General Motors will cut production at most North American assembly plants this month because of the ongoing semiconductor chip shortage, hitting its profitable truck and sport utility vehicles.

The automaker told Reuters it would halt production next week at its Fort Wayne plant in Indiana and its Silao plant in Mexico, both of which build pickup trucks. GM is cutting production at eight North American assembly plants in September.

GM would halt production at its Wentzville, Missouri plant, which builds midsize trucks and full-size vans, for two weeks starting 6 September, Reuters said.

GM would also halt production at the CAMI Assembly in Canada and San Luis Potosi Assembly in Mexico for two additional weeks. The company builds the Equinox SUV at both plants.

The automaker is also idling production for two additional weeks at its Lansing Delta Township plant that builds the Chevrolet Traverse and the Buick Enclave.

GM’s Spring Hill Tennessee plant, which builds the GMC Acadia, Cadillac XT5 and Cadillac XT6, will cut two weeks of production in September, the report said, while its Ramos, Mexico plant will take two additional weeks of downtime for Blazer production and Equinox production will be down for the week of 27 September.

Production of the Equinox has been down since 16 August, Reuters noted.

GM said during production downtime it will complete and ship unfinished vehicles from many impacted plants, including Fort Wayne and Silao.
