Nikon USA has announced the temporarily suspension of all equipment repair services due to the spread of COVID-19. The decision was made in compliance with federal guidelines, and in the interest of protecting employees' health and safety.
Nikon is shutting down its authorized repair program at the end of March, 2020. According to an email sent to authorized repair shops, and confirmed by Nikon Inc. (see update), Nikon users in the United States will soon have to rely exclusively on Nikon itself for any repairs that require special parts, tools, or training—that is: almost all repairs.
A year ago, Nikon caused a big stir when the company stopped making repair parts available to independent repair shops. As a result, getting your Nikon fixed became more expensive and cumbersome, requiring you to send it out to an "authorized repair facility" or get your parts second-hand off eBay.
The good news is that now, in a half-hearted step back, Nikon has started selling select (read: extremely limited) repair parts direct to consumers online through the Nikon Parts Store.
