NHTSA Complaint #11527902 — 2020 TESLA MODEL Y

While driving at highway speeds (50mph-80mph), on 2 lane or 4 lane highways, in the day or night, in sunny conditions and overcast sky's, while using the cruise control (auto-pilot), the car will suddenly and unexpectedly apply the brakes. It happens between 8 and 10 times on every road trip, each way. Not only is it a shock to me as there is never a visual obstacle that seems to be causing the hard braking, but it is a dangerous safety issue to other motorists too. This has caused cars behind me to take evasive maneuvers to avoid a collision. Other motorists have mistaken this hard braking as me "Brake-Checking" them and very nearly cause a road-rage incident. I've had the car for about a year and have opened several service appointments with Tesla. Each time they close the case before the service appointment with a version of the reply "this is normal" and "there is nothing to repair". They also claim that the car will learn how the react next time by my reaction to the incident this time. I have reacted the same way (by pushing the accelerator pedal until it regains forward motion) each time this has happened in the 8-10 times on each of the 6-8 road trips I've made in the last year. Clearly, the car isn't learning anything from my reaction to the sudden and unexpected braking. My safety is worth my time to make them take this seriously as they don't seem to be concerned with my safety!
