The FSD failed when it back into garage; the back of passenger side of the car hit the wall of garage. There is no warning before. Beacuse the distance for parking into the garage is small, there is no time to take over the FSD to avoid it happen. It happen around 23:35 on August 07, 2026. We reported as a safety incident to Tesla an hour ago. We updated the the software on August 02, 2026. The car had been succesful back into the garage more than ten times before.

On February 17, 2026, around 4:20 pm, as I was departing my agency's parking garage structure, my 2023 Tesla Y uncontrollably and un-prompted accelerated at a very high speed. I applied the brake and it would not stop. I nearly killed the security guard at the garage who was trying to direct my vehicle to the correct exit lane. The vehicle ran across a sidewalk adjacent to the garage, ran across a street, hit a street parking meter, ran across another sidewalk, ran across and toppled a perimeter fence around a parking lot across from the garage I exited, ran over concrete wheel barriers, and continued running for about 300 feet before it came to a stop on its own. This duration of this terrifying ordeal was 3 to 5 seconds. The air bags did not deploy. I called 911 repeatedly for Police investigation and report but the Police never showed up. I towed the vehicle to a Tesla Collision Center, which inspected and investigated the accident, and the Tesla Center stated that the FSD system was working properly and did not find anything wrong. I informed the Tesla Center that I did not subscribe to the FSD system service and was not using it during the accident, and they stated that they stand by the determination of their engineering division that reviewed the "blackbox", information gathering device of the vehicle. The vehicle was totaled and non-salvageable. Prior to the accident, the Tesla Collision Center, had repaired the vehicle from a previous accident that occurred on September 25, 2025. There were no warnings before the vehicle uncontrollably accelerated at a very high speed. I have copy of the accident videos. Your platform would not allow me to upload the videos.

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.

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.

Incident

Jul 17, 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.

Jul 12, 2026

I have reported safety issues on this vehicle before, but a new one has arisen which is related to the same. It is the computer shorting out. While in the past I have reported lack of backup camera, lane keeping, cruise control, collision avoidance, now intermittently the power steering fails. I get an error. Thankfully, this occurs when starting up and not while driving (yet), but it is nearly impossible to turn the wheel. As of now, exiting the car, letting the car doors lock and then coming back to the car has solved the issue, but I worry about this occurring while driving. Tesla knows about the computer issues and should take responsibility via a recall rather than a pricey repair on my own as this is a well reported issue. I have received no communication or feedback despite the complaints I have lodged with you and with Tesla. Please intervene before someone gets hurt.

Incident

May 4, 2026

While traveling on the freeway with Full Self-Driving (Supervised) engaged, my vehicle attempted to initiate an automatic lane change to the left. At that exact moment, another vehicle was already traveling parallel to me, fully established in the adjacent left lane. My vehicle signaled and immediately began veering directly into the occupied lane, completely failing to detect the car traveling next to me. The system did not abort the maneuver or yield to the existing traffic. To prevent an immediate sideswipe collision, I had to forcefully grab the steering wheel and wrench the car back into my original lane. The FSD system completely failed to monitor its immediate left blind spot.

Jul 20, 2026

On 07/16/2026, I was driving my 2023 Tesla Model Y when the vehicle suddenly began swerving rapidly left and right across multiple lanes without my intended steering input. The vehicle became difficult to control, and despite my attempt to correct the direction, it continued to move unpredictably and resulted in a collision. There were no prior warnings or indications of a steering or control issue before the incident. After the collision, I reviewed the Tesla USB drive and found that Dashcam and Sentry Mode recordings from immediately before and during the incident were not available; only recordings after the incident were present. I am concerned that a possible steering, electronic control, or software malfunction may have contributed to the loss of vehicle control.

Jul 16, 2026

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

Incident

May 18, 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.

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.

Incident

Jun 5, 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.

Jun 21, 2026

On June 23, 2026, at approximately 7:45 AM Central Time, I was operating my Tesla in full manual drive mode on US Highway 35 westbound between Denton and Fort Worth, Texas. No driver assistance, autopilot, or automated steering system was activated or engaged by me at any point prior to or during this incident. Without warning and without any driver input, the vehicle autonomously activated an automated steering and driving assistance system, assumed full control of the vehicle, and did not return manual control to me despite my attempts to intervene and regain control of the vehicle. The incident occurred during active rainfall and wet road conditions. The vehicle, while operating under its own autonomous system control without driver consent, drifted and struck the guardrail on the driver's left side. Following the initial impact, the vehicle continued moving and did not stop. The automated system remained active and did not disengage following the collision. The vehicle did not return control to me until a wheel separated from the vehicle. This incident was not caused by driver error. The vehicle's automated system activated without driver input or consent, overrode manual driver control, prevented the driver from regaining control of the vehicle, caused a collision with the guardrail, and continued operating after impact until mechanical failure occurred in the form of wheel separation. I am requesting a formal investigation into this uncommanded autonomous system activation as a safety defect. This type of failure poses an extreme and immediate safety risk to drivers, passengers, and the public.

Jun 19, 2026

The car's computer shorts out and disables all safety features including navigation, blind spot monitoring, all cameras, emergency braking, autopilot, lanekeeping, auto headlights and wipers. This is a known issue that Tesla will not repair. This resulted in a collision due to poor rear visibility, lack of cameras, and disabled emergency braking. In addition, intermittently there is loss of power steering. Despite this being a known issue, Tesla will not replace my computer, insisting I pay several thousands of dollars for the repair. I feel they must issue a recall and cover this safety defect. The car software cannot be updated, either. Please intervene.

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.

Incident

Jun 13, 2026

Component/Issue Description: Following a recent over-the-air (OTA) software update to the vehicle's Full Self-Driving system, a dangerous user interface defect was introduced. Immediately upon an FSD disengagement—the critical transition window where the operator must resume manual driving control—the center touchscreen populates a mandatory, invasive feedback popup menu. This menu causes a severe driver distraction and creates an immediate safety hazard. The popup blocks vital driving visualizations and navigation data on the screen at a high-stress moment. Furthermore, the UI creates a functional touchscreen lockout, demanding manual and visual interaction from the driver to clear the box while the vehicle is actively in motion. Forcing a driver to divert their eyes from the roadway to navigate a touchscreen menu immediately following a system intervention creates an unreasonable and systemic risk of collision. The manufacturer has provided no setting to disable this dangerous distraction.

I was driving my Tesla in self drive mode, and ibecause it started raining. I reduce the speed to standard. I had a notification on the screen, an alert in red. That the tesla reached the maximum speed in that mode “standard”. I was surprised and decided ti canceled the FSD feature and took control of the vehicle. Then when I was driving in the expressway very close to my exit on the right lane, the car accelerated by itself and turn to the left unexpectedly. I tried to returned the car to my lane and I never had control again of the car. Not the steering wheel, not the breaks responded. I was spinning on the expressway until I hit the concrete barrier with the rear bumper. Hopefully I did not hit any car nor they didn’t hit me. The car shutdown after the impact. Tesla sent me the footage of the impact, ignoring the moment that caused that incident that was some seconds before. The brakes were automatically turned onz and the wheels did not move. I know something wrong happened. Specially because the incident some minutes before when I was driving in standard mode and accelerated with no reasons. I have safety concerns. Also I noticed that after the last upgrades the car was havung navigation issues that I reported immediately when the autopilot was removed and we have to select the options.

On 05/31/2026, while Tesla Full Self-Driving (FSD) was actively engaged, the vehicle was taking the La Brea Avenue entrance ramp onto the I-10 freeway in Los Angeles, CA. FSD suddenly accelerated aggressively and the vehicle drifted hard to the left without any driver steering input. The driver was forced to hit the brakes and manually override steering to prevent a serious accident. The behavior felt like a system glitch. Both driver-side wheels sustained severe impact damage and are confirmed cracked. Tesla Service Center confirmed the damage in writing on 06/08/2026 and quoted $2,325.74 in repairs. This dangerous FSD behavior matches the pattern currently under active NHTSA engineering analysis.

1. Failed Component/System: The failed system is the Tesla Full Self-Driving (FSD - Supervised) software and its underlying vehicle control logic, specifically resulting in an uncommanded torque request (Sudden Unintended Acceleration). 2. Safety Risk: The vehicle engaged in Sudden Unintended Acceleration (SUA) in reverse from a complete stop, without any driver pedal input. In a parking environment, this uncommanded acceleration poses an extreme and immediate threat to life safety. Had a pedestrian, child, or another moving vehicle been behind my car instead of a metal pillar, this software malfunction would have resulted in severe injury or a fatal collision. 3. Inspection Status: The vehicle has not yet been inspected by the manufacturer, police, or insurance representatives. I am intentionally securing the vehicle to preserve the crucial diagnostic logs and EDR data from being erased or reset during standard repair procedures, pending official data extraction. 4. Warnings/Symptoms: There were absolutely no warning lamps, error messages, or visual/audible symptoms prior to the failure. Furthermore, during the uncommanded acceleration, the system did not issue an FSD disengagement warning or chime. The dashcam footage confirms that the FSD visualization remained active and blue on the screen throughout the entire unintended acceleration event up until the impact.

UPDATE to previous complaint – Reference Number: [XXX] VIN: [XXX]a [XXX] UPDATE to my previous NHTSA complaint regarding sudden unintended acceleration in my Tesla Model Y (VIN: [XXX] ) I previ[XXX]sudden acceleration incident on [XXX], at [XXX] 4 parking garage ramp. Tesla has now provided the Vehicle Data Report and EDR data (Case # [XXX]). The data shows accelerator pedal position increasing to 100%, with brake input occurring late. However, I am 100% certain that I did not press the accelerator pedal at any time. I have a clean driving record of over 27 years. This discrepancy between the logged data and actual driver input strongly suggests a potential safety defect in the accelerator pedal sensor system (both redundant sensors), drive-by-wire system, or brake override / Automatic Emergency Braking functionality. Attachments included with this update: Tesla Vehicle Data Report (VDR) Tesla EDR Report High-resolution photos of vehicle damage and airbag deployment I request that NHTSA review this additional technical information as part of their evaluation for a possible safety defect investigation.

I have written several times before about my car's phantom braking in cruise control. When the Santa Fe Tesla dealer, where I bought the car, told me recently that the problem had been fixed, I was disappointed they didn't bother to tell me, but thrilled to hear the news. On May 12-13 I drove over 900 miles. I tried cruise control for significant portions of both drives and did not experience one problem. Finally, I thought, they fixed the problem...and how nice it was to have cruise control for extended drives. Not so soon: on May 19th I was driving 2 friends up to volunteer at the Wildlife refuge on I-25 in northern New Mexico. The phantom braking happened again. My friends were dismayed...one thought I had seen something in the road that she didn't see. The other, in the back seat, tried to understand what happened. Please, this is beyond the pale! Of course I will call and take the car in to the dealer...an hour's drive for me. I will be surprised if they fix it, and if they do it under warranty. I did just buy new tires (see previous report about original tires with multiple flats and not even making it to their 40,000 mile warranty) so I'm no longer worried about getting a flat in the rural areas where I live and drive.

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

On Saturday 16th Oct 2026 around 10 AM EST, while driving down the ramp from Parking Floor 2 to Parking Floor 1 in the JFK Terminal 4 Short Term Parking garage (John F. Kennedy International Airport, New York), the Tesla vehicle suddenly accelerated forward very fast on its own without any input on the accelerator pedal. Either I was not pressing the gas pedal at the time, or I was slowing pressing as the car was going down on ramp. The car surged ahead with significant force and struck a fence at the bottom/end of the ramp area. There were two passengers in the vehicle. No other vehicles were involved. The impact caused: My Tesla Model Y to sustain severe front-end damage and appear to be a total loss. Injuries to both passengers. Minor scratches on my hands. Sequence of Events: I was driving the vehicle at low speed down the ramp from Parking Level 2 to Level 1 in JFK Terminal 4 Short Term Parking. Without pressing the accelerator, the car unexpectedly accelerated. Braking did not prevent the impact. The vehicle came to a stop only after hitting the fence. Today, I have reported this as a sudden/unintended acceleration event to Tesla and requested a full vehicle data log review. I would like Tesla to investigate following. 1. Why the car suddenly accelerated on very speed? 2. Why the steering got locked when it happened? 3. Since it is the closed parking lot, why Tesla did not stop automatically before hitting fence? I have been driving for more than 27 years, I never had any accident, and I never got any tickets in last 27 years.

The full self driving system has malfunctioned and is failing. I was put in incredibly dangerous situations that were near potentially fatal accidents. Had someone been a little bit closer when following me, I would not have had enough time to counter the issue. Yes it has been confirmed but not nearly to the extent that I have experienced it It has been inspected by a local service center from the company. There have been some visibility warnings but nothing else.
