NHTSA Complaint #11597062 — 2023 TESLA MODEL S

While driving west on [XXX] thru Utah at 78 mph (speed limit posted 80) the car suddenly and almost violently applied full brakes and reduced speed to 50 mph before I could override by applying added pressure to the accelerator. There were no cars in front of me for over a mile, and the following cars were well back as well. This occurred late morning on perfectly dry pavement. There were few if any clouds, the temperature was in the mid to high 90's. The highway was divided with a significant center divider. If there had been a person following me within 5 car lengths there would certainly have been a rear end collision. The location was roughly 20 miles east of Green River, Utah.
