Tesla said on Tuesday it was recalling most Cybertrucks in the United States over issues with their windshield wipers and exterior trim, the latest setback for the futuristic truck whose mass production is expected to start next year.

This physical recall of vehicles, not rare for new models, is relatively unusual for Tesla, whose problems are usually resolved through over-the-air software updates.

The Cybertruck is Tesla CEO Elon Musk’s answer to critics who say the company needs to refresh its aging lineup as EV demand has flagged. The electric vehicle maker has been slow to bring new models to market as high interest rates have squeezed consumer appetite and rivals in China have rolled out cheaper models.

The recalls both cover more than 11,000 vehicles. Tesla is yet to disclose how many it has handed over to consumers in its quarterly deliveries and production report.
