It is true that tesla has made all their payments under the doe loan agreement. But they were not in total compliance with said agreement. The agreement required that tesla keep certain financial ratios up to certain levels, and tesla failed to do that. As a result, tesla asked trhe government to change the terms. The government complied but wanted something in exchange. What they wanted was early repayment of their loans. That is why he is talking about early repayment. And that is probably one of the reasons why they raised extra money (although elon is unlikely to admit that).
So that is the full story. It is no big deal, i think tesla are very unlikely to default on the loan, but elon was definately not giving you all relevant info.
