Basically the warning lights and warning tone are showing and sounding off repeatedly when driving. My mechanic advised me that he has seen this issue on other Honda models and there is rumor of a recall. It has to do with the camera located in a housing with the rear view mirror. It is believed the heat here in [XXX] affects the solder abd causes all the safety systems to think there is a problem. The systems do still work, however you get constant dash board warning lights and warning tones. It is not an item that is caused by the owner neglecting maintenance and is estimated at between $1000 to $2000 to have it replaced. Honda should do a recall. It is a safety concern because it is a…

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.

The vehicle's Auto-Idle Stop (AIS) feature is defective and creates a severe safety hazard. While stopped at a busy road intersection, the feature engaged and shut the engine off normally. However, when releasing the brake pedal to proceed, the engine glitched and completely failed to restart, leaving the vehicle completely stalled, unpowered, and stranded in live traffic. The vehicle became a sitting duck in the intersection. This is a recurring issue that requires a complete ignition power cycle to recover, posing an immediate risk of a rear-end or side-impact collision. It happens most often under heavy load. Hot day with AC on, or Cold day with Heater on and seat warmers. Dealer ignored…

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.
