NHTSA Complaint #11450499 — 2021 TESLA MODEL Y

When using AutoPilot, the car will without any basis or immediate need brake most abruptly without any due cause, as there is no traffic or cars around it. It’s usually when passing over overpasses but not always. This sudden deceleration has almost caused accidents. Only me being wary and cognizant has saved the car from being rear ended. Sometimes there’s no cars around but it still can be very dangerous. This has been happening over almost a year and Tesla has not done anything to address this widespread issue.
