When driving normally, oncominng traffic is triggering the frontal collision warning system. Is some cases long enough to start the emergency braking procedure if I do not engage the brakes manually preventing the automatic emergency braking. This usually happens on curves in the road in typically right hand curves. This is happening on 2 lane roads at between 45 and 55 mph. Initiating and emergency braking at this speed could send my car into the oncoming traffic. I am concerned for my safety if I do not hit the brakes manually.

False forward collision warnings by model year
What owners say
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.
2020 Honda Ridgeline-Internal failure, multi purpose camera. Multiple lights on dashboard and codes associated with driving support system, Collision Mitigation, Braking System, Lane keeping assist system, Road departure mitigation, Transmission System error. All these are showing up because of the front camera going out due to overheating. Dealership quoted $1197.20 for replacement. Multiple safety violations making vehicle unsafe to drive. Extended warranty will not cover.
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.
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.
Engine fails to restart after Idle Stop engaged. Engine stops normally when brake pedal is pressed and vehicle comes to full stop. Brake pedal is then released to restart engine but the engine does not start. Dashboard says "Shift to Park". The transmission is shifted to Park and then Start button is pushed to restart engine. Sometimes the Start button has to be pushed multiple times to restart engine. This is a safety issue because the vehicle cannot move in traffic, crossing an intersection, etc. It is equivalent to an engine stall. This happens approximately 10% of the time when the Idle Stop is engaged. Also, sometimes the engine will start but after a hesitation or a struggle to start. In this situation, "Collision Mitigation System Warning" displays on the dashboard. This happens probably 25% of the time. Battery and starter have no problem starting the vehicle outside of these conditions.
