NHTSA Complaint #11454187 — 2022 TESLA MODEL 3

We took our first out of town day trip of about 400 miles round trip, mostly freeway driving, last week 2/19/22. I tried using Tesla Traffic Aware Cruise Control several times during the trip, and we experienced at least 3 episodes of the "phantom braking" that I have read about. On those occasions, the system abruptly sounded alerts and braked automatically while cruising at about 80 mph (speed limit 75). There did not seem to be any obvious reason for this braking on the freeway on two occasions. There was one episode on a two lane section of straight highway, cruising at about 70 mph, when a large semi truck/trailer passed us in the opposite direction, both of us staying in our lanes, when the TACC sounded alert and applied brakes abruptly. I am very reluctant to use this function now until Tesla resolves the issues involved. It is very disconcerting and potentially dangerous when these events happen. I did send a "bug report" to Tesla from the vehicle the day after this happened. No response as yet.
