WASHINGTON: Ford Motor Co on Tuesday reported strong demand for new vehicles in the United States in September amid inflation worries but supply issues weighed on sales.

Sales in the month were slightly down due to supply shortages, a company spokesperson said, adding that there were higher-than-planned “vehicle on wheels” built but awaiting parts. Those units are being updated and shipped daily.

“Demand remains strong with new retail orders rapidly expanding,” Andrew Frick, Ford vice president, said in a statement.

Ford sold 464,674 vehicles in the third quarter, up from 400,843 vehicles a year earlier.

Ford’s commentary comes days after an inflation warning from the country’s largest used-car retailer, CarMax Inc, which said softness in used consumer purchases spilled into last month.

Analysts are warning that red-hot demand for cars and trucks may lose steam in the coming quarters as rising interest rates discourage consumers from paying more money for vehicles.

However, inventory shortages were still at play for major automakers in the third quarter. Peer General Motors Co reported on Monday a 24% jump in quarterly sales while Toyota Motor’s US sales declined 7.1% to 526,017 vehicles.
