Adaptive Cruise Control Problems of Tesla Model Y - part 2

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.

* what component or system failed or malfunctioned, and is it available for inspection upon request? fsd. It is available upon request. * how was your safety or the safety of others put at risk? over the course of the last two months since the last fsd update (currently on v12. 6. 4), at least 20 times the vehicle has not properly stayed in the lane under certain circumstances listed below. These circumstances are always the same and it is repeatable and dangerous as the vehicle would have crashed into the center median if I had not intervened. Repeatable conditions: * 79 mph * low curvature highway at highway speeds when turning to the right only. * fsd version 12. 6. 4 with software version 2026. 14. 6 is engaged and in assertive mode. * has the problem been reproduced or confirmed by a dealer or independent service center? Tesla wanted $1k in order to reproduce and diagnose the problem, so I declined. * has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? same as above; Tesla wanted $1k in order to reproduce and diagnose the problem, so I declined. * were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? none of the safety systems fired, including lane departure warning or steering correction. Fsd would not have veered out of the way of the median.

Whenever I cancel fsd in this Tesla for any reason, a highly distracting ‘forced feedback’ panel pops up on the single information screen, obstruction critical information. It only disappears when I select one of 4 feedback options, blocking my information screen view all that time. I am a regular driver, not a trained beta tester.

Tesla recently pushed a software update that introduces a major, unavoidable driver distraction right at the most critical moment of driving: the exact second you take manual control back from full self-driving (fsd).   whenever you disengage fsd, a mandatory, multiple-choice survey pops up on the center touchscreen asking why you took over. Unlike previous versions where this would disappear after a few seconds, it now stays on the screen permanently. There is no close button, and it does not time out.   this causes two clear safety hazards while driving: 1 it blocks the screen: the popup actively covers up part of the navigation map and basic screen controls. If you are trying to navigate a tricky intersection or see your route right after taking over, you can't see the map clearly because this giant survey is blocking it. 2 it forces you to look away from the road: because the prompt never goes away on its own, it forces the driver to physically look down, read the small text options, and tap the screen to clear it. Forcing a driver to do a multiple-choice survey while actively managing a manual takeover in traffic is incredibly dangerous. Tesla should not be allowed to use a mandatory, permanent ui popup to collect data while a vehicle is actively moving. It is a severe visual and cognitive distraction at the exact moment a driver needs to be 100% focused on the road. Please investigate this software design and require Tesla to add an automatic timeout or a quick-dismiss button that doesn't require driver interaction.

Adaptive cruise control slams on the brakes at highway speed alleging “curvature assist” on flat, straight roads. Dealer replaced firmware and problem persists. Defect appears to be inherent to adaptive cruise control.

Driver used Tesla fsd (supervised) to park. The car (Tesla Model Y 2023) prepared to park and slowed down. Second before full stop, the car suddenly accelerated on its own without driver stepping on the accelerator. It went onto the curb and knocked over the fence and continue to drive full speed before driver braked hard and stopped the car. Video is available upon request.

On xxx I retrieved my 2023 Tesla Model Y (VIN: [xxx]) from Tesla motors nv, inc. ([xxx]) after their third attempt to correct a severe panel and component misalignment following a collision repair (invoice #xxx). The facility replaced major front-end structural components, including the front bumper beam (1687601-00-e), front subframe crush can (1109193-00-c), and cast front underbody left hand crush can (1608453-00-d). Tesla's official guidelines require a mandatory 3d structural measurement test whenever these specific cast aluminum underbody and subframe parts are replaced. The repair facility verbally claimed the damage was minor/cosmetic and that only a manual tram measurement was performed. However, a manual tram gauge cannot detect 3d frame twists or height deviations in cast aluminum components, making it wholly insufficient. As a direct result of this unverified structural alignment, the vehicle's front end remains warped. After the first repair, the headlamp shifted and protruded on the right side. After subsequent attempts to fix it, the left headlamp is again protruding outward. Because the structural frame is misaligned, the forward-facing cameras are out of calibration. Under autopilot, the vehicle exhibits dangerous behavior, including misidentifying a standard bike lane as an extended vehicle lane. Furthermore, the repair facility has since removed or hidden the conversation logs regarding these complaints, and I can no longer find the messages in the Tesla app. Operating a vehicle with unverified structural alignment and compromised driver-assist vision systems poses an immediate, severe safety risk.

At about 2:16 pm on Monday, 5/18/2026, I was driving southeast in the right lane of amaya drive from fletcher parkway in la mesa, CA, planning to turn right across the trolly tracks onto severin drive. There is an intermittent led sign indicating no right turn in the southeast corner of the intersection, just below and to the right of the ground-level stoplight, that illuminates when the trolley is passing so traffic going straight on amaya can still proceed. In the first street view pdf I uploaded, it is not illuminated. I had fsd engaged, and as I approached the intersection the no right turn led was illuminated. If I recall correctly, I assumed fsd would stop for the no right turn led; but instead, it continued to make the right turn. Luckily my son was in the right seat and yelled several times for me to stop, which I did—just a few feet from the crossing arm, which can been seen elevated in the middle of the second street view pdf I uploaded, and which was just coming down for the approaching trolley. By the time I got stopped, the crossing arm was fully down, and as noted above I ended up just a few feet from it, and would clearly and unequivocally have driven under and through it if I hadn’t braked suddenly. It’s clear that this was completely the fault of fsd either not reading or not being aware of the intermittent no right turn led sign. Since fsd clearly doesn’t read no right turn signs, particularly intermittent led signs, the solution seems to make this intersection no right turn whenever the light is green to pass through the intersection on amaya, although this will hold up the cars who would like to turn right when there’s no trolley approaching.

The latest Tesla autopilot software forces users to engage in an autopilot product survey after disengaging autopilot while driving in order to gain access to audio/radio controls. The survey is not dismissible without reading a complicated prompt and choosing a response, and it completely obstructs audio controls until you participate in the survey. The driver therefore cannot turn off music to listen for emergency sirens, pedestrians, or other potential safety cues while driving at any speed, unless the driver also takes eyes off the road to participate in the forced product survey. This is by design and affects all Tesla drivers who use the autopilot feature.

Whenever autopilot is disengaged by the driver, a pop up multiple choice question appears on the screen covering critical car information with no way to get past it except reading and answering the multiple choice question while you are driving. You have to take your eyes off the road to answer the question, it's about the dumbest most unsafe thing I've ever seen from a car company. Please require them to fix it immediately, and apparently a rule needs to be written that pop ups on cars are illegal.

I would like to report a serious safety concern regarding Tesla full self-driving (fsd) on hw3-equipped vehicles. My vehicle repeatedly performs sudden and aggressive braking while fsd is engaged, even when there are no visible obstacles, vehicles, or hazards ahead. In some cases, the vehicle slows dramatically or comes to a complete stop unexpectedly. This creates a significant rear-end collision risk, especially on higher-speed roads where surrounding traffic does not anticipate abrupt braking behavior. This issue has been occurring for approximately one year and appears to have worsened over time and Tesla hasn't released a single fds software update for over a year for hw3 vehicles. I recently brought my vehicle to Tesla service, paid for diagnostics/repair, and the issue still remains unresolved. I have also personally experienced the same behavior in another hw3 Tesla vehicle provided as a loaner from a Tesla service center, which suggests the issue may not be isolated to my individual car. Based on my experience, this appears to affect multiple hw3 vehicles operating with fsd enabled. The unsafe braking behavior causes surrounding vehicles to tailgate closely and react suddenly, increasing the likelihood of accidents. In my opinion, the current fsd behavior on affected hw3 vehicles presents a safety hazard for both Tesla owners and other road users. I believe this issue warrants immediate investigation. Until the root cause is identified and corrected, Tesla should consider disabling or restricting fsd functionality on affected hw3 vehicles to reduce the risk of accidents caused by phantom braking and unsafe autonomous driving behavior.

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.

The vehicle began experiencing repeated autopilot/fsd failures while driving. Symptoms included sudden autopilot disengagements, cruise control becoming unavailable, and loss of road visualization/navigation display functionality. The issue progressively worsened over time. The vehicle was first brought to Tesla service in 2025 for the same overheating-related concern. At that time, Tesla identified a coolant-related issue, topped off the coolant system, and returned the vehicle to service. However, the problem continued and gradually became more frequent and severe afterward. During the most recent service visit, Tesla diagnosed the hw3 autopilot computer as overheating due to a heat transfer failure between the autopilot board and cooling cold plate. Tesla stated that heat generated by the board could no longer be efficiently transferred to the coolant system, causing the autopilot computer to overheat. Tesla further advised that continued operation without repair could eventually impact additional vehicle functions, including the center display screen shutting off due to overheating-related failures. Given the loss of driver-assistance functionality and potential impact to core vehicle systems, I am submitting this report so the issue is documented as a potential thermal management or hardware reliability concern involving the hw3 autopilot computer system.

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.

My 2021 Tesla Model Y hw3 experienced complete failure of all cameras, gps, automatic emergency braking, and adaptive cruise control following the installation of software update 2026. 8. 6. 1 — the ota remedy update issued by Tesla for NHTSA recall 26v283000. The vehicle was fully functional prior to this update. The failure was confirmed and reproduced by Tesla's authorized service center. The service advisor confirmed in writing: "during the update, the computer failed to reboot properly. We attempted to perform a 12v reset but unfortunately it is still stuck in the boot loop state. " the autopilot ecu (primary/turbo a) is stuck in a permanent boot loop and cannot be recovered by software means. Safety impact: all cameras including rearview camera are completely non-functional. Automatic emergency braking and all adas features are disabled. The vehicle cannot safely detect obstacles or pedestrians. Gps navigation is frozen. Tesla has confirmed the computer requires replacement but is classifying it as a customer-pay repair citing expired warranty, despite the failure occurring during Tesla's own recall remedy software deployment. This vehicle meets every technical criterion of recall 26v283000 — hw3 hardware, 2021 Model Y, software version 2026. 8. 6. 1, complete camera failure — but does not appear in the recall VIN database. I am requesting NHTSA review whether this VIN should be included in recall 26v283000 or a related investigation.

Recurring camera and autopilot defect on a 2023 Tesla Model Y (hw3 with in-cabin camera, in scope for NHTSA recall 23v838). 7 service visits in 13. 5 months and ~14,000 miles of my ownership. Tesla verified the camera/autopilot defect in writing on 12/5/2025 and replaced the upper quad camera cover (p/n 1755687-00-b) and interior camera (p/n 1588124-s0-I). Same defect returned by 4/27/2026. On 4/28/2026 Tesla service issued a could not duplicate citing 'no log data showing signs of autosteer having an issue or any camera blocked alerts. ' but Tesla's own VIN-linked telemetry, which Tesla provided me via privacy portal data request, contains: 28 autopilot fault events on 14 of 27 retained days; 1 aborting event matching my report to the minute; and 17 highway-speed (>=50 mph) phantom-brake-class hard decelerations <= -0. 20 g. The worst event: 4/28/2026 at 2:12 pm edt, less than 90 minutes after Tesla returned the vehicle. Autopilot was in active_nominal state with cruise engaged at 63. 6 mph. System produced an unprompted -0. 252 g (-2. 47 m/s^2) deceleration. Driver was not braking; system was driving. Additional phantom brakes: -0. 297 g at 62. 9 mph on 5/2/2026; -0. 294 g at 70. 0 mph on 5/3/2026. Multiple take over immediately alerts without explanation. Camera blocked alerts in clear conditions. Driver-monitoring system flagged 'hands not detected' on 339 of 684 monitoring detection events during the 27-day window despite hands being on the wheel — the recall remedy mechanism is failing on this vehicle. This vehicle is in scope for NHTSA recall query rq24009 (open), investigating whether the 23v838 ota remedy actually fixed the underlying autosteer defect. My data is direct fleet-level evidence the remedy did not work on this VIN. Currently in active new vehicle limited warranty.

As a 100% t&p disabled veteran relying on advanced driver-assistance for mobility, I purchased a 2022 Tesla Model Y performance with hardware 3 (hw3), which was actively advertised and sold as possessing all necessary hardware for safe, autonomous operation. In practice, the vehicle suffers from safety-critical driver-assist defects—including unexpected disengagements and erratic system choices—due to fundamental hw3 processing and memory bandwidth limitations. Operating a vehicle marketed as autonomy-ready, but constrained by hardware incapable of handling complex traffic scenarios safely, forces constant manual intervention and creates an unacceptable collision hazard for a disabled driver.

I have been a user of Tesla's "full self driving" technology for four years. In one of the last major updates, the company removed the ability of the driver to manually set a "cruise control set point" to maintain a safe speed. Instead, they employed a new system with five "drive profiles," which included "sloth," "chill," "standard," "hurry," and "mad max. " the problem is that only two of those stay anywhere near the speed limit. "sloth" will go the speed limit, "chill" is about 2 mph over the speed limit, "standard" is about 7 mph over the speed limit, "hurry" is 12 mph over the speed limit, and "mad max" is probably 15-17 mph over. Sloth and chill will remain in the right lane, rarely passing another vehicle, but all the others will include lane changes. And all of these profiles do not maintain a safe following distance. Users have been complaining about the cars tailgating, sometimes as close as 3 car lengths at 70 mph. However, sometimes conditions necessitate slower speeds. . . Like work zones. I live near denver, and I-70 has a work zone that will be in existence until 2029. The car doesn't recognize the 45 mph speed limit, bouncing back and forth between 45 and 65. Fsd must be disengaged completely to follow the 45 mph speed limit. Which brings up the other problem. In many areas, the speed limits are wrong. In texas, there are areas where the speed limit is 70, and the car thinks it's 55. In new mexico, the speed limit is 70, but the car thinks it's 60. There is no speed profile that will maintain the legal limit. Tesla also has a mechanism that's supposed to allow users to report problems, but some of these I've been reporting for over three years. They refuse to tell us where we can update the information (grok says "here," tom tom, open street maps), and they are not fixing the speeds on the maps.

I am reporting two unresolved safety-related defects on my 2021 Tesla Model Y (VIN: [xxx] ) that occurred following paid service at Tesla's league city service center on 04/16/2026 defect 1 — computer and sensor system failure: the vehicle's onboard computer cuts in and out intermittently. Sensors fail during operation and the problem worsens significantly in high-temperature conditions. Tesla vehicles rely on their computer and sensor systems for core safety functions including collision avoidance, autopilot, and driver assist features. Intermittent failure of these systems while operating the vehicle is a safety hazard to the driver and the public. Defect 2 — glove box inoperable: the glove box does not open following Tesla service. The glove box in Tesla vehicles houses key vehicle documentation and is integrated into the vehicle's locking and security system. I paid $2,497. 50 for service on [06/16/2026]. Both defects were either caused or left unresolved by that service. I have notified Tesla service staff directly and followed up multiple times over more than four weeks. Tesla has not responded, has not scheduled any repair, and has not refunded my money. I am filing this complaint because (1) the sensor and computer failures present an active safety risk during operation, (2) Tesla has ignored all attempts to resolve this, and (3) public reviews indicate this is a pattern affecting multiple consumers. I request that NHTSA investigate and determine whether a safety defect investigation or recall is warranted. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

On April 16, 2026 around 7:30pm CT, I was driving a Tesla Model Y 2023 on I-35 near downtown austin. There was an extreme traffic jam, I turned on the auto pilot so it can cruise by itself without touching anything. It worked for a while, but suddenly it veered off to a lane on my right side, crashing into a large truck on the front right. This damaged all the front and passenger side fender. The car had to be towed. I used this feature many times in the past, it always stayed within the lane. This time it acted erroneously. This should not be marketed as "auto pilot" that people may lose their lives due to insufficient safety guard in the system. Fortunately the traffic was moving very slowly, no one was hurt in my case. I got all incident data downloaded from Tesla to prove its fault. Based on the data, the autopilot system had a fault starting at 12:50pm and 14:55pm, and was disabled at 15:59pm, but there were no warning as I turned it on when I drove on I-35 around 7pm. See the attached data file (highlighted rows, the claim system doesn't allow the original excel file to be uploaded).

The standard cruise control is extremely dangerous. The problem is what I hear is called ghosting. When driving using cruise, and there are no other vehicles nor any other objects such as animals or humans. The car will suddenly decelerate almost to the point of a complete if not overridden by manual takeover. I am under the impression that this is intentionally be done by Tesla, so that you will subscribe to their full self driving service. This can and will cause accidents in traffic.

I am reporting a serious safety concern involving my Tesla Model Y. While driving, the vehicle’s main center screen (mcu) suddenly failed and entered a continuous reboot loop. This resulted in the loss of critical driving information and controls, including navigation, camera display, and vehicle system status. The issue occurred without any warning and nearly caused a serious accident, as I was unable to safely monitor essential driving information. This failure made the vehicle extremely unsafe to operate. The problem appears to be related to a known mcu system failure affecting some Tesla vehicles. I am concerned that this issue may present a broader safety risk for other drivers. Please investigate this matter for potential safety defects.

I believed Tesla full self driving (fsd) was in effect. My Tesla proceeded at 35 miles an hour toward a stop sign and I had to manually stop the vehicle to prevent blowing the sign. It turns out that Tesla sent an email 2 days ago (April 7 2026) that notified me that fsd had been cancelled because my credit card was declined (I had to replace a card on April 7 due to a lost card). I did not see this email. There was no notification in the vehicle that fsd had been deactivated. When I thought I was engaging fsd, I was in fact engaging an autosteer mode with much lesser capabilities, essentially only acting like adaptive cruise control and lane guidance. Engaging this lesser mode is done in exactly the same fashion as fsd, and any driver using it in my situation would always assume fsd was active. This problem, if not corrected will absolutely cause accidents and potentially fatalities. Tesla needs to inform the driver via the head unit that fsd is not active in an obvious, unmistakeable way.

Running full service driving (fsd) v14. 2. 2. 5 on hw4. At skillman st & I-635 dallas TX, fsd attempted a wrong way turn into oncoming traffic instead of taking the correct leftmost lane. In the image attached instead of following the blue path Tesla took the wrong lane highlighted in red.

Driving using autosteer feature at 65mph on expressway, attempted to change lanes which caused the cruise control to suddenly turn off causing the car to begin braking hard with traffic behind it. Tesla’s new Model Y has combined the lane keeping and cruise control so if the lane keeping turns off the car suddenly brakes hard from the regenitive brakes. Lane keeping and cruise control should be two separate controls to prevent this issue.

Following a 25-day repair at a certified collision center due to an earlier accident, the vehicle's full self-driving (fsd) and active safety systems began failing. The vehicle repeatedly failed to keep speed and failed to stay centered in the lane. On March 25, 2026, while traveling at low speed on a public roadway with fsd actively engaged, the system failed to maintain a stable path and incorrectly steered the vehicle into a curb, causing property damage to the wheel. This failure put my safety and the safety of surrounding traffic at risk by executing an unpredictable steering maneuver that the active safety systems failed to prevent. The vehicle was taken to the manufacturer's service center twice with this specific complaint prior to the curb strike. The service center investigated and officially concluded that this was not a software issue, stating that they could do nothing else. They deferred the resolution back to the collision shop, citing likely camera/sensor physical misalignment from the 25-day body repair. The collision shop is now refusing to review the vehicle or inspect the hardware, claiming lack of visible exterior damage despite the internal service team stating this is a latent hardware alignment defect. The vehicle is currently in the same failing condition and available for inspection upon request. No warning lamps or error messages appeared on the screen prior to the failure or the curb strike. The symptom of unpredictable lane tracking first appeared immediately upon receiving the vehicle back from the collision repair earlier this year. Note: I have a formal data privacy request pending with Tesla to pull the exact chat logs showing their refusal to service this hardware defect. I will provide these to the investigator upon follow-up.

This is my 10th report; it relates to 2 issues I have reported before 1. The "phantom breaking" on cruise control that I have reported a few times previously has apparently been fixed on a software update, but we were not notified. I went in to santa fe Tesla where I took delivery of my vehicle and got into a discussion about my disappointments with this car, specifically the tires (see #2). I mentioned my past problems, including the phantom breaking. The man was dismissive and a bit defensive and asked if I'd made an appointment. I said I'd been told several times they hadn't figured out a software fix (and even Tesla employees were simply refraining from using cruise control, which is what I did). He said they "fixed it a while ago" and he's not had complaints since then. I tried cruise control on my 45 minute freeway drive and indeed, the problem did not occur. Interesting that they knew it was an ongoing problem, didn't deal with it, and didn't announce when they finally did fix it. I do not yet know if it is an ongoing safety problem for me but I'm planning to gradually increase my use of cruise control, since most of my driving is high-speed freeway driving. 2. I asked about getting warranty rebate for my original tires that have failed at 38k miles. He said I would have to pursue that through the distributor (american tire?) and that he'd only had 2-3 customers ever do that. He said most customers just pay for better tires. He offered to sell me another continental tire in the $400 range and implied that I could find tires through a tire store. I went to discount tire who can get me a rebate on only 1 of the 4 tires because it's down to 4/32" tread. The other 3 can't be warrantied until they reach 4/32". . . And I've already hydroplaned/slid on the freeway in a sleet storm with wet roads. The company knowingly provides inadequate tires and does not stand behind them. This is an unacceptable safety risk and a moral outrage.

I am filing a safety complaint regarding Tesla's removal of driver-controlled maximum speed in fsd (supervised), a change that has alarmed a significant number of Tesla owners and safety-conscious drivers. Previous software allowed drivers to set a precise maximum speed via the steering wheel scroll wheel while fsd (supervised) was active. Tesla replaced this with fixed "speed profiles" (sloth, chill, standard, hurry, mad max), none of which allow a driver to set a specific speed. Each profile operates at a programmed range relative to the posted speed limit. Even the slowest profile (sloth) has been observed exceeding the speed limit. The system also frequently misreads posted limits entirely. This is a serious safety regression. In winter conditions, a cautious driver may need to travel well below the speed limit due to snow or black ice. Previously, they could reduce fsd's max speed precisely. That is no longer possible, the system determines speed, and the driver cannot override it downward while fsd remains engaged. This concern is not isolated to just me. Online forums and Tesla owner communities have seen widespread discussion and frustration over this change, with many drivers expressing that it has made them feel unsafe and less in control of their own vehicle. Removing precise speed control from a supervised autonomous system directly contradicts Tesla's stated position that the driver remains responsible for safe operation. This is an ongoing issue and not limited to a single date for the "tell us the approximate date this incident occurred. " I request NHTSA: 1. Investigate Tesla's removal of driver-adjustable maximum speed in fsd (supervised); 2. Evaluate compliance with fmvss and driver control guidelines for automated driving features; 3. Require Tesla to restore precise, driver-controlled maximum speed settings.

Using Tesla fsd (full self-driving supervised) I drove home, approximately 120 miles, from a family visit. From previous experience with Tesla fsd, I knew that the navigation system would navigate into the incorrect of 2 driveways (left, instead of the correct driveway, right) leading to my parking space. Therefore, upon arriving at the building address I endeavored to take over full control by tapping break and manually turning to the right driveway, whereupon the steering wheel locked up completely and the car lurched forward crashing through the security gate and into a parked car directly in line with how the locked steering directed it. To the best of my knowledge, the car was removed to a salvage location where it was considered a total loss.

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.

Subject: Tesla self-driving / autopilot incorrect maneuver at intersection vehicle: Tesla (model: **)?software: full self-driving / autopilot (specify which was active)?date: __[xxx]__?time: _[xxx]___?location: _** carlos, [xxx] ____ (city, intersection or street) description of incident: while the vehicle was operating with Tesla’s driver-assistance system engaged, the navigation indicated the car would turn right at an intersection. As the vehicle approached the intersection and began the maneuver, it unexpectedly continued straight instead of completing the right turn. This caused the vehicle to enter the intersection in front of other vehicles that were stopped at another traffic light. I had to intervene to ensure safety. There was no clear reason for the incorrect maneuver, and the system behavior was unexpected and potentially dangerous. Additional information: •weather conditions: ___good weather _clear__ •traffic conditions: ___lot of traffic people getting off work___ •driver intervention: yes / no (explain briefly)yes heading straight to cars if I had not made a quick maneuver and turn the steering wheel. I would have crash hitting at least one or two cars. •dashcam footage available: yes / no no I am submitting this report so the event can be reviewed for possible software or safety issues with the driver-assistance system. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

Nature of defect: while operating full self-driving (fsd) at highway speeds, my vehicle exhibits involuntary lateral swerving — sudden, uncontrolled movement to the left and right without driver input. This behavior occurs repeatedly and unpredictably, posing a direct safety risk to the occupants of my vehicle and to other drivers. Tesla service diagnosed the root cause as a failed fsd computer and recommended full replacement at a cost exceeding $3,000. Crashes or injuries: none to date, though the behavior described above creates a significant risk of collision at highway speeds. Frequency: recurring during fsd engagement at highway speeds. Additional context: this defect was present during my vehicle's original warranty period. Tesla has been aware of this issue since my service visit and has not completed the repair. I have an active goodwill warranty request pending with Tesla that has gone unacknowledged for over two weeks. I am submitting this complaint because I believe this defect may affect other Tesla vehicles equipped with the same fsd hardware, and I want NHTSA to have a record of this failure mode.

Hello, I am reporting a safety issue with the full self-driving (fsd) system on my 2023 Tesla Model Y. The vehicle has been taken in for service four separate times for this issue. During these visits, Tesla service technicians were able to reproduce and confirm the problem. I have been explicitly advised in writing by Tesla service not to use the full self-driving system due to safety concerns and to use standard autosteer instead. While fsd is engaged, the vehicle exhibits dangerous and unpredictable behavior, including: crossing over double yellow lines into opposing traffic, driving significantly below the speed limit (e. G. , ~4 mph in a 25 mph zone), stopping in the roadway without any traffic or obstructions, swerving within the lane while attempting to maintain position, hesitation during turns, stop signs and at intersections. Tesla has attempted multiple repairs, including replacing steering-related components and multiple cameras across separate service visits. These repairs did not resolve the issue. At my last service visit Tesla has since indicated that the problem is likely software or firmware-related and that there is currently no available fix, with a recommendation to wait for a future update of an unknown timeline. If their statement is correct, this issue should be affecting every vehicle out there on the same software. At this time, I have been advised not to use a system that controls steering, braking, and acceleration due to safety concerns, and no timeline or resolution has been provided. I am submitting this complaint because the system behavior presents a potential safety risk to myself, passengers, and other drivers, and the manufacturer has not provided a current fix despite multiple confirmed service visits. I am attaching my last service invoice only in regards to this matter where they indicated to not use fsd, but I can provide other documentation showing the replacement of cameras and steering parts as well as videos if needed.

On Feb 25, 2026 my 2022 Tesla Model Y with only 25k miles on it suddenly stopped knowing where it was and almost drove me into a ditch. All cameras stopped working and the gps was stuck in the same wrong location. (service mode showed primary das ecu shows "ap in coreboot" and "status: init. " secondary b shows nominal. Features unavailable. Gnss shows 0 satellites in open sky. ) Tesla service said I was outside of warranty and “there is an internal processor issue with your autopilot system that will prevent updates from installing. The only solution is replacing the computer on April 9, 2026, 12:22,” I had had other computer related issues I brought up during regular service visits but weren’t recorded and I was told software updates would fix such delayed rearview camera upon startup, navigation volume resetting, headlights staying on for extended periods after exit, and lockout issues. I asked Tesla to document the specific failure codes which they never sent. They said “Tesla diagnostics are showing the primary autopilot computer is not booting properly, which is preventing cameras, software updates, and related systems from functioning. Because the computer is not initializing, a firmware reinstall will not complete successfully. At this point, replacement of the computer is the required repair to restore normal functionality. ” my car had a safety recall during its service appointment that they could not install software for unless I paid $3200 to replace computer. I had total loss of rearview camera (fmvss 111 violation) and loss of active safety systems (aeb/fcw), but Tesla refused to repair a federally mandated safety defect if I didn’t pay the full repair cost.
