Braking system caused my daughter to have an accident. My 2018 Honda Accord sport has been braking on its own for quite some time now. I attempted to turn off all safety features but somehow missed the braking system feature. The car will brake on its own with nothing in front of it. It will give beeping noises and flash "brake" on the dashboard. On 10/12/2022 my daughter was on the interstate, the roads were wet with heavy traffic. She called me saying that she had an accident. The officer stated that speeding played a part in causing the accident. My daughter said the car just started beeping and she noticed she was going to slow in traffic so she preceded to get in the right lane. Upon doing so she said that my car just started spinning and she took her foot off the gas and never applied pressure to the brakes. She ended up on the other side of the road hitting a guard rail. …

I was slowing down to pull into a parking spot at my office and suddenly the car accelerated, jumped the concrete barrier and crashed into the brick wall. The car continued to actively crash into the wall, so I put it in reverse and it accelerated backward with such force that it crashed into the rear of the car on the other side of the parking lot and then spun around 180 degrees and crashed into the side of that same car. My car was terrifyingly out of control. There was a woman in another car who had just parked and luckily she remained in her car because if she'd gotten out my car could have hit her. I don't know if this is related, but I regularly used the brake hold function and pressed the button to turn it off as I was parking. My perception is that the car suddenly accelerated when I depressed the brake hold button to turn it off. …
