Japanese automaker Toyota outsold General Motors in the US in 2021, marking the first time the Detroit automaker has not led US car sales for a full year since 1931.
Toyota sold 2.332 million vehicles in the US in 2021, compared with 2.218 million for General Motors, the automakers said.
GM's US sales were down 13% for 2021 - and down 43% in the fourth quarter - while Toyota was up 10% for the year. GM last had lower sales in 2010 at 2.202 million.
For all of 2020, GM's US sales totaled 2.55 million, compared with Toyota's 2.11 million and Ford's 2.04 million.
Last year was marred by a shortage of semiconductors used heavily in vehicles, forcing car makers to focus on their most profitable models.
GM said it expects US economic growth will boost total light-duty vehicle industry sales from around 15 million in 2021 to around 16 million in 2022.
GM has been the largest seller of vehicles in the US since 1931, when it surpassed Ford, according to data from industry publication Automotive News.
Toyota is not boasting about the accomplishment. Senior Vice President Jack Hollis said the automaker is "grateful" for its loyal customers, but "being number one is never a focus or priority."
The Japanese automaker does not see its US gains as sustainable and had no plans to use the 2021 accomplishment in any kind of advertising, he added.
Toyota had been credited by analysts for weathering the chip shortage better than other automakers.
GM spokesman Jim Cain said the Detroit automaker had a very strong sales year in the US in full-size SUVs and pickup trucks as it has focused on profitability, and as the supply of semiconductors improves, so will sales.
GM under Chief Executive Mary Barra also has emphasised profitability over volume, abandoning such money-losing markets as Europe and Russia.

For the entire industry, sales finished 2021 at just under 15 million vehicles, according to Wards Intelligence, with the annual sales rate in the month of December finishing at 12.44 million.
The full-year number was well below the five-year average of 17.3 million from 2015-2019.
IHS Markit forecasts US sales are expected to reach nearly 15.5 million in 2022.
Toyota sees industry sales jumping to 16.5 million this year, with demand even higher if the industry can boost production further, with its own sales topping 2.4 million.
