36 Adaptive Cruise Control problem of the 2026 Tesla Model Y

Failure Date: 08/06/2026

While using fsd feature continuously for more than 45 minutes without stopping the system locks on to the previous road speed limit and freezes and the car ignores any new different speed limits and runs into fully rouge mode. . . And almost ran into a pedestrian without slowing down. Example - if road speed limit is 45 mph and car driving between 45-50 mph and when the road speed limit drops to 35 or 25 mph car continues to run at 45-50 mph. Ex2: if car running at 35 mph and later enters highway the car continues at 35 mph on highway where speed is 65 mph and likely to cause accident. The Tesla does not have any forum or email support or phone support to address this issue and says it will reset if I stop on highway and wait for 15 mins to reset and then start again. This occurs every time if you drive continuously without stopping ( turning off car) for 45 min or more.

37 Adaptive Cruise Control problem of the 2026 Tesla Model Y

Failure Date: 08/04/2026

On [xxx], at approximately [xxx], my 2026 Tesla Model Y (VIN: [xxx], delivered [xxx]) was involved in a rear-end collision while the full self-driving (fsd) system was actively engaged. The dashcam footage clearly shows "self driving" displayed in blue on the instrument panel at the time of the incident, with the vehicle traveling at 3 km/h in drive (d) mode. What failed: the fsd/adas system failed to detect the stopped vehicle ahead and did not apply braking or issue any collision warning prior to impact. Safety risk: the system had full control of the vehicle at the time of the collision. I was not manually operating the vehicle. The failure of the fsd system to respond appropriately caused a rear-end collision. Dealer/service confirmation: not yet confirmed by dealer. Incident occurred 2 days after vehicle delivery. Inspections: under review by insurance. Police report pending. Dashcam video evidence preserved. Prior warnings: no warning lamps or alerts were displayed prior to the collision. The fsd system gave no indication of the impending failure. Dashcam footage showing active "self driving" status at time of crash is available upon request. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

39 Adaptive Cruise Control problem of the 2026 Tesla Model Y

Failure Date: 08/02/2026

When using Tesla fsd, the car insists on following the car in front at an unsafe following distance…. Frequently less than 1 second behind it.

40 Adaptive Cruise Control problem of the 2026 Tesla Model Y

Failure Date: 08/02/2026

Tesla full self driving, installed version 14. 3. 6 is still unable to reliably obey speed limits. The driver of the car has no method of controlling full self driving to slow down the car to meeting the new speed limit. The full self driving (fsd) safety system must be disabled to regain speed control. Tesla claim in multiple social media posts that fsd is "significantly" safer than humans, but it will not reliably maintain accurate speed and instead will often attempt to significantly exceed the posted speed limits. Xxx driving through [xxx] on highway xxx heading west, with fsd controlling the car. The posted speed limit is 45, suddenly the car changed speed to 55, then faster. The only recourse is to disengage the fsd safety system to regain sensible speed. I have included one location, but this is a very widespread issue that covers much of [xxx], [xxx], [xxx] and [xxx].

41 Adaptive Cruise Control problem of the 2025 Tesla Model Y

Failure Date: 07/28/2026

The full self driving software does not allow the user to limit the maximum speed of the vehicle while in use. The car frequently drives 15-20 mph over the actual limits in typical driving modes with no ability for the user to safely and precisely restrict its speed to a more safe and appropriate level. The car may begin a journey at an appropriate speed, and continue at that speed for miles, but for no reason that is apparent to the user, the system may begin to accelerate beyond a safe limit. This makes the driving experience while using this software less predictable and compromises the safety of the user and others on the road. The user controlled speed limiting feature was previously available, and worked well, but was removed as part of an update to version 14. X of the software. An alternative that is being used, which is much less safe, is that users can restrict the speed of the entire vehicle such that its speed may never pass a certain level, under any circumstance, even if the accelerator is fully depressed (by the user). Once enabled, this feature cannot be adjusted or disabled while driving. Users are using this vehicle speed restriction feature to more precisely restrict the excessive and unpredictable speeding of the automated system because they are not given the ability to do so safely and precisely via other means.

42 Adaptive Cruise Control problem of the 2020 Tesla Model Y

Failure Date: 07/24/2026

This is about a 2020 Tesla Model Y, with hardware3 (hw3) full-self-driving (fsd) feature. The older hw3 fsd-enabled Model Y cars started getting the new "v14 lite" fsd updates recently - I got mine a few days ago. I immediately noticed a safety concern with the v14 lite. Previous versions of fsd allowed me to set the maximum speed that the car would drive in the fsd mode - I can adjust it using the "wheel button" on my right thumb on the steering wheel, and the car would not exceed the maximum speed I choose. However, after the update to v14 lite, the wheel button no longer controlled the maximum speed. Instead, it controlled the "speed profile" ("sloth", "chill", "standard", "hurry" are the options in my car). Regularly in highway driving, even in the standard mode, the car would speed up to go well past the speed limit, more than 10mph over the speed limit, seemingly to match the speed of the rest of the traffic (69mph on a 55mph highway). This felt very uncomfortable. I tried to adjust the max speed down like I was used to, but the car instead switched to a different profile, "chill", and rapidly slowed down to 4mph below the speed limit (51mph in this case=. The speed reduction was so sudden that it also felt dangerous (car behind me would have to break quickly to not hit me), and I didn't want to be driving well below the speed limit (also dangerous). Under "self driving" settings menu, there is also a feature called "speed limit", that used to allow you to set the "default" speed limit for fsd driving (for instance, +3mph above the speed limit). You can adjust it up and down with the right thumb wheel beyond that, but it set the default basic max speed limit for fsd. After the v14 lite update, the fsd completely ignores this speed limit, and happily accelerates well beyond that. Not it seems like the "speed limit" feature is simply for warning the driver to not exceed the pre-determined speed limit when controlling the car. Fsd simply ignores it.

43 Adaptive Cruise Control problem of the 2025 Tesla Model Y

Failure Date: 07/23/2026

My 2025 Model Y with stalks creates an unsafe driving condition. Under current software, enabling fsd forces a single-pull lockout that completely disables standard traffic-aware cruise control (tacc). (advanced driver assistance sytems) fsd routinely follows vehicles at less than a 1 second gap at 70-80 mph and attempts unsafe merges with tractor-trailers. Drivers must be allowed to drop to tacc to maintain safe following distances without being forced to entirely disable fsd while parked. Because the software removes the single-pull/double-pull distinction, the driver cannot downgrade the system to standard cruise control on the fly to establish a safe following distance. To stop the dangerous fsd behavior, the driver must completely disengage the system to manual control, as switching the underlying autopilot modes requires pulling over and shifting into park. Tesla customer support has refused to address this software-enforced safety hazard. Following too closely routinely happens on the interstate at highway speeds while using fsd. This safety issue occurs consistently during highway driving on major interstates at speeds between 70-80. The inability to seamlessly select a safe cruise control mode increases the risk of a high speed rear end collision.

44 Adaptive Cruise Control problem of the 2023 Tesla Model Y

Failure Date: 07/22/2026

I want to raise a serious safety concern with a recent Tesla software update related to full self-driving (fsd). When I disengage fsd, a prompt immediately appears on the main screen asking why I intervened, with selectable options. Here is the issue: when I take over from fsd, it is almost always because something requires my full attention in that moment. That is the exact point where I need to be focused entirely on driving, not reading or interacting with a screen. Introducing a pop-up at that precise moment creates a distraction during a potentially critical transition from automated to manual control. From a human factors and safety standpoint, this feels backwards: - the highest-risk moment is the handoff from fsd to driver - the system is adding cognitive load and visual distraction at that exact time - even if interaction is optional, the visual interruption alone pulls attention this is not just an annoyance—it has real potential to increase risk in already sensitive situations.

45 Adaptive Cruise Control problem of the 2024 Tesla Model Y

Failure Date: 07/18/2026

My car will randomly break while I’m driving straight on a road. It seems to happen when I’m going between 30 and 45 mph. It breaks so hard that if a car behind me was following, they could run into me. Whenever it breaks, I have to put my foot on the accelerator to get the car to go back forward.

46 Adaptive Cruise Control problem of the 2026 Tesla Model Y

Failure Date: 07/15/2026

On many occasions in the year we have owned our Tesla Model Y, we have experienced sudden, unexplained braking while using the traffic aware cruise control (tacc) feature. We have experienced several near-misses of cars or semi tractor trailers rear-ending us. These incidents were avoided by quick reaction of the Tesla driver to override the tacc. I have documented several incidents using the dash camera on the car and have assembled a spreadsheet of times and places of occurrence that correspond to the videos. One Tesla service representative dismissed my complaint by saying the feature is working as designed, so nothing further was done. A representative at a different dealership acknowledged that it is a known characteristic in the current firmware and they expect it to be addressed in a future software update. As I said, we have been experiencing this for over a year. It is a clear safety hazard, not only for the Tesla driver and passengers, but also for any vehicle following who has to react to the sudden, unexpected braking.

47 Adaptive Cruise Control problem of the 2021 Tesla Model Y

Failure Date: 07/13/2026

Shortly after I purchased and activated Tesla full self-driving (supervised), my vehicle's driver-assistance system stopped functioning. Autopilot and fsd became unavailable, the vehicle cameras stopped functioning properly, gps/navigation positioning stopped functioning properly, and the vehicle could no longer communicate normally with the driver assistance system (das). Service mode testing showed das ethernet communication failure. I attempted multiple troubleshooting procedures, including vehicle reboots and resets. The low-voltage battery was also replaced, but the driver-assistance failure remained. I cancelled my fsd subscription on July 13, 2026 because the purchased feature was not functioning and sought assistance from Tesla. I subsequently had a Tesla service appointment on July 16, 2026. Tesla advised that the autopilot computer would need to be replaced and quoted approximately $3,000 for the repair/replacement. The failure occurred after the fsd purchase/activation and associated software changes. I am concerned that a Tesla software update or fsd-related software may have contributed to the hw3 autopilot computer failure, but I do not know the definitive technical cause. This is a safety concern because multiple driver-assistance and camera-dependent functions became unavailable simultaneously. The vehicle is available for inspection. I am requesting that NHTSA review this failure and compare it with similar hw3/autopilot computer failures reported by other Tesla owners.

48 Adaptive Cruise Control problem of the 2023 Tesla Model Y

Failure Date: 07/12/2026

We recently got a subscription for Tesla's full self driving (fsd) system. While using the system, on several occasions, the car "jerked" momentarily. Like it is hard braking but then the car resumes its previous pace. Again, this is very quick, perhaps taking less than a second. It is an occasional occurrence, but it has happened enough times that I am not using the feature anymore. For a split second, it feels like the car was stopping abruptly, which startled everyone riding in the car. My wife called Tesla and provided the information above to an automated help center. She was told to try the "hurry" mode in fsd. We've been using the "standard" mode.

49 Adaptive Cruise Control problem of the 2026 Tesla Model Y

Failure Date: 07/12/2026

Tesla full self driving has no way to limit the speed or lane changes, and even in its standard profile it keeps going 15+ over the limit. Chill mode occasionally goes 10+, and sloth switches between -10 and +5 erratically. It's unsafe to use and there's no way to do anything about it without a manual speed limit, like it used to have.

50 Adaptive Cruise Control problem of the 2023 Tesla Model Y

Failure Date: 07/03/2026

I am submitting this report based on my personal experience operating a Tesla Model Y equipped with full self-driving (fsd). I have used fsd for approximately four years and have extensive experience with the system. During several recent road trips through heavily forested and mountainous areas, including yosemite national park and multiple locations throughout oregon, I repeatedly observed similar unexpected behavior under the same environmental conditions. On roads where dense tree cover creates alternating bands of sunlight and shadow across the pavement, the vehicle occasionally performs abrupt deceleration, unnecessary braking, or jerky speed adjustments despite there being no visible hazards, obstacles, pedestrians, or animals in the roadway. I cannot determine the technical cause, but based on repeated observations at different locations, it appears that rapidly changing lighting conditions or high-contrast tree shadows may present a perception challenge for the vision-based driving system. This is only my observation and not a technical conclusion. My concern is that unexpected braking or sudden speed changes could surprise following drivers and increase the risk of rear-end collisions, particularly on two-lane highways or winding mountain roads. While I remained attentive and was able to supervise the vehicle, these unexpected reactions occurred multiple times under similar conditions. I respectfully request that NHTSA evaluate this type of real-world driving environment as part of its ongoing assessment of advanced driver assistance and automated driving systems. Forested roads and mountain highways are common throughout the united states, and ensuring reliable performance in these challenging lighting conditions is important before wider deployment of autonomous driving technology. I would be happy to provide additional information if needed.

51 Adaptive Cruise Control problem of the 2021 Tesla Model Y

Failure Date: 07/02/2026

Safety features on vehicle stopped working after software update was pushed to my vehicle. Gps, all cameras including backup camera and ones used for blind spots, and cruise control have all stopped working. Time displays incorrectly due to gps issue and night mode stays on so rear view & back window stay dark making it hard to see other vehicles around me during the day. I’ve followed all recommended steps to resolve and issue persists.

52 Adaptive Cruise Control problem of the 2026 Tesla Model Y

Failure Date: 07/01/2026

Supervised self driving. The latest software requires drivers to divert attention from the road to enter information on the screen whenever self driving is disengaged. This is potentially dangerous.

53 Adaptive Cruise Control problem of the 2022 Tesla Model Y

Failure Date: 07/01/2026

Fsd / vision system , no warnings , the vehicle is turning left and right on a straight road sunny conditions. I have a video that it wouldn’t let me attach to the case. I had Tesla service review this and they told me it’s standard behavior, this never occurred before and is dangerous and unusable. Autopilot has an issue that Tesla themself can’t detect and when I get into an accident it’ll be too late. I’ve been complaining about this for 3 months and Tesla keeps telling me it’s standard behavior, this never happened before the car used to drive straight, brand new tires front and back , blanket and aligned the car drives straight while not in autopilot, issue is directly related to fsd and Tesla autopilot.

54 Adaptive Cruise Control problem of the 2024 Tesla Model Y

Failure Date: 06/30/2026

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.

55 Adaptive Cruise Control problem of the 2026 Tesla Model Y

Failure Date: 06/28/2026

The contact owns a 2026 Tesla Model Y. The contact stated that while driving approximately 55 mph with the cruise control engaged the vehicle lost automotive power. No warning lights were illuminated. The failure had occurred on several occasions. The vehicle was not diagnosed or repaired. The manufacturer was notified of the failure and had received similar complaints; however, there was no fix available for the failure. The failure mileage was approximately 100.

56 Adaptive Cruise Control problem of the 2024 Tesla Model Y

Failure Date: 06/26/2026

The full self-driving (fsd) system on my 2024 Tesla Model Y repeatedly causes the vehicle to weave or oscillate from side to side within its lane, particularly at highway speeds. The vehicle is available for inspection upon request. The most serious incidents have occurred at highway speeds while traveling in the left lane next to a concrete median. The vehicle has weaved so severely that it has nearly caused me to hit the concrete median. I attempted to steady the steering wheel with my hands, but this was not sufficient to stop the oscillation. I had to immediately disengage fsd to stop the behavior and regain stable control. This has happened more than once. The problem is independent of rain, wet pavement, poor weather, or unusual road conditions. I have experienced it in dry, clear weather and normal road conditions. There are no warning lamps or messages before the weaving begins. Tesla inspected the vehicle for this problem on July 22, 2026. Tesla service found no physical defect and told me the behavior was a known software/firmware problem that could not be repaired at the service-center level. Tesla personnel indicated that similar behavior was known to be occurring in europe. I was told that a future software update would correct the problem. Since then, Tesla has released multiple software/fsd updates and my vehicle has received subsequent updates. The weaving may have improved slightly on city streets and at lower speeds, but I have not observed meaningful improvement at highway speeds, where the greatest safety risk occurs. The weaving also creates a risk to surrounding traffic because the vehicle may appear to other motorists to be driven by an impaired or otherwise unsafe driver, potentially causing them to react to its unpredictable movement. Tesla has inspected and acknowledged the problem, but the high-speed safety issue remains unresolved and they do not expect any additional remedy from the dealer for my vehicle.

57 Adaptive Cruise Control problem of the 2022 Tesla Model Y

Failure Date: 06/22/2026

This week, I was driving my Tesla at approximately 65 mph in the middle lane of a six-lane freeway. Autopilot was engaged. Traffic was moving normally, and I was not aware of any obstacle or hazard that would have required emergency braking. Without any warning, the vehicle suddenly applied the brakes and rapidly decelerated until it came to a complete stop in the middle travel lane of the freeway. I was not pressing the brake pedal. The event occurred unexpectedly and created a potentially life threatening safety hazard. My vehicle came to a stop in a high-speed traffic center lane! after I disengaged autopilot and pressed the accelerator, the vehicle responded normally. Immediately following the incident, the display showed the message “autopilot unavailable. ” that message later disappeared, and no additional warning messages remained on the screen. I contacted Tesla to report the incident. Tesla reviewed the vehicle’s logs remotely and later discussed the results with me by telephone. During that conversation, I was told that the event was considered an “anomaly. ” I was also told that the vehicle logs reflected the event approximately one hour from when it actually occurred and that the logs indicated the vehicle was not operating in autopilot at the time of the incident. This information was inconsistent with the event, because autopilot was engaged when the sudden braking occurred. I could not even move to berm. Tesla did not request that I bring the vehicle in for a physical inspection. Instead, I was told there was no reason to have the vehicle examined. During the same conversation, I was encouraged to consider subscribing to Tesla’s full self-driving (supervised) system, which requires an additional monthly subscription, rather than continuing to use autopilot as a result of a question I asked about two plans. Tesla closed my service ticket without performing an inspection indicating there was no benefit spending $$ to essentially receive no additional.

58 Adaptive Cruise Control problem of the 2026 Tesla Model Y

Failure Date: 06/21/2026

We have owned a 2026 Model Y Tesla for one week and have encountered these dangerous behaviors while in full self drive mode, even in “sloth” mode: 1. Tailgating, repeatedly, while at highway speeds. Controls did not allow me to increase trailing distance while in fsd. 2. Dangerous merging, cutting off other cars. 3. Failure to read surface directions and driving wrong way against oncoming traffic. And this is with only one week of casual driving!.

59 Adaptive Cruise Control problem of the 2023 Tesla Model Y

Failure Date: 06/21/2026

My Tesla has repeatedly exhibited dangerous behavior while full self-driving (fsd) is engaged. On multiple occasions, the vehicle has stopped for a red light and then proceeded through the intersection while the traffic signal was still red. This has put my family and others at risk on a public roadway and creates a serious safety concern. One documented incident occurred on June 21, 2026, while my family was in the vehicle. During that event, the car stopped at a red traffic light and then proceeded to attempt to run intersection even though the light remained red. This was alarming and dangerous, and it required close driver supervision because the system did not behave in a safe or reliable manner. This was not an isolated incident. My Tesla has run red lights in this same manner on multiple occasions while fsd was engaged. In addition, the vehicle will suddenly stomp on its brakes on a public roadway, which is another serious and unpredictable safety issue. I have taken the vehicle to Tesla regarding these issues, and I was told that this behavior is considered normal and that nothing would be done about it. Tesla’s response was that the software is still being developed, and that this is essentially part of the risk of using the software. These repeated failures involve traffic signal compliance and erratic vehicle behavior that could easily result in a crash or injury. My family has been placed in danger by these events, and I believe this is a serious safety defect that needs to be investigated immediately. I am requesting that NHTSA investigate Tesla’s fsd system for repeatedly stopping at red lights and then proceeding through the intersection while the signal is still red, as well as for sudden unnecessary braking events on public roadways.

60 Adaptive Cruise Control problem of the 2026 Tesla Model Y

Failure Date: 06/17/2026

On the highway, a vehicle in the lane next to me on the right moved towards the white dividing line, but never actually crossed into my lane. My Tesla was operating on full self-driving (supervised). The system miscalculated the front vehicle's trajectory and severely overreacted to it approaching the line. Without driver input, the fsd system initiated sudden, heavy braking and violently swerved to the left, crossing the lane line. Because the Tesla swerved suddenly into the left lane, the driver already occupying that lane was unable to avoid a collision, striking the left rear corner of my vehicle. I have video recordings from my Tesla that provides objective proof that the vehicle in front did not sideswipe or cut off my car, but rather that an abrupt vehicle automation failure forced my car out of its lane, I had no chance to react quick enough to avoid the accident. It also provides context as to why the driver behind me could not avoid the impact. I have preserved the video files and am ready to submit them to you immediately. Best regards [xxx] information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

61 Adaptive Cruise Control problem of the 2024 Tesla Model Y

Failure Date: 06/17/2026

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.

62 Adaptive Cruise Control problem of the 2026 Tesla Model Y

Failure Date: 06/15/2026

Using Tesla fsd 14. 3. 3. It began raining hard, causing standing water to pool on the road. The standing water was making the car lose traction and started sliding within the lane, it did change its speed or driving to account for the rain. Fsd was doing over the speed limit and would not slow down slower than the speed limit. Changing the Tesla speed profile from standard to sloth slowed it down to exactly the speed limit but no lower. At this point the car could not maintain its lane, I feared for our safety, so I had to disengage fsd to regain control of the car. Tesla have removed all methods of allowing the driver to maintain accurate speed control of the car and it often ignores speed limit signs, which means it is traveling too slow or too fast for the currently posted speed limit.

63 Adaptive Cruise Control problem of the 2022 Tesla Model Y

Failure Date: 06/11/2026

Tesla y on the freeway, fsd on(full self driving), driving at 70 mph. I saw the cars ahead are slowing but my car was not slowing, so I braked and held the steering wheel firmly. However, my car still hit the car in front at 36 mph. The airbag deployed and luckily I only sprained my thumb in both hands in holding the steering wheel very hard. If I didn't take over my car would have hit the car in front at 70 mph. I downloaded Tesla "vehicle data report" and it shows that the "fsd was active, cruise control state was active, driver monitoring detection was detected and I applied the brake. I used fsd for over 3 years and no problem at all, until the accident. The Tesla data shows that the fsd malfunctioned that caused the accident but my insurance told me that it was my fault and they increased my insurance for $227 a month.

64 Adaptive Cruise Control problem of the 2024 Tesla Model Y

Failure Date: 06/08/2026

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. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(.

65 Adaptive Cruise Control problem of the 2021 Tesla Model Y

Failure Date: 06/07/2026

On June 7, 2026, my 2021 Tesla Model Y with approximately 37,131 miles became completely unresponsive and could not be driven. Tesla mobile service replaced the 12v low-voltage battery on June 11, 2026. The official repair notes stated that the battery was replaced, proper operation was verified, there were no active alerts, and the vehicle was in excellent condition. Shortly after this repair, multiple vehicle systems stopped functioning, including all cameras, navigation/gps, and software/firmware updates. Tesla service later diagnosed the vehicle as requiring replacement of the hw3 vehicle computer at a cost of approximately $3,066. The loss of camera functionality disabled or affected multiple driver assistance features that rely on the camera system. The vehicle has been unavailable for approximately one month while awaiting repair. During discussions with Tesla service regarding the diagnosis, I was informed verbally by the service manager that they see similar hw3 computer-related issues on a regular basis (approximately every other week). I cannot independently verify that statement, but I am including it because it contributed to my concern that this may not be an isolated incident. I am not asserting the root cause of the failure. I am submitting this complaint because the loss of the vehicle’s camera system and related driver assistance functionality may represent a potential safety concern, and I believe NHTSA should be aware of this incident.

66 Adaptive Cruise Control problem of the 2023 Tesla Model Y

Failure Date: 06/05/2026

I was driving down a city street near my home and put my Tesla Model Y in full self driving and looked down for 1-2 seconds to retrieve something from my center console and the warning notifications started going off and before I had any time to react, the car drove into a parked car at approximately 39 mph. I have records showing the car was in full self driving for 5 seconds before impact.

67 Adaptive Cruise Control problem of the 2024 Tesla Model Y

Failure Date: 06/03/2026

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.

68 Adaptive Cruise Control problem of the 2021 Tesla Model Y

Failure Date: 06/01/2026

* 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.

69 Adaptive Cruise Control problem of the 2024 Tesla Model Y

Failure Date: 06/01/2026

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.

70 Adaptive Cruise Control problem of the 2026 Tesla Model Y

Failure Date: 06/01/2026

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.
