General Motors could layoff more than 2,000 workers at two plants, located in Michigan and Ohio.
The move comes after GM reported declining interest in the Chevy Cruze, made in Lordstown Ohio and muscle and sports cars.
The Chevrolet Camaro and Cadillac ATS and CTS Luxury Cars are made at the Lansing Grand River factory in Michigan.
Both the Lansing and Lordstown plants will see third shifts suspended in early 2017.
Workers there could be laid off indefinitely.
Tom Wickham, a spokesman for GM tells WKYC Channel 3's Hilary Golston some employees may be moved to other shifts based on seniority. Contractual obligations with the UAW may determine these shifts.
Wickham says approximately 1,200 will be impacted at the Lordstown location. Another approximately 800 will be impacted at the Lansing location.
While Cruze retail sales have been soft, Wickham says rental and fleet sales have remained steady.
GM also announced it would invest more than $900 million at a Toledo, Ohio, transmission plant, the Lansing Grand River factory and a casting plant in Bedford, Indiana, to prepare for future new vehicles.
