NHTSA Complaint #11485633 — 2022 TESLA MODEL S

I was driving my Model S from Oregon to Texas, 14-16 Sep. The car was new, picked up on 31 Aug. I had the car in Autopilot when I was on the highway on the drive to Texas. In the first two days I had four incidents of "phantom braking" at highway speeds, as high as 80 mph. There was not a lot of traffic those first two days and the conditions were dry so there was little risk to others and the car stayed straight during the braking. However it's not hard to imagine scenarios where unexpected braking at high speeds could be a problem, such as during wet or dusty road conditions, driving into a high speed turn with other vehicles nearby, etc. The vehicle has not been inspected but the incident has been reported to the dealer and I am awaiting guidance.
