Honda Clarity

To Whom It May Concern, I am the owner of a 2018 Honda Clarity, and I am submitting this complaint to request that the National Highway Traffic Safety Administration (NHTSA) investigate what appears to be a widespread defect involving the front camera system used by Honda Sensing. My vehicle has experienced a failure of the front camera system, which has disabled numerous critical safety features, including: • Adaptive Cruise Control (ACC) • Automatic Emergency Braking (Collision Mitigation…

Here is an update to the issue I had raised with your office in March-April 2026: Honda Van Nuys performed the 35,000-mile routine maintenance on the Honda Clarity on February 24, 2026. At that time, Honda Van Nuys recommended (and I approved) that they clean the throttle. The odometer read 33,882 miles. I drove the car 337 miles when the unintended acceleration accident occurred on March 18, 2026 – 2.5 weeks after Honda Van Nuys cleaned the throttle. The airbags deployed. The throttle seems…

Currently the high voltage inverter is squealing, it is currently at the dealership. They have verified it is the inverter that is malfunctioning but they will not warrenty the repair because they are saying it needs to completely fail and throw a code. This is the right time to fix it prior to catastrophic failure, can you please help.

I am writing to report an unresolved high-voltage safety defect involving the Motor Power Inverter Module on my 2019 Honda Clarity Plug-In Hybrid. The vehicle's high-voltage hybrid propulsion inverter is emitting a severe, high-pitched mechanical squealing noise during acceleration and regenerative braking.The high-voltage inverter serves as the foundational link regulating current between the lithium-ion battery and the electric drive motor. A failing inverter module presents an immediate,…

I will first start with our problems/concerns. We had experienced a complete lost power in freeway speed (65 mph) when the battery is depleted, that is when the battery bar goes to zero bar instead of 2 bars usually. I attached a photo from the video I took for your reference. This experience was the engine ramp up and not getting any power while driving on freeway, escpecially obvious during uphill slope. It is a safety hazard where we had to manuver in order avoid traffic since we could not…

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…

Driver’s side sun visor increasingly hard to operate and finally broke internally due to high forces to adjust. Cannot use to shield driver’s eye from sun glare as intended thus reducing visibility. Passenger side also increasingly hard to operate but has not broken yet due to low use. Known problem for Hondas as indicated by TSB’s for other models and large number of videos on how to replace.

I was just driving normal and a message on my dashboard started to appear saying to clean my windshield or the collision mitigation system cannot work, We cleaned the windshield several times and it didn’t work the light still on, mow it got worst all of the lights turned on when I drive the car, adaptive cruise control light, road departure mitigation system problem light, lane keeping assistance problem light, collision mitigation system problem light and Brake system light, I checked…

I had an unintended acceleration happen as I was easing into a parking spot of a covered parking garage. The car accelerated like a jet plane taking off. I jammed on the brake. The only thing that stopped the car was the concrete wall that was 4 feet away. My airbags activated. We had taken the car to the Honda dealer for its 35,000-mile check-up on February 24, 2026. The Honda dealer has prepared all maintenance, including Honda recalls, since we bought the car in 2018. I'm scared about what…

The ADAS camera system failed causing multiple warnings and failures including lane departure system, forward collision system, adaptive cruise control and lane keeping assistance.
