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+.
2019 Honda Odyssey driver assistance complaints

Front windshield camera failed and available for inspection if needed. All safety features tied to this camera are now disabled. Even basic cruise control is disabled. Problem has been check by a dealer with an estimated cost of $2600 to repair a simple camera module. Not inspected by police but was inspected by the manufactures dealer. I can get it inspected by the police if it helps. There are several warning lights that come up after starting the car. Even dinging when backing out of the driveway causing distractions. This is a known issue for this year Honda Odyssey van. There are lots of posts about it and how to try and fix it without the dealer charging you 10% of the cost of a 2025 model. For something designed for families this is not what I expected. This vehicles safety is impacted by the removal of these features.
Vehicle has code U3000-49 in the MCU module. All vehicle safety systems have shut down and are no longer working until vehicle is repaired (lane assist, collision mitigation, adaptive cruise control, road departure, etc.) Multiplex Camera Unit is on national back order with no ETA available. Vehicle has 5 warning lights and multiple messages that keeping popping up on the cluster.
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.
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.
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.
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
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.
The van's LKAS camera has malfunctioned. This has disabled not only LKAS but cruise control, forward collision warning, automatic emergency braking, blind spot warning, lane departure warning, and rear cross traffic. There is also a brake system failure light active on the digital dashboard. The failure of the LKAS camera has affected numerous Honda vehicles, not only the Odyssey, and across many model years. The part is available for inspection; #36160-THR-A81. The failure of the component has disabled key federally required safety features of the vehicle. The problem has been inspected by a Honda dealership. The repair cost is over $2,000. No warning lights nor error messages appeared before the failure of the component. It's demise presented as an intermittent error for 2 months before becoming permanent.
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.
In August of 2024, I started up my 2019 Honda Odyssey one morning and all the vehicle safety alerts/warnings on the dashboard came on (adaptive cruise control problem, lane keeping assist problem, collision mitigation system problem, road departure mitigation system problem, auto high-beam problem, ABS). I took the vehicle into my local Honda dealership and they ran a diagnostic which determined that the forward looking camera was faulty and needs to be replaced. There were previously no warning lamps, messages or other symptoms of the problem prior to the failure of the camera. The dealer's quote to replace the camera was $1,528.99 at the time. Having since researched this issue further on Honda owner forums, this seems to be a common problem with this generation of Honda vehicles. As evidenced by the corresponding warning messages, the failure of the front camera causes an array of vehicle safety issues impacting the driver and passengers, other vehicles and pedestrians. This defect, which is an extremely cost-prohibitive repair for the consumer, should be addressed and corrected by the manufacturer as soon as possible. The vehicle is available for further inspection upon request. Please note that I was unable to select all the applicable Advanced Driver Assistance Systems (ADAS) under the Problem Parts section of this form.
My radar and multipurpose camera need replacement
we were driving on the freeway when the car it stalled and place itself in neutral. we were unable to put it in park or drive. so we started googling while we were also trying to get a tow truck and we just decided to turn off the car and turn it back on and hoping for the best and we were able to put it back in drive and safely drive home definitely there’s a problem with the transmission or something electronical.
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
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.
Was Driving on my way to work and I heard a sharp sound while going up a hill. I then got warnings that said transmission issue, pull over immediately when safe and the car shifted itself into neutral. I was in the middle of traffic and lost all acceleration controls, while being forced out of the drive gear. I lost all speed and had to move through traffic and get to a side street. The same thing happened to me about a year and a half ago. It was covered by a warranty but I still was experiencing losses of car power or stalling.
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.
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.
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.
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.
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.
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 automatic emergency braking and forward collision warning will occasionally go off when there are no vehicles or obstructions in the way. It will often cause the vehicle to brake and make the driver act to keep the vehicle in lane or from another vehicle from rear ending you.
Warning for Lane Keeping Assist, Adaptive Cruise Control, Auto High Beam, Collision Mitigation, and Road Departure all populated at once. The functionality does not work, even regular cruise control without the adaptive feature. There have been many reports of this issue with fixes upwards of $3,000. Appears to be a faulty camera. This is a safety issue and should be addressed and recalled.
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
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.
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
5 warning shows up.
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.
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.
