2025 Tesla Model 3 Driver Assist & ADAS Problems

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.

The Tesla FSD performed in a dangerous way. It came into a left lane when a speeding truck was in the lane and nearly hit my car. This occurred on Nov 12 around 5:30 pm near floor and decor at Kolb and Broadway Intersection in Tucson AZ. I engaged FSD to return home in Oro Valley. First the car did not follow straight path going from the parking store lot to make a right trun and enter Kolb road. It made right turn and left turn and then right to Kolb road to turn right. It was a busy time in the evening. When an opening was found it entered Kolb road and then rapidly zig zagged to change lanes to try to enter left turn lane only on Kolb to turn on Broadway. In the left most lane, it did not detect a fast approaching truck. The truck honked, and I took control of the car and sped through the intersection to avoid collision.

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.

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.

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.

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.

Phantom braking from freeway speed to almost a stop, with no other vehicles presenting issues nearby. Three occurrences so far.

FSD Malfunction, inspection available. Yellow double lines were not recognized around a turn, causing the car to steer towards oncoming traffic. UNKNOWN. Vehicle was declared fully functional by Tesla Dealership. No warnings, vehicle had many symptoms prior to the last event in which I decided to service the vehicle. First critical malfunction May 21, 2025.

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.
