| May 2026 | STRUCTURE,BACK OVER PREVENTION | 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. | Crash: Yes Fire: No | Unknown |
| May 2026 | VEHICLE SPEED CONTROL,ENGINE | 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.

| May 2026 | SERVICE BRAKES,FORWARD COLLISION AVOIDANCE | 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. | Crash: No Fire: No | Unknown |
| May 2026 | UNKNOWN OR OTHER,FORWARD COLLISION AVOIDANCE | 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. | Crash: No Fire: No | Unknown |
| May 2026 | STEERING,SUSPENSION | While driving, a critical heavy-duty front lower control arm / lateral link bolt completely detached from my vehicle and was found intact on the ground with factory green threadlocker still visible on the threads. The undercarriage and chassis show absolutely ZERO signs of external impact, scrape, or road hazard damage. This structural failure caused an immediate, severe safety hazard, rendering the vehicle completely unsafe to drive due to a catastrophic risk of wheel separation and total loss of steering control. This exact component failure is identical to Tesla's historical safety recalls, specifically NHTSA Recall Campaign Number 21V835000 and its expansions, which explicitly state: "the front suspension lateral link bolts may not have been secured to the correct specifications... causing the fasteners to loosen over time and separate from the sub-frame." Because the bolt loosened and fell out over time due to insufficient factory torque, the loose component put uneven mechanical stress on the lower control arm, resulting in the complete failure and damage of the control arm assembly. Tesla Service Center has refused to honor this as a latent manufacturing defect, hiding behind warranty expiration. They have unconscionably misclassified a known, life-threatening production defect as standard "wear and tear," forcing me to pay a $265 diagnostic fee and the full cost of a complete control arm replacement under protest. I am filing this report because Tesla is actively endangering consumers by failing to expand their suspension fastener recall to cover vehicles experiencing the exact same catastrophic manufacturing defect outside the arbitrary warranty period. NHTSA ODI complaint records show multiple substantially similar failures outside Tesla’s recall VIN population, including ODI Nos. 11630487, 11554803, 11494976, 11493354, 11486040, 11689987, 11675200, and 11632785 for Model Y vehicles, and ODI Nos. 11720800, 11705487, 11675676, 11664858, 11637813, etc | Crash: No Fire: No | Unknown |
| May 2026 | STEERING,SUSPENSION | While making a normal right turn at low speed in a residential neighborhood, I heard knocking sounds from inside the vehicle and immediately lost steering control. I had to physically force the wheel back into position to regain control of the car. After the initial incident, every right turn and brake application produced a loud rubber grinding sound accompanied by significant loss of steering control. The vehicle was completely unsafe to drive. Tesla previously issued recall SB-22-31-002 for 2023 Model Y vehicles for improperly torqued front lower lateral link fasteners at the factory which are the exact same components that failed on my vehicle. Tesla confirmed my VIN was not included in the recall. The vehicle has been driven normally with no accidents or abuse. Mileage at time of failure was approximately 58,000 miles. | Crash: No Fire: No | Unknown |
| May 2026 | STEERING,SUSPENSION | Bolt fell out of the lateral control arm on the front left wheel. Car was inoperable. | Crash: No Fire: No | Unknown |
| May 2026 | UNKNOWN OR OTHER,VISIBILITY/WIPER,FORWARD COLLISION AVOIDANCE | 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. | Crash: No Fire: No | Unknown |
| May 2026 | STEERING,VEHICLE SPEED CONTROL,ENGINE | 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. | Crash: Yes Fire: No Injuries: 3 Towed Medical attention | Unknown |
| May 2026 | FORWARD COLLISION AVOIDANCE | Whenever Autopilot is disengaged by the driver, a pop up multiple choice question appears on the screen covering critical car information with no way to get past it except reading and answering the multiple choice question while you are driving. You have to take your eyes off the road to answer the question, it's about the dumbest most unsafe thing I've ever seen from a car company. Please require them to fix it immediately, and apparently a rule needs to be written that pop ups on cars are illegal. | Crash: No Fire: No | Unknown |
| May 2026 | SUSPENSION | Clicking/thumping on sharper turns a day before the issue. Then today, there was a loud clunk while driving. When I was reversing into my driveway, there was scraping noises and resistance. Upon exiting the vehicle, I saw the passenger side front control arm loose. It is now inoperable. | Crash: No Fire: No | Unknown |
| May 2026 | STEERING,FORWARD COLLISION AVOIDANCE | Nature of Defect: While operating Full Self-Driving (FSD) at highway speeds, my vehicle exhibits involuntary lateral swerving — sudden, uncontrolled movement to the left and right without driver input. This behavior occurs repeatedly and unpredictably, posing a direct safety risk to the occupants of my vehicle and to other drivers. Tesla Service diagnosed the root cause as a failed FSD computer and recommended full replacement at a cost exceeding $3,000. Crashes or Injuries: None to date, though the behavior described above creates a significant risk of collision at highway speeds. Frequency: Recurring during FSD engagement at highway speeds. Additional Context: This defect was present during my vehicle's original warranty period. Tesla has been aware of this issue since my service visit and has not completed the repair. I have an active goodwill warranty request pending with Tesla that has gone unacknowledged for over two weeks. I am submitting this complaint because I believe this defect may affect other Tesla vehicles equipped with the same FSD hardware, and I want NHTSA to have a record of this failure mode. | Crash: No Fire: No | Unknown |
| May 2026 | SEAT BELTS | I lease a 2023 Tesla Model Y. The rear passenger side seat belt/buckle assembly had previously experienced issues involving unexpected disengagement/unlatching. The vehicle was previously brought to Tesla for service regarding the restraint system/rear passenger buckle area and Tesla represented that the issue had been addressed. On April 4, 2026, during an emergency braking event to avoid another vehicle that abruptly cut in front of me and slammed on its brakes, I was forced to brake hard and maneuver to avoid a collision. During that braking event, the rear passenger side buckle released/unlatched while my child was properly secured in a child safety seat in that seating position. As a result, the entire child safety seat violently pitched forward and my child’s face struck the seat in front of her. This incident occurred after Tesla had already been given notice of restraint system concerns involving this seating position and after prior service attempts. The issue raises serious concerns regarding rear passenger restraint integrity and child occupant safety during emergency braking situations. Tesla was formally notified again regarding this incident on May 12, 2026. As of the date of this complaint, approximately one week has passed and Tesla has not responded or attempted contact regarding the reported child occupant restraint failure. The vehicle has not yet been reinspected by Tesla following this incident and remains available for inspection. I am requesting preservation of all vehicle telemetry, restraint system data, diagnostic information, and service records related to this vehicle and prior restraint system complaints/repairs. | Crash: No Fire: No Injuries: 1 Medical attention | Unknown |
| May 2026 | SUSPENSION | Vehicle brought to Tesla Service Plano TX for front-end rattle on bumpy roads at 49,951 miles. Technician found right front compliance arm split, left front compliance arm tearing, right front aft link starting to wear, left front aft link split at bushing, rear bolt for link loose, and opposite side nut separated from the subframe causing bolt to have zero tension. Tesla replaced entire front subframe assembly, both front lower lateral links, and both front lower compliance links under Basic Vehicle Limited Warranty. During the same visit, the technician performed a Vehicle Health Check (form SC-25-00-016 R2) and documented additional rear suspension defects: rear lower fore links have play and rear upper fore link bushings have excessive travel. Technician marked the suspension section as Repair/Replace. Service center declined warranty coverage on the rear, calling it normal wear despite the technician's findings. This is the second major warranty visit. At 14,928 miles in September 2024, Tesla Austin replaced the Power Conversion System, 16V Li-Ion battery, and pyrotechnic battery disconnect due to a loose harness connector causing vehicle shutdown warnings. Vehicle was manufactured at Tesla Gigafactory Austin TX. A separated subframe nut is a structural safety defect that could result in wheel alignment shift and loss of vehicle control. I drove this vehicle with my family including two children before the defect was discovered.

| May 2026 | SERVICE BRAKES | Purchased used 2023 Tesla Model Y from Tesla on April 17, 2026 at ~16,300 miles. Pre-delivery, Tesla notified me by text that the vehicle failed state safety inspection due to front upper ball joint play (a known Tesla Model 3/Y defect). Tesla repaired it at its own service center and certified it as passing on April 8, 2026. No warning lamps or messages. ~12 days post-delivery a family member reported a noise from the left rear; the vehicle was then parked. On May 10, 2026, I removed the left rear wheel and found the left rear brake caliper completely detached from the rear knuckle. Both caliper bracket mounting bolts were missing. The caliper was held only because it had seized on the rotor. Vehicle unsafe to operate. Towed by flatbed to Tesla May 11; available for inspection on request. Properly torqued caliper bracket bolts do not back themselves out in ~800 miles of light use. Realistic causes: (a) bolts installed but not torqued to spec, worked loose in service; (b) bolts missing at state inspection and certified anyway; (c) suspension disassembled during the pre-sale repair, bracket reassembled with bolts omitted. All implicate Tesla's workmanship; (b) and a visibly-loose (a) also implicate the inspection. Tesla previously acknowledged this failure mode in recall SB-21-33-002 ("Loose Brake Caliper Bolts," 2019-2021 Model 3 / 2020-2021 Model Y): caliper bolts "may not be torqued to internal specifications" and "may be loose, allowing the brake caliper to separate." My vehicle is outside that range but the recall shows this is a known Tesla pattern. Risk: caliper detachment can wedge the wheel, lock the brake, damage tire/wheel, boil brake fluid, or break free at speed — any can cause loss of control. Vehicle driven ~800 miles in this condition. Dealer confirmation pending; Tesla instructed in writing not to repair pre-inspection. State Police ASED complaint filed; formal dispute filed with Tesla Resolutions. | Crash: No Fire: No | Unknown |
| May 2026 | FORWARD COLLISION AVOIDANCE | I would like to report a serious safety concern regarding Tesla Full Self-Driving (FSD) on HW3-equipped vehicles. My vehicle repeatedly performs sudden and aggressive braking while FSD is engaged, even when there are no visible obstacles, vehicles, or hazards ahead. In some cases, the vehicle slows dramatically or comes to a complete stop unexpectedly. This creates a significant rear-end collision risk, especially on higher-speed roads where surrounding traffic does not anticipate abrupt braking behavior. This issue has been occurring for approximately one year and appears to have worsened over time and TESLA hasn't released a single FDS software update for over a year for HW3 vehicles. I recently brought my vehicle to Tesla service, paid for diagnostics/repair, and the issue still remains unresolved. I have also personally experienced the same behavior in another HW3 Tesla vehicle provided as a loaner from a Tesla service center, which suggests the issue may not be isolated to my individual car. Based on my experience, this appears to affect multiple HW3 vehicles operating with FSD enabled. The unsafe braking behavior causes surrounding vehicles to tailgate closely and react suddenly, increasing the likelihood of accidents. In my opinion, the current FSD behavior on affected HW3 vehicles presents a safety hazard for both Tesla owners and other road users. I believe this issue warrants immediate investigation. Until the root cause is identified and corrected, Tesla should consider disabling or restricting FSD functionality on affected HW3 vehicles to reduce the risk of accidents caused by phantom braking and unsafe autonomous driving behavior. | Crash: No Fire: No | Unknown |
| May 2026 | ELECTRICAL SYSTEM | On May 8, 2026 at approximately 1:15 PM in [XXX] , my 2023 Tesla Model Y unexpectedly locked with my [XXX] infant inside during approximately 100°F weather. I briefly exited the vehicle while charging to disconnect the charging cable. My authenticated phone key remained inside the cabin. Immediately after unplugging the charger, the vehicle activated Walk-Away Door Lock and locked all doors despite the phone key remaining inside the vehicle. I was locked out without access to my phone and had to ask a stranger to call 911 and contact my husband. Cabin temperatures rapidly became dangerous for an infant. My husband was eventually able to remotely unlock the vehicle using the Tesla app, narrowly avoiding forced entry by emergency responders. The vehicle failed to detect the phone key inside the cabin and improperly initiated locking while a vulnerable child occupant was present. This created a serious risk of heat injury or death. The vehicle also failed to prevent the lockout despite an infant occupant being seated in the second row, raising concerns about whether rear-seat occupancy detection and child safety protections functioned properly during the event. I am requesting investigation into Tesla’s proximity sensing, phone key detection, walk-away lock behavior, and child occupant safety protections during charging/unplugging events.

| May 2026 | BACK OVER PREVENTION | While reversing my Tesla Model Y, the rear parking sensors failed to alert me to a stationary obstacle (fence). No audible warning or visual alert was triggered. The vehicle had recently received a software update prior to the incident. The failure resulted in collision damage to the rear bumper. I believe this may be a sensor or software defect. I am requesting an investigation into whether recent OTA updates affected rear obstacle detection functionality. | Crash: Yes Fire: No | Unknown |
| May 2026 | SUSPENSION | I was driving in Topanga Canyon, heard a loud clang. Noticed the steering was off, so pulled over. The front lateral links had failed and it took me 6 hours to get a tow. Had I been at freeway speeds when that happened, I may have crashed and not been able to pull over safely as I was headed towards the 101 freeway before the links failed. Upon researching this, I found online this is a common issue with Tesla’s. If I need it don’t again, I don’t want to have to pay for an issue that’s a manufacturers defect. | Crash: No Fire: No | Unknown |
| May 2026 | FORWARD COLLISION AVOIDANCE | Recurring camera and Autopilot defect on a 2023 Tesla Model Y (HW3 with in-cabin camera, in scope for NHTSA Recall 23V838). 7 service visits in 13.5 months and ~14,000 miles of my ownership. Tesla verified the camera/Autopilot defect in writing on 12/5/2025 and replaced the upper Quad Camera Cover (P/N 1755687-00-B) and Interior Camera (P/N 1588124-S0-I). Same defect returned by 4/27/2026. On 4/28/2026 Tesla service issued a Could Not Duplicate citing 'no log data showing signs of autosteer having an issue or any camera blocked alerts.' But Tesla's own VIN-linked telemetry, which Tesla provided me via Privacy Portal data request, contains: 28 Autopilot FAULT events on 14 of 27 retained days; 1 ABORTING event matching my report to the minute; and 17 highway-speed (>=50 mph) phantom-brake-class hard decelerations <= -0.20 g. The worst event: 4/28/2026 at 2:12 PM EDT, less than 90 minutes after Tesla returned the vehicle. Autopilot was in ACTIVE_NOMINAL state with cruise engaged at 63.6 mph. System produced an unprompted -0.252 g (-2.47 m/s^2) deceleration. Driver was not braking; system was driving. Additional phantom brakes: -0.297 g at 62.9 mph on 5/2/2026; -0.294 g at 70.0 mph on 5/3/2026. Multiple Take Over Immediately alerts without explanation. Camera Blocked alerts in clear conditions. Driver-monitoring system flagged 'hands NOT detected' on 339 of 684 monitoring detection events during the 27-day window despite hands being on the wheel — the recall remedy mechanism is failing on this vehicle. This vehicle is in scope for NHTSA Recall Query RQ24009 (open), investigating whether the 23V838 OTA remedy actually fixed the underlying Autosteer defect. My data is direct fleet-level evidence the remedy did not work on this VIN. Currently in active New Vehicle Limited Warranty. | Crash: No Fire: No | Unknown |
| May 2026 | EXTERIOR LIGHTING | While using Full Self-Driving on my 2023 Tesla Model Y, the automatic high beams repeatedly activate in active traffic conditions, including when following other vehicles and when oncoming traffic is present. The system does not consistently dim the lights, creating glare that could impair visibility for other drivers. The driver is unable to permanently disable automatic high beams while FSD is engaged. | Crash: No Fire: No | Unknown |
| May 2026 | VEHICLE SPEED CONTROL,LANE DEPARTURE | 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. | Crash: No Fire: No | Unknown |
| May 2026 | POWER TRAIN,ELECTRICAL SYSTEM,ENGINE | While driving on I-95 North in the fast lane at highway speed, my 2023 Tesla Model Y experienced a sudden loss of propulsion and displayed a warning indicating the vehicle was shutting down. The vehicle rapidly decelerated and would not respond to acceleration or drive engagement. Steering remained functional, which allowed me to maneuver the vehicle across lanes to the shoulder to avoid a potential collision. This required an emergency maneuver in active highway traffic with my family in the vehicle. A soft reset did not resolve the issue. After performing a hard reset, I was able to move the vehicle slowly off the roadway to a nearby location where it was later towed. This incident occurred without prior warning and created a significant safety hazard due to sudden loss of propulsion at highway speed. | Crash: No Fire: No | Unknown |
| Apr 2026 | VISIBILITY/WIPER | Washer fluid indicated low washer fluid. Refilled washer fluid, but shortly after washer fluid leaked out underneath the vehicle. Took the vehicle in for repair at an Tesla Service Center and service advisor indicated that the reservoir had cracked at the seam (an obvious defect of the reservoir). They stated it was not considered a defect even though it was obvious the crack was at the seam. Given the age of the vehicle and the fact that the vehicle is constantly garaged when parked this seems to be an abnormal issue. Had I not taken this in to get serviced there could have been an issue with not having any washer fluid in the reservoir when needing to clean the windshield which would pose a visibility hazard and could potentially lead to a collision. | Crash: No Fire: No | Unknown |
| Apr 2026 | ELECTRICAL SYSTEM,VEHICLE SPEED CONTROL,FORWARD COLLISION AVOIDANCE | ### 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. | Crash: No Fire: No | Unknown |
