A Tesla spokesperson told Reuters last week that the company had received a voluntary request from the Department of Justice for documents related to Model 3 production forecasts, but had not received a subpoena.
When the Model 3 was launched in 2017, the company was optimistic about quickly ramping up production of the highly anticipated model.
Musk, 47, also called the vehicle business "monumentally difficult" and repeated a point he's made in the past - that Tesla and Ford were the only US automakers to stay out of bankruptcy during the last recession.

The Elon Musk-led company said in a filing Friday that thus far, no government agency in ongoing investigations has concluded that any wrongdoing occurred. It didn't hit the 5,000-a-week target until June 2018.
Today's news follows on from recent reports in the Wall Street Journey that suggested Federal Bureau of Investigation agents were looking into whether or not Tesla misled investors about production of its Model 3 cars.
