general problems of the 2025 Tesla Model 3

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. ".

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 Only the "sloth" profile drives at the “speed limit” (what their outdated map thinks speed limit is).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 Incorrect or outdated speed limit data the vehicle frequently displays incorrect speed limits: for example, school zones, reduced speed zones, temporary speed changes, work zones,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 On several occasions over the past months, the system continued to use an outdated or incorrect posted speed, despite the road clearly being a lower limit.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.

On September 7, 2025 at ~7:53 pm, my 2025 Tesla Model 3 operating with full self-driving (fsd) engaged performed an aggressive, uncommanded turn while under computer control. The maneuver occurred so abruptly that I could not safely override steering before impact, and a crash resulted. The Tesla app trip view for trip 3 (7:34–7:53 pm) shows “vehicle on fsd” for 18 min 54 sec and records an “aggressive turning” event at 7:53 pm (2. 0 sec) immediately before the trip ended (screenshot attached). This reflects a steering/driver-assist control defect in fsd’s turning behavior and a failure of collision-mitigation to prevent the crash. I sustained bodily injuries and the vehicle incurred significant damage. I request that this incident be treated as a safety-critical malfunction warranting investigation and corrective action.

On [xxx], at just 9,526 miles, my brand-new 2025 Tesla Model 3 (VIN: [xxx] ) suffered a front motor/inverter failure. The vehicle displayed the warning “front motor disabled. ” Tesla vallejo service confirmed this and replaced the front drive inverter (3du). A catastrophic drivetrain failure at under 10,000 miles is unacceptable and raises serious concerns about reliability and safety. It still doesn't not accelerate as before. In addition, since delivery on [xxx], this vehicle has had persistent rattling and vibration issues in the cabin. I have returned to Tesla vallejo multiple times (April, June, July, and August 2025). Each time, the service manager, steve mcnerney, dismissed or minimized my concerns, blaming “seatbelt rattling” or claiming the issue could not be replicated. After July, I even sent three separate videos clearly documenting the noise, yet the most recent service invoice still instructed me to “provide a video,” showing Tesla ignored or failed to record my evidence. This ongoing defect has been reproduced and confirmed at Tesla service but remains unresolved. Tesla’s dismissive handling and failure to fix the defects create both safety risks and loss of confidence in the vehicle. A front motor failure while driving could result in loss of power, reduced acceleration, or unsafe driving conditions. Tesla has failed to provide a reliable or safe resolution despite repeated repair attempts and clear evidence. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

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.

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.

I have had this happen twice, once on city streets going to work the car was not in auto pilot and it went from 40mph to 0mph instantly. If there was a car behind me I would have gotten slammed into. The second time, my mother was in the passenger seat and I was on the freeway going about 75 to 80mph and it was on auto steer and the car went from the speed I was going to almost 0 and I instantly took control of the vehicle. We both could have been killed because of the last incident and I thought the cameras saw something on the road but there was nothing there. No cars were near me when both events occurred.

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.
