Vehicle Speed Control Problems of Tesla Model Y - part 1

Phantom braking while using the tacc on the Tesla.

While exiting a drive-thru, I pressed the accelerator and the vehicle unexpectedly accelerated at a high rate of speed on its own. I attempted to brake, but the brakes did not respond. The vehicle struck a concrete median. Police report on file: east hanover township pd, case #2026-12503.

The contact owns a 2026 Tesla Model Y. While the vehicle was parked and attempting to shift into drive(d), the brake pedal was depressed, and the driver attempted to select the gear, but the gear display icon appeared semi-transparent. The driver was able to select the intended gear after several attempts; however, upon depressing the accelerator pedal, the vehicle unintentionally accelerated at a higher speed and struck a tree. The air bags did not deploy. No injuries were reported, and a police report was not filed. No warning light was illuminated before or after the crash. Full self-driving (fsd) mode was not activated during the failure. The vehicle was driven to a collision repair center to repair the damage. The contact notified the manufacturer of the failure and requested assistance retrieving data from the event data recorder (edr); however, no assistance was provided. The vehicle was not diagnosed or repaired for the unintended acceleration. The failure mileage was approximately 2,000.

I was operating my Tesla using full self-driving (supervised) when the vehicle approached an active school zone with flashing warning lights and a posted school-zone speed limit of 35 mph. Fsd did not appropriately respond to the active school zone or reduce the vehicle's speed to the posted 35 mph limit, requiring me to disengage fsd and manually slow the vehicle. The incident was captured on the Tesla dashcam. The recording shows fsd active while approaching the school zone. At approximately 14 seconds into the recording, the vehicle was traveling approximately 52 mph with "self-driving" displayed while the flashing school-zone warning and school pavement markings were visible ahead. The posted school-zone speed limit is 35 mph when the warning lights are flashing. Because fsd was not slowing the vehicle appropriately, I intervened and disengaged fsd. Immediately following my intervention, vehicle speed decreased from approximately 49 mph to 39 mph, 31 mph, and approximately 29 mph as I manually slowed the vehicle. This was the second time I experienced fsd failing to appropriately respond to this same active school zone. After this occurrence, I saved the dashcam recording and submitted a bug report through the vehicle. There were no warning messages indicating that fsd could not recognize or respond to the school zone. My safety concern is that fsd may proceed into an active school zone substantially above the posted school-zone speed limit unless the driver recognizes the failure and intervenes. The original dashcam recording is available and documents the vehicle speed, fsd status, active flashing school-zone warning, posted speed limit, and timing of my intervention.

I own a 2021 Tesla Model Y with an hw3 car computer. At approximately 54,000 miles, the vehicle developed intermittent failures of the cameras, gps/navigation, and cruise control. On two occasions during the same routine drive, about 40 minutes into the trip, the gps, cameras, and cruise control abruptly stopped functioning at approximately the same location. The first occurrence was about July 7, 2026 at 9:15 am and the second August 7, 2026 at about 3:15 pm. I made the same trip once between these events without a failure. I had also previously experienced a frightening incident while driving northbound on I-280 approaching the lane division for 19th avenue in san francisco using autopilot. Where my lane widened and a new lane began, the vehicle abruptly attempted to follow the new lane to the right. I had to intervene firmly with the steering wheel to maintain control. I do not know whether this event was related to the later diagnosed computer failure, but report it because of its possible safety significance. Tesla serviced the vehicle in sunnyvale on August 16, 2026 at 54,565 miles. Tesla's invoice states: “technician addressed the intermittent loss of gps, cameras, and cruise control. The car computer had board-side failures and was replaced. ” Tesla replaced the hw3 computer with a hardware 3. 2 computer, part 1775000-s0-l. Tesla also found corrosion at the 12v input and replaced the 12v battery. My concern is that the hw3 computer failure was intermittent and simultaneously affected cameras, gps/navigation, and cruise control. The vehicle operated normally between failures, so a driver could not know when the problem might recur. I ask NHTSA to determine whether similar hw3 computer failures are occurring in other 2021 Model Y vehicles.

Separately, the system could not hold a consistent speed on open highway with no vehicle ahead. It would surge from a set 70 mph to roughly 72-73 mph and then drop back, repeatedly, producing a pulsing acceleration and deceleration. The system also hesitated frequently and issued repeated audible alerts without an identifiable hazard present. I previously filed a complaint regarding phantom braking on this same vehicle (odi number 11450326, filed February 4, 2022), which described nearly identical behavior triggered by trucks on the same georgia-to-new jersey route. That complaint concerned fsd/autopilot software from 2022. The behavior described here occurs on Tesla’s current v14 lite software released to hardware 3 vehicles in July 2026. The defect has persisted across more than four years and multiple software generations. Unexpected hard braking at highway speed with no hazard present creates a rear-end collision risk to my vehicle and to following traffic.

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

Component/system that failed: the service brakes failed to stop the vehicle. While reverse-parking at low (parking) speed, I applied the brake pedal and the vehicle did not stop as expected, resulting in contact with an object and vehicle damage. The vehicle is available for inspection upon request; it has been preserved and driven only minimally since the event. How safety was put at risk: the brakes failed with no warning. Had a person been behind the vehicle, the failure to stop could have caused injury. This is the only vehicle for a family with three children who are regularly transported in it, and I no longer feel safe driving them. Reproduced/confirmed by a dealer or service center: not yet. Inspected by manufacturer/police/insurance/others: the insurer opened and then denied the claim and stated that no vehicle telemetry/data was available to preserve. No independent forensic inspection has occurred yet. Police did not attend. Warning lamps/messages/symptoms prior to failure: none. There was no warning light, no alert message, and no audible signal before or during the event. The parking sensors did not beep as they normally do. No abs or brake warning light appeared at any time before or after. Additional relevant detail: approximately one week earlier, the front lower control arms were replaced. It is unknown whether the abs wheel-speed sensor or related wiring was affected; the vehicle displayed no related warning at any time. No injuries occurred.

Tesla took off from a parking lot and was uncontrollable, went through the grass, crossed the street and construction before hitting the barricades and fell into a sewer as the road ended there. There were 2 passengers in the car and luckily both passengers came unharmed. But fsd needs to be investigated on why this happened.

Tesla's fsd system has zero opportunity for the driver to adjust what the car believes is the speed limit. My car often has no idea what the speed limit is. More often than not, it believes the speed limit is lower than it actually is, by as much as 30 mph. This causes the car to impede traffic if I do not intervene. I can press and hold the accelerator to force the car to drive the speed limit, however I am then faced with a warning that the car will not automatically brake in an emergency. I run my car in "sloth" or "chill" 99% of the time to prevent speeding (something you should actually enforce), and this is really where the issue becomes somewhat problematic. If I'm on a 55 mph road driving 55-57 and the car suddenly decides the speed limit is 30, in sloth, it will decelerate aggressively, making people behind me think I'm nuts. . . Could potentially be dangerous. Recently I was on a "new" road into a campground, a couple days after school ended and there were children around, the speed limit on the road is posted at 20. . . The car said [xxx], and proceeded to accelerate aggressively of course I terminated the fsd session and just drove the car myself. But no matter which way it is, it's insane that I cannot adjust the speed limit to whatever the speed limit actually is. I own this car, and I pay for fsd for one reason, I'm getting older [xxx], and my driving skills and reflexes are not what they used to be. I'm spending my money to increase safety. . . Please insist that Tesla allow us to adjust the speed limit, or provide a way to get them to do it in a timely manner. I report these situations to Tesla often. . . Not once have they adjusted whatever they use in the background. . . Same problems on the same roads over and over and over, day after day. Please force them to do the right thing! information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

June 30, I was driving an highway, PA 376 during a rain storm, fsd 60 mph 4-5 pm. The rain was heavy, vehicles in front of me flashing their emergency lights, I attempted several times to slow down, acceleration modes, towards me. Vehicle would not slow down, heavy rain and puddles blurred my vision, thinking I would rear end the vehicle in front of me. Traffic was light due to the rain, fsd needs better software to slow down during weather conditions.

The contact owns a 2024 Tesla Model Y. The contact stated that while driving 25 mph and making a right turn into an alley with another vehicle approaching, the contact stopped to reverse; however, while using the tap feature, the vehicle unintendedly accelerated and crashed into a concrete barrier twice. The vehicle was uncontrollable. The contact stated that the air bags failed to deploy. The crash was not captured on the camera inside the vehicle. A police report was filed. There was no injury reported. The vehicle was towed to a towing lot and was next towed to the local dealer but was not yet diagnosed or repaired. The manufacturer was not contacted. The approximate failure mileage was 14,000.

• fsd received a software update earlier this same morning. • while navigating a parking garage under fsd, the vehicle initiated an unprompted reverse maneuver. • the reversal happened with no warning and no meaningful time for driver intervention before impact. • the vehicle struck a structural beam, causing damage to the vehicle above the rear driver side door, as well as shattering and causing splintering of the roof glass.

I was using the Tesla fsd in stop and go traffic. At the moment I was moving with traffic at about 30 mph and then traffic started slowing down. The vehicle in front of me came to a complete stop. The fsd on my car started slowing down, but not fast enough. It rear-ended the vehicle at about 18 mph.

I am submitting this complaint to request an investigation into a serious safety defect involving my Tesla vehicle. On multiple occasions, the vehicle has experienced a significant and unexpected loss of acceleration when I attempted to enter or cross intersections. Despite pressing the accelerator, the vehicle failed to respond as expected, leaving me unable to accelerate normally while entering active traffic. This is not a minor hesitation or inconvenience. It is a serious roadway safety hazard. Drivers rely on immediate acceleration when crossing intersections, turning across traffic, or merging. A vehicle that unexpectedly limits acceleration can place occupants directly in the path of oncoming vehicles, creating a substantial risk of a severe collision, serious injury, or death. I reported this issue to Tesla service and provided multiple timestamps documenting the events. Tesla was unable to identify any fault codes or provide a diagnosis and indicated that because no fault was recorded, the issue could not be confirmed. Through independent research, I found numerous reports from other Tesla owners describing substantially similar acceleration limitation events. Many reports specifically reference obstacle aware acceleration as a possible cause, and some owners report that disabling the feature resolved the issue. If a safety system can falsely detect an obstacle and reduce acceleration while a driver is actively entering an intersection, the system itself may create a greater danger than the one it is designed to prevent. I respectfully request that NHTSA investigate whether Tesla vehicles are experiencing unexpected acceleration limitation or torque reduction during intersection entry and traffic merging situations, evaluate the role of obstacle aware acceleration and related software systems, determine whether a broader pattern exists, and assess whether corrective action or a recall is warranted. This could cause serious injury or fatal crash.

On xxx at approximately 9:30am, my 2026 Tesla Model Y suddenly accelerated without driver input while parking at the center at [xxx], [xxx]. Vehicle surged forward unexpectedly. I immediately applied brakes. No warning messages appeared before or during the incident. Vehicle struck parking lot curb. Police responded and vehicle was towed. Physical evidence including tire drag marks and vehicle debris remain at scene. Requesting full edr data log preservation. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

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.

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.

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.

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

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.

Update to previous complaint – reference number: [11738920] VIN: [xxx] case: Tesla [xxx] update to my previous NHTSA complaint regarding sudden unintended acceleration in my Tesla Model Y (VIN: [xxx] ) I previously reported a 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. Btw, it is really difficult to contact Tesla to report such incidents. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

I am writing to formally raise a serious concern regarding the functionality of Tesla’s full self-driving (fsd) system. On may 11th, while the vehicle was operating under fsd, I experienced an unexpected disengagement of the system, which then reengaged on its own without any input from me. This erratic behavior caused the vehicle to hit the garage door and resulted in a crash.

The Tesla autosteer (equivalent of adaptive cruise control) failed to brake on seeing the car ahead braking. In the 5 seconds before impact, the car ahead had started braking. The autosteer did not brake for the first 3 seconds and then it asked me to take over 2 seconds before collision. It did not apply automatic emergency braking causing me to rear end the car ahead of me on the freeway at around 30mph this is supposed to be a safety driver assist feature which instead was the primary cause of the accident. The take control was too late to avoid collision. This is a serious safety issue.

The contact’s wife owned a 2022 Tesla y. The contact stated that while the vehicle was parked, his wife shifted the gear shifter into drive(d), and the vehicle independently accelerated. The autonomous feature was not engaged. The brake pedal was depressed; however, the vehicle failed to respond as needed, and the front center of the vehicle crashed into a pile of cinder blocks, drove through a gate, and crashed into a dumpster, where it came to a stop. As a result of the impact, the front driver's side tire detached, and the dumpster was damaged. The contact stated that another person helped remove the driver from the vehicle due to the front driver door being unable to open. The air bags deployed as intended. No warning lights were illuminated. The vehicle was towed to a tow yard and was deemed a total loss. A police report was filed. The driver had pain in the back and sought medical attention. The contact's wife was informed of a slight fracture of an unstated bone in her back and ribs, and had to return to the doctor several times for medical assistance. The contact was certain there was no user error to have caused the crash the manufacturer was notified of the failure. The failure mileage was unknown.

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

Safety defect complaint – Tesla Model Y fsd v14. 2. 2. 5 I am reporting unsafe speed behavior in Tesla Model Y full self-driving (fsd) software v14. 2. 2. 5. Fsd uses selectable driving profiles (sloth, chill, standard, hurry, mad max) to control speed, but provides no definition of how these profiles affect speed or limits. Tesla also removed the ability to manually adjust speed incrementally, reducing driver control. While in standard mode, the vehicle exceeded the speed limit by 12 mph, resulting in a photo radar citation. This was not driver-initiated. I have experienced at least six incidents where the vehicle exceeded the speed limit by 10+ mph without warning. Two design issues create significant safety risk: the right scroll wheel now controls both microphone and fsd profile selection. Its multi-directional design allows unintended inputs that can change speed profiles (e. G. , to hurry or mad max) without driver awareness. There is no audible or visual alert when this occurs. The vehicle can accelerate beyond safe/legal speeds before the driver realizes and disengages fsd. The driver-set speed warning (set to 8 mph over limit) failed to activate during multiple overspeed events, including the citation incident, despite being enabled. This removes a critical safety safeguard. Speed increases have occurred both gradually and rapidly, reducing reaction time. Safety risk: unintended acceleration, loss of predictable speed control, lack of driver alerts, and failure of safety warnings. These conditions could lead to violations or collisions. I request NHTSA investigate whether this constitutes a safety defect.

The contact owns a 2026 Tesla Model Y. The contact stated that while attempting to park the vehicle suddenly lurched forward and crashed into a curb, then the vehicle lunched forward and crashed into a brick wall. The vehicle then erroneously drove in reverse at a high rate of speed and crashed into a second parked vehicle. The contact indicated that after the incident, in order to shut the vehicle off, the doors had to be opened. The contact's foot remained on the brake pedal during the incident. During the crash, the driver sustained a fractured right foot, and the rear center passenger sustained a bruised back. Both injuries later required medical treatment. No police report was taken. The vehicle was later towed to the home. The cause of the failure was not determined. The manufacturer and local dealer were notified of the failure. The failure mileage was 9,440.

### summary: sudden unintended acceleration (sua) from a stationary position. ### vehicle configuration: 2023 Tesla Model Y long range awd. Battery type: nmc. ### incident details: on April 19, 2026, at approximately 10:00 a. M. , the vehicle was stationary on a flat surface at 6722 vista del Mar Ave, san diego. I was in the driver's seat with the vehicle "on" but stopped, conversing with two witnesses. My feet were completely clear of both the accelerator and brake pedals. ### the event: without driver input, the vehicle suddenly and forcefully accelerated forward. I immediately slammed the service brake with full force. The vehicle traveled approximately 20 feet before the brakes brought the car to a halt. ### evidence & gaps: two eyewitnesses confirmed the vehicle moved autonomously without pedal interaction. A manufacturer data report was requested, but it showed a specific data gap for the exact seconds of the acceleration event, despite providing second-by-second logs for the rest of the day.

Incident date: April 11, 2026 approximate time: 6:30 pm component(s): unknown (suspected: electronic stability control, steering, adas) description of incident: on April 11, 2026, at approximately 6:30 pm, I was operating my Tesla Model Y on a highway with a self-driving mode engaged. I experienced what appeared to be a sudden, unintended acceleration combined with an erratic "zig-zag" steering pattern across multiple lanes. I am not certain of the technical cause, but the vehicle’s behavior felt like a loss of system control that was not initiated by me or the road conditions. I had to intervene immediately to prevent an accident. Post-incident actions and manufacturer contact: I have since contacted Tesla service, and while they confirmed that data for that date exists, my formal "privacy data" requests for those specific logs have come back empty or missing the relevant timeframe. Summary of concern: I am reporting this because I suspect a serious software or hardware malfunction occurred, though I do not have the technical diagnostic to confirm which system failed. The combination of the vehicle’s erratic movement and the subsequent difficulty in obtaining the data logs for this specific window of time leads me to believe there is a potential safety defect that requires investigation.

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

I am writing to bring to your immediate attention a serious safety incident involving our brand?new 2026 Tesla Model Y (juniper), equipped with fsd version 14. 2. 2. 5 and software version 2025. 45. 10. We purchased this vehicle as our dream car, and for nearly six months it delivered exactly what we hoped for—innovation, safety, and an exceptional driving experience. That trust was the foundation of our decision to choose Tesla. On [xxx], at approximately [xxx] in frisco, TX, that trust was shaken by a sudden and alarming event. After coming to a stop and while making a routine right turn at under 10 mph, the vehicle unexpectedly accelerated on its own, causing an immediate loss of control. The entire incident unfolded in seconds, leaving no opportunity to react or correct the vehicle’s behavior. The incident happened at the intersection of [xxx]. The "autopilot" feature in Tesla was on at the time of the incident. The impact was severe. The airbags deployed, the vehicle was declared a total loss by insurance, and first responders—including the frisco police department—were required to clear the wreckage. My wife sustained injuries in the crash and continues to recover. Witnesses at the scene confirmed that the acceleration was abrupt and not driver?initiated. The emotional and physical toll has been significant. More importantly, the nature of this incident raises serious concerns about a potential safety issue that could affect other Tesla owners. We feel compelled to ensure this incident is thoroughly examined. If there is a systemic issue—software?related or otherwise—it is critical that it be identified and addressed to protect other drivers and uphold the integrity of the Tesla name. We truly miss our vehicle and the confidence we once had in it. We hope Tesla will treat this matter with the seriousness it deserves and provide a transparent path forward. Thank you for your time, attention, and commitment to safety. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

Vehicle will suddenly apply brakes while using standard cruise control for no apparent reason. This is extremely dangerous as it has almost caused several accidents on the highway. I have almost been rear-ended several times. This is a very common problem and well documented problem referred to as "phantom braking" on Teslas and something needs to be done immediately.

I was at full stop on [xxx] facing [xxx] at a red traffic signal at intersection. Then while still at light which was red the vehicle unexpectedly accelerated toward [xxx] on its even with feet on brake, I attempted to maneuver to avoid colliding with vehicles traveling on [xxx] , then made a sharp right turn on sidewalk of [xxx] drove striking a "bee line bus" sign located in front of [xxx] . I was able to maneuver not hitting any pedestrians and crashing vehicle out a brush on sidewalk without putting passengers/family in car at risk of injury information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

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.
