Stellantis' Belvidere Assembly Plant, was indefinitely idled at the end of February 2023. More than 1,000 people were put out of work.

Stellantis will also be upgrading its U.S. auto plants across the country — investing $1.2 billion in the Belvidere plant.

The news, announced in a letter to employees from North America Chief Operating Officer Antonio Filosa on Wednesday, also provided some good news to workers in Detroit, where the next generation Dodge Durango will be built and those in Toledo, Ohio, and Kokomo, Indiana, where investments are planned.
