NHTSA Complaint #11714968 — 2018 TESLA MODEL X

On 02/01/2026 at approximately 2:07 p.m., my 2018 Tesla Model X (VIN [XXX] , approximately 151,099 miles, software version 2026.2.3) experienced Sudden Unintended Acceleration while I was driving near [XXX] . I was [briefly describe what you were doing, for example: “slowing to a stop in traffic,” or “slowly pulling into a parking space,” or “braking to turn into a driveway”]. My foot was on the brake and I was NOT attempting to accelerate when the vehicle suddenly and unexpectedly surged [forward/backward] with far more power than appropriate for the situation. I had to [firmly press the brake / shift to neutral / steer away] to avoid a collision. At or around the same time, a “Sudden Unintended Acceleration” warning/message appeared on the vehicle’s display. This acceleration did not match my pedal input and created a serious risk of a crash. [There was no contact, damage, or injury / or briefly describe any damage or injuries, if applicable.] The vehicle was operating on software version 2026.2.3 at the time. [Autopilot/Traffic‑Aware Cruise Control/Full Self‑Driving was ON/OFF at the time – please select what is correct.] I have reported this incident to Tesla and requested that they preserve and review the vehicle log data for this time and location. I am filing this complaint because I believe this is a safety‑critical defect involving sudden unintended acceleration, and I am concerned it could recur and/or affect other Tesla vehicles. *** If you tell me exactly what you were doing (parking vs in traffic, approximate speed, forward vs reverse, Autopilot on/off), I can fill in the bracketed parts precisely for you.
