Springfield, Ohio plants are affected driven by soft demand for diesel-powered commercial vehicles, but consumer Silverado pickups (1500/2500/3500) remain unaffected. Some reports indicate broader Express/Savana Cutaway variants may be impacted, GM has not detailed replacements for the medium-duty lineup.
