The camera sensor in my 2019 Honda Odyssey EX-L failed due to excessive overheating. The sensor reached extreme temperatures, leading to a complete system failure. As a result, the vehicle became inoperable. The failed component is no longer available for inspection as I was forced to purchase a replacement due to the vehicle’s dependency on it for proper function. The failure of the camera sensor created multiple dangerous situations: Loss of vehicle control: The vehicle lost acceleration functionality and automatically shut itself down, which could have led to a crash in traffic.Dashboard warning lights: All dashboard lights illuminated simultaneously, indicating a severe system failure. Fire hazard: The sensor was emitting extreme heat, creating a potential fire risk due to overheating electronics. Exposure to the elements: The sensor’s placement in direct sunlight likely contributed to its overheating, further increasing the risk of failure. Mandatory dependency on the sensor: The vehicle was rendered inoperable without the functioning sensor, leaving me without a safe means of transportation. A Honda dealership inspected the vehicle and confirmed that the sensor had failed due to overheating. However, they stated that the cost of replacement, installation, and recalibration would be my financial responsibility. The issue was evaluated by a Honda dealership, but no manufacturer action was taken to address the failure beyond suggesting an expensive repair. All dashboard warning lights illuminated simultaneously. Loss of acceleration control occurred before the vehicle shut down automatically. The sensor was emitting extreme heat prior to the failure. The issue persisted after restarting the vehicle—after a 10-minute cooldown, the vehicle restarted but failed again after 3-5 minutes.This malfunction was not only a significant inconvenience but a major safety hazard. The sensor’s location makes it highly susceptible to overheating.
2019 Honda Odyssey electrical complaints
Page 5 of 9: complaints 101 to 130 of 225, newest first, as owners wrote them.
Several warning lights turned on. Emissions system problem, transmission system problem, brake 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. Steering becomes really difficult, reverse and forward gives out and really hard to control vehicle. Not able to accelerate. This problem happened out of nowhere no issues prior to the lights coming on. This has been happening for the past 8 months i have to unplug the battery so the codes erase and the car starts driving normal then 2 days later they come back and car wont accelerate or would have hard time picking up speed I researched and other owners of similar vehicles have the same issues as mines.
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.
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.
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.
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.
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 warning lights turned on about 9. Emissions system problem, transmission system problem, brake 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. Steering becomes really difficult, reverse and forward gives out and really hard to control vehicle. Not able to accelerate. This problem happened out of nowhere no issues prior to the lights coming on Took it to Honda they said there was no problem and they had not experienced this problem before. This is about the fourth time this happens now did my research and other owners of similar vehicles have the same issues.
All the controls in my Van (cruise control, lane assist, auto break etc...) stopped working. I took the van multiple times and the reason they gave is its possible that the Camera stopped working. I replaced the front windshield with OEM through Insurance. I have a feeling this happened only after the repair. The issue goes away for some reason while driving and comes back again. So its not due to any Camera failures. This seems to be a problem for many Honda Odyssey
Water intrusion near rear tailgate control box. The circuit board was ruined by water and the automatic tailgate was at first malfunctioning and then would not function at all. The circuit board had to be replaced.
LKA; Collision Mitigation Problem; Auto High Beam; Road Departure Mitigation; Adaptive Cruise Control Dashboard has ALL of these lighting up. Dealer said it was a sensor issue. No accidents; well cared for vehicle just spontaneously started issuing these alerts each time the car starts and the duration of the drive. Due to all the warnings the driver isn’t able to see fuel range etc.
At the grocery store and trunk would not close. Warning on the dash says “power tailgate problem”. Stranded my wife in the parking lot until she was able to get in touch with me to tell her she had to close it manually. It’s very hard to overcome the actuators manually if you’re a smaller statured person.
Leak in roof rail seam causes interior water leak and fried liftgate opener. Known issue manufacturer is not willing to address. Recent class action: [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
Rear power tailgate module fried due to moisture intrusion. Trunk will not close. Lock stuck in closed position.
I took my van to the dealer and they told me that the sensor inside of the front mirror is faulty, causing the following lights to continue to cycle if the car is on: Adaptive cruise control problem (ACC); Auto high-beam problem (A); Road departure mitigation system problem; collision mitigation system problem; lane keeping assist problem (LKAS); brake system lights. I am unable to engage or disengage any of these systems, including when I am driving. This seems to be a major security hazard and I am aware of others that have experienced this with this exact year, make and model (across different packages) of Honda minivan. I just wanted to report this in case this becomes a major concern for other consumers.
All safety lights are on on the dash. No cruise control. Brake system lane mitigation ,etc. been told it’s possibly camera issues quote from Honda dealer of 2200.00 to hopefully repair. 5 yr old vehicle and they want me to spend that. I can’t afford that.
Out of nowhere... a bunch of warnings lights have appeared and disabled a lot of the safety features on the vehicle. Adaptive Cruise Control Problem Lane Keeping Assist Problem Collision Mitigation System Problem Road Departure Mitigation System Problem Auto High Beam Problem The car drives fine but the safety features do not work, along with the cruise control. This is a known issue for Honda and there needs to be a recall before someone get hurt!!!
All the advanced driver assistance system fails intermittently. This causes 5 different warnings to come on and all of the safety features to stop working. This is an ongoing issue that I had taken to the dealer for on numerous occasions with no remedy.
The power lift gate would not open with the button on the dash, the button on the door, or the button on the key fob. The only way I could open it was to crawl in the back of the van, remove the access panel for the lock mechanism, and use the lever to unlock the door. Upon troubleshooting the problem, it was determined that the power lift gate control module needed to be replaced. That fixed the issue, however Upon inspection on the old module, which is located inside the vehicle, behind the driver rear quarter interior panel, there was obvious signs the failure was due to severe water damage intrusion into the module.
My family and I had just gotten on the parkway and the car wouldn't downshift. I noticed the "Drive" light kept blinking and then the dashboard lit up with so many different warning messages. "Emmissions system problem" was the message that stayed on. All of a sudden the car started shifting on its own into neutral, while we were on the parkway. Thank goodness there was an exit approaching and we were able to get off before we were injured in an accident. I have been having battery issues ever since I got this car. Even when it was brand new, sometimes it just wouldn't start. If I wait a little bit, eventually it starts, but I have already had to replace a battery at 30,000 miles because of this. It has been happening again, but when I bring it to Honda and my mechanic, the battery is normal. After doing research, it appears there was a recall on the 2019 Honda Odyssey with an issue relating to the battery connection that causes that transmission to reboot while driving and shift on its own. Honda claims my car was not part of this recall, but this is exactly what happened to me, and I have a 2019 Odyssey. They have had my car for three weeks now and can't find answers to fix the problem. When I first brought the car in, they said the technician was finding "A LOT of stuff." Fast forward two weeks, and they called to say it's not happening anymore so they are ruling it an "intermittent issue" and to come get the car (not fixed). I told them I do not feel safe with my children in that car. I need answers. I contacted Honda Corporate who said that Honda told them the transmission fluid was the reason, and to start with that and see if it happens again. I asked them about that recall and they said "well your car doesn't come up with it." Is it just a coincidence that the same thing has been happening to my car? I asked if they were able to find out why the car doesn't start "intermittently" and they said, "no, it hasn't happened while here."
The Tailgate Control Module failed on three different occasion on my 2019 Honda Odyssey mini van causing the tailgate to fail to be opened by fob or manually. This was caused by water leaking through the roof rail where there was a failure by the manufacturer to properly seal the area between the roof and body.I have two of the failed TCMs in my possession.On 2 different occasions the tailgate flew opened as I was driving at approximately 55 mph.At that time the tailgate could not be closed entirely and caused my battery to run down entirely.The problem has been confirmed by the local Honda dealership and another independent service center.A warning and beeping noice came on as the first sign of the problem.I have photos of the crack and what was done to try to remediate the problem.This problem has been recognized and occurred to many other owners of 2018 - present day Honda Odyssey mini vans.
The radio stopped working when looked into online it’s a known issue with the cords behind the radio coming loose on its own causing the radio backup camera climate control everything that that console is used for stops working the screen is black and does not come on after checking fuses the radio console is still out. with the cords coming loose on its own when i have no access to them honda should be held responsible for this repair.
The following message suddenly appeared one day and since then, they kept coming back on every time starting the car: ACC problem, Collision Mitigation Problem, Lake Keep Assist Problem, Auto High Beam Problem, Brake Problem, and sometimes Transmission Problem as well. After research online, many other owners of the same vehicle had the same issue and which may be caused by faulty connector or faulty front camera component for the hardware issue; or software issue which was on the previous recall for the multi-media issue on the Odysseys. There is a HONDA SERVICE BULLETIN 18-006 for the 2017-2018 CR-V models of the same issue/symptoms: [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
the front facing multi purpose camera is defective with a replacement cost of $1800-$2000. it controls all the lane assist, cruise control, braking functions of the vehicle
It is very common problem with 2018-2023 honda odyssey. Water leaks inside from the seam crack under roof drip trim. This water is dripping right on the tailgate control electronic module. And module is short circuit and dead. Now tailgate is either stays locked or stays open all the time as the latch is not operating at all. This is safety issue as if tail gate is not latched properly it can be open while driving on the road. Also with water leaking inside in trunk area it's a issue with growing mold under the carpet. It shows error message on instrument panel about trouble with tailgate system.
My vehicle would say mitigation control system failure, and would flutter by turning off and back on and making the vehicle in operable for a few seconds while in motion. Also, would have a transmission gauge issue and would make the car inoperable, and wouldn’t move at all, would only turn on and would function like the radio, lights, etc.
The multipurpose camera in the front windshield has failed, causing the adaptive cruise control, lane departure warning and correction, forward collision to fail. Even the non-ACC cruise control is locked out due to the failed camera. Honda will charge ~ $1800 to replace, and I can’t afford that. Problem confirmed by Ian’s of Broken Arrow. They confirmed it was the camera and not the radar unit. The failure of the camera causes a host of persistent dashboard warnings, but none preceded the failure.
The contact owns a 2019 Honda Odyssey. The contact stated that the driver's side rear sliding door failed to unlock while using the key fob, the door handle, or the door lock switch. There was no warning light illuminated. The vehicle was not diagnosed or repaired. The dealer and the manufacturer were not notified of the failure. The failure mileage was approximately 29,418.
2019 Honda Odyssey recently started having these problems intermittently, about 50% of the time I start the car: ACC problem Collision Mitigation Problem Lake Keep Assist Problem Auto High Beam Problem It prevents the front collision mitigation from working.
