollars in repairs and my wife still does not feel comfortable driving this vehicle. Now a year later we are experiencing electrical issues in the vehicle on the passenger side with power windows and locks. We feel that it is related to incident. Original Repairs were completed by dealer but they are now looking into electrical issues. There were no warnings or light prior to deployment.

Front camera went out which controls most of the safety features of the car.

The van stopped without any warning in the middle of a three lane highway. It could not be moved without a tow truck, We sat in a busy traffic lane at considerable risk. The Honda dealer that repaired the vehicle replaced the 06161-RLV-305 fuel pump. this was a very dangerous situation. The repair cost $1089.

I have had a recurring problem for years that the dealership has been unable to resolve. Occasionally while we are at a stop, and the engine auto off system kicks in, and then I tried to go again, the car stalls completely. Battery tests fine. It does not restart until sometimes after I open and close my driver side door a couple of times which I assume reboots the electrical system in some manner. The car then starts up again and is okay. This is extremely dangerous as it happens in the middle of driving down the road, and the dealership has been unable to identify a solution or what the real problem is.

Within 6 months of purchase (no accidents or related issues), the car starts firing off a wide range of alerts on the dashboard about failures. These include Collision Mitigation Braking System (CMBS), Road Departure Mitigation (RDM), or Adaptive Cruise Control, Auto High-beam problem, and Lane Keeping Assist problems. There are MANY reported issues like this online and it’s a clear failure of on Honda’s part to provide working safety features that they advertise.

Honda trunk area is soaking wet after raining, carpet is stinking like mold/mildew. From my research this is unfortunately a common problem and is not being addressed by Honda. This can cause major health problems for some, especially those who have certain respiratory diseases. Repair is pending on our van, but I feel we shouldn't be having to pay for a fix that should be being addressed already by honda as multiple vehicles/vans are defective

While driving at 25-30 mph, all of a sudden the 2 warning signs came up: “transmission system problem” AND “blind spot info system problem.” The “D” in the dashboard started blinking. When I put the vehicle in park at a stop light, the “P” also blinked. After a couple of minutes of this I pulled over and turned the car off. A few minutes later I restarted the engine and these warning lights have not come back in the last 5 drives. I read online that this may be a software glitch that needs updating (which I think is a manufacturer defect). I do feel like the car was a bit jumpy while these warnings were going off and I was TERRIFIED that it would put itself into park while I was driving and cause an accident.

The automatic engine start stop when at a stop while driving creates dangerous conditions. The engine stalls during the re-start and it seems to pull the voltage all the way down to where every controller is dead and restarting. Cycling ignition switch while cluster is black or restarting or throwing up bunches of fault messages as traffic is now moving and you are still stopped. Sometimes this re-boot process can take around 30 seconds (guessing, I'm freaking out during those moments so time is tough but it feels like a LONG time). I have not had an accident yet but definitely some very scary moments with wife and kids in the vehicle. This auto stop feature can be disabled but requires you hit the button with each ignition cycle and I don't always remember to do that. The Honda Odyssey currently has 80,000 miles on it, we bought it new in 2019 and this has been happening since it was new. We have had this reviewed at two different dealerships; there seems to be a dismissive attitude by the service departments. They have replaced batteries and there was a software update in early 2024 but this issue is definitely still present.

I have had the trunk struts and power module replaced twice due to water leaks into the compute module of my trunk. It has cost me headaches and thousand of dollars to have it fixed. This issue should be recalled to fix and for a reseal of the trunk. My dash has a power lift gate error show up and will not open anymore. Also it will not stay open as well and slowly just close itself.

All the symbols related ADAS suddenly popped in my car with no rain or snow or any accidents. When I checked with Honda dealership, they said it caused due to software issue and nothing related hardware and it needed 2500$ for replacing the entire system. If it is software causing this issue why would customer had to pay for it, and it could be a recall. I noticed similar issue for all 2019 and above models.
