NHTSA Complaint #11537335 — 2023 TESLA MODEL 3

I was driving on a rural, two-lane highway with no other cars around and with cruise control engaged. Without warning, the car decelerated suddenly and rapidly from about 60 MPH and continued to decelerate until I pressed on the accelerator pedal (at about 40 to 45 MPH) to stop the deceleration. It happened at least 5 times during a drive from Spring Grove, IL to Champaign, IL on July 7, 2023, between 10:30 AM and 2:00 PM. If there had been a car following close behind me it would have been very dangerous. I had the Basic Autopilot engaged with Traffic-Aware Cruise Control (but not Autosteer). Weather conditions were bright sunlight with a few clouds. The problem has occurred several times (at least 4 times) since then. The problem has not been reproduced or confirmed by a dealer or independent service center. I have not had the vehicle inspected by anyone. There were no warning lamps, messages, or other symptoms of the problem prior to the failures.
