General Motors has pulled the trigger on production halts and job cuts at three separate Michigan assembly plants over the past year, and the company’s own statements tie every one of them to the same story: a retreat from electric vehicle timelines and a scramble to keep gas-powered trucks and sedans on dealer lots. Flint Assembly’s downtime stretched deep into 2026, Lansing Grand River is losing 350 workers as it swaps an EV sedan plan for a gas-powered Cadillac CT5, and Factory Zero has already cut more than 1,200 jobs outright.

Key Points

• Flint Assembly’s holiday shutdown ran through January 26, 2026 — longer than a standard seasonal closure — for what GM called “planned shop renovations.”
• Lansing Grand River is cutting 350 workers starting January 14, 2027 as the plant retools from a planned EV line to a next-generation gas Cadillac CT5.
• Factory Zero in Detroit-Hamtramck permanently laid off more than 1,200 workers in October 2025, then temporarily idled another 1,300 for a month in March 2026.
• GM has now redirected three separate assembly plants away from electric vehicle plans within roughly a year, according to its own public statements.

Flint Assembly’s truck-plant downtime ran longer than planned

Flint Assembly builds the heavy-duty Chevrolet Silverado HD and GMC Sierra HD, and GM extended its holiday shutdown well past a typical seasonal break, keeping the plant idle from late December 2025 until January 26, 2026. GM spokeswoman Jennifer Korail told Mid-Michigan NOW the plant “will take an extended downtime in January to complete planned shop renovations,” pointing to retooling ahead of next-generation heavy-duty trucks. The stretch left thousands of hourly workers on temporary layoff status under the GM-UAW national contract.

Lansing Grand River trades an EV sedan plan for a gas CT5

GM took a $500 million federal grant in 2024 to help convert Lansing Grand River toward electric vehicle production, and it’s now retooling the plant for a gasoline-powered Cadillac CT5 instead, according to Detroit News reporting on GM’s own statements. The current CT5 stops production on December 17, 2026, and 350 employees will be laid off starting January 14, 2027 while the plant is reworked as part of a $1.25 billion investment. “As Cadillac evolves, we will continue to make necessary adjustments to our portfolio to meet customer demand,” Global Cadillac Vice President John Roth said in GM’s statement, as WLNS 6 News reported. Affected workers can draw supplemental pay equal to 74% of their hourly wage under the union contract while GM plans to recall them once retooling wraps up.

Factory Zero has already shed over a thousand EV jobs

Detroit-Hamtramck’s Factory Zero builds the GMC Hummer EV, Chevrolet Silverado EV, GMC Sierra EV and Cadillac Escalade IQ, and it’s absorbed the deepest cuts of the three plants. GM eliminated one of the plant’s two shifts on October 29, 2025, permanently laying off more than 1,200 workers, citing “slower near-term EV adoption and an evolving regulatory environment,” per FOX 2 Detroit’s coverage of the company’s statement. GM followed that with a separate, temporary idling of roughly 1,300 remaining workers for about a month starting mid-March 2026, telling Detroit News it needed to “align EV production with market demand.”

Three plants, three retooling jobs, one direction: GM keeps redirecting capacity earmarked for electric vehicles back toward gas-powered trucks and sedans, a shift Yahoo Finance notes has now touched a plant that took federal EV conversion money as recently as 2024. GM hasn’t framed any of these moves as permanent closures — every announcement includes language about eventual recalls or supplemental pay under the UAW contract — but the pattern across Flint, Lansing and Factory Zero shows how far the company’s near-term production plans have drifted from its EV rollout targets of a few years ago.
