Ford Motor Co reported an 11.7 percent fall in October vehicle sales in the United States, led by a decline in sales of cars such as the Mustang and Ford Fusion sedan.

October vehicle sales in the United States fell to 188,813 from 213,938 a year earlier, Ford said on Wednesday.

The No. 2 U.S. automaker’s October sales fell below the estimate of 208,259, according to Autodata Corp, an industry body that tracks new vehicle deliveries.

Detroit-based Ford is reporting sales a day later than the rest of the industry due to a fire on Monday at its headquarters, which interrupted power to a data center that the company and its dealers use to report and track sales.

Overall U.S. auto sales fell an estimated 4.4 percent to 1,392,786 vehicles in October, Autodata reported on Tuesday. The monthly data included the estimates of Ford’s sales.
