NHTSA Complaint #11636606 — 2021 TESLA MODEL Y

Since March 2024, FSD has failed to function as designed. Tesla denied any problem with the vehicle until October 2024, when a manager told me it's a known issue with no available fix. The issue started with FSD not recognizing traffic signals. Meaning that regardless of whether a traffic light was green or red, the vehicle would treat it like an 4 way stop. It would come to a stop and then proceed through the intersection if it didn't detect immediate cars. This was dangerous and Tesla refused to acknowledge the problem for months. Since then the issue has evolved with FSD only engaging in certain situations (interstate driving). As of the most recent update, FSD won't engage at all.
