2019 Honda Odyssey: headlights failing or too dim

Filed Nov 7, 2026 · Driver assistance · NC

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.

When starting the vehicle there is a cascade of sensor warning errors that will keep popping up intermittently even pressing the ”enter “ button to dismiss them. The Crash Mitigation sensor has been reported several times to the local dealership and they have said that nothing is wrong with it. This behavior began when the van was still under warranty which has since ended. The main reason for this report is that I have no idea if there’s going to be any issues with it automatically braking and causing an accident or anything else such as not being able to dim my headlights, have no indication of other drivers being in my blind spots, lane assistance not working properly and the emergency brake not working properly. Aside from these issues is the fact that the errors keep coming up on my speedometer screen, blanking everything else out that is necessary information, to safely drive the van. The tire pressure sensors are also malfunctioning which is also a concern I brought up with my dealership and they refused to admit there were any problems with it. The crash mitigation sensor will create an error just from being in the heat according to the mechanic with the Honda Dealership and they wouldn’t repair it. This same issue has been happening to multitudes of other Honda owners who purchased their vehicles because of the promise by Honda that the multi sensor system was safe. This issue has, in fact, created an extremely dangerous situation for drivers and their families who rely on it each day. I’m therefore concerned about this situation and respectfully urging for an immediate recall of the affected Honda vehicles before people are killed by their products.

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.

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

​The multipurpose windshield camera module in my 2019 Honda Odyssey experiences an internal electronic/power failure (Diagnostic Trouble Code U3000-49) while driving. This failure triggers a cascade of warning lights across the dashboard, instantly and without warning disabling the entire Honda Sensing driver-assist suite—including Collision Mitigation Braking (CMBS), Lane Keeping Assist (LKAS), Road Departure Mitigation (RDM), Adaptive Cruise Control (ACC), and Auto High Beams.

We were backing up the vehicle and the children started playing around acting like they were pushing the vehicle. The rear camera showed they were on the back corners of the vehicle and I think also the rear camera. As I pulled away all the safety notifications started to appear - adaptive cruise control, lane keep assist, high beam automation and a brake system error. The vehicle was taken to the dealership in Richmond, Kentucky who advised that the issue was the front camera that is in the rearview mirror mount area. I asked how this could be the front camera when everything happened in the rear of the vehicle. They advised they didn't know how but that is what their code readers are recognizing as the issue. They also stated that they have several individuals reporting this issue to them each month but there are no recalls due to this. This seems to be a safety defect as I cannot see how children playing around at the back of the vehicle affects the 'front' camera in turn affecting so many safety items.

In August 202, the multipurpose monocular camera failed. My car is a 2019 Honda Odyssey EXL. I was not involved in any accident or incident that would have caused this to fail. When this camera fails 5 warning codes popup: collision mitigation braking system failure , lane keeping assistance system failure, adaptive cruise control failure, road departure mitigation and auto-high beams stop working. The dealer priced the repair at ~$2,100. Many reports are coming up with this failure and it seems driven by overheating of the camera module, a filed camera component, or other unknown reasons.

In December 2025, my multi purpose camera failed on 2018 Honda Odyssey EXL seemingly out of nowhere. There was no accident or incident that would have caused this to fail. With the failure of this system, my collision mitigation braking system, lane keeping assistance, adaptive cruise control, road departure mitigation and auto-high beams no longer work until this camera is fixed. The dealer has confirmed the failure and the repair is over $2,000 to fix by Honda. The component has not been inspected by police or insurance, just Appletree Honda in Asheville, NC. The warning lamps for all of the systems affected show up everytime I start the car.

The LKAS, ACC, AEB, Automatic High Beams, and other safety features that rely on the front camera all became inoperable for no apparent reason. The front facing camera seems to be the culprit. This is a known issue and Honda should submit a recall to replace the faulty camera.
