The adaptive cruise control and lane assist stopped working on my vehicle. Two alerts showed up on my dashboard. These features are important safety features with children in the car and the warnings are distracting and pose a threat to other safety features of the vehicle.
All my warning light come on every time I turn on the van. Been going on for several months. Was told the issue will get fixed if the front camera under rear view mirror get replaced. Feel like this needs to be recalled to get fixed, especially finding out Honda already knew there was a issue.
All this warning lights just come on out of no where due to the safety camera feature on the windshield that controls all the safety features of the car and this vehicles are not even 10 years old and the repair cost is too expensive for just that camera and almost every Honda odyssey is having the same issue I think there should be a recall for that specific camera in my opinion.
It started back in July 2026; I had a warning pop up that some functions aren’t available and to clean front windshield camera. We did. Still received the warning. Sometimes it’s there and sometimes it’s not. I can go down the highway and it will come up and then a few miles later it’ll turn off and the functions work. Even driving around town it does it. I have noticed there are a lot of drivers of the 2018 models having this same issue.
I own a 2018 Honda Odyssey Touring. On May 29, 2026, I started the engine on my Odyssey and several dashboard system warnings appeared. The internet suggested having the battery tested and it was getting low, so I replaced the battery. The warning signs remained and caused several Honda Sensing safety and driver-assistance systems to become unavailable, including Adaptive Cruise Control (ACC), Lane Keeping Assist System (LKAS), Collision Mitigation Braking System (CMBS), Road Departure Mitigation, and Auto High Beams. Additionally, a Brake System warning appears on the dashboard. I have video recording of these warnings from when they first appeared in May. On September 2, 2026, the lights disappeared out of nowhere and all components worked. Later that same date, the lights were back and the components stopped working again. This happened again on October 13, 2026 - lights went off, then returned later in the day. The recurrent temporary reprieve from the lights makes me wonder if there is an electrical short in the rearview camera that controls those safety features. The diagnostics cost of this alone was going to be nearly $200. As numerous other similar complaints have been made to NHTSA, I am hoping this issue will be investigated and addressed - it is concerning that a single system failure is causing multiple safety features to be disabled - notwithstanding that is is difficult to know when to be worried about warning lights when the dashboard is full of them.
The forward monocular camera mounted on the windshield of the 2018 Honda Odyssey Elite failed, and this single point of failure turned off the Collision Mitigation Braking System, Lane Keeping Assist System, Road Departure Mitigation, and Adaptive Cruise Control. A majority of the safety and assist features of the vehicle no longer work.
Front radar/camera failure.All yellow ADAS warning lights turn on simultaneously (Lane Keeping Assist, Adaptive Cruise Control, Collision Mitigation Braking System, and Road Departure Mitigation). Problem has been confirmed by dealer. Safety is at risk by not having this crash prevention features on.
there is a very common issue with Hondas that the front camera behind the rear view mirror shuts down which causes many safety systems to shut down and nit work this happened to my car it is very unsafe as i am now missing five very important safety features and i am going to have to pay thousands to repair it. This problem has been confirmed by my mechanic as he inspected it. This happened randomly out of nowhere with no signs of this coming. The five components that do not work because of this camera failure are lane assist, auto high beam, lane departure, adaptive cruise control, and collision warning. This puts me and others at danger.
The front camera that controls lane keep assist, adaptive cruise control, collision warning, auto high beam, lane departure failed so none of these features work. The component has been replaced by a Honda service center. I don’t believe the failed component is available to inspect.
Camera/Radar behind the rearview mirror failed. This triggered the following alerts to populate. Forward collision alert, auto high beams, lane departure, active cruise control (active and passive both failed to work), brake system, transmission system, lane keep assist failure. The gear indicator would flash when the transmission system error came on. Van has ~76k miles on it. ~$119 for diagnosis, ~$1400 for the part, ~$300 for the calibration and several additional hundred in labor. This is a known issue with the 5th generation Honda Odysseys. Honda won't do anything about it. It was up to 8 error messages on the dash at one point.
I own a 2018 Honda Odyssey Elite. On October 5, 2026, at 120,007 miles, an authorized Honda dealership diagnosed the vehicle with DTC U3000-49, Multipurpose Camera Internal Failure. The Honda technician cleared the DTC, but it returned shortly afterward. The technician inspected the camera and connector for poor connections or damage and documented that none were found. The dealership determined that the multipurpose camera needs to be replaced and reprogrammed. I was quoted $2,350 plus tax for the repair. The failure causes multiple Honda Sensing safety and driver-assistance systems to become unavailable and produces multiple dashboard warnings, including Adaptive Cruise Control (ACC), Lane Keeping Assist System (LKAS), Collision Mitigation Braking System (CMBS), Road Departure Mitigation, and related safety-system warnings. I have video documenting these warnings following the dealership diagnosis. My safety concern is that an internal failure of a single multipurpose camera can simultaneously disable multiple collision-avoidance, lane-assistance, and driver-assistance systems. I am reporting this failure so NHTSA has a record of the U3000-49 failure on my 2018 Honda Odyssey and can determine whether this represents a broader safety defect affecting these vehicles. The vehicle has not yet been repaired.
-multiple messages/lights on dashboard determined by dealer to be due to forward looking camera, which disables Hondas Sensing safety suite. Available for inspection upon request. -safety of myself/family and others put at risk due to distracting messages/lights on dashboard, which can also conceal additional issues not associated with forward camera. Safety features are disabled when the camera does not work properly, specifically lane assist, adaptive cruise control, collision mitigation , road departure mitigation, auto high beams. -problem has been confirmed by dealer: DTC U3000-49 -yes, inspected by manufacturer/dealership -issue appeared randomly approximately a month ago with no other warning signs
The front camera has failed so all of my forward driving safety features no longer work such as lane keep assist, adaptive cruise control and collision mitigation. Every time I turn on the engine I have multiple warning lights that appear every time that have to manually acknowledge to clear them from my dashboard.
Multiple warning lights on. Dealership told me it was code U3000-49 Multipurpose Camera mutimimillmeter wave radar internal electronic failure
All systems relating to the forward facing camera have failed.
This vehicle is actively immobilized on private residential property with its central ADAS safety networks and Advanced Driver-Assist networks completely crashed and offline (DTC U3000-49) and active short-to-ground circuit failures (DTC B2035) rendering the passenger sliding doors completely inoperable, creating an immediate entrapment and safety hazard. These progressive component failures cascade directly from severe environmental moisture intrusion inside the rear tailgate enclosure. This exact water migration vector intersects directly with active federal safety campaign NHTSA Recall 26-V-423 (Rearview Camera Failure), which isolates moisture intrusion into the panel housing as the root factory manufacturing defect. A manufacturer franchise location documented active water leakage onto the Power Tailgate Control Unit and heavy corrosion on the wiring connector under a previous Repair Order but performed zero interim moisture sealing, corrosion cleanup, or terminal mitigation, allowing progressive water migration to completely destroy the wiring system harness. Furthermore, American Honda Corporate Case Management explicitly stated on a recorded verbal line that the manufacturer is denying all repair assistance to remedy these cascading safety campaign electrical defects under an active corporate case. The manufacturer is in open default of its statutory federal obligation to remedy a safety recall defect free of charge to the consumer.
The contact owns a 2018 Honda Odyssey. The contact stated that while driving 25 MPH, the audio of the vehicle unexpectedly became inoperable. The failure was a recurring failure. Additionally, there was an abnormal burning odor inside the vehicle. The contact associated the failure with NHTSA Campaign Number: 23V431000 (Back Over Prevention); however, the VIN was not included in the recall. The dealer was contacted and stated that the cost of the repair was not covered because the VIN was not included in the recall. The failure mileage was approximately 90,332.
Front Molecular sensor/Camera
The windshield-mounted front monocular camera (Honda Sensing unit) overheated and failed/burnt out. This failure completely disabled the Forward Collision Warning, Automatic Emergency Braking, Lane Departure Warning, Lane Keeping Assist, and Adaptive Cruise Control systems, triggering multiple safety system warning lights on the dashboard.
Forward Collision Warning
The monocular camera (multipurpose camera secured under the rear view mirror) has failed. This disables the following" Collision Mitigation Braking System (CMBS): Detects obstacles or vehicles ahead and helps brake automatically if a collision seems likely. Forward Collision Warning (FCW): Works with CMBS to send visual and audible alerts if you get too close to a vehicle in front of you. Lane Keeping Assist System (LKAS): Adjusts steering torque to help keep your van centered in a detected lane. Lane Departure Warning (LDW): Alerts you if you drift across detected lane lines without using your turn signal. Road Departure Mitigation (RDM): Applies steering help or braking if you drift off the paved road entirely. Adaptive Cruise Control (ACC): Maintains a safe, set following distance behind a vehicle traveling ahead of you. These systems are helpful in keeping you safe while driving. The problem with camera failing cause these system warnings to populate on the dash. This is distracting. This has been confirmed with independent service center. Has not been inspected by manufacture. Started August 21. quoted $2200 to replace and recalibrate.
The contact owns a 2018 Honda Odyssey. The contact stated that while driving at an undisclosed speed, the accelerator pedal was depressed, but the vehicle failed to accelerate, requiring the contact to forcefully depress the accelerator pedal to move the vehicle. The contact stated that multiple warning lights unexpectedly illuminated, including the Road Departure Mitigation system, Collision Mitigation Braking System, and Lane Departure Warning system warning lights, and all related safety features failed to operate. The vehicle was not diagnosed or repaired. The dealer and the manufacturer were not notified of the failure. The failure mileage was approximately 105,000.
My Odyssey randomly began displaying all of the ADAS warning messages: The Brake System indicator light comes on, Forward Collision Warning, Lane Departure Warning, Lane-Keeping Assist, Auto High Beam System error, etc. These came on beginning 7/25/26 and have come on everyday since causing the entire ADAS system to be inoperable. There have been a few days that they didn't come on immediately. I have had a few days where they came on half-way through my drive. This is a safety issue due to a defect in either the front camera or wiring to it, a nuisance, and something Honda needs to correct. It seems to be way too common of an issue according to my research. There hasn't been any damage to the van and no reason for these to come on. I have done research and see this has happened to many people. The replacement camera is costly as well as the calibration. Therefore, I haven't taken it to the dealership but I have discussed the issue with them. They agree that the camera is getting too hot and failing, which is causing the errors and of course all of those safety features fail simultaneously.
Our van recently started flashing multiple warning lights every time we started it up. These include "Collision mitigation system problem", "auto high-beam problem", "road departure mitigation system problem", "lane keeping assist problem", "adaptive cruise control problem", and also alerts that there is an issue with our brakes. We took the van into our local Honda dealership and were told the ADAS camera was broken and would need to be replaced. We were told this would cost $2,733 and that there's a chance we will also have to replace the windshield (which is physically fine) for another $1200. The camera breaking is not normal maintenance or expected due to wear and tear. There is nothing physically wrong with our windshield, we have had no accidents, we have kept up on all needed vehicle maintenance. It's my understanding the location of the camera is simply causing it to overheat and blow out the electrical system. Additionally concerning is that even if I did have the money to fix the issue Honda does not have any cameras available. They are on backorder. It means as a driver to three small children I have to assume the nonstop alerts are all benign for at least a month. In the off chance there is a true safety concern such as brakes malfunctioning, I will not know as the alert system is going off at all times.
while driving at 35 mph a vehicle well ahead of me made a left turn exiting the roadway. My vehicle suddenly applied the brakes even though there was no longer a vehicle in my path. I tried to increase the accelerator, but the vehicle was slow to respond to this. luckily there was not another car directly behind me. This exact problem had occurred many time previously.
Higher-selling and older vehicles accumulate more reports. Counts are not failure rates and are not directly comparable between vehicles that sold in very different numbers.
