General Motors is extending downtime on vehicle production shifts for three assembly plants in North America due to the ongoing automotive semiconductor shortages, according to the automaker.

The automaker said it is extending downtime at its San Luis Potosi plant in Mexico through the end of March. GM said it would also extend downtime at its Fairfax plant based in Kansas and its CAMI plant in Canada to at least mid-April, GM said.

“GM continues to leverage every available semiconductor to build and ship our most popular and in-demand products, including full-size trucks and SUVs for our customers. GM has not taken downtime or reduced shifts at any of its truck plants due to the shortage. We continue to work closely with our supply base to find solutions for our suppliers’ semiconductor requirements and to mitigate impacts on GM,” the automaker announced.

The Fairfax assembly plant produces the Cadillac XT4 and Chevrolet Malibu; the San Luis Potosi plant manufacturers the Chevrolet Equinox, Chevrolet Trax, and GMC Terrain; and the CAMI plant also produces the Chevrolet Equinox.

GM said it’s intent is to make up as much production lost at these plants as possible.
