Adaptive Cruise Control problems of the 2019 Honda Odyssey - part 2

Front monocular camera failed for no particular reason. Very unsafe.

The camera in the front windshield went out. It has caused none of my safety features to work. Honda is charging $2,500 for the part and labor. It's ridiculous how many people are having the same issue. My van didn't even have 52,000 miles. Honda needs to fix this issue.

The camera assembly monocular (part 36160-thr-a81) is shorted out causing multiple safety system failures from collision warning, lane departure, emergency braking, etc. Confirmed by local mechanic and then Honda dealer (merrillville, in). I still have the part, not yet replaced. Quoted $2k to replace. While driving multiple warning lamps went off and cruise control disengaged. No signs of issues prior to this occurrence. Now none of the safety features related to the adas system work.

My Honda Odyssey does phantom braking once in a while. There are no vehicle in front of it but it still brakes. One time it brake till full stop from 40 miles per hour.

Main windsheild camera failed.

2019 Honda Odyssey began having intermittent display, that progressed to constant display, of multiple warning messages regarding safety features related to multiocular/multipurpose camera unit. Vehicle is unable to perform lkas, acc, lane departure assist, autobraking, etc. Honda dealership states this is a well known issue related to a faulty camera that has to be replaced to utilize these safety features. Without replacement, the vehicle display is overtaken by a recurring onslaught of warning messages making instrument panel difficult to view. The specific part is listed as "2019 Honda Odyssey - camera assembly monocular (rewritable) - Honda (36160-thr-a11)" and the error code is u3000-49.

When my car hit 40000 miles or so, I started getting all sorts of warning lights showing up when I turned my car on. Took my car in to Honda today, and they said upon checking it that the multifunction camera which is located behind the rear view mirror has stopped working. The car has 44,500 miles on it. It has been in no accidents. There seems to be no reason for such a part to just stop working (needing a $2500 repair to fix).

Camera has failed disabling all the safety features associated and also the cruise control.

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.

I am submitting this complaint to report a serious and recurring safety issue with my Honda Odyssey involving the front monocular camera system. After stopping for fuel and restarting the vehicle, 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 due to a failure of the front monocular camera. This failure occurred without warning and immediately compromised several critical driver-assistance and safety features. Based on my research and discussions with other Honda Odyssey owners, this is a known and widespread issue. Honda is aware that the front monocular camera is prone to failure, and numerous owners have reported identical symptoms and error codes. Despite this, no recall has been issued. The required repair involves replacement and recalibration of the front camera and carries an estimated cost of approximately $1,500, which places a significant financial burden on owners for what appears to be a known defect. More importantly, the sudden loss of collision mitigation, lane assist, and adaptive cruise control presents a clear safety concern, especially when drivers rely on these systems during normal operation. Given the safety implications and the number of reported cases, I believe this issue warrants further investigation and a formal recall by Honda. Owners should not be responsible for the cost of repairing a known defect that disables critical safety systems. Thank you for your attention to this matter.

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.

The multipurpose camera has an internal failure at 105 thousand miles. This controls the automatic emergency braking, lane keep assist, adaptive cruise control, lane departure warning, and more. This safety features such as emergency braking, lane keep assist, and lane departure warning are important safety features. All of these features help drivers avoid collisions by acting to correct or avoid collisions or accidents faster or earlier than drivers can react. The Honda dealership service department has confirmed that the multipurpose camera had an internal failure, but did not provide a reason and there was no inciting incident during driving or ownership that caused this. The Honda dealership service department has been inspected and diagnosed that the multipurpose camera had an internal failure. No, there were no warning lamps, messages, or other symptoms of the problem prior to the failure. They only appeared after the failure, and the failure happened without warning. The failure first appeared on July 7th, 2025.

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.

The front multifunction windshield camera module failed due to a hot day. The cruise control, lane departure, collision mitigation, and other advanced driver safety assists are completely non functional. These are key safety features for ourselves and others. It has been confirmed by technicians, and many other owners of vehicle this model and generation with the same problem. It hasn't been inspected by the manufacturer. Many warning indications came on during startup and all the systems stated above stopped working. They haven't worked sense. This same thing happened about 2 years ago on this same van. This is a very common issue with this vehicle model and year. The manufacturer needs to issue recall for it.

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.

Collision mitigation braking system (cmbs) my 2019 Honda Odyssey slammed on the brakes while traveling 70+ mph on a clear freeway. There was no warning and nothing in the road. I have also had issues with the braking warning light flashing for no reason while traveling down the roadway. I called the Honda dealership and inquired about the braking issues and was told unfortunately it can happen, especially if I drive on windy roads.

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.

I had 5 warnings appeared in the dashboard : -adaptive cruise control problem -lane keeping assist problem -collision mitigation system problem -road departure mitigation system problem -auto high-beam problem and the amber brake system light came on permanently searched the problem on google and reddit found many Honda Odyssey owners having the same problem which is a safety issue some people took their vehicle to the dealership and have been told that the windshield camera is causing these warnings to appear because the camera is overheated by the sun, and the manufacturer did not make the camera well ventilated to dissipate heat caused by sun light.

5 warning shows up.

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.

When I start the vehicle, I consistently get warnings for acc problem, lake keep assist problem, collision mitigation problem, road departure mitigation problem, and auto high beam problem. This occurs every time I have driven the vehicle for the past week. From cursory research, this issue commonly appears to be related to a failure of the camera module located next to the rearview mirror.

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.

The multi-purpose camera/millimeter wave radar has been diagnosed by a certified Honda service center as having an internal failure, disabling all advanced driver assistance systems from operating as designed. These systems include: adaptive cruise control, blind spot monitoring, collision mitigation braking, lane keep assist, road departure mitigation, automatic high beam. The failure of these safety systems has increased the risk of crash and injury to the vehicle occupants.

Warnings displayed: 1. Auto high-beam problem 2. Adaptive cruise control (acc) problem 3. Lane keeping assist system (lkas) problem 4. Collision mitigation system problem 5. Road departure mitigation system problem 6. Brake system warning (red brake light illuminated) dealer diagnostic: multipurpose camera malfunctioning. Costs $2218 to replace. This should be a manufacturer recall.

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

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 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.

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.

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.
