Watch The Tesla Model S Cause That 8-Car Thanksgiving Pileup

By the end of 2022, the FSD feature had been rolled out to over 285,000 vehicles, making it easy to understand why the National Highway Traffic Safety Administration (NHTSA) is concerned and launched a full investigation. On top of this incident, over 100 complaints of “surge” or “phantom” braking by Tesla vehicles have been lodged with the government safety agency.

“The resources require a lot of technical expertise, actually some legal novelty and so we’re moving as quickly as we can, but we also want to be careful and make sure we have all the information we need,” Ann Carlson, the acting head of the agency, told Reuters.
