NHTSA Complaint #11706163 — 2026 TESLA MODEL Y

Tesla self driving detects and sets a speed limit and displays it as a speed limit icon. I used self driving to exit my driveway, which turns onto a dirt road with a speed limit of 15 MPH. Near the bottom of the driveway self driving suddenly reset the speed limit from 10 MPH to 55 MPH. The car then accelerated abruptly shortly before the turn onto the dirt road. There is no mechanism for overriding the speed limit the Tesla self driving automatically selects. It is clear that the speed of the vehicle is adjusted according to the speed limit that Tesla self driving selects. Before I could regain control of the vehicle I was almost into the field opposite the driveway. The inability to re-set the automatically selected speed limit is dangerous. The speed limit has spontaneously reset to 55 MPH on two other occasions, and the vehicle spontaneously speeded up.
