Automatic Emergency Braking Problems of Tesla Model Y - part 1

On 10/08/2026, while full self-driving (supervised) software v14. 3. 10 was engaged in an underground parking garage, the vehicle failed to stop when it should have, causing the left-front bumper to scrape against a concrete pillar. The driver was supervising at the time. No injuries; cosmetic damage to the left-front bumper only.

On October 8, 2026, at approximately 3:52 pm, I was reversing my 2026 Tesla Model Y (VIN 7saygded6tf606672) in the parking lot of the Tesla store/service center in north hollywood, CA, while full self-driving (supervised) was engaged. The vehicle failed to detect a stationary iron pole in the parking space and continued reversing into it, resulting in a collision that scuffed the paint and left a small dent on the rear lower bumper trim. The fsd system gave no warning and did not brake before impact. I have dashcam footage confirming fsd was active at the time of the collision. When I reported the incident to Tesla service staff at the location, they stated the collision was the driver's fault and denied any responsibility of the fsd system. I am concerned that fsd's failure to detect a large stationary metal obstacle at low speed indicates a safety defect in the driver-assistance system.

On October 7, 2026, at approximately 1:18 pm pacific time in los angeles county, California, my Tesla Model Y collided with a stationary metal post/barrier while operating under full self-driving (supervised). Fsd was controlling the vehicle during a low-speed maneuver. The vehicle moved forward and struck the stationary obstacle. I did not intentionally press the accelerator, apply the brakes, or override the steering before impact. I applied the brakes only after the collision. This was not a collision caused by my manually steering or accelerating the vehicle into the obstacle. I have preserved the original Tesla-recorded accident video, which displays the blue "self-driving" indicator during the relevant maneuver. Tesla's official vehicle data also records: 13:17:50. 255 - active_fsd 13:18:17. 661 - significant acceleration anomaly, approximately -7. 29 m/s², consistent with a possible impact 13:18:18. 268 - driver_applying_brakes 13:18:18. 285 - fsd state unavailable the suspected impact event occurred approximately 0. 607 seconds before the recorded manual braking event. This supports my account that I braked in response to the collision, not before it. I am concerned that fsd failed to avoid a stationary obstacle while controlling the vehicle. I request that NHTSA investigate fsd obstacle detection, path planning, steering, propulsion and braking behavior, and whether adequate collision warnings were provided. I request preservation and examination of Tesla's complete fsd logs and an assessment of whether the automated system contributed to this collision. I dispute any assumption that this incident was caused solely by manual driver operation. I have the original video, Tesla csv data and damage photographs available as evidence.

On October 7, 2026, at approximately 1:00 pm, I was driving through a gated entrance. Full self-driving (supervised) was engaged when the vehicle made contact with the entrance gate arm/barrier, resulting in property damage. The apparent safety issue was that, while fsd (supervised) was controlling the vehicle’s movement, the system did not prevent the vehicle from contacting the barrier. Afterward, the vehicle did not display or save the collision as a detected safety event. No one was injured. The incident nevertheless created a safety risk because the vehicle contacted a fixed barrier while the driver-assistance system was engaged. The issue has not yet been inspected or confirmed by Tesla or an independent service center. The vehicle is available for inspection upon request. I request that Tesla preserve and review any available data from the relevant time period, including fsd engagement status, vehicle speed, steering, braking and acceleration inputs, camera data, diagnostic logs, event data, and software-version information.

On October 2, 2026, at about 10:25 pm, I was driving my 2025 Tesla Model Y with full self-driving (supervised) engaged. I was on pineville-matthews road (nc-51) in matthews, nc, heading toward mint hill, at about 35. 12294, -80. 72472. There were no vehicles, pedestrians or obstacles ahead of me. With no apparent reason and no warning or alert, the vehicle suddenly braked as hard as possible. It slowed from about 49 mph to 32 mph within roughly one second, which averages about 0. 8 g. I took over from fsd and submitted feedback to Tesla marking the event as critical. It was nighttime and the weather was clear. Fortunately no vehicle was behind me, but if one had been, a rear-end collision would have been likely. The car was running software 2026. 27. 11 with fsd (supervised) v14. 3. 10. I have dashcam footage of the event.

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.

The vehicle made contact with other vehicles twice within a short period while full self-driving (supervised) was engaged, and it did not respond to my attempts to intervene. On xxx, at approximately 1:30 pm, in the stanford oval parking area in [xxx], I was using Tesla full self-driving (supervised) in my brand-new 2026 Tesla Model Y when the vehicle began a reversing maneuver between two parked vehicles. During the maneuver, the on-screen visualization continued to show space between my vehicle and the surrounding vehicles. The vehicle then made physical contact with another vehicle. I received no proximity or collision alert, and the display continued to show clearance after contact occurred. After contact, the vehicle continued attempting to reverse, stalled, and behaved erratically. I attempted to brake and disengage the system, but the vehicle kept glitching and moving backward. I could feel resistance while trying to control the vehicle. Shortly afterward, at [xxx], the vehicle showed substantially similar behavior and again made contact with another vehicle. My vehicle sustained damage to the rear bumper and lights. The other vehicle had pre-existing damage, and its driver told me she did not want to pursue anything or have her vehicle repaired. The vehicle is brand new and I had no prior accidents. I will be assessing myself for injuries. I reported the incident to Tesla. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

Repeated unexpected braking / suspected aeb activation my 2026 Tesla Model Y has repeatedly experienced sudden unexpected braking at the same location near my home over the past several weeks. The incidents have occurred both while full self-driving (supervised) was engaged and, importantly, while I was manually driving with fsd disengaged. During some periods, this occurs almost every morning. It has also occurred during both daytime and nighttime driving. The location currently has construction activity, and the behavior is highly location-specific. In the most serious recent incident, the vehicle suddenly braked while another vehicle was following behind us, creating a near rear-end collision. Our approximately two-year-old child was in the rear seat, and repeated sudden braking events have frightened our child on multiple occasions. We now do not feel safe driving this vehicle with our child through this location, but the road is a necessary route for entering and leaving our neighborhood. We reported the issue to Tesla and provided multiple specific timestamps. Tesla performed remote diagnostics and stated that no vehicle hardware fault was detected. Tesla told us that it believes the behavior is related to the construction/road environment at this location and that it currently has no repair or solution for the issue. My concern is that an active safety/braking system can repeatedly initiate unexpected braking during normal manual driving because of a specific road environment. The absence of a hardware fault does not resolve the safety risk. I am requesting that NHTSA document and evaluate this recurring unexpected braking behavior, including whether similar incidents are occurring in other Tesla Model Y vehicles.

On xxx, I was involved in a collision in [xxx], while manually driving my 2022 Tesla Model Y (VIN: [xxx]). Neither full self-driving (fsd) nor autopilot was engaged. I was making a right turn at a red traffic signal while another vehicle was making a u-turn. My Tesla collided with the passenger-side door of the other vehicle. Before the collision, I did not receive any audible or visual forward collision warning (fcw). I also did not observe the automatic emergency braking (aeb) system activating or attempting to slow the vehicle before impact. My approximate speed at the time of the collision is unknown. No injuries occurred. I am concerned that the vehicle's forward collision warning and automatic emergency braking systems did not respond to the collision risk. I understand these systems have operating limitations, particularly during turning maneuvers, but I would like this incident documented as a potential vehicle safety concern. I request that NHTSA review this incident to determine whether further investigation is warranted, including whether the vehicle detected the collision risk and whether the safety systems were functioning as designed.

While driving on the highway with full self-driving (supervised) engaged, the vehicle approached an exit that had been closed with traffic cones and road-closure signage. The vehicle failed to properly respond to the closure, continued through and struck multiple traffic cones, and ultimately collided with the road-closure equipment, causing significant front-end damage. My primary safety concern is that multiple safety systems appeared to provide no effective intervention. I observed no forward collision warning, no automatic emergency braking, and no effective automatic braking or avoidance maneuver, even after the vehicle had already begun striking traffic cones. There were no warning messages or indications of a system malfunction before the collision. This was a serious safety incident involving fsd, forward collision warning, automatic emergency braking, and the vehicle's obstacle-detection/collision-avoidance systems. I am requesting that Tesla immediately preserve and review all available vehicle data, including fsd status, camera/perception data, detected objects, vehicle speed, steering, braking commands, forward collision warning events, automatic emergency braking activity, and driver inputs before and during the collision. The vehicle is available for inspection. I also have evidence of the damage and incident available upon request. I am requesting a formal investigation to determine why the vehicle continued through multiple physical traffic-control obstacles without an observed collision warning or effective automatic braking intervention.

My 2024 Tesla Model Y (VIN [xxx]) has lost all forward camera-based safety and driver assistance functions. The vehicle displays alerts that automatic emergency braking is unavailable, park assist is unavailable, adaptive headlight features are unavailable, and that self-driving is degrading and the vehicle may stop. Autopilot and full self-driving will not engage. The side repeater cameras and the rearview camera still display images normally on the touchscreen, so the failure is not a loss of video display. The loss of automatic emergency braking and forward collision warning means the vehicle has no automated protection against a frontal collision, and the loss of adaptive headlights and auto high beam means the high beams no longer dim for oncoming traffic. I performed a touchscreen reboot and a full power-off reset, and the condition returned. The vehicle is equipped with hw4 hardware and falls within the Model Years covered by NHTSA campaign 25v002000 (Tesla sb-25-00-001) concerning a computer circuit board short, though my VIN was not included in that recall population. I am reporting this because a vehicle sold with these active safety systems is now operating without them, and I believe other owners of vehicles in this build range may be experiencing the same failure.

Component: the car computer (Tesla hw3 / "full self-driving computer 3," which houses the autopilot computer and gps) failed during a scheduled overnight over-the-air software update from version xxx in early xxx. The update failed to install, and from that point all cameras were black including the backup camera, navigation was frozen, and every driver-assistance feature was unavailable: autopilot, fsd, automatic emergency braking, forward collision warning, lane keeping, and blind spot monitoring. The failed unit was returned to the owner and is available for inspection. Safety risk: the vehicle remained drivable with crash-avoidance systems and the federally required backup camera disabled. The only indication was a camera-unavailable message; there was no clear warning that aeb and collision warning were off. The vehicle was driven about three weeks in this condition while awaiting parts. Confirmed by manufacturer: yes. Tesla remote diagnosis determined the car computer required replacement. Tesla remotely cancelled and re-pushed the update on xxx; the download stalled at 0 b/s and never installed. Tesla service in [xxx] replaced the car computer on xxx at owner expense ($2,489. 48; outside basic warranty, goodwill declined). Tesla's repair notes state the loss of all camera images and autopilot capability occurred "after a failed software update. " prior warnings: none. No warning lamps or messages before the update; the vehicle operated normally on xxx owner resets, power-off, and 12v disconnect did not restore function. Assessment: the autopilot computer failed during a manufacturer-pushed software update. Owner forums and automotive press reported numerous similar hw3 computer failures in summer 2026 following Tesla software releases. No crash, fire, or injury.

On 8/29/2026 my 2026 Model Y was on fsd (supervised) v14. 3. 8 (software 2026. 26. 6. 5). Daylight, clear weather, dry road. My eyes were on the road and I received no attention alerts. While in an open lane, fsd signaled and abruptly changed lanes into a closed express lane entrance blocked by lowered gate arms with reflectors and a flag. The lane change and impact happened too fast to react. There was no collision warning or alert and no braking. It hit the first arm without slowing. The arm shattered the windshield, sending glass into the cabin, then went over the hood. The car never registered the impact. With no alert or braking, it kept going at the same speed toward the remaining arms until I took over and steered away, with no visibility through the windshield. Sunglasses and a face covering are the only reason glass did not reach my eyes. I had minor skin irritation on one arm. The responding officer said he knew what happened on sight. He said Teslas on fsd crash through the arms at this exact location regularly when the express lanes are closed because they do not recognize them, and that he often writes these crash reports there. The collision repair technician said he has seen a large increase in Teslas crashing through barrier arms since July 2026 and believes a software update caused a regression in barrier arm recognition. I believe avoid tolls/hov was enabled at the time, though I am not 100% certain. It is enabled now, and fsd still routes my car into the express lanes on my commute, so the system does not appear to honor that setting. Not yet confirmed by a service center. Seen by police, an insurance adjuster and a repair shop. Vehicle available for inspection. I have asked Tesla to preserve all logs, telemetry and edr data. No dashcam footage, as the usb had failed.

I had brought my Tesla Model Y to a stop. Given that the car has an auto-park feature, I did not put the car in park. My daughter got out of the car and opened the rear passenger door. I moved towards the Tesla screen to open the rear trunk for her. As I moved, my foot accidentally hit the accelerator running the car over her foot and causing a possible fracture. She was in agonizing pain and I had to call emergency services. This situation can be easily avoided by Tesla by immobilizing the car (placing it in park) when the car has been brought to a stop or has been brought to a very low speed and any door is opened. Right now, immobilizing the car happens only if the driver door is opened when the car has been brought to a stop or the speed is very low.

On August 15, 2026, at approximately 5:00 pm, the vehicle was being driven with full self-driving (supervised) engaged during light rain. As the vehicle approached traffic ahead, it did not slow or brake as expected. The driver recognized that the vehicle was not slowing and attempted to intervene manually by pressing the brake pedal multiple times. The driver reports that despite these attempts, the vehicle did not slow or respond to the brake pedal as expected, and a collision occurred. There were no known warning lamps or warning messages indicating a braking-system problem prior to the incident. The vehicle has not yet been inspected to determine the cause of the reported braking behavior. The incident has been reported to the manufacturer, and a request has been made to preserve and review available vehicle data surrounding the collision, including braking inputs, vehicle speed, full self-driving status/actions, warnings, diagnostic information, and safety/event data. The vehicle is available for inspection. At this time, the cause of the failure to slow as expected is unknown.

While pulling into my driveway at 3–4 mph and only a few feet away from the garage door, I suffered a sudden medical emergency and became unconscious. As my body froze, my right foot accidentally floored the accelerator pedal. The vehicle did not override my foot input despite the immediate obstacle ahead. It accelerated through the garage door and the dining room wall, coming to a stop in the kitchen. As a result of this crash, I requiring a three-day hospitalization. I am filing this report because vehicle safety systems should have a setting or protocol to prevent low-speed pedal misapplications from completely overriding automatic emergency obstacle braking. These settings save lives and there are no reasons that Tesla doesn't implement it. I had problems uploading photos. Please contact me at [xxx] to provide photos. Thank you.

On Wednesday, August 12 around 6:30 am the vehicle applied aeb while I was making a left turn on green. It landed me in the middle of the intersection while a car going straight from the opposite direction was speeding towards me to go before the light turned yellow/red. I escaped a collision only because the other driver managed to slow down.

Car is less than a year old and forward camera is reporting visibility problem. Safety features, forward collision and autonomous driving is severely degraded. Tesla will not repair under warranty which requires disassembly of the camera housing. Front camera housing has been redesigned by Tesla but they are not retrofitting this fix for existing Model Y and have not issues a safety recall. This camera housing defect presents a risk to my safely and the safety of others.

While returning the Tesla during a demo drive, the car suddenly braked extremely hard in the middle of the road for no reason. It was bright and sunny, and we were coming up to a green light. It caused me to slam my head back into the seat. There was seemingly no reason for the emergency braking, and if someone were behind me, it would have caused a collision.

The autopilot/fsd computer (driver-assistance ecu) on my 2021 Model Y (hw3) began failing intermittently on August 2, 2026, days after installing a software update -fsd v14 "lite" branch. The component is in the vehicle and available for inspection. While driving at highway speed in high ambient temperatures (112–125°f), the system repeatedly disengaged with "cruise control unavailable" (alert di_a175) and "system error — take over immediately" warnings, and later alert app_w46u on fsd engagement. Failures included: fsd and autosteer aborting within seconds of engagement or disappearing from the menu entirely; complete loss of driving visualizations (no lane lines or vehicle overlays); rear camera blacking out; loss of speed-limit recognition and automatic turn-signal cancel. Both fsd and autosteer beta failed identically, indicating the fault is in the shared autopilot computer/camera pipeline, not one feature. Because the same camera/compute stack supports automatic emergency braking, forward-collision warning, and blind-spot warning, the status of those safety systems during the failures is unknown — I had to complete long desert highway stretches fully manually, with repeated unrequested hand-backs of control creating a sudden-takeover risk. The fault is thermal-load related and intermittent: it recurred at high ambient temperatures, sometimes recovered after a rest or power-off reset, but on August 4 one full power-off reset at 88°f ambient failed to restore the system (it later self-recovered), suggesting progressive hardware degradation rather than ambient heat alone. Not yet reproduced by a service center: a Tesla service appointment is scheduled for August 13, 2026, and a service request with fault codes was filed in-app while the faults were active so remote diagnostics could capture them. No inspection yet by the manufacturer, police, or insurance. Public owner reports describe similar autopilot-computer thermal failures on hw3 vehicle.

On July 31, 2026, at approximately 12:55 pm, my 2026 Tesla Model Y experienced a severe safety defect while operating in full self-driving (supervised) mode. The vehicle completely failed to detect, slow down for, or stop at a clearly visible and unobstructed stop sign at an intersection. The vehicle attempted to proceed through the intersection without yielding. I was fully attentive with my hands on the wheel and had to instantly apply heavy manual braking and steering intervention to prevent a collision with an oncoming vehicle that had the right of way. This failure of the automated driving system to recognize fundamental traffic control devices constitutes an immediate and severe collision hazard.

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.

I was operating my Tesla using full self-driving (supervised) from my home to a coffee shop. The vehicle completed the entire drive under fsd without any manual intervention. After arriving at the destination, fsd automatically entered the parking lot, selected an available parking space, and initiated the parking maneuver on its own. I did not manually select the parking space or start the parking maneuver. During the automatic parking maneuver, the vehicle failed to detect a fixed square concrete bollard located within the parking space and continued moving until the front bumper made contact with the bollard, causing damage to the vehicle. No collision warning, parking collision warning, or automatic emergency braking occurred before impact. The vehicle remained under fsd control until the collision. The incident occurred in daylight with good visibility. The obstacle was a permanent concrete bollard, not a temporary object or a low parking curb. Dashcam footage of the incident has been preserved and has been provided to Tesla insurance. I believe Tesla should review the vehicle telemetry and fsd logs to determine why the system failed to recognize the fixed obstacle during the automated parking maneuver.

On or about xxx my Tesla Model Y downloaded fsd version 14 lite. One day after downloading the software, I used fsd and the new software caused the computer to overheat. This killed the car computer and made fsd, adaptive, cruise control, lane keep assist, reverse camera, and many other functions, including gps and navigation inoperable. My car’s warranty expired in January of this year and Tesla will not cover the replacement car computer. There are hundreds of other complaints of this issue reported online on [xxx], reddit, facebook, etc. In the 2nd quarter Tesla earnings call, [xxx] declared that hardware 3 equipped Tesla vehicles would not be able to support autonomous driving with full self driving. He stated every hardware 3 vehicle will need to be updated with a hardware 4 computer and cameras. Since my hardware 3 computer failed, I requested the hardware 4 computer and cameras to be installed, but Tesla denied this service even though [xxx] said it was a requirement.

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.

Tesla released a new version of fsd: 2026. 20. 6. 11 v14 lite for my 2022 Model Y long range. I installed it overnight and the next morning, several systems become intermittent. The backup camera stopped working immediately, and fsd would drop out, with the message "take control immediately". I would then lose traffic visualization and other advanced features. Eventually the system would recover and start the cycle all over again. Several times per drive. I took the car to the dealer and they diagnosed it as a failed hw3 computer. The cost to repair it was $2,939 out of pocket since my car was 2 months out of warranty. The car was 100% functional before the v14 lite update. The dealership denied the problem was related to the update, but the internet now has numerous instances of this problem, and attribute it to the computer running much hotter under this new update, causing components to fail. Our update was installed while the car was in our garage at a temperature in the 70’sf and immediately caused the computer failure before the car even left the garage. I requested and was given the failed computer in case any independent investigation is needed.

The vehicle's indirect tpms showed a "pressure sensor fault (may clear next drive)" without issuing any "low tire pressure" alert. On July 20, 2026, while driving, the rear right tire lost pressure and disintegrated over a 10-minute drive. Despite severe tire failure that triggered multiple safety system alerts (traction control, stability control, automatic emergency braking, and lane departure avoidance disabled), the vehicle software failed to issue a critical "do not drive" command or explicit "flat tire" warning. Furthermore, the official Tesla app automated response advised that "most alerts may resolve automatically on your next drive," encouraging continued driving. This total absence of critical emergency alerts and misleading system guidance created an extreme, life-threatening road hazard and resulted in severe tire and wheel destruction.

The contact owns a 2026 Tesla Model Y. The contact stated that while driving at an undisclosed speed with the full self driving mode activated, the vehicle struck the garage wall, damaging the rear passenger’s side door. No injuries were sustained. The contact stated that the dealer had previously provided mobile service to replace the camera and that a second dealer, Tesla white plains (250 tarrytown rd, white plains, NY 10607), had performed a hard reset on the vehicle due to phantom braking; however, the failure persisted. The dealer was made aware of the failure but canceled an upcoming appointment and informed the contact that there was no failure found. The vehicle was not diagnosed or repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 13,001.

I was driving at approximately 30-35 mph on a 30 mph residential road with my son in the front passenger seat. My vehicle unexpectedly collided with a parked, unoccupied car on the right side of the road, impact occurring between my front passenger side and the rear driver side of the parked vehicle. Following the initial collision, the vehicle continued past a small tree, mounted the sidewalk, and struck a second parked car before I was able to manually bring it to a stop 2–3 houses further down near an intersection. Throughout this sequence—with the vehicle traveling at ~35 mph—neither the automatic emergency braking (aeb) activated nor did any airbags deploy. Fortunately, neither my son nor I sustained catastrophic injuries, though my chest struck the steering wheel during the impact, causing ongoing pain my and mental trauma for my son. I am currently receiving medical advise. Given the speed and sequence of impacts, it is terrifying that the vehicle’s primary safety systems failed to engage before, during, or after the collision. I am seeking a thorough technical investigation into why automatic emergency braking and airbag deployment failed in this scenario with Tesla Model Y.

I was pushed to complete an update on my 2023 Tesla y with an over the air update. This happened last week. Following the update I have been getting a slew of errors when driving my car related to the parking break, brake functions, automatic energy braking and steering are affected. The wording on the app / car says, alerts - steering & braking - parking brake functions degraded / parking brake may not apply or release / parking brake may not apply or release. This causes my auto brake to not engage, my hold break to not engage, my parking brake to not engage. This causes my car to roll at stop / red lights. I have to physically slam by brakes to stop. This is extremely unsafe and Tesla is trying to charge me $130 to diagnose the car to see why the update caused the issue. My car went from fully drivable without any fsd, normal driving to a runaway trainwreck. This happens roughly 20-30 minutes randomly into driving. Not immediately and it is completely random.

7/17/26 about 8pm my Tesla Model Y backed into a wall under fsd (full self driving). The vehicle was placed into fsd to assist in backing the car from a narrow street into a garage space. Wall on one side and another SUV parked on the driver side. Driver was monitoring the vehicle maneuver forward and backward attempting to clear the wall so it can back into the space. The vehicle appeared to be close to the wall and I anticipated the vehicle to inch forward but instead the car went backwards into the wall and caused damage to my vehicle. The vehicle should have stopped and asked the driver to take over or alarms/chimes. The fsd system failed to recognize that the right rear would not clear the wall and still proceeded to reverse and cause damages.

This is what happened: while full self-driving (fsd) was engaged, the vehicle approached an intersection and appeared unable to correctly follow the roadway. Instead of following the intended road path, the vehicle continued forward, drove over the curb, and struck a road sign. The impact knocked the sign down, and the sign subsequently struck the vehicle, including the roof glass. The roof glass shattered and small pieces of glass entered the cabin, exposing both the driver and front passenger to a safety risk. Vehicle data obtained after the incident shows that the vehicle was in active_fsd leading up to the collision. Fsd changed from active to unavailable approximately 1. 5 seconds before the crash algorithm wake-up. Significant braking occurred only very close to the collision, and no automatic emergency braking intervention was recorded during the incident window. The data also shows multiple substantial steering movements shortly before the collision. Accelerator-pedal data does not establish driver acceleration as the cause of the collision. The available samples show an accelerator position of 2. 0% shortly before the collision and 0. 0% in the next recorded sample. The driver applied the brake shortly before impact. There were no prior warning lamps or messages indicating that fsd was about to become unavailable before the vehicle departed the roadway. The vehicle has been inspected/repaired following the collision, and vehicle data relating to the incident has been obtained and preserved. Police responded to the collision, and the incident was also reported to insurance. A police report was filed, and the case number is 2026-07160174. I have not yet received the formal cr-4 crash report. Following the collision, I experienced significant psychological distress and trauma-related stress symptoms as a result of the incident.

**incident report — Tesla Model Y safety system failure** the subject vehicle, a Tesla Model Y equipped with full self-driving (fsd) technology and advanced safety features, was involved in a collision at an estimated impact speed of 40–45 mph. The vehicle's onboard recording system captured the incident and clearly documents the impact dynamics, vehicle speed at impact, and the contributing actions of the other party involved. **incident details:** - **impact location:** left front side of vehicle - **impact speed:** 40–45 mph - **damage assessment:** vehicle declared total loss by insurance - **recorded evidence:** onboard system footage available **safety system failures:** despite the severity of the impact and speed involved, the following safety systems failed to activate: - emergency braking system did not engage - forward collision warning failed - seatbelt pre-tensioning/locking mechanism did not activate - airbag deployment systems failed (front, side, curtain, and knee airbags) **concern:** the vehicle's advanced safety features—which are primary design components marketed for collision mitigation—did not function as designed or expected. Given the impact speed and severity, these safety systems should have either mitigated the collision or deployed to protect occupants. The failure of multiple redundant safety systems raises questions regarding the reliability and function of these critical systems at the time of impact. **available evidence:** - onboard system footage (speed, impact angle, timing) - insurance total loss assessment - medical records (if applicable) - vehicle service history.

On i95 by the secaucus train station there is something sending a signal to my Tesla and other Teslas to disable all of its adas systems. All of the functionality related to adas gets disabled thus making the car very unsafe to drive. Due to this disability it also disables the camera systems in the car. So if an accident were to occur there would be no way to record.
