NHTSA received a petition from Edward Chen “to initiate a Defect Investigation into the recent set of software updates, including software updates 2019.16.1 and 2019.16.2 and all subsequent updates issued by Tesla, Inc. to its Model S and Model X vehicles, which have been alleged to be issued by Tesla in response to the alarming number of car fires that haveoccured worldwide.”

Chen is an attorney representing a plaintiff is a class action lawsuit related to the software updates.

NHTSA is requesting information from Tesla related to the petition.

As MaxedOutMama noted on Seeking Alpha:

'They want everything, and they want it by Nov 28th. A list of all cars made for sale or lease in the US, all complaints, all actions, all arbitrations, etc, the internal docs relating to those.
They also want to have all updates that affected the BMS listed and described, with reasoning, owner disclosures, etc. Item 6 is a request for all internal studies, surveys, data etc related to charging history's effect on battery health, shorting conditions, fires, etc,
It is a genuine, serious and comprehensive investigation.
The noose tightens, and one suspects that this sort of activity will tend to spread across the pond.'
