GM announced extended downtime for its Flint Assembly plant, stopping heavy-duty Silverado/Sierra production for four weeks until January 26, 2026, alongside a month-long closure at the Corvette factory in Bowling Green, Kentucky. These stoppages occur amid broader industry turbulence in truck sales, leading to industry speculation about whether the downtime reflects necessary maintenance or deeper inventory adjustments, despite assurances from union reps that layoffs are temporary.
