36 Adaptive Cruise Control problem of the 2025 Tesla Model Y

Failure Date: 01/14/2026

Tesla supervised self driving (fssd) update 14 removed the ability for the vehicle operator to set speed targets. Additionally, their system is unable to accurately determine speed limits for many roadways. The discrepancy between fssds perceived speed limit and actual speed limit can be as much at +/- 25mph. The discrepancy can occur suddenly and at any time during a drive, even on stretches of road with a consistent speed limit. This results in moments of dangerous acceleration and/or deceleration that is not requested by the vehicle operator or can be reasonably anticipated. This causes erratic driving behavior to both the Tesla and to other motorist in the vicinity. Erratic, unpredictable driving is a major cause of traffic accidents that can lead to serious damage, injury, or death. Prior versions allowed the operator to set a speed target, similar to standard cruise control, that the vehicle attempted to maintain and would not exceed. Fssd v14 does not allow the vehicle operator to have any control over the speed of the vehicle to any degree that meaningfully contributes towards safe, legal driving.

37 Adaptive Cruise Control problem of the 2026 Tesla Model Y

Failure Date: 01/07/2026

I was driving in full self driving mode on my Tesla Model Y. The car stopped at the left turn stoplight as it does normally. And then while the light was still red and the cross traffic was green (traffic flowing), the Tesla released the brake, accelerating into the intersection. I stomped on the brake and kept the car from fully entering the intersection, then continue home without using full self driving mode any further. If I hadn’t intervened, the Tesla would have caused an accident, injury, or even death.

38 Adaptive Cruise Control problem of the 2024 Tesla Model Y

Failure Date: 01/03/2026

On Saturday morning January 3, 2026 I was driving with my wife, daughter and dog. There was light rain at the time and I had my adaptive cruise set at approximately 72 mph. I was driving our 2024 Tesla y. At approximately 10:21am the rear of car began to slide right as we entered gradual left curve, possibly because we hit water on road. I tried to slightly correct right and when I did that the steering wheel aggressively corrected back left which put us into a slide. Within a second we hit a tree on the passenger side. The impact was severe and on the passenger side door where my wife was sitting. At that time I theorize that my dog was ejected out of the back window and thrown across the freeway. We then rolled in the other direction (I dont know how many times) down a hill and settled upside down. I immediately smelled smoke and began to try get out of my seatbelt but I couldn’t. I carry a knife and I was able to cut myself out. I then tried to open door and could not so I began punching the glass and eventually got it moving and pushed on it and got it open. I slid myself out, turned around and saw car was on fire. I pulled my daughter out and then began extracting my wife. She was unconscious and had obvious orthopedic injuries. I am 100% confident that had I been driving my other vehicle (non Tesla) that this accident would have not occurred. The Tesla and its steering system caused this accident. On top of that, the batteries immediately caught fire, my seatbelt release button did not work, and the electric door button did not work. Had I not been carrying a knife and strong enough to punch door open this story would have ended up differently. The car completely burned. As far as I know, this was the first time this exact issue presented itself. However, when looking online its seems this issue is fairly common with Teslas in wet weather.

39 Adaptive Cruise Control problem of the 2026 Tesla Model Y

Failure Date: 01/01/2026

Vehicle equipped with Tesla full self-driving (supervised v 14. 2) software exhibits unsafe automated following behavior. The system maintains following distances that are too short at steady speeds, including behind stable lead vehicles with no braking or traffic disturbances. Tesla’s own safety score system flags this behavior as “following too closely,” indicating elevated collision risk. However, the driver has no available control to adjust minimum following distance or impose safer headway while using fsd this represents unsafe autonomous tailgating behavior with loss of driver control authority over safe following distance, creating increased risk of rear-end collision and hazardous automated driving conditions. Tesla offers several controls (sloth, chill, standard, hurry, and madmax) modes, none of which solve the issue if the driver in front is driving the speed limit. My car under fsd will crowd (or tailgate) the front car regardless of the mode. In one instance, I was following a car under fsd in sloth mode and it made the car in front of me pull over just to get me off their tail. . . . This is certainly now how I wish to drive, and don't want my car driving this way. Failure mode: automated headway policy dominance, lack of driver override, unsafe autonomous following distance.

40 Adaptive Cruise Control problem of the 2022 Tesla Model Y

Failure Date: 12/30/2025

On December 30th, 2025, my wife experienced a serious and unexpected safety event while using autosteer in one of our Tesla Model Y cars (we own two of them). The version of the vehicle software in use was v12 (2025. 26. 8) and the full self driving (supervised) software was v12. 6. 4. The vehicle came to a complete stop at a red traffic light on northbound san gabriel blvd in pasadena at the intersection that controls entry to the I-210 west. After waiting for approximately 55 seconds, autosteer initiated forward movement into the intersection while the traffic light was still red. The vehicle’s movement was not caused by driver input. My wife’s feet were away from the pedals at the time. There was no visible lead vehicle movement or other obvious external trigger. Fortunately, my wife was attentive and immediately disengaged autosteer, brought the vehicle to a stop, and carefully reversed back into a safe position. Moments later, multiple fast-moving vehicles crossed the intersection in front of her path. Had she not intervened promptly, there was a realistic risk of a serious side-impact collision. This serious incident was reported to Tesla on 12/30/2025 including a video of the incident. In my correspondence, I requested that all relevant vehicle telemetry, autosteer/fsd logs, and any uploaded video associated with this time and location be preserved and reviewed. As of today (7 weeks later) they have not followed up with me. The 18-second video was recorded by an independently installed viofo dashcam, which clearly shows: . The vehicle stopped at a red light, . The light remaining red, . And the vehicle beginning to move forward unexpectedly.

41 Adaptive Cruise Control problem of the 2024 Tesla Model Y

Failure Date: 12/30/2025

Autopilot was engaged and active at the time of the incident. The vehicle failed to detect a stationary piece of road debris (appearing to be a dropped vehicle part) located in the driving lane. The system did not provide any warning, slow the vehicle, or attempt an avoidance maneuver. The vehicle drove directly over the debris, resulting in damage to the lower exterior/body panel. Road and traffic conditions were normal. This raises concerns about autopilot’s object detection and hazard response capabilities.

42 Adaptive Cruise Control problem of the 2026 Tesla Model Y

Failure Date: 12/16/2025

Vehicle equipped with Tesla full self-driving (supervised v 14. 2) software exhibits unsafe automated behavior due to removal of driver speed control. The system infers speed limits and driving speed without allowing the driver to set a safe maximum speed. In residential neighborhoods with children, pedestrians, and shared social spaces, the vehicle drives at model-inferred speeds that are socially and physically unsafe. Driver is unable to impose a lower safe speed limit without disengaging. Tesla removed previous option for driver to adjust speed. In a state park campground, the system failed to detect a posted 15 mph speed limit and inferred a 55 mph limit. The vehicle accelerated to unsafe speeds on narrow, pedestrian-heavy roads, with no driver ability to cap speed while under fsd. This represents a loss of human override authority and unsafe autonomous system behavior, creating pedestrian hazard and safety risk. Failure mode: automated speed inference dominance, map prior misclassification, lack of driver override, unsafe autonomous acceleration in pedestrian environments.

43 Adaptive Cruise Control problem of the 2026 Tesla Model Y

Failure Date: 12/16/2025

There is a serious safety-related fsd (full self driving) fundamental design flaw with stop sign behavior. On previous versions and on the latest and best version of fsd (currently that is v14. 2. 1. 25) when fsd approaches a stop sign and there is no white painted stopping line, fsd will make its full initial stop (also called the zero-speed stop) directly at or behind the stop sign instead of making the initial full stop beyond the stop sign at a location where the driver can see cross traffic. Sometimes the fsd initial full stop is 20, 30, 40, even 50+ feet back away from the edge of the road. At these distances from the edge of the road, most of the time, there is no visual of cross traffic left and right. The fsd stop then turns into the fsd "creep" where fsd, after stopping 30 feet back will then commit to the turn from 30 feet back giving drivers little to no time to see cross traffic. If I am the supervisor of fsd who is liable for my safety and my vehicle's safety, I need to be able to see cross traffic before my car (with fsd engaged) decides to commit to the turn, but fsd does not care if the driver can see. The "creep" is perhaps the least human-like manuever that fsd performs. From the stopped location directly at the stop sign, they creep may inch up and stop again, it may inch up a couple times and stop again, it may pull up to the edge of the road and stop again, or it may just pull out into oncoming traffic in one swift motion. Bc of this behavior, fsd has almost got rear ended countless times at stop signs. Also, cross traffic see's the creep and thinks I'm about to pull out in front of them drivers go beyond the stop sign to a location where they can see to make their one and only full stop. To avoid this issue, fsd needs to do this too (I. E. Make initial full stop at the edge of the road) this is legal in mostly every state (I live in PA) Tesla has not provided a single response to these reports and nothing seems to be getting done about it.

44 Adaptive Cruise Control problem of the 2025 Tesla Model Y

Failure Date: 12/12/2025

The vehicle was in supervised full self driving on the turnpike, when all of a sudden it darted out of the lane into th grass hitting a guard rail.

45 Adaptive Cruise Control problem of the 2026 Tesla Model Y

Failure Date: 12/11/2025

When in self driving mode, which activates the adaptive cruise control, it is not possible to set the following distance. The following distance automatically selected by Tesla self driving is much too close to the vehicle in front of me. Tesla has removed the ability to set the following distance. It follows at approximately 2 seconds behind the car in front of me, regardless of my vehicle speed . . . . At 80 mph 2 seconds is not enough time for a driver to react. Following distance should be controllable by the driver. Taking away this ability deprives a driver of driving within their own limitations.

46 Adaptive Cruise Control problem of the 2026 Tesla Model Y

Failure Date: 12/08/2025

On several occasions, my Tesla Model Y has braked for no reason while using traffic aware cruise control as well as when using autopilot. I can re-create this situation on the same parts of the highway. The sudden, uncommanded stopping creates a hazardous situation with the cars being me as I may get rear ended. At this point, I do not feel safe using autopilot or tacc. I submitted a ticket to Tesla but they declined to work on it.

47 Adaptive Cruise Control problem of the 2020 Tesla Model Y

Failure Date: 12/01/2025

The full self-driving (fsd) stopped working although it was fully paid for at the time of vehicle purchase. Along with that, the car stopped receiving/installing over the air software updates, the lane markings in the display disappeared, and the automatic cancelling turn signals stopped working (requiring me to manually cancel them). I took it to Tesla service and was told that the car needs a new computer at a cost of approximately $2,300. To answer the bullet points above: 1. The main vehicle computer malfunctioned. 2. I paid for fsd for the safety it provides - without fsd, the car is simply less safe in traffic. 3. The Tesla service center confirmed that the vehicle computer has malfunctioned. 4. There was no indication of any kind, until suddenly the fsd stopped working and I noticed subsequently that downloading/installing software updates failed, lane markings disappeared, and automatic cancelling turn signals stopped working requiring manual operation.

48 Adaptive Cruise Control problem of the 2025 Tesla Model Y

Failure Date: 11/29/2025

Incident report – Tesla y – unintentional acceleration Saturday November 29, 2025, approximately 2:40 pm on the above-referenced date and time, we were returning home with the intention of pulling the car into our garage, an activity performed over a hundred times in the one year we have owned the car. Because of the need to back in to allow the car to be charged, the following procedure is adhered 1. Disengage self-driving (if it was being used) in the street prior to entering the courtyard for residence. 2. Pull forward three-quarters of the way into garage (since the residence is the last on the courtyard and the car cannot be pulled beyond the garage opening to directly back in). 3. Place car in reverse and slowly perform k-turn to back into garage. On the date in question. The following anomalies occurred: 1. After placing the car in reverse (action 2), instead of starting to back out, the car lurched forward. The brake was immediately applied and the car stopped about a foot before hitting the garage wall. 2. The brake was applied again to assure self-driving was disengaged and proceed with action 3. 3. Car was placed in reverse and accelerator was lightly pressed to slowly back out of garage. Rather than slowly back out (as was done hundreds of times) the car immediately accelerated and rapidly gained speed. 4. The brake was applied to stop the car but could not overcome the acceleration (pictures of skid marks were taken). 5. In order not to directly hit the wall located across from garage, car steering wheel was turned to minimize any direct contact ( skid marks will show turn). 6. Car came to a stop when it hit the wall causing significant damage to the car and causing damage to the wall (pictures can be forwarded).

49 Adaptive Cruise Control problem of the 2026 Tesla Model Y

Failure Date: 11/27/2025

Incident date 11/27/25 incident location: CA state highway 101between san luis obispo and los angeles. Driving conditions: daylight/dry roadway. Description of safety defect / complaint: during a single approximately 400-mile highway road trip, while using Tesla’s traffic-aware cruise control (tacc) feature enabled, the vehicle abruptly and forcefully applied the brakes on at least six (6) separate occasions without any apparent cause. On each occurrence: • no vehicle ahead was braking or decelerating, • no vehicle was merging or cutting in front of my vehicle, • no stationary or moving obstacles (including overpasses, road signs, or debris) were present in or near the travel lane, • the forward roadway was clear and unobstructed for a considerable distance. These sudden, un-commanded braking events were severe enough to cause significant deceleration, requiring me to immediately intervene by pressing the accelerator pedal to override the system. Due to the frequency and unpredictability of these phantom braking events, I no longer feel safe using traffic-aware cruise control or any Tesla advanced driver-assistance features that rely on the same sensor suite and software. I am filing this report because repeated uncommanded braking in highway traffic constitutes a serious safety hazard that could lead to rear-end collisions, particularly when closely followed by other vehicles or commercial trucks. Additional information (if applicable): • software version at time of incident: v12 (2025. 38. 9 fe 714a33a545) • full self-driving capability package: no. Enhanced autopilot: no. • any dashcam or sentry mode footage available: no I request that NHTSA investigate this recurring phantom braking issue in Tesla vehicles equipped with traffic-aware cruise control and autopilot systems.

50 Adaptive Cruise Control problem of the 2021 Tesla Model Y

Failure Date: 11/21/2025

The car has a feature called "curvature assist" that takes control of braking and steering at times when using cruise control. The incidents are at times surprising as there is no curvature present but the braking is suddenly applied. This is a surprise for both the driver and any following traffic. The car would be safer if this feature could be disabled but that is not possible.

51 Adaptive Cruise Control problem of the 2026 Tesla Model Y

Failure Date: 11/21/2025

My car installed update v12 (2025. 38. 8. 7) last night. This morning I was driving to work using autopilot when alarms sounded, the hazard lights turned on, and the screen flashed a warning that I had to take over immediately. The message included a note that autopilot had failed due to a "systems error. " the navigation and visualization screen froze, went blank, and took 10 minutes to come back on. I asked Tesla to roll back the update and they have told me that they cannot do that. I came very close to crashing into a concrete guard rail as the car was going around a turn when the system failed.

52 Adaptive Cruise Control problem of the 2026 Tesla Model Y

Failure Date: 11/19/2025

Very scary! heading west on [xxx] , my 2026 Tesla Model Y ran 2 red lights! it stopped at the first red light that sits back about 100 feet from [xxx] , and then just sped ahead, went through that light and the one directly on [xxx] and made a right turn. Crazy! information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

53 Adaptive Cruise Control problem of the 2026 Tesla Model Y

Failure Date: 11/19/2025

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.

54 Adaptive Cruise Control problem of the 2023 Tesla Model Y

Failure Date: 11/18/2025

Currently on the newest Tesla full self driving software v14. 1. 4, it is phantom breaking as well as phantom swearing out of nowhere. It is swerving and using the breaks so hard it actually affects the steering wheel and self disengages it's self (without the big-loud safety alert to immediately take over control), it just does the soft disengage audio notification, like if you wanted to cancel fsd yourself. The serious problem is that the car does not stop like it should, instead it just continues it seems like it just neutrally rolls on its own drive and twice in the last week it would swerve directly into oncoming traffic. It is not supposed to be doing this at all, especially now that the "hands off" approval is enacted. I drive about 450 miles a week and this has happened about twice a week for the last two weeks. Thank god I was paying attention all four times, but I am so worried this is going to kill someone. I have tried to call Tesla but they purposely don't staff their phones and no one answers.

55 Adaptive Cruise Control problem of the 2021 Tesla Model Y

Failure Date: 11/15/2025

In early Nov 2025 my Tesla Model Y began intermittently showing warnings about the forward collision warning system and multiple sensors being offline. Tesla service replaced a faulty connector on Nov 3. On Nov 15, 2025, about two weeks later, the car had a sudden drivetrain failure while I was parking on a steep hill. I heard a loud bang from the front of the car and the vehicle immediately lost drive power and had to be towed. Tesla diagnosed a failed front motor inverter that blew the high-voltage pyrofuse and damaged the 12v battery; they replaced those parts. The vehicle is available for inspection and the repaired components and records are with Tesla. After that repair the car needed another visit for alignment and has continued to show worrying behavior: “vcfront offline/unable to contact vcfront” in the service menu, repeated “autopilot computer overheating” messages, intermittent loss or reduction of regenerative braking (braking feel changes unpredictably), a rear right seatbelt malfunction warning (later inspected and cleared by Tesla), and what appears to be significantly increased battery drain compared to before the inverter failure. This has now resulted in four service visits within about a month, all at Tesla service centers (no police, insurance, or independent shops involved). Tesla has confirmed the inverter/pyrofuse/12v failure and says the overheating was due to an air pocket in the cooling system, but the vcfront messages, inconsistent regen braking, and increased drain have not been fully resolved or clearly explained. I am concerned that a sudden loss of power, loss of regen, or failure of vcfront/autopilot systems could recur at speed or in traffic, creating a serious safety risk. Please note that I'm only able to view partially-complete paperwork from the latest service appointment in the Tesla app. I have requested this documentation from Tesla and will be able to provide all the service reports and communication as a follow-up.

56 Adaptive Cruise Control problem of the 2026 Tesla Model Y

Failure Date: 11/15/2025

While driving in rain at night, the vehicle’s automated driving system attempted to make a turn at an intersection near active train tracks. Instead of remaining on the roadway, the system steered the vehicle directly onto the train tracks, where the vehicle became stuck between the tracks and the paved road surface. All four tires were damaged, and the vehicle could not return to the travel lane under its own control. If a train had been approaching, this situation could have resulted in a severe or fatal collision. I had to manually reverse the vehicle a significant distance to return to the roadway. The malfunction appeared to result from the automated driving system misidentifying the roadway under rain and low-visibility conditions. This suggests a recurring risk for any vehicle using the system at this location in similar conditions. The safety issue has not yet been inspected or confirmed by the manufacturer. No warning lights or alerts were displayed prior to the incident. The affected components and system are available for inspection upon request. I also have dash-cam video of the incident documenting the event.

57 Adaptive Cruise Control problem of the 2024 Tesla Model Y

Failure Date: 11/12/2025

I am writing to report critical safety issues I’ve experienced while using Tesla’s full self-driving (fsd) software version 14. 1. 3. The recent update has introduced several dangerous behaviors that were not present in previous versions. One issue occurs frequently on neighborhood roads: the vehicle performs sudden emergency braking for no valid reason. For example, during one drive, it abruptly stopped because a few leaves blew across the road. There were no pedestrians, vehicles, or real obstacles present. These false-positive braking events are alarming and could easily cause a rear-end collision. An even more concerning issue arises during highway driving. The car now repeatedly swerves partially into adjacent lanes—without signaling—and then abruptly returns to its original lane. This happens constantly, even in light traffic, and it did not occur in previous versions of the software. This erratic behavior is incredibly dangerous and could easily cause sideswipe accidents or create confusion for surrounding drivers. It is clear that version 14. 1. 3 is a regression from earlier versions. The system’s decisions are more erratic, less confident, and frequently unsafe. I no longer trust the fsd to operate reliably in environments where it previously performed well. I urge your agency to investigate this software update as it presents a real and growing hazard on public roads.

58 Adaptive Cruise Control problem of the 2026 Tesla Model Y

Failure Date: 11/05/2025

Fsd was unable to avoid object in road, may be due to how the adaptive headlights work as I was unable to see the object as well fsd/adaptive headlights may may it hard or impossible to see objects on road at night no in the process of a insurance claim no.

59 Adaptive Cruise Control problem of the 2024 Tesla Model Y

Failure Date: 10/27/2025

Recently Tesla released it's latest version of fsd, v14. 1. 4. One of the key features is the revamping of the driving modes: sloth, chill, standard, and mad max. Tesla also removed the ability to manually increase or decrease the speed of the car. This is a problem. Let me illustrate it with a real-life example. Yesterday I was driving of a 40 mph road and the car correctly set the speed. I was using the standard mode so the car allowed an overage of around 10% so the actual speed was 45 mph. In our area this is typical for most drivers. As we entered a village, the posted speed limit was changed to 30 mph. The panel was perfectly visible and readable. The car did not register it and continued at 45 mph. I changed to mode to "sloth" and the car decreased its speed to 40 mph but I was still 10 mph above the legal speed limit. I came across a second 30 mph panel and again the car "ignored" it. Because I did not have the ability to manually reduce the speed of the car, I had to disengage fsd and drive the car by myself. Tesla claims fsd must be supervised. Fine. But removing the ability to manually change the speed of the car should be a requirement not a design preference.

60 Adaptive Cruise Control problem of the 2026 Tesla Model Y

Failure Date: 10/27/2025

Tesla fsd v14. 1. 3 feels unsafe for the typical “average” driver because it no longer allows users to set a maximum speed limit offset when using the standard driving profile. In fsd v13, drivers could specify a max speed offset—such as 10% or 15% above the posted limit—when fsd was enabled. However, this option is no longer available in fsd v14. As a result, fsd v14 in the standard profile often speeds on highways and makes aggressive lane changes to pass slower vehicles. This behavior feels unsafe and stressful for most everyday drivers. Tesla should restore the ability for each driver to set their own comfortable max speed limit and reduce the aggressiveness of lane changes.

61 Adaptive Cruise Control problem of the 2024 Tesla Model Y

Failure Date: 10/27/2025

New update to asds software allows the vehicle to do 15-25+ over the speed limit and no ability to control. This is unsafe and Tesla took away the ability to control speed. Either engaged or not, this is completely unacceptable and they seem set on this being the only way to go.

62 Adaptive Cruise Control problem of the 2026 Tesla Model Y

Failure Date: 10/26/2025

Tesla fsd issues: 1. Phantom braking sudden to a full stop for no known reason in the middle of the road, throwing my dogs into the floor and the car stopped completely on the highway. If an infant had been in the car ina car seat, their neck could have been broken 2. Sudden jerkiness when making turns 3. In one case the car suddenly changed lanes and was a close encounter. 4. Fsd system is now completely non-functioning. 5. These issues started about about 1 month ago and worsened in the past 1 week after the latest software update. Tesla premium connectivity navigation issue 1. Instead of taking me on main roads to my destination, it has been taking me down rural, isolated dirt roads. In one case I was directed to a dirt, logging road, isolated and dangerous terrain. I had to turn around in a secluded area and the navigation system kept directing me to dirt roads, although main roads were close by once I opened my iphone for directions. 2. In lynchburg, va the navigation directed me towards an exceptionally steep downgrade to the river and would have been a catastrophe 3. These issues started this weekend 10/24 - 10/26/25 door locks 1. Door locks respond occasionally and there have been times I left the car assuming it would lock but it had not. There is no rhyme or reason to this. 2. This issue started 10/25/25 I am following up with Tesla next but thought you should be made aware. I did the recent Tesla software update and things just got worst.

63 Adaptive Cruise Control problem of the 2024 Tesla Model Y

Failure Date: 10/24/2025

My 2024 Tesla Model Y hit a parked vehicle on the right side of the street during fsd self driving. The car suddently slanted to the right and hit the parked vehicle. During fsd drive, it did not give any warning before the accident. My dauther was injured on her face. Clearly the new version fsd v14. 1 software is very defective. I am located in san jose, CA.

64 Adaptive Cruise Control problem of the 2026 Tesla Model Y

Failure Date: 10/21/2025

Upon purchase of the vehicle, unlike previous models and versions of the software - the vehicle’s speed limit control was incapable of being set - instead, using fsd, you had to select from percentage based offsets - which were frequently ignored and would still go much higher or much lower than the percentage value set. The owner of the vehicle was unable to say limit to only 10 over the speed limit; instead it was percent based and not reliable. In addition, more than a third of the time - the speed limits in the infotainment system did not match the posted speed limits. Sometimes, in the middle of a highway - it would randomly go from 55 to 25, posing a significant threat hazard when using the fsd or cruise control system (which is something Tesla charges extra for access to) causing the vehicle to immediately decrease speed when other vehicles behind are getting up to speed and not expecting a vehicle to randomly slow down excessively. Additionally, when you manually override the speed limit control, or the system does, the user interface hides this limit so the driver is unaware of what limit of speed it is set to. These issues were already bad enough, but just yesterday my vehicle was pushed a software update that dramatically reduced the performance of fsd, and now I am unable to manually control the speed limit at all in fsd. This was a regression from purchase, when a scroll wheel at least allowed me to manually set the speed limit or correct it when it was wrong. Now, that feature has been removed and instead there’s a duplication of fsd profiles (left/right on the right scroll wheel does the same as scrolling up/down). And continuing this trend, the driver is incapable of seeing what the speed limit is set to because it’s hidden from the user interface. In addition, the driving behavior for fsd has significantly regressed from before the update. Cruise control’s most basic functionality should be to set a speed limit. Now this feature has been removed.

65 Adaptive Cruise Control problem of the 2026 Tesla Model Y

Failure Date: 10/13/2025

On the day of the incident, I drove my vehicle into the charging station and activated the Tesla fsd autonomous driving and automatic parking functions. During the automatic parking attempt by the vehicle, the system exhibited the following severe loss of control behaviors: 1. The vehicle automatically collided with the vehicle in front without any human operation. 2. It paused for about 1 second after the collision. 3. Then, the vehicle suddenly accelerated in reverse at high speed, again without any driver operation. 4. It directly hit another Tesla that was charging behind my vehicle. The entire process is fully executed automatically by the vehicle system. I cannot intervene or stop the system through the steering wheel or brakes. Ii. Severe security risks when the accident happened, my friend was sitting in the passenger seat. If the vehicle had moved a few more inches, it could have caused serious injury or even a life-threatening situation. This system failure is a combination of sudden unintended acceleration (sua) and the loss of control in autonomous driving decision-making, posing a significant systemic risk to public traffic safety. I immediately contacted Tesla and sent a complaint letter to the north carolina consumer center. They accepted my complaint and sent an email to Tesla, but it has been over twenty days and I have not received a response from Tesla.

66 Adaptive Cruise Control problem of the 2024 Tesla Model Y

Failure Date: 10/12/2025

Tesla removed the speed limit offset feature in fsd version 14. 1. 4 and now only uses speed profiles called sloth, chill, standard, hurry, and mad max, and this has made my car extremely unsafe to drive. The problem is that these profiles make the car go either way too slow or way too fast and I cannot adjust it to match actual traffic conditions anymore. To make matters worse, the speed limit detection is broken and frequently shows the wrong speed limit for the road I am on. When I use sloth, the car never goes over the detected speed limit no matter what, so if the system thinks I am in a 35 mph zone when I am actually on a 55 mph highway, my car crawls along at 35 while traffic is flying past at 60-70 mph. I have people tailgating me, honking, flashing their lights, swerving around me dangerously, and I have almost been rear-ended multiple times because my car is going so much slower than everyone else. Without the ability to set a maximum speed offset, I am stuck going whatever speed the broken detection system thinks is right. If I switch to standard, hurry or mad max to try to keep up with traffic, sometimes the car goes way too fast for the actual conditions or blows through school zones and residential areas at unsafe speeds. I cannot fine-tune the speed anymore to drive safely with the flow of traffic. I am forced to either be a rolling roadblock and risk getting hit from behind, or use an aggressive profile that might go dangerously fast. This happens every single time I use fsd now and the combination of broken speed limit detection plus no manual offset control has created a seriously unsafe situation. I feel endangered every time I drive and I am genuinely worried about causing or being in an accident.

Reporting fsd incident on 10/08/25 approx around 8. 15 pm I was going on I-90 towards western mass / u mass amherst using fsd on 10/08/25 on I-90 road work was ongoing and it was 2 lanes. All the vehicles started going in the right lane as left lane had cones . Left lanes cones were tapering on its way ahead. My Tesla fsd chose the left lane which I would not choose as I saw at the distance cones were tapering to form a single lane . Tesla fsd drove in left lane and as it noticed cones tapering into single lane fsd acutely cut into the right lane in front of the of the truck at a very very narrow margin . Once the right lane , fsd asked me to take control of the car. From there till u mass amherst I could not use fsd . This was scary experience. I wanted to report using voice command but I got busy . Please you must have recording of the event. No body was hurt no vehicle damage just wanted to make aware about fsd.

My vehicle’s auto-high beam system does not properly recognize other traffic. It specifically fails to substantially dim the high beams when approaching oncoming vehicles or when behind other traffic on roadways. I have reported this to the manufacturer and attempted to have the dealership fix this on multiple occasions. The dealerships insist that the vehicle dims the required number of pixels in the headlights to not blind other drivers. However, this does not appear to be effective as other drivers that I have followed behind reported that they were being blinded by my highbeams while I was behind them. There is a notable difference between the highbeams and the low beams which the car fails to substantially adjust for when using this required feature to utilize the self driving/auto pilot feature.

While on a two lane road, my car decided to go around the car in front of me into on-coming traffic while in full self-driving mode. I had to jerk the car to the right to prevent a head-on collision!!!! I missed the on-coming vehicle by seconds!!! this was terrifying!.

I would like to formally report several incidents I have experienced with my newly purchased Tesla Model Y. I acquired the vehicle on [xxx], collected it from washington d. C. , and drove it back to houston between September 20 and 21. Prior to my return journey, I conducted a test drive. During this drive, at dusk, I engaged full self-driving (fsd) mode. The vehicle stopped appropriately at a traffic light; however, once the light turned green, it moved forward but veered into the yellow safety buffer zone located between the lanes of opposing traffic. I intervened by manually steering the car back into the correct lane. A similar occurrence happened in washington d. C. While attempting a left turn under a highway overpass—the vehicle again crossed into the yellow lines. These incidents suggest that the fsd system did not reliably detect the yellow lane markers. On the weekend of [xxx], during my drive to houston, I primarily used fsd. While navigating a road construction zone, the system failed to recognize large safety cones (yellow columns) and nearly collided with them. Fortunately, I was attentive and promptly took control, braked, and changed lanes to avoid an accident. This demonstrated the fsd’s inability to identify these safety markers. On Tuesday, [xxx], I drove the vehicle to work and returned home using fsd. As I exited the highway onto a ramp merging with frontage lanes, I observed that fsd did not reduce speed appropriately and nearly made contact with vehicles on the frontage road. This indicates that the system was unable to interpret the ramp as a short section intended for deceleration and safe merging. On [xxx], while returning home in the evening after work, I used fsd due to light traffic. The vehicle navigated turns and stops satisfactorily and paused roadside before my house. When I resumed manual control to park, the vehicle suddenly became unresponsive, accelerated onto my front yard, struck the flower bed stones, information redacted pursuant to the freedom of information act (foia), 5.
