2018 Honda Clarity Plug-In Hybrid Forward collision avoidance Problems

“No Accident occurred but wanted to report a problem with my vehicle. Dealership diagnosed my vehicle with a malfunction in the multipurpose camera unit/millimeter wave radar. Because of this malfunction, my vehicle lost all its driving assistant abilities such as: Adaptive cruise control, forward collision warning, land departure warning, lane keep assistance, and automatic emergency braking. Attached a picture of a screenshot of my cell phone showing all the things that are affected by the one camera malfunctioning.”

“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 caused the unintended acceleration and concerned that others could be injured. …”

Very fortunately, no accidents occurred. …”

“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 to be the part that failed based on the attached EDR report. The odometer read 34,219 at that time. …”
