New York (CNN Business)Fans eager for the return of Ford's full-size Bronco SUV will have to wait a little longer.

Ford had planned to make its first deliveries of the revived Ford Bronco in spring of next year. But the company now says it will be in the summer of 2021

"Our timing is due to Covid-related challenges our suppliers are experiencing," said Ford spokesman Jiyan Cadiz. There are no production problems at Ford's Michigan Assembly Plant, where it is building the Bronco, according to the company.
