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.

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.

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.

- Falls Church, VA, USA

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.

- Fresno, CA, USA

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.

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.

- Atlanta, GA, USA

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 to hopefully repair. 5 yr old vehicle and they want me to spend that. I can-??t afford that.

- Plymouth, WI, USA

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!!!

- Skokie, IL, USA

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.
