NHTSA Complaint #11706639 — 2023 TESLA MODEL S

While operating my 2023 Tesla Model S Long range using Full Self Driving Supervised and software version 14.2.1.25, the speed control no longer is available and has been replaced by speed profiles. When operating the vehicle on Interstate 77 Southbound around Statesville, NC and on or about December 22, 2025, I set the speed profiles to standard in a 55 mph zone in which the Tesla recognized and displayed that it was operating in a 55 mph zone in Standard profile mode, the car varied in speed (with no traffic ahead) from about 57 mph to over 76 mph. This is highly unsafe and I had to repeatedly move back to Chill or Sloth mode at which time the vehicle strongly and unsafely braked causing cars behind me to close on me quickly and have to make strong and unplanned braking maneuvers to avoid hitting me. This was not the case when I bought the car and FSD when operating under 13.2.9. The removal of max speed control is extremely unpredictable and unsafe for me and those around me.
