Affected by the shortage of global automotive chip supply, General Motors extended the production cut schedule of three plants in North America on Wednesday, local time, and included the fourth plant in the ranks of production cuts.

Reuters reported that the expansion of production cuts did not change GM's forecast last month that "this year's profits may be reduced by $2 billion". Paul Jacobson, chief financial officer of General Motors, said that chip supply may return to normal levels in the second half of this year, so the loss of profit will not worsen.

General Motors said it will extend the production cuts at the Fairfax plant in Kansas and the Ingersoll plant in Ontario, Canada to mid-April, and the St. Louis Potosí plant in Mexico to the end of March. In addition, the Gravatai plant in Sao Paulo, Brazil will also cut production in April or May.

In addition, GM spokesperson David Barnas pointed out that the company will continue to use all available chips to make GM’s most popular and most in-demand products, including full-size trucks and SUV models.

It is reported that AutoForecast Solutions, a market research agency, predicts that GM's global auto production may be reduced by more than 216,000 due to supply shortages.
