NHTSA Complaint #11450012 — 2021 TESLA MODEL Y

I have experienced several instances of the phantom braking in my Tesla model Y. it primarily happens when I’m on a two-lane road and there is a large truck approaching on the opposite lane. However it will also phantom brake on a highway where there are two lanes going in one direction separated by a median with two lanes going the opposite direction. It seems to happen when it’s coming up on a slight hill, where you cannot see over the hill. The car will slam on the brakes in the middle of the freeway, which when going at speeds of 65 to 75 miles an hour when traveling with other vehicles going the same speed, it can be especially dangerous in Texas where the giant pick up trucks like to tailgate electric vehicles. In one instance the pick up truck behind me thought I was brake checking him and jamming on my brakes to be a jerk; he then “coal rolled” me, putting out a giant cloud of black smoke. This situation has made it so I am afraid to use traffic aware cruise control, which I need to be able to use on road trips. It is especially bad in the two-lane winding roads around Amarillo, Texas, but I’ve also had it do this on a much larger road that goes through Chandler, New Mexico to Colorado. I absolutely love my Tesla, but the phantom braking is concerning, and the response I’ve gotten from Tesla service is that the car adapts and will eventually learn where not to do it. I don’t know if that’s true or not, but it doesn’t seem to be getting better, and it does it at the same locations on the road. I need cruise control to be working. Another suggestion might be to have the ability to turn off traffic aware cruise control. I paid for full self driving but have not had the courage to apply to use it because of phantom braking. I would also like to see federal laws passed to address coal rolling of electric vehicles. It is extremely dangerous and it’s happening a lot in Texas.
