2020 TESLA MODEL S Vehicle Speed Control Problems

In all assisted driving modes except Full Self Driving (FSD), the car properly displays the speed Limit it has determined either by Map data or visual confirmation. In FSD, apparently only on pre-2021+ Model S cars, the determined speed limit is not displayed. In my town we have a US60 route. The car sees these signs and determines the speed limit is 60, even though it is only 35. The driver notices a rapid acceleration and may observe the set FSD speed has changed to 60. There is no Speed Limit displayed in this mode. Very dangerous to go this fast on a 35 MPH road. When not using FSD, the car does show this error in the speed limit as being 60, even though the car determined speed limit itself is in error.

From Aug 23 to 28, 2023, we traveled in our 2020 Tesla Model S Long Range Plus vehicle from Santa Fe, NM to San Diego, CA and back, for a total distance of approximate 2100 miles. We drove primarily interstates (I-25, I-10, I-8, I-5) where speed limits ranged from 55 to 75. We experienced numerous instances of what is known to Tesla owners as sudden, severe "phantom braking" [hereinafter PB] while the cruise control was activated (not AutoPilot, nor FSD, just cruise control). In ALL instances, no cars or other objects were visible within 1 mile ahead of our vehicle, and in ALL instances, these "phantom braking" incidents happened on absolutely flat, straight, smooth road surfaces, at all times of day, morning, noon, and night. This car has had PB problems since the day was purchased; in fact on that day, there were at least two sudden PB incidents while...

The latest tesla update has caused significant increased number of "phantom breaking" episodes when using just cruise control on state highways. I had at least 10 episodes on my last 100 mile drive (not using autopilot, just cruise control). Worst events caused rapid breaking from highway speed of 65 mph down to 40-45 mph with warning messages and audible alarms. Non of the events needed breaking. The worst two events were on straight sections of road with no oncoming traffic or other potential obstruction. I do not feel safe using cruise control on the freeway.

I WAS ATTEMPTING TO PARK MY TESLA MODEL S IN A CHARGING SLOT IN THE TESLA KETTLEMAN CITY SUPERCHARGE STATION. AFTER LOCATING A VACANT SLOT TO MY RIGHT, I MADE A RIGHT TURN INTO THE SLOT. THE CAR COASTED INTO THE SLOT IN A PERFECT HEAD-IN FASHION WITH NO PROBLEM. MY FOOT WAS ON OR HOVERING OVER THE BRAKE PEDAL, SLOWING AS NECESSARY AS THE CAR REACHED ITS DESIRED POSITION. ALL OF A SUDDEN, THE CAR LUNGED FORWARD WITH A POWERFUL PROPULSIVE FORCE. IT FELT LIKE WE WERE FALLING OVER A CLIFF OR ROLLER COASTER. I HEARD MY WIFE YELL FOR ME. THEN THE CAR CRASHED INTO A POLE IN FRONT OF THE PARKING SPOT. THE IMPACT CAUSED ALL THE AIRBAGS TO DEPLOY. MY FOOT WAS STILL ON THE BRAKE PEDAL TRYING TO STOP THE CAR. THE ENTIRE FRONT OF THE CAR COLLAPSED DUE TO THE FORCEFUL IMPACT. THE WINDSHIELD...

AS I WAS DRIVING, SUDDENLY MY SPEEDOMETER DECIDED TO STOP WORKING AND SHOWED 0MPH. IT HAPPENED TO ME TWICE ON SEPARATE OCCASIONS. REBOOTING THE SYSTEM FIXED THE ISSUE. I SPOKE TO TESLA SERVICE CENTER AND THEY TOLD THEY FOUND A FIRMWARE PROBLEM (THE SERVICE MANAGER TOLD ME IT IS THE 1ST TIME HE SAW THIS ISSUE) AND EXPECT A FIX SOMETIME IN THE FUTURE. TO MY QUESTION IF SPEEDOMETER COULD STOP WORKING AGAIN, HE SAID "YES, THERE ARE NO GUARANTEES IN LIFE. THE PROBLEM WILL BE SOLVED WITH THE NEW FIRMWARE." TO MY QUESTION WHEN, HE SAID "I HAVE NO CLUE" I AM UPLOADING A PHOTO AND ALSO HAVE A VIDEO
