Owner reports
Selected complaints filed with NHTSA by 2026 Tesla Model Y owners, lightly cleaned up (personal details are redacted by NHTSA).
The contact owns a 2026 Tesla Model Y. The contact stated that while driving at an undisclosed speed with the Full Self Driving Mode activated, the vehicle struck the garage wall, damaging the rear passenger's side door. No injuries were sustained. The contact stated that the dealer had previously provided mobile service to replace the camera and that a second dealer, Tesla White Plains (250 Tarrytown Rd, White Plains, NY 10607), had performed a hard reset on the vehicle due to phantom braking; however, the failure persisted. The dealer was made aware of the failure but canceled an upcoming appointment and informed the contact that there was no failure found. The vehicle was not diagnosed or repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 13,001.
On November 4, 2025, I believe my New Tesla (only 2 month old) had just updated to a new software version. That morning, when I tried to start the car to drive to Walgreens Pharmacy, the vehicle did not start - the screen was locked. I pressed the brake pedal several times, but there was no response. Then I pressed the accelerator and the brake again, and the car finally started. I believe i turned on the Full Self-Driving (FSD) mode as usual. The car backed out of my garage and moved only about ten houses down our street when I suddenly felt it was out of control, and within seconds, it hit a stationary vehicle on our street. I did not hear Forward Collision Warning or feel the Automatic Braking system engage. The tesla report told me that the collision warning failure and the Safety systems are affected, and the passage side (front right) tire shows 0 psi) . …
On the day of the incident, I drove my vehicle into the charging station and activated the Tesla FSD autonomous driving and automatic parking functions. During the automatic parking attempt by the vehicle, the system exhibited the following severe loss of control behaviors: 1. The vehicle automatically collided with the vehicle in front without any human operation. 2. It paused for about 1 second after the collision. 3. Then, the vehicle suddenly accelerated in reverse at high speed, again without any driver operation. 4. It directly hit another Tesla that was charging behind my vehicle. The entire process is fully executed automatically by the vehicle system. I cannot intervene or stop the system through the steering wheel or brakes. II. Severe Security Risks When the accident happened, my friend was sitting in the passenger seat. …
At approximately 5:50 PM on Feb 12, 2026, a collision occurred while the vehicle was under the control of "Full Self-Driving (Supervised)." While parked in a commercial lot, I engaged FSD to initiate a route home. A stationary semi-truck was positioned behind my vehicle. Upon engagement, the FSD system failed to detect the presence of the stationary truck. The vehicle initiated a rearward/lateral maneuver at a speed of 1 mph, directly striking the corner of the semi-truck. Safety Failure Details: The collision resulted in significant damage to the right rear quarter panel and associated sensors of my Tesla Model Y. Dashcam footage and system telemetry confirm that FSD was active (Supervised mode) during the entire duration of the maneuver. The system's occupancy network and vision suite failed to identify a large, stationary object within its immediate path of travel at a crawl speed. …
On June 7, 2026, while Full Self-Driving (FSD) was engaged, my 2025 Tesla Model Y drove itself forward out of a parking spot and struck a stationary landscape rock directly in its path. The vehicle did not slow, brake, or steer to avoid the obstacle before impact. The rock was a fixed object roughly 20 inches tall, clearly visible in the vehicle's forward (windshield) camera from a complete standstill, before FSD began moving the car. It stayed visible as the car advanced and dropped into the camera's near-field blind zone just before contact. The vehicle struck it with no apparent detection or avoidance. This is a serious safety concern beyond the resulting property damage. An obstacle of this height is in the same range as a small child or a crouching person. …
The vehicle made contact with other vehicles twice within a short period while Full Self-Driving (Supervised) was engaged, and it did not respond to my attempts to intervene. On [redacted], at approximately 1:30 PM, in the Stanford Oval parking area in [redacted], I was using Tesla Full Self-Driving (Supervised) in my brand-new 2026 Tesla Model Y when the vehicle began a reversing maneuver between two parked vehicles. During the maneuver, the on-screen visualization continued to show space between my vehicle and the surrounding vehicles. The vehicle then made physical contact with another vehicle. I received no proximity or collision alert, and the display continued to show clearance after contact occurred. After contact, the vehicle continued attempting to reverse, stalled, and behaved erratically. …
On the highway, a vehicle in the lane next to me on the right moved towards the white dividing line, but never actually crossed into my lane. My Tesla was operating on Full Self-Driving (Supervised). The system miscalculated the front vehicle's trajectory and severely overreacted to it approaching the line. Without driver input, the FSD system initiated sudden, heavy braking and violently swerved to the left, crossing the lane line. Because the Tesla swerved suddenly into the left lane, the driver already occupying that lane was unable to avoid a collision, striking the left rear corner of my vehicle. I have video recordings from my Tesla that provides objective proof that the vehicle in front did not sideswipe or cut off my car, but rather that an abrupt vehicle automation failure forced my car out of its lane, I had no chance to react quick enough to avoid the accident. …
On August 15, 2026, at approximately 5:00 PM, the vehicle was being driven with Full Self-Driving (Supervised) engaged during light rain. As the vehicle approached traffic ahead, it did not slow or brake as expected. The driver recognized that the vehicle was not slowing and attempted to intervene manually by pressing the brake pedal multiple times. The driver reports that despite these attempts, the vehicle did not slow or respond to the brake pedal as expected, and a collision occurred. There were no known warning lamps or warning messages indicating a braking-system problem prior to the incident. The vehicle has not yet been inspected to determine the cause of the reported braking behavior. …
On October 7, 2026, at approximately 1:00 PM, I was driving through a gated entrance. Full Self-Driving (Supervised) was engaged when the vehicle made contact with the entrance gate arm/barrier, resulting in property damage. The apparent safety issue was that, while FSD (Supervised) was controlling the vehicle's movement, the system did not prevent the vehicle from contacting the barrier. Afterward, the vehicle did not display or save the collision as a detected safety event. No one was injured. The incident nevertheless created a safety risk because the vehicle contacted a fixed barrier while the driver-assistance system was engaged. The issue has not yet been inspected or confirmed by Tesla or an independent service center. The vehicle is available for inspection upon request. …
On [redacted] at approximately 3:52 PM, I was reversing my 2026 Tesla Model Y (VIN [redacted]) in the parking lot of the Tesla store/service center in [redacted], while Full Self-Driving (Supervised) was engaged. The vehicle failed to detect a stationary iron pole in the parking space and continued reversing into it, resulting in a collision that scuffed the paint and left a small dent on the rear lower bumper trim. The FSD system gave no warning and did not brake before impact. I have dashcam footage confirming FSD was active at the time of the collision. When I reported the incident to Tesla service staff at the location, they stated the collision was the driver's fault and denied any responsibility of the FSD system. I am concerned that FSD's failure to detect a large stationary metal obstacle at low speed indicates a safety defect in the driver-assistance system.
