2023 TESLA MODEL S Vehicle Speed Control Problems

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using Full Self Driving Supervised and software version 14.2.1.25, the speed control no longer is available and has been replaced by speed profiles.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...

Experienced severe phantom breaking on [XXX] in route to Las Vegas at 70mph September 2024. In heavy rain, while windshield wipers set to auto...........wipers have stopped momentarily blinding the driver, a problem Tesla hasn't fixed on my neighbors 2019 Model 3. The stalkless design prevents safe use of turn signals, horn and gear shifts. Wife who only drives an ICE car can not safely operate turn signals, horn and gear shifts in my 2023 Tesla Model S. Camera system constantly renders 'Blinded' error messages halting Autopilot features. Tesla's resolution is to clean camera's before initiating Autopilot.

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.

This complaint is about difficulties with the horn sensor on the steering yoke under emergency situations. After 14 months of driving the car, I have these safety issues: 1) The horn sensor is difficult to find in emergency situations. It is a single, small area located farthest away from the right-hand rest position and touching it requires a long stretch with the thumb. When turning, it is easy to lose the orientation of the yoke and nearly impossible to find the horn sensor. (See #5 in the attached image). 2) The horn sensor is near the cruise-control button ("right scroll button"). The cruise-control button is raised and I have accidentally engaged the cruise-control on multiple occasions when trying to reach for the horn sensor. I would lift off the accelerator, expecting to slow down, but imagine my panic when the car speeds-up due to the accidentally engaged cruise-control. (See #8...

Car suddenly accelerated and crushed into shop in parking lot

3 separate times the right pillar camera and 2 times for all cameras: The car's computer lost contact with the cameras and could not reconnect. In 2023, Tesla changed from radar to camera sensing technology. All driving functions relating to car positioning and cruise/speed control were lost at those times. Twice the car was under cruise control so the car interpreted this as 0 mph and initiated emergency braking from 75 mph on an interstate highway. I was able to avoid the following cars hitting me only by instantly accelerating back to posted speed. Tesla has been very difficult to convince that this is a problem. They say that remote diagnosis is inconclusive. Since they go for "at home" service first, 3 separate service times were cancelled by them, and they will not allow a service appointment at their shop for further diagnosis. Warnings came up on the instrument display,...
