The contact owns a 2023 Tesla Model Y. The contact stated that while pulling into a parking space with the brake pedal depressed, the vehicle unintendedly accelerated and struck an occupied parked vehicle ahead. Upon shifting into Reverse (R), the failure recurred, causing the vehicle to strike the front bumper of a parked and unoccupied USPS truck, which then struck a parked, unoccupied vehicle. The contact engaged the electric parking brake to stop the vehicle. The contact stated that the forward collision avoidance system failed to engage to prevent the collisions. The front driver's side air bag failed to deploy as expected. The vehicle sustained rear-end damage. The vehicle was towed to an auto collision center, where a superficial diagnostic inspection was performed, and the contact was informed that no failure was found. The manufacturer was notified of the failure and referred the contact to a Tesla Service center and to the federal safety agency Hotline for assistance. The failure mileage was 30,616.

Tesla cruise control removed the speed limit functionality as part of its cruise control. I cannot set a maximum speed for the car. Nor can I set a minimum speed for the car. Tesla removed these features through a software update with their autopilot V14. I believe the vehicle is unsafe for myself and others as it does not allow me to set the speed using Traffic-Aware Cruise Control (TACC). Tesla is intentionally removing this feature.

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.

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 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 the federal safety agency engineering analysis.

UPDATE to previous complaint – Reference Number: [XXX] VIN: [XXX]a [XXX] UPDATE to my previous the federal safety agency 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 the federal safety agency 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)

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.

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 the federal safety agency investigate whether this constitutes a safety defect.

### 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.
