Honda Odyssey headlights problems

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.

Front camera malfunctioning causing errors ACC, LKAS, Collision mitigation problem, road departure problem, auto high beam problem

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.

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.
