2019 Honda Accord lane departure problems

I filed a complaint about this vehicle in october of 2020 when it was 5 months old at that time because it would slam on breaks and jerk the steering wheel for no known reason and with no one around. It has continued to do this intermittently as well as other erratic driving that cant be accounted for including at times getting confused when passing exit ramps where the car will slam on breaks and jerk to try to exit.

I was on the freeway going about 75MPH, when suddenly, my vehicle's cmbs system activated and slowed down speed to 20MPH approx. Without having any vehicles in front or near me. Luckily, the driver behind me was not following close and was able to avoid a collision by switching lanes. I have taken my vehicle to the dealer twice, but no one can find or duplicate the problem. Moreover, a couple of weeks ago, when I was switching lanes, toward the right, the left warning light and beeping noise came on.
