NHTSA Complaint #11631709 — 2020 TESLA MODEL S

Since the installation of software version 2024.27.25, which includes FSD version 12.5.4, on Sept 26, 2024, any driving which occurs on FSD results in emergency braking events for Green Lights, unprotected/unsignaled crosswalks without pedestrians present, Parallel Parked Cars not encroaching on the lane of travel, vehicles traveling the same direction and similar speed (+/- 5mph), not encroaching on my lane. These frequently reoccurring events were not remedied by any of the subsequent updates received: v2024.32.10 (FSD v12.5.4.1) on Oct 8, 2024 v2024.33.5 (FSD v12.5.4.2) on Nov 2, 2024 2024.44.25.2 (FSD v12.5.4.2) on Dec 10, 2024 While not all events occurred with surrounding traffic, those that did posed a hazard to not just occupants of my vehicle, but those in and around other vehicles, including pedestrians. Most other drivers do not expect and are unprepared for a vehicle to apply panic-level emergency braking and come to full stop at green lights, before unprotected crosswalks with no pedestrians present, or along well-traveled streets without significant errant other drivers. No warning lights, chimes, or other indications ever appeared on any of the displays or instrument clusters within the vehicle during any of the events. The FSD traffic display did not indicate or highlight any features of the surrounding area that were causing it to slow or stop. The problem has been regularly experienced by many other drivers, as evidenced by the large number of similar reports across the various Tesla driver communities online. I and my vehicle are available for inspection and I'm additionally willing to take an inspector on a ride-along to demonstrate the issue.
