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.

Adaptive cruise control problems by model year
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 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.
6 months after purchasing our 2019 Honda Odyssey we got warning that popped up about lane departure, collision and cruise control not being able to work properly. When we took it in we were told it was our front camera and it needed to be replaced and recalibrated. It would come to almost $3000 total. It has started to work for a couple of hours 3 times now. We bought this vehicle for it's safety features for our large family, not sure we will get another Odyssey after our issues with this one.
At approximately 52,000 miles, my 2019 Honda Odyssey Elite developed multiple simultaneous warning messages indicating problems with the Adaptive Cruise Control (ACC), Lane Keeping Assist System (LKAS), Collision Mitigation Braking System (CMBS), Autio High Beam and Road Departure Mitigation system.. with Break Assist light on. The vehicle was taken to a Honda dealership, where the problem was reproduced and diagnosed as a failure of the front windshield-mounted multipurpose camera used by the Honda Sensing system. The dealer recommended replacement of the camera and quoted approximately $2,350 for the repair, including calibration. The failure disables several driver-assistance and collision-avoidance functions at the same time, including adaptive cruise control, lane keeping assistance, road departure mitigation, and collision mitigation braking. I am concerned that the simultaneous loss of these safety systems could increase the risk of a crash, particularly if a driver is relying on the systems when the failure occurs. There was no collision or known physical damage to the camera prior to the failure. The warning messages appeared on the instrument panel when the malfunction occurred. The dealer has confirmed the camera failure. The vehicle has not otherwise been inspected by police or insurance representatives. The failed component is currently still installed in the vehicle and should be available for inspection upon request unless it is replaced during repair. I am submitting this complaint because a safety-critical camera component failed at relatively low mileage and simultaneously disabled multiple Honda Sensing safety systems. Worth mentioning, the rear camera system was recalled and was replaced given that failure and this camera failing around the exact same time I fear that this camera failed due to a manufacturing problem. The dealer confirmed that my rear camera was effected by the recall.
The front camera all of a sudden is malfunctioning - the following has been affected because of it: auto high beam, adaptive cruise control, lane keeping assist, collision mitigation system, road departure mitigation
My vehicle suddenly developed multiple warning messages at the same time, including: Brake System, Adaptive Cruise Control (ACC), Lane Keeping Assist (LKAS), Road Departure Mitigation (RDM), Collision Mitigation Braking System (CMBS), Auto High-Beam. The vehicle was taken to an authorized Honda dealership for diagnosis. The dealership determined that the front-view/multipurpose camera was short-circuiting/failing and needed to be replaced and calibrated. This concerns me as a potential safety defect because a failure of a single camera caused multiple Honda Sensing safety and driver-assistance systems to become unavailable simultaneously. I am concerned that the premature failure of the front-view camera may represent a recurring safety-related defect affecting other 2019 Honda Odyssey vehicles. A failure of this component can potentially leaving drivers without safety functions they may normally rely upon. Additionally, Honda Customer Relations told me that several customers had contacted Honda about the issue, and the dealership told me that it had replaced front cameras on numerous customers' vehicles for the same problem. I understand that Honda has issued a separate recall involving the rearview camera on certain 2019–2020 Odyssey vehicles. I understand that the rearview camera involved in that recall is different from the front-view camera that failed on my vehicle. I mention this only as additional context because both involve camera-related components on the same generation of Odyssey. I respectfully request that the federal safety agency review consumer complaints and other available information concerning front-view/multipurpose camera failure on 2019 Honda Odyssey vehicles to determine whether there is a safety-related defect trend.
Starting around 70,000 miles the front multipurpose camera continues to fail causing various warnings, including: - Collision mitigation system problem - Adaptive cruise control problem - Lane keep assist problem - Road departure mitigation system problem - Auto high beam problem
In January 2026, my 2019 Honda Odyssey (approximately 110,000 miles) suddenly began displaying multiple simultaneous warning messages on the dashboard, including Adaptive Cruise Control Problem, Lane Keeping Assist Problem, Collision Mitigation System Problem, Road Departure Mitigation System Problem, Auto High-Beam Problem, and a Brake System warning light. These warnings do not clear and are present every time the vehicle is started. As a result, the following safety systems are completely disabled: Forward collision avoidance / automatic emergency braking — the vehicle no longer detects or warns of potential frontal collisions Auto high-beam headlights — no longer switch automatically Adaptive cruise control and lane keeping assist — inoperable Road departure mitigation — inoperable In addition to disabling these safety systems, the persistent warning messages significantly obstruct the main instrument cluster display, making it difficult to see basic driving information including speed, fuel level, and odometer/mileage. This is a serious distraction and visibility concern in itself, separate from the loss of the safety systems. I have not yet had the vehicle professionally diagnosed, but based on extensive research into this issue — including reviewing the federal safety agency complaint database — this appears to be a widespread and well-documented defect affecting 2018-2020 Honda Odyssey vehicles. The pattern matches hundreds of other complaints describing failure of the front-mounted Multipurpose Camera Unit (MCU), frequently associated with diagnostic trouble code U3000-49 (Multipurpose Camera Unit/Millimeter Wave Radar Internal Electronic Failure). Other owners report repair costs in the range of $1,500 to $2,600 for camera replacement and recalibration. This represents a serious safety concern: a single component failure disables the vehicle's primary collision-avoidance and driver-assistance systems simultaneously, while also obstructing basic instrument cluster vis
Front camera failure causing all system errors to not work to include lane keeping assist, adaptive cruise control, lane departure warning, auto high beam.
2019 Honda Odyssey Ex : Sensing camera located behind front windshield failed and stopped working and giving bunch of error messages. Cruise Control and other saftey features operated with help of this camera stopped working. The part number is 36160-THR-A11-M1
The vehicle’s front camera/Honda Sensing system has failed, causing multiple safety features to become unavailable simultaneously, including forward collision warning, collision mitigation braking, lane departure warning, lane keeping assist, adaptive cruise control and related systems. The failure produces multiple warning messages and disables safety systems that the vehicle was equipped and marketed with. This is a recurring issue reported by other Honda owners and is currently the subject of a proposed class action lawsuit, Jones et al. v. American Honda Motor Co., Inc., Case No. [XXX]. The lawsuit alleges a defective front camera system affecting 2018–2025 Honda vehicles, including the Odyssey. I believe this constitutes a safety defect because the failure can occur unexpectedly and simultaneously disables multiple driver-assistance and collision-avoidance safety systems. I am requesting that the federal safety agency investigate this issue and require Honda to issue a safety recall and provide a free repair.
