2023 Tesla Model Y: sudden unintended acceleration

Filed Jun 9, 2026 · Acceleration, Brakes · FL · crash

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.

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 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)

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.

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.

I was operating my 2023 Tesla Model Y Long Range AWD with Full Self-Driving (FSD) engaged at low speed in a residential neighborhood. The vehicle took an incorrect turn into a neighboring driveway instead of continuing on the roadway. I attempted to correct the vehicle’s path. At that point, the vehicle unexpectedly accelerated. I experienced a sudden loss of control and was unable to stop the vehicle before it struck my garage door and entered the garage, causing structural damage to the garage wall. Notably, automatic emergency braking did not activate, and no effective front collision warning intervened, despite an imminent collision with a fixed structure. Tesla’s post-incident vehicle report states that accelerator pedal input was detected, which I believe occurred as a panic response while attempting to regain control after the vehicle took the incorrect turn. However, I am concerned that the vehicle’s software behavior, lack of braking intervention, and failure of safety systems contributed to the incident. This incident raises safety concerns regarding unintended acceleration behavior, FSD path selection errors at low speed, and failure of emergency braking or collision avoidance systems when approaching fixed objects such as garage doors or walls.

While operating my Tesla Model Y in a commercial parking lot at a T-intersection controlled by a stop sign, the vehicle unexpectedly and automatically accelerated without driver intent. The incident occurred during a low-speed maneuver. Upon the unexpected acceleration, I immediately attempted to regain control by applying the brake pedal repeatedly and firmly. Despite clear manual brake application, the vehicle did not decelerate as expected and continued to move forward. I also attempted to stop the vehicle by pressing the Park button, but this action did not stop the vehicle. The vehicle continued uncontrollably for approximately 150+ yards, traveling over curbs, striking a fence, and ultimately colliding with the garage structure of a residential home. Throughout this sequence, the vehicle remained unresponsive to braking and stop inputs. Vehicle data later confirmed that brake pedal application was detected prior to impact, yet braking response was insufficient to prevent continued motion. At the time of the event, the vehicle recorded system fault states, and collision avoidance systems did not activate. Despite significant structural impact and property damage, airbags did not deploy. The incident raises serious safety concerns regarding: •Brake-by-wire system execution during fault conditions •Pedal input arbitration between accelerator and brake •Failure of collision avoidance systems to intervene •Failure of restraint systems to deploy during a severe impact •Vehicle behavior when control systems are in a fault state This event occurred without warning and despite appropriate driver response. Based on vehicle data and system behavior, this appears to be a system-level failure rather than driver error.

Twice it happened that I felt sudden unintended acceleration twice this week. Last one happened last night on my way to work and the experience is frightening that I had to drive very slow with my feet ready for the brakes in case it happened again.

Date of incident 9/9/24 11:15 AM 2023 Tesla Model Y traveling north bound I-15 using Tesla Autopilot intending soon to exit Pioneer Crossing / American Fork UT in the far right lane — vehicle made sudden move to right glancing off wall causing scraping damage to right front quarter panel, and hub cap. Although I stepped on the brake in attempt to take control of the vehicle I immediately experienced uncontrolled acceleration and difficulting in steering. I chose not to exit and fought to keep the vehicle in varying freeway lanes attempting to brake to which the vehicle continued to attempt to accelerate against the braking, I also simultaneously and frantically continued to push the right stalk upwards in attempt to disengage Autopilot assuming that was causing the unintended acceleration. I was fighting to keep the car in a lane with faulty steering at time awakwardly steering to avoid slower moving vehicles. I eventually ended up coming to a complete stop in the middle lane of I-15 north bound 9/10ths (nine tenths) of mile north of my intended exit (mile post #278 Pioneer Crossing). Because of faulty controls I was afraid to try to move the vehicle to the side — I immediately put on emergency flashing lights and called 911 on my cell phone. While nervously waiting for emergency services approaching vehicles slowed and made their way around me — per instruction I stayed in my vehicle with seatbelt on. One large pickup truck struck my vehicle driverside rear as he passed by and failed to stop. Utah Highway Patrol and Fire Department Ambulance arrived within approximatley ten minutes. Two highway patrol officers stopped traffic and assisted in me slowing driving my vehicle to the center emergency lane. One office stayed with me until tow. He commented the right rear wheel appeared not aligned correctly suggested the rear axle was possibly broken. I was not injured beyond being extremely frightened. No passengers.
