2017 Tesla Model S Speed Control & Cruise Problems

Software 2025.14.1, Full Self Driving 12.6.4 (FSD). Vehicle when using FSD continuously slows to 10 MPH below the speed limit. You can manually press the accelerator to speed up but FSD will not brake when doing so and warns you of the same. After a minute of being back at the speed limit, FSD again slows down. Repeat this process constantly. Very dangerous.

Approaching my garage door as it was opening when the car suddenly accelerated smashing through the garage door, through the back wall of the garage, through the laundry room and finally stopped in the main bedroom with the front wheels off the ground as the car rested on top of the washing machine.

Since full self driving, beta has been turned on my car no longer slows down when I reduce the speed or when it encounters a lower speed limit sign, which it will read the speed limit. Prior to this when I decrease the speed or it noticed a decrease speed limit sign. It would use regenerative braking to slow the vehicle down. Now it’ just coasts , and actually sometimes maintains power at a high speed. There are times from going from a 60 and then to a 40 and then to a 30 mile an hour speed zone where it will continue to travel at 50+ miles an hour through the entire speed zone without slowing down which it did not do before FSD beta was active.I have to disengage the full self driving in order to get the car to slow down

The issue occurred twice over the period of the past two months, both times I was driving on highway with Tesla autopilot enabled ( It is Adaptive Cruise Control), for no apparent reason the car hit the brakes, all vehicles driving behind me had to hit brakes or change lanes to avoid Collision. Both times I created service request with tesla and got no clear answer to why its happening, first time I was told it is because the exit on map was about couple miles from car location so car had to hit brake hard and change lane to make it to exit but car never tried to change lane, it just did hard braking. 2nd time I was told it happened due to wheel alignment not being accurate. After wheel alignment was done I reached out to tesla again but so far they can not confirm or deny if tesla autopilot is safe for me to drive. I was told to use autopilot at my own discretion. Are car manufactures allowed to sell hardware or software without taking responsibility for its safety ?

-I think there is known problem with the Tesla. It autoaccelrates o behaves like someone is taking ove the control fo the car - The inital problem happend on June 24th 2022. I was in the parking lot of my work when It felt like I had lost control of the car to hit 2 parked cars. It cost severe damage to front of the car. Car was in the workshop for 4 months. This was completely unanticipated.I have hisotry of driving in US for over 20 years on major freeways before this without a single accident may have developed muscle memory( reflexes by repeated actions) in controlling the car. I was not distracted at the time. of note however my car had rear damages from being rear ended 10 days prior but Tesla authroized dealer had said it was drivable. The car was not in auto pilot mode - Tesla didnt give me any explanation and the repair workshop generalized saying it's usually driver's fault - Since the return from the repair I have 2 auto accelarations driving in the low speed zone. I had to break immediately to control it. Each time it felt like somthing remotely did this. There hasnt been recurrent damage. --The car was inspected by the Tesla authorized workshop couple of times and they claim nothing is wrong. -There have been no warning except on 04/15/2023 when it happened smewhere between 1.34 to 1.36 I thught I heard sort of noise/ quick warning. Again, each time it happens it feels like car is trying to do its own thing ( even when it's not in auto pilot mode)or someone is remotely doing it. Further info on my car: It was purchased in 2020 as a used from Tesla.This problem of auto accleartion or loss of control feeling did not start until car was rear ended in June 2022. I have security footage from the parking lot on how the car behaved in June of 2022 -

On numerous occasions the car, while on cruise control will suddenly, and for no reason brake. Sometimes very hard. The latest was today at 1336 MST.

ON 12/03/20 AT AROUND 9:57AM, AFTER I SLOWLY TURNED LEFT INTO A PARKING NEAR A WHITE TRUCK AND JUST ABOUT TO BACK UP INTO MY COMPANY'S EV CHARGING PARKING LOT THEN THE CAR SUDDENLY SPED FORWARD CLIMBING OVER THE CURB OF THE MEDIAN SEPARATING THE PARKING AREA AND A DRIVEWAY ON THE SIDE OF ANOTHER COMPANY'S BUILDING THEN RUNNING THRU THE MEDIAN AND HEADING FAST TOWARD THE BUILDING BEFORE I SLAMMED THE BRAKE IN TIME TO STOP THE CAR ~15 FEET AWAY FROM HITTING THE BUILDING. THE DRIVER'S SIDE OF THE CAR SCRAPED A TREE ON THE MEDIAN AND THE DRIVER SIDE MIRROR BROKE THE TREE SUPPORTING POLE. AFTER THE CAR WAS TOWED TO TESLA SERVICE CENTER 2 HOURS LATER, THEY REPORTED THE NEXT DAY THAT THEY FOUND NO ERROR WITH THE CAR. I WAS TOTALLY CAUGHT OFF GUARD BY THE UNINTENDED ACCELERATION OF THE CAR THAT ICOULD NOT BRAKE EARLY ENOUGH TO STOP THE CAR ON THE MEDIAN AFTER IT CLIMBED OVER THE CURB. IT WAS A CLEAR DAY, I TURNED LEFT INTO THE PARKING WITH CAUTION AND FOCUS ON SAFETY ESPECIALLY KNOWING THE WHITE TRUCK WAS NEARBY AND THE MEDIAN WITH THE TREE WAS VISIBLE IN FRONT. THIS IS WHERE I PERFORMED BACKING UP MY CAR ALMOST DAILY AT WORK SO I COULD CHARGE MY CAR IN THE COMPANY'S EV CHARGING PARKING LOT FOR THE LAST 6 MONTHS. BEFORE, DURING AND AFTER THIS LIFE THREATENING INCIDENT, MY HEALTH, MIND, EYE SIGHT AND AWARENESS WERE AND ARE VERY GOOD. I DO NOT SMOKE, DRINK OR HAVE ANY MEDICATION THAT CAN AFFECT MY DRIVING CONTROL WITH SAFETY. I REPORTED THIS UNINTENDED ACCELERATION TO MY AUTO INSURER AND ASSESSMENT FOR DAMAGE REPAIRED WITH TESLA AUTO BODY SHOP IS UNDER PROGRESS. THERE IS NO POLICE REPORT BECAUSE THE INCIDENT HAPPENED ON PRIVATE PROPERTY

FOR MANY MONTHS, MY TESLA'S COMPUTER WOULD REBOOT OR JUST SHUT DOWN WHILE I WAS DRIVING. THAT WOULD STOP THE DEFROSTER, THE ABILITY TO BACK UP, AND MULTIPLE DRIVING ISSUE. TESLA SUUGGESTEC THAT I REPLACE THE CHIP AND THE SCREEN, I PAID$2500. THEY REFUSE TO PAY FOR IT DESPITE A RECALL ON THE SPECIFIC ISSUE. IT IS WELL DOCUMENTED WITH TESLS

I experienced the "Phantom Braking" phenomenon while driving on freeways. It has happened 3 or 4 times in the last year or so. I did not see any obvious reason for the car to have slowed down dramatically because there wasn't a car in front of me at such instances. it occurred while Autopilot was engaged. It has happened on different freeways (I-680, I-880), traversing in different directions and at different times of the day.

THIS IS A COMPLAINT ABOUT THE TESLA AUTOPILOT. PLEASE NOTE THAT THE VIN OF A RANDOM TESLA MODEL S HAS BEEN USED TO ENABLE ME TO FILE THIS COMPLAINT. HERE IS A FRESHLY UPLOADED YOUTUBE VIDEO OF SOME KIDS FOOLING AROUND WITH AUTOPILOT AND PUTTING MANY LIVES AT RISK. HTTPS://WWW.YOUTUBE.COM/WATCH?V=GXGLMMMFKUA DESPITE SEVERAL FATALITIES AND THE SCATHING NTSB REPORT PEOPLE ARE STILL DOING DANGEROUS THINGS. NOTHING HAS BEEN DONE TO CORRECT THE MISCONCEPTION THAT AUTOPILOT IS SELF DRIVING AND THAT IT IS SAFE TO RELY ON IT. THIS PUBLIC MISCONCEPTION WAS DELIBERATELY ENGINEERED BY ELON MUSK. AUTOPILOT SHOULD BE GEOFENCED SO THAT IT IS IMPOSSIBLE TO USE IT ON UNDIVIDED ROADS. DRIVER MONITORING SHOULD BE IN PLACE TO PREVENT THE KIND OF STUPIDITY SHOWN IN THIS VIDEO. SINCE IT IS IMPOSSIBLE TO UNDO THE WIDELY HELD BELIEF THAT AUTOPILOT IS PERFECTLY SAFE AND INDEED SAFER THAN A HUMAN DRIVER THE ONLY SOLUTION IS TO DISABLE TESLA AUTOPILOT IMMEDIATELY VIA AN OVER THE AIR UPDATE. THE WRECKERS YARDS ARE FILLED WITH ASTONISHING NUMBERS OF CRASHED TESLAS. HTTPS://POCTRA.COM/TESLA-FOR-SALE IT IS A CERTAINTY THAT MANY OF THESE TESLA CRASHES WERE CAUSED BY DRIVER DISTRACTION I.E. TOUCHSCREEN AND/OR AUTOPILOT. I PETITION NHTSA TO DEMAND AN IMMEDIATE RECALL OR DISABLING OF THIS DANGEROUSLY MISNAMED AUTOPILOT. THANK YOU. KEEF

STOPPED AT A BUSY CITY STREET INTERSECTION FOR AROUND 2 MINUTES WAITING FOR THE GREEN LIGHT. MY CAR WAS SECOND CAR FROM THE INTERSECTION ON A SLIGHT UP SLOPE. OBVIOUSLY THE BRAKE WAS FULLY ENGAGED BUT MY CAR SUDDENLY CREEPS UP SLOPE AND GENTLY BUMPS INTO THE CAR IN THE FRONT. THIS IMPACT PUSHES THE OTHER CAR FORWARD AND MY CAR ROLLS BACK. THE FORWARD COLLISION ALARM WENT OFF BUT I COULD DO LITTLE TO STOP THE CAR OTHER THAN TRY AND PRESS ON THE BRAKE EVEN HARDER. THE CAR AGAIN ROLLS UP AGAIN AND GENTLY BUMPS THE OTHER CAR AGAIN.
