Adaptive Cruise Control problems of the 2025 Tesla Model 3

Tesla fsd out of control and run into a light pole.

While driving at highway speeds, using cruise control, the vehicle occasionally brakes for no apparent reason with no vehicles or obstacles in the way. The braking is severe and could potentially cause me to be rear ended. The dealer inspected the vehicle and could not reproduce the problem. There has been no previous warning to the braking.

Tesla full self-driving (supervised) was engaged at the time of the incident. The vehicle was traveling at low speed on a straight roadway when it unexpectedly initiated a sudden steering maneuver out of its lane toward a roadside structure (outdoor restaurant seating area), resulting in a collision. The driver did not provide steering input prior to or during the maneuver. There were no warning messages or alerts indicating a hazard or need for evasive action before the event. Vehicle telemetry data reviewed after the incident indicates that the steering system executed a rapid, large-angle deflection without corresponding driver input, consistent with a system-initiated maneuver. The system continued to apply throttle during the event. The incident created a direct safety risk to the vehicle occupants and nearby pedestrians due to unintended vehicle path deviation toward a fixed structure. Additional context: when this car was in the repair shop for repairs, we were told that during the replacement of the dashboard/computer system, the technicians observed a persistent system code that would not clear. Tesla technical support was contacted, and the system was ultimately reinstalled to resolve the issue. While the direct connection between this code and the fsd malfunction is unknown, the persistent code may indicate preexisting software system instability. The vehicle has been inspected by repair professionals, and supporting data (telemetry and video) is preserved and available for review upon request. Cause of the malfunction is currently unknown, but evidence indicates a failure in the driver assistance system’s steering control.

Inused Tesla to back up from my driveway and it hit my gate little damage but the car did it . Did not calculate and crash sensor sisnt work car crash the car on fss (automatic pilot).

I was driving on a straight interstate road between 60-70 mph using full-self driving around 4:15pm and there was no traffic in front, behind, or next to me. Suddenly, the car tried to make a sharp right turn that felt like more than an obstacle avoidant move or lane keeping move. I had to grab the wheel even harder than I was (my hands were fortunately on the wheel) and force it back into the lane. If I did not make this intervention, I would've gone off the road and crashed.

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 [xxx] at approximately [xxx], I was driving northbound on [xxx] in phoenix, arizona in my 2025 Tesla Model 3 using Tesla's full self driving (fsd) (supervised) mode, when the incident occurred. I was paying close attention while driving in the left-most, non-hov lane coming up to a bend just before the [xxx] overpass, when I noticed traffic ahead slowing down and coming to a stop. I monitored fsd as it went through the act of braking; however, it seemed to wait a little longer than I would have expected before it actually started to brake, and when it did, the fsd system had to brake more aggressively than I've previously experienced. As it neared the end of the braking event (while the car was still moving), the fsd system disengaged itself without any input from me (neither by manually applying the brake pedal, applying torque to the steering wheel, or pressing the fsd button). When the fsd system disengaged itself, my vehicle continued forward. Had I not been paying attention, my vehicle would have collided with the rear end of the vehicle in front of me. Since I was paying close attention, I immediately slammed on the brakes after noticing that fsd had disengaged itself. I have dashcam footage of this event from the Teslacam system; however, it does not include audio or telemetry data. Even without that, you can see in the video that my car noses down while fsd applies the brakes, then noses up when fsd disengages itself, and then noses down again when I apply the brakes manually. (the dashcam footage exceeds the 20mb limit; however, I can provide it via other means upon request. ) it should be noted that I am an experienced Tesla fsd user, as I used it for over a year in my prior vehicle (2018 Tesla Model 3, which had been upgraded with the hw3 fsd computer), and this is the first time I have ever experienced a near collision event while using fsd or an event in which fsd disengaged on its own.

Tesla Model 3 2025, fsd v13. 2. 9, red light violation: video enclosed: [xxx] it just happened and I have no more information can provide. Apparently fsd didn't warn me that it will run a red light. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

I love my vehicle and its technology. However after installation of the latest (fsd v14) update, I observed issues I believe pose a risk to the safe operation of the vehicle. I have made dozens of reports for 30+ days to Tesla for these issues. 1. Driving profiles and speed the update features multiple driving profiles (e. G. , "sloth", "chill", "standard", and mad max). Only the "sloth" profile drives at the “speed limit” (what their outdated map thinks speed limit is). All other profiles drive over the posted speed limit (sometimes significantly). The ability to manually adjust the speed limit setting has been removed or disabled in these profiles. Once the vehicle is in a profile, the system stays in its own selected speed. This behavior prevents the driver from easily controlling the maximum speed when using the system, undermining driver-intent. 2. Incorrect or outdated speed limit data the vehicle frequently displays incorrect speed limits: for example, school zones, reduced speed zones, temporary speed changes, work zones, and even a busy high way I drive everyday that’s been changed for 3 months now, are often not recognized or updated in the system. On several occasions over the past months, the system continued to use an outdated or incorrect posted speed, despite the road clearly being a lower limit. Because the system uses the erroneous speed data as the basis for its automated driving decision (and without manual override of speed in fsd), this situation increases risk-especially in areas where lower speed limits are enforced for safety (pedestrian zones, near schools). 3. Safety risk description the lack of manual speed adjustment under autonomous mode means the driver has less control over vehicle speed when using fsd, reducing the driver's ability to mitigate risk in a dynamic environment. I’m asking for Tesla to either make sure they have constant real time speed limit data, or allow again for manual speed adjusts when in fsd.

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 shows the actual 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. 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. Tesla has made 5 attempts to fix this without success. On the last attempt (September 24, 2025), they refused to answer my questions such 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.

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.

My vehicle is equipped with supervised fsd and has had couple of issued on the intersection of [xxx] and [xxx] in portsmouth, virginia. It seems every time I stop at the light, the system recognizes the red light and stops, but shortly after it wants to keep advancing forward although the light is still red and has not changed. The vehicle has also had a problem staying on lane at light on the intersection of [xxx] and [xxx] in suffolk as it is getting ready to turn left prior to entering the entrance road to [xxx] . The image in the screen is correct and the lines are in place, but the vehicle has trouble staying with in the line and needed to be corrected.

I have a safety concern regarding Tesla's full self driving (fsd) supervised system. V13. 2. 8 being the latest customer version. Since the update to fsd v13 in December, I have consistently used it on a daily basis. While it performs great on city streets, it consistently caused a serious safety risk on the freeway: it habitually tailgates cars at high speeds of 70-80 mph on the freeway. It does this even when there is no traffic and the other lanes are wide open. I have experienced this on both a Model 3 (2025) and a model y (2024). I am writing this complaint here hoping you will pay attention to it, as despite my best efforts, Tesla has ignored my feedback. I even opened a service ticket about it at one point, and the service tech couldn't care less. Not maintaining proper distance to the cars in front on the freeway puts the passengers at high risk for a rear end collision. If Tesla is to launch an unsupervised version of their fsd system, this problem must be addressed first!.

After installing Tesla ota software update 2024. 45. 32. 15, my vehicle experienced critical system failures. Upon entering the car the next morning, I noticed that all cameras were non-functional, and navigation had completely stopped working. This posed a serious safety concern, as features like autopilot, parking assistance, and basic visibility enhancements (such as rearview camera functionality) were unavailable.
