1. Filed Aug 22, 2026Failure Jun 1, 2025San Francisco, CAElectrical system, Automatic emergency braking, Assist

   The 2020 Honda Clarity's multipurpose windshield camera fails intermittently, often at startup. The vehicle displays Brake System and Honda Sensing-related warnings, disabling Collision Mitigation Braking, adaptive cruise control, lane keeping assist, and road-departure mitigation. The vehicle may otherwise operate, but multiple driver-assistance safety systems are unavailable. A dealer attributed the issue to the windshield camera module and possible calibration. The warnings began approximately June 2025 and remain intermittent. The camera is available for inspection. No crash, fire, injury, or police report.

2. Filed May 12, 2026Failure Feb 2, 2026Rocklin, CAAdaptive cruise control, Warning, Assist

   The forward-facing multipurpose camera unit (ADAS camera) failed internally while driving, causing the simultaneous deactivation of multiple critical safety systems including Collision Mitigation Braking (CMBS), Road Departure Mitigation, and Lane Keeping Assist (LKAS). The failure is indicated by persistent dashboard warning messages stating 'System Fault' or 'Honda Sensing Problem'.A professional diagnostic scan confirmed DTC code U3000-49 (Multipurpose Camera Unit Internal Failure). The sudden and unpredictable loss of these automated safety features reduces the vehicle's ability to assist in avoiding collisions and increases the risk of a crash, particularly in emergency situations. This appears to be a widespread manufacturing defect in the camera hardware that poses an unreasonable safety risk to drivers and passengers.

   During a U-turn, when I turned the steering wheel my vehicle suddenly accelerated unexpected. I suspect there may have been a malfunction in the vehicle's electronic control system that caused this sudden unintended acceleration. I did alert Honda North America to study the problem. On [XXX], while driving on a narrow street at a speed of less than 5 miles per hour, my vehicle suddenly accelerated as I was making a U-turn. In my nervous response, I pressed the accelerator pedal, which exacerbated the situation and caused my vehicle to hit the driveway bushes at [XXX]   Fortunately, the property damage was minor, affecting only the bushes, and there were no injuries. I believe it is important to report this Sudden Unintended Acceleration problem for your file. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

   A/C stopped working, so defrost is no longer working efficiently. Honda says they only cover the condenser under the extended warranty and not the evaporator and want to charge me over 2200 to repair. If they are extending A/C warranty for condenser it should cover the entire A/C system since everyone online that had an issue with the condenser eventually ends up with an evaporator issue as well and then the defrost or A/C do not work properly.

   Engine RPM's rise (near red line at times) with little to no propulsion. The slang I've found used in online forums, showing that this is a common problem, is "angry bees."
