Aug. 8, 2019—Tesla stood behind its Model 3 safety claims on Wednesday, while documents showed the top U.S. automotive safety watchdog issued at least five subpoenas since last year seeking information about the crashes with the company's cars, according to a report by Reuters.

Tesla has said the Model 3 “was engineered to be the safest car ever built” with the lowest probability of injury of all vehicles ever tested by the National Highway Traffic Safety Administration (NHTSA).

Asked for comment by Reuters on Wednesday, Tesla pointed to its response to the October letter, in which it said its claims were based on NHTSA’s own data.
