Tesla’s claims about the safety of its Model 3 electric vehicle prompted U.S. regulators to send a cease-and-desist letter and escalate the matter by asking the Federal Trade Commission to investigate, according to documents released by the nonprofit legal transparency website PlainSite.

The documents show correspondence between the lawyers at National Highway Traffic Safety Administration and Tesla that began after the automaker’s October 7 blog post that said the Model 3 had achieved the lowest probability of injury of any vehicle the agency ever tested. PlainSite received the 79 pages of communications since January 2018 between NHTSA and Tesla through a Freedom of Information Act request. There were 450 pages of communication that were withheld due to Tesla’s request for confidentiality on the basis of “trade secrets.”
