Adaptive Cruise Control problems of the 2024 Tesla Model Y - part 1

While driving on the highway with Tesla fsd engaged, the vehicle activated the right turn signal and began steering right as if taking an exit. There was no exit ramp, gore area, or valid right-turn path at that location. I took manual control to prevent the vehicle from leaving the highway/entering the shoulder. I believe this could have caused a crash if I had not intervened. I have dashcam footage of the event.

Whenever the self driving feature is disengaged, a pop up menu is forced into the user asking for a reason for the disengagement. The user is forced to submit a response for the pop up menu to go away. This menu shifts sections of the screen around and can cause distractions due to the user looking for specific information that is typically there but is not due to the pop up menu.

Vehicle: 2024 Tesla Model Y date of incident: xxx location: southbound xxx express lanes near the [xxx]/[xxx] exit split in [xxx]. At the time of the incident, Tesla full self-driving (fsd) supervised was engaged. I was traveling in the express lanes and intended to remain in the express lanes. I was not attempting to take any exit. As the roadway approached a lane split/gore area, the vehicle began steering toward the striped boom barriers that prevent drivers from going into oncoming traffic, rather than remaining in the travel lane. There were not impending impact alerts or lane deviation alerts. There were no unusual weather conditions, and I did not observe any road conditions that would have made the lane path unclear to a human driver. As soon as I saw the vehicle veering into the boom barriers, I intervened by taking control of the steering wheel. The system disengagement alert/chime occurred only after I took over. Despite my intervention, the vehicle made contact with the boom barrier assembly. The impact caused significant damage to the windshield and driver's side door frame. Glass entered the passenger compartment. My infant child was in the vehicle at the time. Fortunately, no injuries were sustained. Tesla dashcam footage of the incident was preserved and is available. A claim was opened with Tesla insurance, and I was advised to submit a vehicle malfunction report for review of vehicle telemetry and fsd operation during the incident. After the collision I maneuvered the vehicle back into its lane, exited the toll highway and parked at a nearby shopping center to assess our injuries the vehicle. While there, another Tesla parked near me, and the driver had experience the same exact situation while his Tesla was in autodrive. I am requesting investigation into whether the vehicle's driver-assistance system improperly tracked toward the boom barriers rather than remaining within the intended travel lane.

On the evening of June 3, 2026, while driving on the I-575 express lanes in cobb county, georgia, the vehicle’s autopilot/driver assistance system malfunctioned and steered the vehicle into the express lane boom barrier. The boom bar struck the windshield, causing catastrophic windshield failure with glass imploding into the cabin. Glass shards covered the driver’s seat, floor, and dashboard. The driver sustained glass puncture wounds to both forearms and forehead, as well as neck, back, and right arm soft tissue injuries. Component failed: autopilot/adas system. Vehicle is available for inspection. Tesla was notified directly at time of incident. Insurance company has been notified. Sr-13 filed with cobb county. No warning lamps or messages appeared prior to the autopilot malfunction. The root cause of the windshield damage was the autopilot system failure, not driver error or external road debris. Photographic documentation of vehicle damage and driver injuries exists.

The Tesla autosteer (equivalent of adaptive cruise control) failed to brake on seeing the car ahead braking. In the 5 seconds before impact, the car ahead had started braking. The autosteer did not brake for the first 3 seconds and then it asked me to take over 2 seconds before collision. It did not apply automatic emergency braking causing me to rear end the car ahead of me on the freeway at around 30mph this is supposed to be a safety driver assist feature which instead was the primary cause of the accident. The take control was too late to avoid collision. This is a serious safety issue.

I am reporting a software-induced driver distraction defect in Tesla’s full self-driving (supervised) system, specifically the post-disengagement “why did you intervene?” dialog introduced in software 2026. 2. 9. 8 and modified in 2026. 2. 9. 9 and 2026. 2. 9. 10, running fsd v14. 3. 2. Every time the driver disengages fsd via steering, brake, or accelerator input, a modal dialog appears on the center touchscreen asking the driver to categorize the intervention. It presents four options (navigation, preference, discomfort, critical) plus a voice memo prompt. The dialog cannot be dismissed or deferred. It remains on screen indefinitely until the driver reads the prompt and taps a selection. This creates a serious safety hazard: the dialog appears the moment the driver has resumed manual control, often in response to an unsafe fsd action requiring immediate attention to the road. Forcing the driver to read text and make a multi-choice touchscreen selection during this high-cognitive-load transition directly conflicts with NHTSA’s driver distraction guidelines for in-vehicle devices. The dialog occupies a large portion of the center display and obscures the navigation map and surrounding-vehicle visualization, removing situational awareness at the moment it is most needed. Because it cannot be dismissed, drivers are coerced into touchscreen interaction while driving, including in active traffic, intersections, merges, and lane changes. The forced-choice design also incentivizes drivers to tap any option to clear the screen, defeating the stated data-collection purpose and increasing eyes-off-road time. Tesla provides no setting to disable this dialog. I request NHTSA investigate this as a driver distraction defect and require Tesla to provide a dismiss option, defer the prompt until park, or remove the forced-interaction requirement. I am the vehicle owner and experience this on every fsd disengagement.

Hello, I am not writing about a specific incident, but rather wanted to alert the NHTSA to a potentially dangerous development with Tesla's full self-driving (fsd) technology. In the latest software update being pushed to owners, Tesla now forces drivers to provide feedback if they disengage the fsd system for any reason. This feedback comes in the form of a box on the screen and it cannot be closed. You cannot interact with any part of the vehicle infotainment system until you complete the feedback. I believe that this can cause safety issues, especially in a stressful situation if someone is trying to access the car's map system, for example. Even in normal situations, the driver would be required to read the options and make a selection on the screen - while still driving. I would highly recommend the NHTSA look into this, as I believe this is a very shortsighted policy that will needlessly endanger drivers, other drivers, pedestrians and everyone on the road. To be clear for form purposes: I am not writing about a specific incident, but I am submitting this information via this form because I do not see a general information form.

Nhtsa complaint narrative — safercar. Gov vehicle: 2024 Tesla Model Y component/system: full self-driving (supervised) software, version 14. 2. 2. 5 on March 14, 2026, at approximately 5:22 pm, a 2024 Tesla Model Y was traveling on u. S. Route 3 in franconia, new hampshire, at approximately 45 mph within the posted speed limit. The vehicle was operating with full self-driving (supervised) software version 14. 2. 2. 5 actively engaged. Three occupants were present in the vehicle, including two minor passengers. All occupants were properly restrained with seat belts. Component/system that failed: the full self-driving (supervised) system, version 14. 2. 2. 5, failed to safely detect and respond to a snow-covered road surface. The system lost control of the vehicle upon encountering a snow patch on the roadway, causing the vehicle to strike a tree. The fsd system is the primary failed component. The vehicle has been towed and is available for inspection upon request. How safety was put at risk: the fsd system was in active control of the vehicle's steering, braking, and acceleration at the time of the failure. The system provided no auditory alert, no visual warning, and no driver takeover request prior to the loss of control event. The failure occurred without any warning whatsoever, leaving insufficient time for the driver to intervene and prevent the collision, despite the driver actively supervising the system in full compliance with Tesla's own supervision requirements. Three occupants were placed in immediate risk of serious injury or death. The vehicle struck a tree and was totaled. Emergency services responded and evaluated all occupants on scene. An official police report was filed. Prior warning lamps, messages, or symptoms: none. The fsd system issued zero warnings — no auditory alerts, no visual prompts, no haptic feedback, and no takeover requests — at any point prior to or during the loss of control event. The system was operating normally by all displayed indicato.

Tesla's full self-driving software continues to malfunction. On January 30th at 9:50 a. M. Mountain standard time I was parked at work and discovered my vehicle was left unlocked with a partial window unrolled. This was my first indicator of many faulty problems signaling the vehicle was not operating properly. The vehicle has a proximity sensor via bluetooth that locks and unlocks the vehicle on the owners approach was not properly working. On January 31st I experience a catastrophic failure with the software of the vehicle as I was locked out of my vehicle after utilizing summons feature that stopped the vehicle in the middle of the intersection obstructing traffic. Police arrived on scene within 30 minutes and we were unable to put the car in any gear to either drive the vehicle or place it in neutral to roll it out of the way. I have detailed video of the incident which is a better accounting of the incident on both occasions, the 30th and 31st of January. This is roughly the third or fourth occasion of Tesla's system producing a catastrophic failure resulting in damage to the vehicle or property damage.

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.

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.

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.

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.

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.

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.

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.

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.

Traveling today using the cruise control function in Tesla Model Y, the car took over the control of the car and applied braking for no clear reason. Was going 70 miles an hour, had been using the cruise control for about 30 minutes when incident occurred. There were semi trucks in the slow lane, I was in the fast lane. There were no vehicles in front of my car. The car suddenly lunged forward as the brakes were automatically applied. Simultaneously, the steering wheel began to jerk back and forth causing the car to veer back and forth. Vehicles around me began braking as well to avoid rear ending my car and to avert hitting my car as it veered back and forth. I had to fight the steering wheel in an attempt to pull it off the active roadway and then the car suddenly gave all control back to me at which time I was able to disable the cruise control and take full control.

Three different occasions, while utilizing adaptive cruise the car applied all breaks, causing me to lunge forward with the car coming to a complete stop. I did not see anything that would had caused the car to apply the breaks and the camera's did not record any obstacle. This was brought to the Tesla dealerships attention and I was told there is nothing that can be done about it. If I had not been wearing my seat belt, the potential emergency braking could had resulted in me sustaining a blunt force impact to my chest with the steering wheel, not to mention a possible motor vehicle accident with the vehicle behind me. I did look through the manual and there is no way of me turning feature off or lowering to a warning versus a suddent stop.

I was driving on a three-lane highway (I-495) using the adaptive cruise control (autosteer) when I suddenly noticed the car to my right dangerously veering toward my vehicle. In an attempt to change lanes to the left, my car wildly overcorrected to the left, nearly sending me into the highway median, followed by another overcorrection to the right. The steering wheel felt almost uncontrollable. Luckily no collision.

After update 2024. 38. 2 they introduced a "active curve assist" which can't be disabled while using the cruise control. This has caused the car to excessively brake (70mph to 45mph), a couple times while a vehicle is following resulting in a near rear end collision and has created dangerous situations.

When using fsd, I've noticed that on occasion at a red light, the car will start moving, albeit very slowly, a fraction of a second before the light turns green. I've assumed the car was watching the traffic lights from the other direction using its cameras. So on the [xxx] when this happened, and the car started moving I let it go thinking the light was about to turn green. But I was shocked that the car drove through the red light. Admittedly there were red lights in all directions. I know I'm supposed to be keeping control but it was so shocking that by the time I reacted the car was already in the intersection so I let it go. I downloaded a recording of it. [xxx] information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

Tesla full self driving v13. 2. 2 attempted to make a left turn while having a red light. The vehicle successfully came to a complete stop due the red light but once traffic cleared the intersection it attempted to proceed with the left turn while still having a red light. I immediately took over preventing the car from entering further into the intersection.

The fsd feature for which we have paid in full to Tesla does not work. No cruise control and no assisted steering control or cruise control works. As per their service department, ap4 car computer has internal short and camera can not communicate for above mentioned features.

Cameras stopped working which made all of the safety functions and gps stop working as well.

The car lost all adas functions, and gps on the onboard navigation system. In addition. It can't use regular cruise control and it does not have rear view mirror blind spot warning capability any more. This all happened when the car attempted to install the "holiday" updated from Tesla automatically around 11/29/24 .

On 12/16/2024 my vehicle received software update 2024. 39. 15, after installing the update I went to the grocery store and noticed nothing was working in the car except basic driving functionality. Cameras were showing up as a black screen. Tacc, aurosteer and fsd supervised were no longer working as well as aeb,fcw,bsm,ldw,lkas and the gps had me in the middle of the ocean, headlights on during broad daylight. I informed a service center by my home and they simply didn’t care, I took it to another service center 50 minutes away and they took two days to do repairs and diagnostics, I was told the computer had shorted out and the technician replaced the car computer and ai4 (hw4) computer system which runs safety features. A software update physically pushed from Tesla should not be shorting out computers on its vehicles, I heavily rely on the cameras and safety features since living in a state where nobody knows how to drive (lol). I hope my vehicle is fixed and this issue doesn’t persist anymore.

Around Dec 16 all cameras in my 2024 Model Y Tesla stopped working and it has not worked since that date. This affects many systems, the most important of which is that I now have no rear backup camera. I believe vehicle manufacturers are required to have functioning back up cameras. I notified Tesla service on 12/16 and was told there was a known computer hardware problem which would cause my incident. Tesla service told me they were unable to obtain the needed computer replacement for a month at least. They informed me there was no safety risk, but I disagree since I don’t have a functioning back up camera, nor lane change camera assistance. Also the display panel is very dark and impossible to read most of the time, posing another safety concern. Why has Tesla not issued a public statement about this problem, and why has NHTSA not mandated a formal recall?.

Vehicle information: • make: Tesla • model: Model Y • year: 2024 description of the problem: after a software update pushed by Tesla, the ap4 computer in my 2024 Tesla Model Y shorted out, causing a complete failure of all systems controlled by this computer. The following safety-critical and driver-assist features have become non-functional: cruise control (adaptive or otherwise) back up camera forward collision warning lane departure warning lane keeping assistance blind spot warning parking collision warning full self-driving and auto park features cameras required for autopilot functionality additionally, because the gps system has failed, the vehicle’s navigation system is inoperable. This impacts Tesla’s unique route planning feature that sets up supercharger stops during long journeys. Without a functioning navigation system, I cannot properly plan my travel or locate charging stations, which severely affects the usability of the vehicle. Safety concerns: the failure of these systems, especially safety features like forward collision warning, lane keeping assistance, and blind spot monitoring, puts both the driver and others on the road at risk. Losing access to safety-critical functions after an update is unacceptable and poses a serious danger to vehicle occupants and surrounding traffic. Incident details: • the issue occurred immediately following a software update. • Tesla pushed the update remotely without providing any warning or indication of potential risks. • the failure appears to be related to a hardware short in the ap4 computer, directly caused or exacerbated by the update. Desired outcome: • a thorough investigation into Tesla’s software update process and its effect on vehicle hardware and safety systems. • a resolution that prevents similar failures in other vehicles and ensures system updates do not compromise vehicle safety or critical functionality.

Navigation is frozen. No cameras work. No full self driving features work. No cruise control.

After a recent software update - all cameras/sensors/cruise control/adas systems are no longer functioning.

Bought my Tesla Model Y on [xxx]. Exactly one month later on [xxx] I start my car to find that none of the cameras are working. This means autopilot, cruise control, rear camera, blind spot monitoring and many more safety features are completely down. In addition the gps does not function meaning my car is not trackable and maps don't work, another safety concern and main reason we bought the car. This is a widespread issue that Tesla service centers have been informed about from Tesla that it is a bad computer that needs to be replaced - in a 1 month old car. My only option is to wait for a computer to be assigned to me which is at earliest on January 21st of 2025, almost 6 weeks without a fully functioning brand new $46,000 car with only 1400 miles on it. Tesla are also unwilling to make any kind of restitution such as a loaner car, or a refund for the full self drive and connectivity packages I just purchased but cannot use as my car is broken. Here is a link to an article showing this - [xxx] information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

All the cameras on the vehicle were unavailable starting today (12/08), including the rear view camera. The vehicle was not drivable and no cruise control was working.

All of the cameras on the vehicle are no longer working after the latest update. This means all sensors (even as simple as windshield wipers) do not work. All driver safety assistance does not work.
