Tesla Inc.’s registrations plummeted in Germany last month as Chief Executive Officer Elon Musk irked voters taking part in the country’s closely contested federal election.

February numbers show the U.S. electric-car maker is struggling to attract buyers in the region. Mr. Musk’s politics aren’t helping.

It appears that Tesla sales are slumping in the U.S., too. According to the California New Car Dealers Association, Tesla registered fewer cars in the state in all four quarters of 2024. California is the largest EV market in the U.S. Tesla sales fell by 8 percent in the fourth quarter and 12 percent for the whole year.
