2017 Tesla Model S vehicle speed control 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.”

“Stoped at intersection. While trying to engage signal lights, hit the stalk below that engages full self driving. Car immediately jumped into intersection .in front of another car and almost collided. Since the last update, Cars with my configuration wave been acting irradely and it is not safe to use FSD.”

“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.”

“-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…”

“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”

“This is aTesla Model S electric car. The battery was 80% charged at the time of the incident. Under normal driving at a speed of around 40 MPH in a city road road, suddenly the car lost power. The steering wheel locked and I had no control over the car. Display screen in the instrument panel and the large central tocuh screen display blacked out. A few seconds later, the car control returned and I was able to safely drive the car. But, the momentary loss of control is dangerous and scary.”
