I am filing a formal safety complaint regarding a severe braking and stability control failure that resulted in unpredictable, highly dangerous vehicle behavior. While driving, the vehicle displayed a cascade of critical system failures, throwing error codes APP_w009 (AEB disabled), DI_a222 (Stability control disabled), DI_a223 (Traction control disabled), ESP_a080, and ESP_a067 (ESP/ABS sensor faults). This concurrent breakdown caused a total loss of critical safety features: Anti-lock Braking (ABS), Automatic Emergency Braking, Traction Control, "Vehicle Hold," and "Hill Start Assist." Because the vehicle completely lost its ability to hold its position, it unexpectedly free-rolled backward on an incline when I anticipated it to remain stationary or move forward. This uncommanded movement created an immediate collision hazard. Of serious concern is that despite a total breakdown of vital braking and stability assists, the vehicle remained fully drivable and only advised me to "drive with caution." Allowing a car to remain operational under these severe fault conditions is an unacceptable risk. A driver expecting normal EV behavior (like vehicle hold and regenerative braking) is placed in immediate danger when the vehicle suddenly free-rolls without warning. The software should classify a multi-system ABS/ESP failure as a critical emergency requiring an immediate safe shutdown, rather than suggesting it is safe to continue driving.

While out on vacation in [XXX] on XXX at around 11 am I had just finished charging the Tesla at a supercharging station. I was headed to go eat breakfast at the intersection of [XXX] and XXX on the right lane. I stopped briefly prior to making a right onto [XXX]. Upon making the right turn the vehicle kept turning all the way right and making a sharp right turn instead of a soft right. When I noticed the sharp right turn I tried to turn the steering wheel towards the left but the steering wheel was locked and it wouldn't respond. The car drove me into a concrete barricade and caused a collision. My children were in the car and thankfully no one in my vehicle was seriously injured nor were there any pedestrians on the sidewalk near the barricade. I contacted Tesla for the repair and investigation into why the steering wheel locked. Tesla has not provided a loaner vehicle in the meantime despite my frequent requests. This incident is a serious and critical safety issue that may have caused deaths had I been traveling at a higher rate of speed or been on the highway heading back to [XXX]. The strange thing is that this vehicle is still under warranty with Tesla and had been working just fine without any issues since I got the vehicle in XXX. No warning messages, or symptoms to indicate any malfunction. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I am reporting a safety incident involving my 2025 Tesla Model Y and Full Self-Driving. While driving with Full Self-Driving engaged… latest update, the vehicle steered into an express-lane barrier/bar structure. The impact caused severe windshield damage and apparent body damage near the passenger-side A-pillar / windshield frame / roof rail area. The windshield is heavily cracked across the driver’s side and center area, and the vehicle is not safe to drive. I was able to get home safely and filed an insurance claim. I preserved TeslaCam footage and photos of the damage. The in-vehicle Tesla playback shows Full Self-Driving engaged during the incident. I also copied the TeslaCam files from the vehicle’s USB drive. The exported video file does not appear to show the same Full Self-Driving overlay that appears in the in-vehicle playback. I am reporting this as a potential safety issue involving Tesla Full Self-Driving steering behavior and impact with a fixed roadway/express-lane structure. No injuries occurred, but the vehicle sustained significant windshield damage and possible body/frame-area damage.

The persistent intervention-reason prompt (the black box that appears immediately after disengaging FSD and stays until answered) creates a safety-critical distraction exactly when the driver must regain full attention and control. It forces eyes off the road or interaction with the screen during the handover moment, increasing crash risk. It cannot be dismissed without input and has no timeout or “X” button. Request NHTSA investigate this as a potential defect in the driver-assistance system.

On May 24, 2026, at approximately 8:28 AM, I activated Actually Smart Summon on my 2025 Tesla Model 3 using the Tesla mobile application to reverse the vehicle from my garage. Before this incident, the vehicle displayed no warnings, alerts, messages, or other indication of a problem, and I had previously usd Actually Smart Summon without similar behavior. Shortly after activation, the Tesla mobile application became unresponsive, and the vehicle did not stop despite my attempts to stop it through the app. I attempted to open the vehicle door during the incident but was unable to do so while the maneuver continued. Because I could no longer stop the vehicle through the app or access the vehicle, I placed my phone in my pocket so I could use both hands to try to stop the vehicle and prevent further damage. At that point, I was no longer pressing or holding the Actually Smart Summon control in the application. As the vehicle continued reversing, I repeatedly repositioned myself behind it and pushed against the rear of the vehicle with my body multiple times. Despite this physical intervention, the vehicle continued reversing and applying rearward force, forcing me to repeatedly move out of its path to avoid being pinned between the vehicle and my neighbor s garage. The vehicle pressed into my neighbor s garage with enough force that the impact transferred to the parked vehicle inside the garage. It did not stop upon the initial impact and continued pressing into the garage afterward. This sustained movement is clearly visible on the preserved TeslaCam footage and independent home-security recordings. I narrowly escaped being crushed between the vehicle and the garage while attempting to stop the vehicle and prevent further damage, sustaining a muscle strain in the process. The incident created a serious risk of bodily injury in addition to substantial property damage. I do not know which specific component or system failed. Based on the sequence of events, the incident
