“The latest version of Tesla FSD software does not let me fully control my speed. You can switch profiles or stop using Full Self-Driving, but you cannot set the speed to what you want. In the last version, you could use the right scroll wheel to increase or decrease the speed. Now that shifts profiles but even that does not give you control over what exact speed you are driving”
NHTSA complaint #11700335, filed 2025-11“June 30, I was driving an highway, PA 376 during a rain storm, FSD 60 MPH 4-5 PM. The rain was heavy, vehicles in front of me flashing their emergency lights, I attempted several times to slow down, Acceleration Modes, towards me. Vehicle would not slow down, heavy rain and puddles blurred my vision, thinking I would rear end the vehicle in front of me. Traffic was light due to the rain, FSD needs better software to slow down during weather conditions.”
NHTSA complaint #11749426, filed 2026-07“While driving along a few roads using Traffic Aware Cruise Control (TACC) or AutoPilot (AP), the car will suddenly brake for no reason at all. Speeds reduced from 75 to 50 in 2 seconds. Had there been a car close behind me, we may have collided. I am able to reproduce this on several other roads as well. I have not yet reported this to the manufacturer, but a review of internet forums shows this to be a relatively common occurrence among owners. They refer to this as Phantom Braking.”
NHTSA complaint #11673710, filed 2025-07“When using cruise control (traffic aware cruise control and autosteer) the car acts dangerously and stops for no reason. I've been driving on open roads with no traffic in front of me on regular roads, the car will slam on the brakes and it causes the people behind me to need to slam on their brakes as well. I feel like I'm going to get into an accident constantly... I was on the freeway and no one around in front of me and the car slammed on the brakes to almost a stop on a 70 mph speed limit road. …”
NHTSA complaint #11700663, filed 2025-11“It was snowing and I was driving slow. About 8:40am, Feb 6th, 2026, I got a One pedal driving disabled alert just for a moment, then tried to stop before an intersection because a signal was turning to red. However, break didn't work and I had to enter the intersection under a red signal. Fortunately, there was no car in front of me, also a car coming from the side didn't notice signal changed. No accident, but very very scary. On Dec 6th, I also got an alert One pedal driving disabled and even after I released an accelerator pedal, speed didn't slow down. …”
