2025 Tesla Model 3 Speed Control & Cruise Problems

After upgrading to FSD (sull self driving supervised) v14, The speed limit function HAS BEEN REMOVED. THERE IS NO WAY TO SET A MAX SPEED FOR CRUISE CONTROL. THE CAR SPEEDS UNSAFELY AT ALL TIMES WHILE IN FSD. THERE IS NO WAY TO CONTROL HOW FAST THE CAR CAN GO. It just "thinks" what speed is best. It constantly speeds 7-10 over in every setting above "SLOTH". SLOTH setting still DOES NOT have a speed limit setting. THIS IS VERY DANGEROUS. THERE IS NO EXCUSE FOR NOT HAVING A MAX SPEED SETTING.

In the New Tesla update to Full Self Drive they removed the ability to adjust the speed control while using FSD yet state "Note: You are responsible for the speed and control of your vehicle at all times, whether FSD (Supervised) is enabled or not."

On December 31, 2024, I purchased a new Tesla Model 3 Long Range with Full Self-Driving (FSD). The problem is the car goes faster than it should when Full Self-Driving is activated. I have attached an example photo of the Tesla screen taken while the car is being controlled by FSD. It shows that the speed limit of the road is 35 MPH, and the car is traveling at a steady speed of 51 MPH. It also shows a “Max Speed” of 64 MPH which means the car may travel that fast on this road if it chooses to. This is clearly a safety issue which can lead to accidents. Tesla has made 5 attempts to fix this without success. On the last attempt (September 24, 2025), they refused to answer my questions such as: Why does the Max Speed suddenly change to a value much higher than my specification? They simply stated that the system was operating as designed. Really? It’s design to drive 51 MPH in a 35 MPH zone? Furthermore, they went on to say I should disengage the FSD system or intervene manually if I believe the car is operating in an unsafe manner. One reason I purchased this car was for FSD. I would expect them to fix it rather than my having to abandon this feature that I pay for. I hope you will encourage Tesla to fix this issue before there are any more FSD-related accidents.

I want to add an update to my previous report # 11690629. I think it would be helpful to provide what the Max Speed should be based on my input. So, I will just resubmit the previous report with some additional information. On December 31, 2024, I purchased a new Tesla Model 3 Long Range with Full Self-Driving (FSD). The problem is the car goes faster than it should when Full Self-Driving is activated. I have attached an example photo of the Tesla screen taken while the car is being controlled by FSD.

It also shows a “Max Speed” of 64 MPH which means the car may travel that fast on this road if it chooses to. Since I use an Offset of 10%, the Max Speed in this 35 zone should be 39 MPH. However, the car increased it to 64 MPH, and I certainly did not use the right scroll wheel to increase it. This is clearly a safety issue which can lead to accidents.

The contact owns a 2023 Tesla Model 3. The contact stated that while in reverse (R) and backing up at approximately 5 MPH down a slight incline, the vehicle accelerated inadvertently. The contact stated that she turned the steering wheel to the right to get on the road. The contact had taken her foot off the accelerator pedal when the vehicle gained momentum and drove backwards about 50 feet and crashed into a tree with the rear end. The contact stated that the passenger side rear bumper and an aftermarket trailer hitch were dented, crumpled, and bent. The contact stated that the rear windshield was cracked on the driver's side. The contact stated that the regenerative braking feature never engaged. The contact also stated the steering had locked, and she was unable to turn the steering wheel. The contact stated that there were no warning lights. The tree had stopped the vehicle, and the contact stated that she was unable to restart the vehicle. The contact stated her left eye had a bruise, and there were no other injuries. The police were called, but advised that since there were no serious injuries or other vehicles involved, there was no need to send an officer to the scene. The manufacturer was notified of the failure. The contact had the vehicle towed to a dealer. The vehicle was not diagnosed and was not repaired. The failure mileage was 9,840.

Had ACC set on 80 MPH on the hiway yesterday. A vehicle was passing me and the Tesla suddenly applied heavy brake pressure to the point of tires screeching. Speed dropped very quickly to about 50 MPH. I had not touched the brake pedal. Brakes released and speed resumed to 80 MPH. VERY SCARY and high risk of rear end collision. Lucky nobody was behind me. Don’t want to experience that again.

Automatic Emergency Braking, for no reason, occurred twice while on autopilot. Driving on a remote interstate, during the day, no one and nothing in front of me (and I had a passenger that can confirm), and suddenly the car rapidly braked extremely hard. If I hadn't slammed the accelerator immediately I would have been rear ended the first time. The second time, no one was near me. I am attempting to report this to Tesla, although that is somewhat difficult as I am just getting bounced around their automated systems. My passenger and I, and the car behind us were put at serious risk of collision at ~ 85 mph, due to the completely unexpected and extremely rapid braking. This was under simple autopilot, no FSD or other driving assist. Nothing has been inspected yet, or reproduced past these 2 incidents. No warnings or symptoms occurred before or after this issue. Slightly terrified to use autopilot now, as if a semi-truck had been behind me, we would have been flattened. It is also difficult to turn off this so-called "assist" with emergency braking, it auto-reverts to on every start up, which is also dangerous.

I went to drop my son to a summer program to a park. After dropping him, as soon as I started, car just accelerated very fast and went on the sides. I was able to turn the steering back into road but it kept speeding and went on the other sides. In the process, cars tires got impacted. Within 5-10 secs, car got from one side walks to the other side walk and then car stopped somehow. Fortunately, it did not impact any other cars parked or other cars on the road. But the whole thing was very scary.

As I was pulling into a parking spot with my new 2025 Model 3 Tesla, I removed my foot from the gas to slow the car - the appropriate way to do so which is called Tesla's One Pedal Driving. The car did slow but then suddenly surged forward at an alarming rate. I have 100% certainty that my foot was not on the gas at this moment. The car was stopped by a large concrete planter just in front of me, however, if that planter was not there, my car would have been through the glass of an office building or in a head on collision with another car in the lot. If there was a person walking into the building, they would have been dead. A witness approached me and mentioned that the car seemed to act erratically. I have been in touch with Tesla about the issue and am awaiting response.
