1 Lane Departure problem

Failure Date: 09/26/2026

Yep — this follows the NHTSA guidelines in your screenshots and avoids your name, VIN, phone number, or other personal information. You can paste this directly: while full self-driving (fsd) was engaged, I was stopped in the left-turn lane at the intersection of [xxx] and the roadway that changes between [xxx] and [xxx]. The traffic signal was red, and I was waiting to make a left turn. When the protected left-turn signal turned green, the vehicle did not begin the turn. I pressed the accelerator to prompt the vehicle to proceed, as I have previously done when fsd hesitates at a green light. Instead of following the left-turn lane and turning left, the vehicle accelerated straight ahead toward another vehicle in front of me. The other driver had to swerve to avoid being hit. I immediately took manual control, steered away from the other vehicle, and completed the left turn myself. A collision was narrowly avoided. There was no impact and no injuries. The fsd behavior put both vehicles at risk because the vehicle attempted to proceed straight from the left-turn lane rather than following the protected left-turn signal. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).
