General Motors is scaling back production of two of its largest electric vehicles at Factory Zero, its EV-only assembly plant in Hamtramck, Detroit, according to The Detroit Free Press. The automaker will pause both first and second shift production of the GMC Hummer EV and Cadillac Escalade IQ from September 2 to October 6.
“General Motors updates schedules as part of our standard process of aligning production to manage vehicle inventory. Impacted employees will be placed on a temporary layoff and may be eligible for subpay and benefits in accordance with the GM-UAW national contract,” company spokesperson Kevin Kelly said in a statement.
The production halt comes after a similar decision GM made in April at the same Detroit plant. During the earlier pause, the automaker temporarily reduced its workforce by laying off 200 employees amid falling sales of several large electric models, including the GMC Hummer EV (pickup and SUV), GMC Sierra EV, Chevrolet Silverado EV, and Cadillac Escalade IQ. Notably, the drop in demand appears limited to these larger EVs.
Approximately 160 of the plant’s 4,000 workers are expected to be impacted by the latest pause.
Meanwhile, GM introduced a more distinct product strategy in early summer. The company is once again placing greater emphasis on gasoline-powered vehicles in its powertrain lineup. Simultaneously, GM revealed plans to produce another ‘affordable next-generation EV’ at its Kansas plant.
GM reported a 73% increase in Hummer EV sales in the first half of 2025 compared to the same period in 2024, though this appears to be an outlier. During the same timeframe, the more affordable Optiq and Lyriq significantly outperformed the Escalade IQ, while the Silverado EV and Sierra EV pickups ranked among the slowest-selling electric models in GM’s portfolio.
