Just starting the vehicle one morning all of these warnings appeared including adaptive cruise control problem, lane keeping assist problem, collision mitigation system problem, road departure mitigation system problem and auto high beam problem. We replaced the 12V battery thinking that was the cause but this did not solve the problem. We checked the fuses that were recommended to check and they were intact. We then did the 10 minute drive as suggested to reset these systems which also did not work. Then we used an OBD2 sensor to reset/clear the codes which also did not work, they immediately came back once the car started again.

What owners say
My 2019 Honda Odyssey, with approximately 93,947 miles, has developed an intermittent electronic braking and driver-assistance system malfunction. A yellow "Brake System" warning light appears on the dashboard, accompanied by warnings indicating that Adaptive Cruise Control (ACC) and Collision Mitigation Braking System (CMBS) are unavailable. A diagnostic scan identified trouble code U3000-49, suggesting a potential electronic control system malfunction. The exact defective component has not been confirmed. This is a serious safety concern because the vehicle's automatic collision mitigation and emergency braking assistance may unexpectedly become disabled, increasing the risk of a collision, especially during sudden braking or highway driving. The warnings occur intermittently without a clear trigger. The issue may involve a faulty camera, sensor, or electronic control module. The vehicle has not yet received a confirmed root-cause diagnosis from Honda. The vehicle remains available for inspection upon request. I request that the federal safety agency investigate whether this represents a widespread safety defect affecting 2019 Honda Odyssey vehicles.
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.
The contact owns a 2020 Honda Odyssey. The contact stated that upon starting the vehicle in the driveway, the automatic braking system, adaptive cruise control, auto hi-beams, and Lane Keep Assist warning lights illuminated, followed by a beeping sound, and the systems became inoperable. In addition, the multi-point camera was inoperable. The vehicle was taken to the dealer, where an internal failure of the multi-point camera was diagnosed. The vehicle was repaired. The failure mileage was approximately 83,300.
Over the course of 3 days, cruise control and lane assist systems would shut off and messages would display about adaptive cruise control, lane keep assist, lane departure warning, and collision avoidance system not working. Sometimes a transmission problem message would also become active. Sometimes the messages would be present at startup but other times the systems would show up green on the display and then the systems would shut off while driving causing the vehicle to suddenly slow down in highway traffic. The root issue seems to be a broken or malfunctioning multipurpose camera for the driver assist system. The camera has not been replaced yet to verify but related codes are active based on a code scanner and symptoms match what is expected for the camera failure. The vehicle is 6 years old with 99,400 miles at the first occurrence of the issue and does not have any windshield damage or signs of water leaking that would contribute to a failure. My primary concern is that the software completely disables cruise control when the camera for adaptive cruise and lane keep assist fails causing the vehicle to suddenly slow down rather than allow normal cruise control to continue operating and display the warning messages.
The front ADAS camera fails to work about 80% of the time, which gives me many warning alerts. My Honda mechanic said that it has a U3000-49 error code, which disables all primary driver-assist safety functions (CMBS braking, Adaptive Cruise, and Lane Keep Assist). This is clearly a safety hazard due to unexpected loss of active crash-mitigation tech. This problem has not caused me to be in an accident yet. However, because of this failure, the vehicle does not perform many of its expected crash-mitigation functions, which may contribute to a future collision.
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 the federal safety agency, 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.
Vehicle: 2026 Honda Odyssey EX-L, VIN [XXX] (leased). My prior leased Odyssey (2025) was totaled on [XXX], when its Lane Keeping Assist malfunctioned at highway speed: the steering became unresponsive, the vehicle drifted out of lane, and it crashed into a concrete barrier. I filed the federal safety agency complaint 11744403 for that incident. That complaint also documented Adaptive Cruise Control surging and a dealer visit that found nothing wrong. This leased 2026 Odyssey has a recurring Adaptive Cruise Control defect. After stopping at a red light with ACC engaged, a light tap of the accelerator to resume has caused sudden unintended acceleration, followed by a loud beep, ACC disengagement, and loss of propulsion. This occurred [XXX] ([XXX], rush hour traffic) and [XXX] (about 5:01 PM, [XXX]). On [XXX], the forward collision warning repeatedly alerted to a vehicle ahead when no vehicle was present. I brought the vehicle to Honda of Cleveland Heights on September 9, 2026 to report these issues; the dealer was unable to reproduce or identify the problem. Sudden acceleration toward the slow-moving vehicle ahead and unexpected loss of propulsion in moving traffic are severe safety hazards. The defect spans two vehicles, which points to a systemic Honda Sensing issue rather than an isolated fault. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
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.
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.
