NHTSA Complaint #11483949 — 2021 TESLA MODEL 3

I was driving in Oklahoma on a straight interstate highway at 75 mph using cruise control (not autopilot) and experience a sudden application of full brakes. The application was so sudden the tires "chipped" and decelerated to below 45 mph before I could take control by applying throttle. On the same trip, I was near Midland, Texas and experience another serious phantom braking on a clear straight highway. By this time I experienced 10 additional minor braking issues. On my return trip, I did not use cruise control or autopilot and didn't have a single incident. I reported the incident to Tesla Service and reported ever incident via the feedback button (when it worked). I'm a retired Boeing engineer experienced in flight controls, fly-by-wire control, and aircraft subsystem design. I have no confidence in this design.
