General Motors Co. announced plans to shut down three North American full-size pickup truck assembly plants as of August 9 because of the ongoing global semiconductor chip shortage.

The company will idle plants in Flint, Michigan; Fort Wayne, Indiana; and Silao, Mexico, just one week after the plants resumed production after an earlier shutdown related to the shortage.

“The global semiconductor shortage remains complex and very fluid,” GM said in a statement. “The recent scheduling adjustments have been driven by temporary parts shortages caused by semiconductor supply constraints from international markets experiencing COVID-19-related restrictions.”

The GM statement noted that the period will provide the company with an “opportunity to complete unfinished vehicles at the impacted assembly plants and ship those units to dealers.”

The U.S. automaker reported plants in Spring Hill, Tennessee, and Ramos Arizpe, Mexico, will resume production August 9 after being idled since July 19.

GM's Lansing Delta Township plant in Detroit, Michigan, will extend its downtime next week. The company has idled this plant since July 19.

The automaker also extended downtime at its San Luis Potosi, Mexico, and Ingersoll, Canada, plants through the weeks of Aug. 23 and Aug. 30. GM has scheduled those plants to resume production on Aug. 23. Both have been down since July 19.
