Pre-facelift Model X production in December 2020 helped prepare for the official January 2021 unveiling of

the facelifted Tesla Model X and Model S. Elon Musk has acknowledged that they "dropped the ball badly" on

the Model X's manufacturing as a result of the regrettable delay in the facelifted model's release to customers—

October 2021. Tesla investor Sawyer Merritt sparked Musk's remarks on Twitter, claiming that the updated

Model X rollout was a total disaster, made worse by a lack of communication with customers who had been

waiting for their cars for a year or longer.
