The vehicle's front-facing monocular camera experienced an internal component failure that triggered a permanent error code U3000-49. This hardware failure instantly disabled multiple core safety features simultaneously, including the Adaptive Cruise Control, Lane Keeping Assist (LKAS), Road Departure Mitigation, and Collision Mitigation Braking System (CMBS) ABS Braking and High Beam Support with all dash lights remaining on. The sudden, unexpected loss of automatic safety braking and driver-assist features while moving poses an immediate highway safety risk.

My Honda 2020 ridgeline has intermittent faults on the dash monitor, it displays ACC, LKAS, Collision Mitigation, High beam, lane departure warnings, and sometimes transmission problem. I am told it is the muti cable assembly sensor on the front window not communicating with the other sensors. I took my car to auto zone and they stated no communication, due to a bad battery. I replaced the battery, and it still has the multiple errors/ fault codes. During research several people have had this problem with Honda vehicles. At times it goes away for a day or two and then comes back with the same faults. It seems like a faulty part. The dealer wants 1800 for repair and calibration of sensors, this was after they ran a diagnostic test and found no engine faults/codes.
Problem started without warning. A couple of days ago all of these are disabled, warning lights scroll through on dash: ACC problem, Collision Mitigation Problem, Lake Keep Assist Problem, Auto High Beam Problem. It cleared once after restarting and once after service mechanic cleared codes. Issue returned the next day and continues. Built in safety features are not working. Deciding on having Honda dealer check it out.
Auto dimming/high beam feature flickers on and off intermittently at night without little relation to oncoming vehicles or dark highways. I have asked my local dealer twice to repair this problem, with no resolution. (see attached invoices). I also opened case with the manufacturer (Honda), and they declined to address my issue. I believe this is a safety issue because it is distracting to me and oncoming drivers.
Honda Ridgeline's "Auto High-Beam Headlights" do not work as advertised. They do not automatically engage high-beam headlights when appropriate. When this features rarely engages, the high-beams often disengage quickly - which distracts the driver and creates a temporary dangerous situation. I believe that this can be fixed with software.
Since this vehicle was purchased new the automatic high beams have not worked correctly and will often stay on for incoming traffic. There is no fix for this issue at the moment. Mentioned this issue to Honda Corp and dealership and never heard a response from over two years ago. Brought vehicle recently to other dealer and mentioned my vehicle still has this issue. They completed an unrelated software update. Needless to say my Ridgeline is still having this issue.
Since new vehicle''s Forward Collision warning stating "BRAKE" will occasionally appear for oncoming traffic. Vehicle has attempted to brake as well. There is no fix from Honda Motor Co. Vehicle also has an issue with automatic high beams (which has no current fix) which has been filed separately.
In winter weather driving the LED headlights become covered in snow and ice. I have to keep finding a safe place to pull over and manually clear the snow and ice off the headlights so I can see properly without dazzling other drivers.
Auto high beam feature fails to go to dim quickly enough when on coming traffic appears. Yet it will dim for white or yellow road sign reflections. The system is very unpredictable and causes people to flash me often. Recurring problem since new.
The Automatic High Beams on my 2020 rarely activate and when they do, they dim almost immediately after seeing their own reflection even on tiny road markers. Occasionally, they'll activate or flash oncoming traffic which creates a hazard to their visibility and my safety. I alerted my local Honda Dealership at a scheduled service but they stated their were no service bulletins in effect for the Automatic High Beam system, and therefore nothing they would do.
The automatic high beam function is erratic and has switched to high when on-coming traffic is approaching. It also switches to low when there's no on-coming traffic. This typically happens during highway travel.
