The vehicle suddenly braked on its own without any obstruction, causing a violent stop and injury. I took it to the nearest dealership to check for a recall. They said there wasn't a recall for this VIN, although online searches show this as a known defect for 2018-2020 Honda Accord Collision Mitigation System.

Wednesday 10/01/25 I was driving to work on the highway with cruise control on, it was a empty road with nothing in front or behind me, my steering wheel got yanked out of my hands and turned all the way to the right towards the guard rail, then the steering wheel got yanked all the way to the left automatically, I did a 180 degree spin and crash my 2019 Honda Accord Touring 2.0L. I believe the Lane Keeping Assist System (LKAS) was at fault as well as the Collision Mitigation Braking System (CMBS). The vehicle got towed off the highway directly to a local body shop. The vehicle is available for inspection upon request. Mine and others safety was put at risk because the vehicle decided to crash itself potentially killing me or other people. The vehicle just arrived at the body shop and no diagnosis has been done yet. The vehicle is not drivable so the problem has not been reproduced. Vehicle has not been inspected and looked into yet, I am waiting for the body man to do a deep dive into it or I am planning on bringing it back to the dealership. There was no warning lamps present.

The car brakes hard while your driving and there is nothing infront of you without warning and hurts your stomach with the seatbelt. Also when passing over a train track the car beside me went over it and the rail got detected and made the car stop hard.I was with my girlfriend and she is pregnant and the seatbelt got stuck for a moment and since it broke over the train tracks and the force made us fly forward and the seatbelts hurt our stomach but good thing there was no accident or anyone behind me

On Thursday November 16th at around 8:00 am I was driving down La Cienega Blvd going around 30-40 mph. I was about to pass a green light when my 2019 Honda accord sport started showing the brake signal on my dash. My car suddenly brakes and comes to a complete stop by itself in the middle of the road. There were no cars in front or on either side of me, no potholes or anything of that matter that would’ve caused this to happen. I am now suffering with severe neck and shoulder pain from this unexpected incident. My 1 year was also in the car with me. My car is now being inspected at the Honda dealership where it was purchased.

Emergency braking did not engage when coming up to a stopped car. Nor any of the warning lights or warning sound came on.

Travelling at approximately 47 mph, with nothing in front of me, the car's emergency braking system engaged completely unexpectedly, slamming my car to a stop. This caused a pick-up truck, to hit me from behind. The emergency brake light appeared at the exact same time as the car's emergency brakes applied. The driver of the other car confirmed there was nothing in front of me. The Honda dealer where I brought the car the next day stated there was nothing wrong with the camera or radar system. This failure caused an accident, and could have been much worse.
