The issue is that this investigation is important to Tesla but not considered 'Major' in NTSB definition. In a major investigations, such as airline crashes, the NTSB are the lead agency who give press multiple press conferences and release preliminary information to the media.

It is considered very bad form for any designated parties[0] participating to talk to the media other than with NTSB approval. Non-essential organizations like union representatives have been booted from investigations for talking to the media.
