The FBI is reviewing Tesla's Model 3 production numbers as part of an ongoing criminal probe into whether the company misled investors, according to a Wall Street Journal report published Friday.

Federal agents are reviewing Tesla's stated Model 3 numbers dating back to early 2017, the Journal reports, citing unnamed sources.

Tesla had previously said it provided documents to the Department of Justice regarding CEO Elon Musk's controversial take-private tweet — a blunder that ultimately cost Tesla and Musk a combined $40 million in fraud settlement fees.

Now Tesla says it also provided information to the Department of Justice regarding Musk's public statements regarding production numbers of its Model 3 sedan.
