NHTSA complaint #11766302

Owner complaint summary

I own a 2019 Honda CR-V and have repeatedly experienced brake-system warning lights, starting problems, a hard brake pedal and unexpected braking/deceleration. I repeatedly reported these concerns to East Coast Honda, asked them to inspect the brakes, and showed photos/videos of warning lights, but many of my complaints were not documented on my repair orders. While driving, my vehicle unexpectedly braked/decelerated when there was no vehicle immediately in front of me, causing me to hit a curb. This was in July. On 9/16/26 at 52,113 miles, East Coast Honda finally documented that the electric parking brake warning was going on/off while driving along with the brake-system and battery lights. They found DTC U3003-16, Brake Booster Control Unit Power Circuit Low Voltage, and replaced the electric brake booster. During the same repair, the dealer performed a Honda CMBS software update. Their repair order states that American Honda identified an ADAS/CMBS software condition in which “unexpected vehicle deceleration may occur.” After the brake-booster repair, the vehicle was returned to me. It then would not start and the brake pedal became extremely hard, leaving my young son and me stranded. The dealer documented that the battery FAILED testing and replaced it under warranty again. This is my second battery in less than 2 years. I am concerned that the underlying brake/electrical safety defect has not been resolved. The vehicle is available for inspection. I have repair orders, photos, videos and voicemail evidence documenting these problems.
