LANSING, MI—General Motors will shut down its Delta Township plant for 11 weeks over the course of 2022 to get ready to build a new vehicle, the GMC Acadia SUV. GM is dedicating $100 million to the changes at the Delta plant, and by the new year workers will see those plans come to life.

The downtime will not be all at once. The first shutdown will last from Dec. 27 to Jan. 17. The rest of the days have yet to be announced.

The new series of shut downs are not related to the ongoing chip shortage, which has halted production at automotive assembly plants throughout the country off and on all year.
