2020 Tesla Model 3 vehicle speed control problems

“I own a 2020 Tesla Model 3 purchased in 2023 with Full Self-Driving (FSD) included for the lifetime of the car. I used FSD satisfactorily for years, but Tesla recently removed the maximum-speed control I previously used while FSD was engaged. I have personally experienced this change. FSD selects speed, but I can no longer impose the maximum I previously could set. I consider this a safety issue: unwanted speed requires the driver to detect it and intervene, potentially exposing occupants and other road users to excessive speed. The human driver remains responsible for safe, lawful operation and faces possible speeding tickets. I have read reports describing maximum-speed control as an "anti-pattern." I do not consider that an adequate safety justification for removing a preventive control. Learning a driver's preferences should operate within an explicit speed ceiling. I believe Tesla has the engineering capability to develop and validate a solution that preserves both FSD functionality and effective driver control. I request NHTSA investigate and require a remedy if a safety defect is established. My position is that affected FSD systems should not operate on…”

“I was making a right turn from the parking lot onto the street, a maneuver I have made hundreds of times previously without any issue. My foot was on the accelerator pedal as normal for this turn. The vehicle accelerated far faster than intended for this maneuver, with tires screeching, and continued across the width of the street. The vehicle's front left wheel struck the curb on the opposite side of the street from the parking lot exit. The wheel sustained significant damage, and the wheel rim was torn. When I regained my bearings, I lifted my foot off the accelerator and the vehicle slowed down. At the time, I believed a serious crash was imminent. I was able to drive the vehicle home, which was about 1 1/2 miles away, but it is not safe to drive so I won't drive it until it is repaired. I am aware that Tesla and NHTSA have attributed many prior sudden acceleration incidents to drivers unintentionally pressing the accelerator when intending to press the brake. Due to the vehicle's regenerative braking, I rarely use the brake pedal during normal driving, which makes this explanation virtually impossible in my case. I am also aware that NHTSA reopened an…”

“On July 11 at approximately 6:47 a.m., I was operating my Tesla Model 3 on Interstate 65 in Hart County, Kentucky, with Full Self-Driving (FSD) engaged during normal highway travel. Approximately one hour earlier, I had departed a highway rest area after sleeping from the previous day’s travel. Rain developed during the trip, but I observed adequate visibility, apparent roadway traction, and I was not impaired. I was traveling in the far-right lane of a three-lane interstate. The posted speed limit was approximately 70 mph; however, FSD limited the vehicle to approximately 65 mph and displayed warnings indicating that the higher speed was unavailable. While FSD remained engaged, the system initiated a lane change from the far-right lane into the center lane. After entering the center lane, the vehicle began displaying repeated warning messages and FSD disengaged multiple times. I attempted to locate settings related to the warnings on the touchscreen but could not identify an available adjustment. During the third disengagement, I perceived that the vehicle continued braking without releasing while steering resistance increased significantly. The steering wheel…”

“The newer versions of FSD do not allow driver control of the max speed. The current versions allow you to set a maximum speed with a scroll wheel on the steering wheel.”

“Incident #1 Vehicle sitting at a red light. After several seconds the vehicle operating under Tesla FSD suddenly started to drive as if the light had turned green, which it had not. I stopped it immediately. Incident #2 Vehicle was stopped a t a red light and started forward again as it the light had changed but had not. I noticed a flashing red light at the next intersection a few hundred feet away. So, I went around the block and tried again and it behaved the same. After a few seconds it started to go again. There was not another light near where the first incident occurred.”

“Vehicle must have thought a shadow line in the road from a bridge indicated a wall I was about to hit, as it slammed on the breaks in the middle of the freeway. Car behind had to swerve to avoid. On the same trip, several nags of 'keep eyes on the road' were incorrect, as my eyes were directly on the road, but phone was in hand functioning as a microphone taking voice memos. Car proceeded to shut itself down while in the middle of the freeway, causing me to go slower than traffic and put me in danger as cars behind me had to swerve or lane change to avoid me as I tried to pull off to the shoulder. These forced shutdowns from incorrect 'nag fails' are causing safety issues. Nag failures should not forcibly shut the car down. Not sure if this is being enforced by NHTSA, or why Tesla is choosing to disable their auto steer or FSD when drivers are detected to be failing nags - nags should be there to help drivers, and potentially the nag data/cab video can be used after the fact should a user failing nags be involved in an accident for insurance dispute resolution, but shutting the cars down themselves is causing issues.”
