2019 Honda CR-V service brakes problems

“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…”

“This emergency brake happened multiple times during crossing train tracks. I’m not sure if the sensor was capturing anything there but the car stopped immediately. Two incidents occurred in the same street and was after the traffic light turned green. Two times I had vehicles behind me but thankfully nothing happened. I monitored the incident then it happened again crossing another train tracks. One time just happened while driving, I didn’t have no cars around me but the car just started breaking on me.”

“While driving with my 3yr old in the car multiple dashboard warning lights suddenly illuminated simultaneously (including the Check Engine light, Emissions system warning, and various safety sensor alerts). The vehicle experienced a sudden loss of engine power, rough idling, and hesitation upon acceleration, which created an immediate traffic hazard. I took the vehicle to an authorized Honda dealership service center. The diagnostic scan revealed a failure of the fuel injectors (with diagnostic trouble codes indicating a system too rich and cylinder misfires). The dealership service advisor informed me that this premature fuel injector failure is a highly common and widespread systemic defect with Honda’s 1.5L Turbo direct-injection engines, stating that their shop actively stocks these parts because they perform at least one of these replacements every week. This premature component failure at mileage (105,136 miles) is a severe safety risk that causes unexpected engine stalling or power loss while driving.”

“Car automatically hit the brakes for no apparent reason while going at 45 mph. There was no vehicle or any kind of obstacle ahead of behind. Also resulted in tightening of driver seat belt. No injuries. Vehicle was being operated by an authorized and licensed driver.”

“While driving my 2019 Honda CR-V across railroad tracks, the vehicle displayed a BRAKE warning and automatically applied the brakes even though there was no vehicle, person, train, or other obstruction in front of me. The braking occurred while I was crossing the railroad tracks and caused the vehicle to slow unexpectedly. I did not intentionally apply the brakes. I am concerned that the Collision Mitigation Braking System/automatic emergency braking activated falsely and could create a safety hazard, especially at a railroad crossing.”

“While driving at about the speed of 45 miles/hr. the car abruptly braked in the middle of the road without any vehicle or object in front of me. It was a scary situation because if there had been a car behind me, my car would have been rear-ended. This problem has neither been reproduced nor investigated by anyone. I have, in the past, noticed that occasionally the brake light on the dashboard would flash for a second and go off but did not affect motion or speed. I have not received any warning messages regarding the vehicle's brakes.”
