This is the best summary I could come up with:

The US Department of Justice (DOJ) is investigating the range of Tesla’s electric vehicles after reports surfaced that the company was relying on exaggerated numbers.

In documents filed with the Securities and Exchange Commission, Tesla said that it had “received requests for information, including subpoenas from the DOJ, regarding certain matters associated with personal benefits, related parties, vehicle range and personnel decisions.”

Earlier this year, Reuters reported that Tesla had received so many customer complaints about range that it created a special “diversion team” to cancel their service appointments.

Customers were incensed that their Tesla vehicles were falling well short of the advertised range, sometimes by as much as half the number of miles that they were purported to get on a full charge.

Rather, Tesla had allegedly created software to rig its driving range estimates to show a rosier picture.

A year later, the company had to pay thousands of dollars each to customers in Norway for allegedly throttling its battery charging speed.
