General Motors will pause production at almost all of its assembly sites throughout North America due to the semiconductor shortage.

Starting Monday, GM will pause production at its Fort Wayne and Silao Assembly plants for a week and expects to restart regular production on September 13. Similarly, the Wentzville Assembly site that handles production of the Chevrolet Colorado, GMC Canyon, Chevrolet Express, and GMC Savana will be offline for two weeks from Monday.

Similarly, the CAMI Assembly plant in Canada and San Luis Potosi sites won’t run until September 27. GM has also added two weeks of extra downtime starting Monday for its Lansing Delta Township Assembly plant. The Spring Hill Assembly site in Tennessee and Ramos Assembly site in Mexico will both take two additional weeks of downtime. The Chevrolet Equinox is built at the Ramos factory and production of it stopped on August 16 and won’t restart until October 4.

General Motors will continue regular production at its Arlington Assembly site in Texas. Full production at its Flint Assembly and Bowling Green Assembly plants will also continue while a portion of the Lansing Green River Assembly site will continue to operate.

“All the announcements we made today are related to the chips shortage, the only plant down that’s not related to that, is Orion Assembly,” GM spokesman Dan Flores told the Detroit Free Press. “COVID is driving supply constraints in countries that produce semiconductor chips. But I can’t say if it’s because employees have a high rate of infection or if it’s the government putting restrictions on plants due to the pandemic.”

Flores added that while production will be halted at the Fort Wayne Assembly and Silao Assembly sites, some activity will still take place at the sites. For example, GM will repair and ship unfinished vehicles in a bid to meet dealer demand for new vehicles.
