Assist Problems of Tesla Model Y - part 1

On October 7, 2026 at about 5:01 pm, on I-75 near acworth, georgia, in clear daylight, my 2023 Tesla Model Y was operating with full self-driving (supervised) engaged at about 76 mph. The vehicle moved from a general traffic lane into an express lane that was closed, and continued toward physical barricades and an impact attenuator at the end of the closed lane. At least three advance signs indicated the express lanes were closed, including an overhead gantry reading express lanes closed directly ahead, and the word express was painted on the pavement under the vehicle. The vehicle did not slow, issued no warning or takeover request, and made no evasive maneuver. I avoided the barricades with a reflexive steering input. At that moment there was a concrete divider on my left, a tractor-trailer in the lane to my right, and, as I learned only from the footage afterwards, a vehicle following in the lane I moved into. There was no collision and no injury. Tesla's own vehicle data export confirms the sequence. The self-driving state was active_fsd continuously from 3:53 pm until 5:01:09 pm, when it changed to unavailable in the middle of a rising steering torque (0. 42 to 0. 92 nm, peaking at 2. 01 nm). That is consistent with a driver override, not a handover request. No automatic emergency braking event, forward collision warning or takeover alert is recorded in the surrounding two minutes. Speed was 76 mph before the intervention and 63 mph six seconds later, with no brake event. I have preserved all six dashcam cameras for the six minutes around the event, the vehicle data export, and a recording of the in-car dashcam viewer showing "70 mph, self-driving" shortly before the event. The vehicle received a software update on October 11, so I cannot confirm the fsd version active on October 7. Tesla's support interface cited fsd v14. 3. 11 and software 2026. 33. 5. When I reported this through the Tesla app, it directed me to submit a bug report and report to NHTSA.

On October 1, 2026 at approximately 7:55 pm, I was driving my 2021 Tesla Model Y with autopilot/driver-assistance engaged. The vehicle struck a fixed support pole of the canopy at my driveway. The pole was stationary, but the vehicle did not avoid it. The collision caused significant damage to the vehicle and canopy/pole. I am concerned that the Tesla driver-assistance system failed to detect and/or respond appropriately to a stationary object while engaged. I am not aware of any warning or intervention that prevented the collision. I preserved the available Teslacam/usb data and made a separate backup. I also have photographs and other documentation. I contacted Tesla and requested review of the vehicle logs, camera data, autopilot/fsd data and diagnostic/event information. As of this complaint, I have not received a substantive response explaining the incident or confirming the driver-assistance system is safe to use. This is a serious safety concern. Children, including my grandchildren, are frequently present around this driveway, and I regularly transport my grandchildren in this vehicle. I am requesting that NHTSA investigate this incident and the performance of the driver-assistance system.

I and other telsa drivers report Tesla fsd takes too long to enter a lane from which the car has to turn. Some drivers report “last minute” trying to get into turn lane or expressway off ramp. Twice last week my Tesla (model y built in June 2026) waited much too long to get into the required turn lane. On both occasions I was either in outside lane needing to turn left, or middle lane needing to turn left. One first occasion Tesla in fsd was only 0. 3 miles from the turn as cars behind stacked up preparing to make the left turn. On second occasion, car in fsd was only 0. 2 miles from turn, even indicating by led light strip turning red, that a car behind was in my blind spot. Yet, the Tesla wedged itself in front of the car behind already in the turn lane forcing that driver to slam on his brakes to let Tesla in for the turn. The second occasion could have resulted in an accident or incited a road rage incident from the driver behind. I asked grok to request Tesla engineers fix this fsd poor decision-making. Grok said he’s aware of this problem, correctly referring to it as a “lane change timing” issue, but stated he could not message Tesla engineers. At next opportunity, I sent a message via microphone in my car, though not during a “why did I take over intervention” request, because I did not intervene. Grok offered help saying I could use my turn signal to get in turn lane further in advance of the turn, or change speed mode to adjust for traffic behind, but that defeats use of fsd. Would NHTSA please make this a priority issue for Tesla engineers to fix?.

On 09/24/2026 at approximately 4:41 pm, my 2023 Tesla Model Y drifted toward the center divider. When I attempted to steer right, away from the divider, the steering felt locked and unresponsive, and the vehicle struck the divider at approximately 24 mph. Airbags did not deploy; no injuries. Vehicle data obtained from Tesla shows: cruise control was engaged approximately 7 seconds before impact and disengaged approximately 2 seconds before impact; about 1. 5 seconds before my rightward steering correction, the steering wheel swung hard left (~24°) without driver input; I then applied rightward steering effort and the wheel turned right (up to ~91°) while I was braking; the vehicle displayed "take control immediately — vehicle departing lane" at the moment of the event; after impact it reported "automatic emergency braking is unavailable" and "autopilot cameras unavailable. " damage was repaired at a cost of $11,467. 75. I am reporting this because the steering behavior — the unexplained leftward swing and the unresponsive steering when I attempted to steer away — suggests a possible defect in the steering or lane-keeping system that could affect other vehicles.

Critical fsd lane change - 2020 Tesla Model Y software 2026. 26. 6. 5 and fsd v14. 1 lite changed lanes suddenly and violently at freeway speed while entering an express lane with flexible lane delineators between the express lanes and the freeway. The automation made the lane change at the very last second, narrowly avoiding impact with the plastic posts, and swerving back into the left-most freeway lane. The action of the fsd could have caused a loss of control of the vehicle as it compensated for the weight shift caused by suddenly swerving. There was space between the Tesla and other vehicles at the time but this could have been catastrophic with only slight changes to the road condition etc. . . Reported to Tesla fsd beta team. No known failures, warning lights or other issues with the car.

I run fsd 96% of the time. It’s so good that I get somewhat complacent. That’s not a character flaw. That’s what a reliable system does to people. The failure mode is simple. Car is holding a curve. Foot accidently brushes the brake. Autosteer disengages. Assist steering torque goes to zero. Wheel unloads. At speed the path goes straight, worst cases, into barrier, pole, or oncoming lane. A heavy Tesla in that geometry is ugly. Tesla’s answer is always the same: the driver disengaged, so it’s not on us. The accident is losing lateral control because of another control (braking) that should only change speed. Brake pedal grazes are easy and inevitable. I can recover a braking event. But I may not recover an instant straight-line on a bend if my hands weren’t on the wheel. Simple fix: disengage traction but don’t have fsd disengage autosteer until I force the wheel. That way fsd knows I have control instead of only assuming that. I love fsd but always feel there is a suicide/killer stick just inches away from my feet. To answer your question, there is no component failure and safety risk is obvious. I can reproduce the scenario by simply tapping the brake on a curve and feel the wheel try to jerk out of my hands. Tesla acknowledges that this is the way the system was designed: complete instant manual takeover. The normal fsd disengagement tone rings. But that is too little, too late for a surprised driver.

Lane departure pulls the car unsafely when two lanes merge or one lane splits. It has caused us to swerve a few times leading to major safety concerns. It's locked by software we are forced to turn off manually every time we drive. Even when off it seems to pull me around on certain roads.

This is an issue with Tesla's full self driving (supervised). The categories above don't match this capability. Sunday, xxx, about 6:05 pm. Fsd (supervised) version 14. 3. 9. Leaving in-n-out burger, [xxx], fsd chose to exit westbound onto [xxx]. A vehicle coming from the east had gone around the queue on my right and was westbound on [xxx]. Fsd pulled forward so the nose entered that westbound lane in front of that car. I intervened with throttle and steering. No contact. Since I didn't honk there was no saved dashcam clip.

On September 11, 2026 at 5:11:51 pm in san jose, CA, fsd (supervised) had been engaged continuously for 23 minutes. The vehicle was traveling straight in its lane at 32 mph and still accelerating. Fsd disengaged with no takeover warning: no visual alert, no chime. My data export from the manufacturer (200 ms resolution) confirms the timestamp and shows the driver-monitoring channel never entered either of its warning states during the drive, though both appear elsewhere in my data. Nothing I did caused it. Steering torque stayed within sensor noise, with no rightward torque at any point. First brake application was 5. 56 seconds after; first accelerator input 15. 5 seconds after; no steering wheel button events near the event. Immediately afterward the steering angle moved about 7 degrees right over five seconds with my torque still near zero. The vehicle left its lane toward parked cars and came very close to striking them. No forward collision warning, no automatic emergency braking. I braked manually and stopped. I re-engaged fsd 36 seconds later and again two minutes later. Both times it steered right again and I disengaged. No warning lamps or messages appeared before any of this. The manufacturer reviewed logs remotely but has not inspected the vehicle or reproduced the problem. They attribute it to reduced forward camera visibility. My export shows one camera-related alert for that drive, logged 23 minutes earlier and absent from the incident window. They later stated the vehicle logged 30 non-customer-facing "low" obstruction events over two weeks, and that a customer alert appears only for significant obstruction. I drove extensively in that period without incident. A condition judged not worth notifying me about should not also explain withdrawal of steering control at 32 mph. Root cause is unconfirmed pending a paid diagnosis I have not authorized. Vehicle available for inspection. I have dashcam footage and the full export.

2023 Tesla Model Y – hw3 autopilot computer/camera system failure my 2023 Tesla Model Y has approximately 54,000 miles and is equipped with the Tesla hardware 3 (hw3) autopilot computer. After receiving Tesla's fsd v14 lite software, the vehicle began intermittently losing camera-based driver-assistance functionality. I observed an app_w141 ecu thermal issue alert. The vehicle subsequently experienced aps_w134_appmia and aps_w135_appcritical alerts indicating that the autopilot processor secondary was losing communication with and detecting a malfunction of the autopilot processor primary. When the problem occurs, camera/vision functions and driving visualization become unavailable or degraded, and the vehicle has reported self-driving features limited, cruise control unavailable, adaptive headlight features unavailable, and other driver-assistance limitations. In Tesla service mode I have documented the primary autopilot processor repeatedly changing between init, critical and coreboot while the secondary processor remains nominal. A das reset can temporarily restore communication, but the failure returns. Tesla has proposed replacing the entire hw3 car computer at a cost of approximately $3,120. I am concerned that this may represent a safety-related hw3 computer failure, particularly because I observed an ecu thermal alert and because the failure removes multiple camera-based driver-assistance and safety functions. I have photographs documenting the alerts and processor states and have an open Tesla service case.

I had the car in full self driving mode. The car turned off the road into a ditch, in which I had to take over the car.

I recently purchased this vehicle. I love it. It has a trial of full self driving, which I love almost all of the time. However, I noticed there is not any of the 5 settings for fsd that do not speed in school zones. I want to use fsd as much as possible, but I will not speed in a school zone. I am amazed that Tesla has been allowed to program the fsd in a way that will allow speeding in a school zone. I have to turn off fsd to maintain safety and avoid a ticket. Please require Tesla to have at least one of the 5 settings that will obey school zone speed limits.

On August 26, 2026, the vehicle’s full self-driving system was involved in three separate incidents. Between approximately 1:00 pm and 3:00 pm, while exiting a parking lot onto a main major street with full self-driving engaged, the vehicle struck the curb. At approximately 6:20 pm, while driving approximately 40 mph on a local road, one street before turning onto the highway, the vehicle began drifting out of its lane without warning for no apparent reason — it is unknown whether this was an attempted automated lane change or a system error. There was oncoming traffic in the adjacent lane at the time; I immediately took manual control of the steering wheel and applied the brakes to correct the vehicle’s path and avoid a collision. At approximately 6:45 pm, while exiting a different parking lot onto a main major street with full self-driving engaged, the vehicle struck the curb a second time. No warning lamp, alert, or message preceded any of these events, and no collision with another vehicle occurred in any of the three incidents. The vehicle has since been returned to the dealer where it was purchased. I am uncertain whether the dealer has separately reported these incidents.

Subject: safety hazard caused by emergency lane departure avoidance on [2026 Tesla Model Y] description: I am writing to report a serious safety issue regarding the emergency lane departure avoidance (elda) feature on my us-spec Tesla. Starting with recent software updates, the vehicle forces the lane departure avoidance setting back to "assist" upon every single drive cycle, with no option to disable it permanently. This behavior creates an immediate safety hazard, especially in cold climate regions and during winter driving conditions. When attempting to steer around immediate road hazards such as open manholes, deep potholes, or debris, the vehicle's cameras fail to recognize the object in the road. If the driver maneuvers to avoid the hazard without a pre-activated turn signal, the elda system aggressively intervenes, jerking the steering wheel back into the path of the danger. On slippery, icy, or wet roads, this unexpected electronic intervention causes a sudden loss of traction, risking a severe crash. Forcing a driver to navigate multiple sub-menus on a touchscreen to change a safety-critical setting before every single drive is dangerous and distracting. In the united states, there is no federal mandate requiring this setting to reset to "assist" on every drive. I request that NHTSA investigate this aggressive software behavior and compel Tesla to restore the option for owners to permanently set lane departure avoidance to "warning" or "off".

On 8/22/2026, my 2022 Tesla Model Y long range with approximately 81,000 miles developed an electronic power assisted steering (epas) fault immediately after I felt a brief jerk while reversing. The vehicle displayed “steering assist reduced / steering may require increased effort. ” manual steering currently feels normal, but full self-driving/autosteer and lane departure/lane keeping functions became unavailable. Tesla service mode shows repeated faults epas3p_a072_motfeedfwderror, epas3p_a049_pictrlerror, and ui_a020_steeringreduced. For epas3p_a072, Tesla’s diagnostic screen describes a “motor control feed-forward correlation error,” lists the potential impact as “reduced steering assist and eac inhibited,” and specifically lists “replace epas” as the clear condition. The faults return after vehicle power-off and reboot. The vehicle was updated to software 2026. 21. 6 / fsd v14 lite approximately two weeks before this occurred. There were no previous steering warnings. I am not claiming the update caused the failure, but I believe the timing warrants investigation. Nhtsa complaint 11749826 describes a 2021 Model Y with the same epas3p_a072 and ui_a020 faults, including Tesla service mode stating “replace epas. ” complaint 11758026 describes another 2021 Model Y steering gear failure and requests expansion of recall 25v-092 to earlier Model Ys. My vehicle has not yet been physically inspected by Tesla. The vehicle and diagnostic information are available for inspection. I request NHTSA investigate whether this epas failure extends beyond the current recall population and whether recent software changes may be contributing.

On July 30, 2026, at approximately 8:10 pm cdt, my 2025 Tesla Model Y was operating with full self-driving engaged when the vehicle descended a private boat launch at a marina in antioch, IL, and entered the river channel connecting channel lake and lake marie. Two occupants escaped through the windows. The vehicle was submerged and is a total loss. Lake county sheriff report #26-104915. The vehicle's incident data export confirms fsd was in an active state during the approach. The vehicle is preserved in storage pending inspection. An incident report has been filed with Tesla.

On the day after taking delivery of my 2026 Tesla Model Y, fsd reversed into a visible stationary garage pillar while backing into my garage. The vehicle did not stop before impact and stopped only after contacting the pillar, resulting in more than $6,000 in vehicle damage. The following day, while fsd was attempting a left turn at an intersection, the vehicle nearly entered the opposing-traffic lane before making several hesitant steering corrections. I disengaged fsd and completed the turn manually to avoid a potential collision. Both incidents occurred within two days of delivery. Tesla has opened a service case, escalated the matter to its engineering team for review, and I have requested preservation of all available vehicle data. I am submitting this complaint because these incidents raise concerns about the safety of fsd behavior.

Full auto pilot I pay $99 every month and it was on the car decided to take a turn to go over the middle island and hit the tree. The road has yellow line straight but then the yellow line start to be. . . I think the car decided OH my god it’s not the correct way and decided to take off and run over the middle island and hit the tree. Totaled the whole car and then the fire or the smokes are to go inside car what I was stuck inside I tried to open the door, but then five minutes later I got out almost died.

On 7/22/2026 between 6pm and 7pm pst, I was driving my Tesla Model Y on I-405 southbound in orange county, CA, between the westminster blvd exit and exit 73, with full self-driving (supervised) engaged. The incident occurred at an express lane ingress/egress transition zone where a physical barrier separates the express and general-purpose lanes. While in fsd mode, the vehicle initiated a lane change on its own. During the lane change, the fsd system misjudged the lane boundary and steered the vehicle into the lane divider/barrier. The vehicle struck the divider on the front right side. The failed system is the fsd/automated steering and lane change function. No forward collision warning sounded and no automatic emergency braking activated before impact with the fixed barrier. There were no warning lamps, alerts, or symptoms prior to the failure; the system initiated and executed the lane change without indicating any problem. The impact damaged the front right body panel, front right bumper area, and the right headlight. My safety and the safety of vehicles in adjacent lanes was put at risk, as the collision occurred at roadway speed during an automated maneuver I did not initiate. Had the divider been a vehicle or a pedestrian work zone, the outcome could have been far more severe. All fsd telemetry, camera footage, and vehicle data from the incident should be available from the manufacturer, and I have requested the vehicle data report from Tesla. The vehicle is available for inspection upon request and is being taken to a Tesla-certified collision center for repair. An insurance claim is being filed with my carrier. The vehicle has not yet been inspected by the manufacturer or police.

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.

In my 2026 Model Y I have to turn off lane departure assistance every time I want to drive the car. In my experience, this function has been dangerous. When I am passing a semi truck, I want to DE- center myself away from the truck. Lane departure assistance forces my car towards the semi truck. It is terrifying. I’m not leaving the lane, I’m just trying to be at a safer distance as I’m passing the semi truck, and the car won’t let me when I have lane departure assistance on. I’ve been told that for the 2026 Model Y, we are forced to turn it off before every drive whereas in other models, you could turn it off and it would remain off. Since when are we forced to have our car drive for us? I thought this was a choice, but apparently I am wrong.

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.

Subject: urgent safety defect: post-disengagement touchscreen prompt causes acute driver distraction feature involved: full self-driving (supervised) post-takeover feedback modal safety concern: when a driver manually disengages fsd (supervised), it is almost always because the vehicle entered a complex, unexpected, or hazardous scenario that demanded immediate human intervention. At the exact second the driver assumes physical control of the vehicle—when 100% of driver visual attention and cognitive bandwidth must be on the roadway—the center display flashes a persistent multi-choice survey requesting feedback on why the disengagement occurred. The hazard: visual diversion during critical moments: presenting bright, interactive ui cards requiring glance time and manual touch interaction immediately after a takeover directly contradicts basic human-factors engineering and crash avoidance principles. Cognitive overload: instead of stabilizing the vehicle in manual control, the driver's attention is competed for by an on-screen prompt asking for data categorization. Ui contradiction: while the cabin camera actively penalizes drivers for split-second glances away from the road, the vehicle os simultaneously prompts the driver to look at and touch the center screen during the most dangerous phase of a driving sequence. Requested remediation: provide a toggle under controls > autopilot to disable post-disengagement prompts entirely (e. G. , "prompt for takeover feedback: off"), or suppress all on-screen interactive surveys until the vehicle is placed in park. Driver telemetry collection should never compromise active collision avoidance. --- this issues happens whenever disengaging fsd. Its not a one time thing. They have updated the software in my car multiple times but haven't fixed this. My location doesn't matter, speed doesn't matter. They added it in an update after more that two years of using the car and I cannot get rid of it.

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.

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.

While in full self driving mode in my Tesla, it was making a right turn into a parking lot when it suddenly violently accelerated. Before I could gain control it crossed the parking lot entrance, climbed the curb, and came to rest on a lawn in front of a business. Luckily no one was hurt. It appears the car will be totaled by the insurance company at the completion of their investigation.

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.

While driving in fsd the car is ping ponging between the lane. It didn't used to do this but now does it on any road. Highway, city, turns, etc. The oscillation causes me and my passengers to be sick and it looks like a drunk driver on the road.

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 June 7, 2026, I was driving westbound on I-290 in the leftmost lane in a 2024 Tesla Model Y. I recall fsd (supervised) was engaged and making a lane change into the left lane. Instead of settling in the lane, the vehicle continued left and struck the divider/median. I braked. The vehicle then bounced back and moved right toward a large truck and collided. I did not receive a takeover warning before the event. The front bumper came off and the vehicle became inoperable. A fire truck traveling behind me blocked traffic after the crash. Tesla event data records a crash algorithm wake-up at about 9:49 a. M. Central and includes speed, steering, braking, acceleration, abs, lane-assist, and cruise-control signals. I reported the safety concern to Tesla and asked for review of the fsd/software issue and data, but I have not received written findings. I do not have an expert determination that fsd caused the crash. I am asking NHTSA to review the incident and data for a possible driver-assistance, steering, or lane-control safety defect.

While operating a 2026 Tesla Model Y on full self-driving (fsd) supervised, the vehicle's vision-based lane-keeping system failed on an unmarked residential road. At approximately 26 mph, the vehicle approached a blind crest of a hill. Due to the lack of painted center lines, the fsd software miscalculated the road geometry and drifted significantly into the center/oncoming lane exactly as it reached the top of the hill. This lane departure created an immediate, severe safety hazard, as it placed the vehicle directly in the path of potential oncoming traffic with zero forward visibility over the crest. Due to the critical lane positioning error, immediate driver intervention was required. The driver took manual control of the steering wheel to force the vehicle back into the correct lane, causing the fsd system to instantly disengage. Simultaneously, the driver applied manual braking to reduce speed drastically down to 10 mph to safely clear a resident working on the right shoulder and stabilize the vehicle. Prior to the failure, there were no warning lamps, error messages, or symptoms indicating the system would fail to maintain proper lane positioning. The system appeared to be functioning normally up until the crest of the hill. The vehicle and its autopilot/fsd components have not yet been inspected by Tesla, police, or an independent service center following this specific event. The vehicle remains available for inspection upon request.

The full self-driving (supervised) software on my 2026 Tesla Model Y repeatedly performs unsafe driving maneuvers requiring manual takeover to avoid collisions. Documented incidents with timestamps since June 3, 2026 include: selecting the incorrect lane and then attempting a route correction against a red light; activating the left turn signal while executing a right turn; attempting to enter a freeway from an incorrect lane; repeatedly missing exits, on-ramps, and turns; and making unnecessary lane changes. In one drive on June 9, the system missed two exits, a freeway on-ramp, a left turn, a right turn, and a u-turn twice within 18 minutes. On July 8, 2026, hours after the vehicle was returned from service with the manufacturer's advised mitigation active, the system repeated the same errors and drove the wheel into a curb, causing wheel damage. My safety and that of other road users was put at risk by incorrect lane positioning, incorrect signaling, and a red light conflict. The manufacturer's service center has inspected the vehicle twice (completed July 8 and July 21, 2026). Both visits were closed with no repair performed. The only action was advising me to disable the online routing setting as a temporary workaround, which did not prevent recurrence. The manufacturer stated in writing on July 8 that this is a known software-related matter its engineering teams are actively working to resolve, and a service advisor described it verbally as a firmware issue. However, the manufacturer's written response on July 31 states diagnostics identified no faults. A service center supervisor verbally acknowledged experiencing similar behavior on his own vehicle, indicating the defect is not unique to my vehicle. Service records, complete timestamped incident logs, and dashcam footage of the incidents are preserved and available for inspection upon request. No warning lamps or fault messages appeared before or during any incident.

I am reporting a safety incident involving my 2025 Tesla Model Y and full self-driving. While driving with full self-driving engaged… latest update, the vehicle steered into an express-lane barrier/bar structure. The impact caused severe windshield damage and apparent body damage near the passenger-side a-pillar / windshield frame / roof rail area. The windshield is heavily cracked across the driver’s side and center area, and the vehicle is not safe to drive. I was able to get home safely and filed an insurance claim. I preserved Teslacam footage and photos of the damage. The in-vehicle Tesla playback shows full self-driving engaged during the incident. I also copied the Teslacam files from the vehicle’s usb drive. The exported video file does not appear to show the same full self-driving overlay that appears in the in-vehicle playback. I am reporting this as a potential safety issue involving Tesla full self-driving steering behavior and impact with a fixed roadway/express-lane structure. No injuries occurred, but the vehicle sustained significant windshield damage and possible body/frame-area damage.

* 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.

Incident report – 2026 Tesla Model Y date of incident:xxx time of incident: 12:30 am location: [xxx] I was operating my 2026 Tesla Model Y and was driving manually. Full self-driving (fsd), autosteer, and other self-driving functions were not engaged at the time of the incident. While traveling on highway 16 at approximately 60 mph, the vehicle approached the right-side white lane line. At that point, I experienced a sudden steering intervention that turned the vehicle sharply to the left. The steering input was unexpected and occurred while I was manually controlling the vehicle. Following the steering intervention, the vehicle crossed the centerline into the opposing lane of travel and continued off the roadway into the ditch on the opposite side of the road. The incident resulted in damage to the vehicle. Road conditions were dry. Weather conditions were safe. Lane markings were clear. I am requesting that Tesla preserve and review all vehicle telemetry, event logs, steering-assistance records, and any other relevant data associated with this incident. Specifically, I request an investigation into whether lane departure avoidance, emergency lane departure avoidance, or any other driver-assistance feature activated and contributed to the steering maneuver. I am also requesting a determination regarding responsibility for the resulting vehicle damage and whether Tesla will reimburse repair costs if a system malfunction or defect is identified. Supporting documentation, including photographs, dashcam footage (if available), repair estimates, and other evidence, can be provided upon request. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).
