Warning problems of the 2019 Honda Odyssey - part 1

The front monocular camera assembly (Honda part number 36160-thr-a81) on my 2019 Honda Odyssey elite failed and is available for inspection upon request. When the failure occurs, the vehicle displays multiple warning messages including “collision mitigation system problem,” “adaptive cruise control problem,” “lane keeping assist problem,” “road departure mitigation system problem,” and “auto high beam problem. ” as a result, several driver-assist safety systems are disabled, including automatic emergency braking, adaptive cruise control, lane keeping assist, and road departure mitigation, which reduces the vehicle’s active safety features and increases the risk of a collision. The warnings appear simultaneously on the dashboard while driving and remain active until the vehicle is restarted. The condition has been reproduced multiple times and has been confirmed during diagnostic inspection by a service technician. The camera failures are very common and are a design defect. The design was changed in later years but there was not a recall for the 2019 models. This is a very expensive fix and should be covered by a recall.

The car has started giving warnings every time I turn it on (as of 6 months ago): adaptive cruise control problem, collision mitigation system problem, auto high beam problem, lane keeping assist problem. It seems there must be a fault in the windshield camera that renders all these safety features useless. The repair shop stated that windshield camera isn’t working and is a $2k or more to repair. I am now driving a minivan that doesn’t have many important safety features and this is very dangerous.

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

Warning lights stay on for: 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. Lights will not clear. Dealership diagnosed for replacing monocular camera on front windshield/mirror. Gary smith Honda replacement cost $2364 on 20jan2026.

The front camera that is responsible for adas suddenly died and it is very vurnerable to heat. The unit gets very hot and it gets hot quickly. The lifespan of the unit is very short and the dealer is asking for $2000 to replace it like they have seen this pretty often.

Our front camera on windshield failed at 96k miles, causing all lights to come on the dash. This resulted in all safety features failed and even basic cruise control doesnt work. Lots of Honda owners have same issues and the result is that it is a failed front camera which could cost around 2k to replace. There is no other way around it. It is found out that the camera could over heat leading to failure. This issue should be a recall because it is a safety concern. Could you please look into it? thank you for your time.

While driving down the road way the collision mitigation warning failure flashed and then pulled the steering wheel pulled me off the roadway and nearly caused me to crash.

Driving on the interstate with cruise control. All of a sudden the car braked (no one in front within eye shot) and cruise control stopped. I had to tap the brake manually then accelerator to get the car back under my control. Ever since then I get acc, lkas and other warnings when the car starts up. It seems like the front camera catastrophically failed while driving and almost caused the car to come to a complete stop on the interstate. It was very scary.

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.

Multi-purpose camera unit internal electronic failure. Front-facing camera mounted in the windshield. This caused several warning lights including the brake system warning light to illuminate. This failure caused the automatic brake system and other safety features in the car to turn off. The vehicle has been inspected by a mechanic. There were no other warning signs.

Multipurpose camera failure, all advanced safety systems were affected (adaptive cruise, lane keep assist, blind spot warning, rear cross traffic warning, auto-dim headlights, etc) also, caused engine light, brake system and transmission system errors to appear but they were cleared by replacing the camera with no apparent damage to the actual systems. Replaced at a dealership for a total cost for parts and labor $2200+.

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.

The sensors in the rear view camera and the grille are malfunctioning causing my van to throw error messages for the adaptive cruise control, lane assist, automatic high beam and brake light to stay on. Theres a risk of accidents happening if the van doesnt notify the driver of lane departure at the right time.

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.

With no external cause the multifunction camera/radar stopped working at ~59000 miles almost immediately after we purchased it (used). Problem may have been disguised by dealer and occurred earlier. Oly fix is a $2000+ replacement. Automatic braking, cruise, lane keeping, collision alerts all disabled.

On random occasions all of the above warning lights come on. They will stay on for weeks at a time despite replacing the battery and following all reset protocol. It seems when weather is cooler, everything functions as it should and cam work fine for days and out of the blue will throw all the alerts again making lane assist, cruise control, and all departure assists not function. Because the system works sometimes and not others, the Honda dealership doesnt believe it is an issue with the camera or sensor specifically because it would never work properly. It isnt an obstruction issues as I make it a point to regularly clean the sensor area on the grill and on the window where the camera is. A strange thing I notice is it seems 5o work better on days that are foggy or raining where youd think there would be obstruction. Its just been a whole distraction while driving. I would be content at this point just to have those options not function ever but keep the orange blinking annoying lights off that decide to work randomly with no reason or rhyme.

While driving on the interstate (60-70 mph) in very light traffic (2 cars in view), there was a beep from the consol and the following errors flashed: adaptive cruise control, forward collision warning, lane departure warning, lane keeping assistance warning. At the same time as the beep the car felt like the breaks were being slammed on for 2 second. There was no car within 30 feet of us. And we went from ~70 mph to 40. This startled us. Ever sense then the errors would randomly come on and the vehicle will break suddenly, leading to very unsafe moments.

The front sensor has malfunctioned and all adas features are now disabled. There is no damage to the vehicle and was mentioned that this is a common issue yet no recall has been instituted yet.

Warning lights for collision avoidance, adaptive cruise control, and several additional safety features went on without any triggering incident. Brought to the dealership, where diagnosis is dtc u3000-49 multipurpose camera unit/millimeter wave radar internal electronic failure. Technician advised that this failure often happens after a few years for no apparent reason. Repair is upwards of $4000. Without repair, none of these safety functions operate.

Turned on the car the other day and several warnings displayed on the odometer. Adaptive cruise control problem lake keeping assist problem collision mitigation problem road departure mitigation system problem auto high-beam problem other than cruise controls not working, the car works fine. I took it to the dealer, and they said the camera module behind the rear view mirror needs to be replaced. Technician claimed that because my cruise control button was left on, it kept the camera running, and basically overheated the camera to a fault. He mentioned recommending to router owners that they only turn on the cruise control button when they plan to use it, and to leave it off if not. I asked if turning the cruise control button when not in use was referenced in the owner’s manual, but he was unsure. I would have to double check, but I don’t believe that warning is there.

Multipurpose camera is defective. The camera is available for inspection upon request. A number of safety features do not work when this camera is not operational, including forward collision warning and lane departure warning. Honda dealership performed a diagnostic and confirmed it needs to be replaced. No other parties have inspected the camera. There were no warning messages prior to the camera failing, only after it had failed. This appears to be a common issue affecting many owners of this vehicle.

I was driving the van and all this warnings came on my dashboard. Acc adaptive cruis control problem, lane keeping assist problem, collision mittigation problem. Road departure mittigation problem. All they come one after eachother on my dashboard. I did some research and a lot of vans 2019 have the sa e issues. My friend van same problem she payed 1900 to replace the camera. This is a safety issue and it cost a lot to replace. It cannot be deactivated. I hope it will be a recall issued for this model. I have 3 minivans Honda. I never had an issue with thjs brand . The new one is terrible. . . . Thank you.

Ton of warning messages. On the Honda online forum you can find hundreds of people with the same problem.

Without any notable prior messages or symptoms prior to the failure, on [xxx] after dropping off the kids at school and then turning on my 2019 Honda Odyssey ex-l (28,170 miles), the "brake system" light was on and the following 5 dashboard warning lights/messages turned 1) adaptive cruise control problem, 2) lane keeping assist problem, 3) collision mitigation system problem, 4) road departure mitigation system problem, 5) auto high-beam problem. The advanced driver assistance systems no longer works, and it becomes unknown to the driver whether the "brake system" light is being triggered only by the collision mitigation system problem, or an additional problemch as the anti-lock brake system not working. While no accidents occurred, the warning lights add unneeded driver anxiety, which can contribute to a potential safety impact. The problem has been confirmed by the san leandro, CA Honda dealer to be error code u3000-49. Dealer diagnosed problem as "multipurpose camera / millimeter wave radar internal circuit failure" and recommended to replace the multipurpose camera and perform aiming. Dealer advised that safety features will not work. The diagnostic fee was $179. 10, and the repair fee was quoted as $2456. 55 the vehicle or component has not been inspected by the manufacturer, police, insurance representatives or others. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

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

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.

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.

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.

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.

Front camera appears to have gone out in 2025. All safety features inoperable and constant flashing of warnings making it impossible to determine if anything is actually wrong. Collision mitigation failure, blind spot failure, transmission failure, brake system failure, blind spot. Those control etc. Honda has confirmed its issue with front camera.

It first started with the power tailgate failure which I brought it to Honda who are aware that there is a faulty sealant that is causing water to get into these Odysseys. They refuse to fix the issues and they are very costly. My van has never been in an accident. Now I'm getting all sorts of warnings from the adas system. Honda has refused to fix their issues and I can not afford $7000 cost to get this cleared up. People who own these vans are complaining and no one is doing enough to get this recalled.

The warning for these adas keeps coming on without any reason.

Multiple errors show up on the dash. I was told it’s dealership, but this is due to a failure of the multipurpose computer in the car. This is the issue that keeps recurring across all their cars of this type that has this unit.
