In Wednesday's earning report, the company's view on the output of those two plants was far more positive.

The German plant "reached an important milestone of over 1,000 cars produced in a single week while achieving positive gross margin during the quarter," the company said. Previously, Tesla had said that June was the highest vehicle production month in Tesla's history.

In comments to investors Wednesday, Musk described the quarter as a "kind of supply chain hell."

"But in spite of all these challenges, it was one of the strongest quarters in our history," he said. Tesla has "the potential for a record-breaking second half of the year," although he cautioned that bullish forecast was "obviously subject to force majeure, things outside of our control."

"The past [few] years have been quite a few force majeures," Musk added.

Tesla has a target to grow global sales by 50% or more annually for the foreseeable future, and at the start of this year Musk said Tesla expected to be "comfortably above" that target in 2022. The company built and sold just under 1 million cars last year, so a 50% increase would represent roughly 1.5 million cars, but ended the second quarter having built and sold about 560,000 cars. Tesla would need to increase production in the second half by more than 75% to reach that 50% growth target for this year.
