NHTSA Complaint #11463450 — 2022 TESLA MODEL 3

I was using Tesla's Traffic Aware Cruise Control. I was traveling at approximately 75mph on a highway. There was a car approximately 6 car lengths ahead of me traveling at approximately the same speed. There may have been cars next to me on both sides. For no apparent reason, the Tesla braked and the speed was reduced from 75mph to approximately 35mph. I disengaged the Traffic Aware Cruise Control and accelerated back to approximately 70mph. My safety was put at risk because the car behind me had to slam on their brakes and I assume the car behind them had to do the same. This was dangerous for my safety and the safety of the people in the car(s) behind me. The vehicle has not been inspected. There were no warning lamps, messages or other symptoms prior to the issue.
