GM to Pause Chevy Blazer Gas Model and Onshore Production to Tennessee in 2027
General Motors will pause Chevrolet Blazer gasoline model production in Ramos Arizpe, Mexico after September 2026 and shift assembly exclusively to Spring Hill, Tennessee in Q2 2027. About 700 of 1,400 Spring Hill workers face temporary layoffs until May 11 as the plant retools for gasoline and electric vehicle production.
1. Production Gap and Onshoring
GM will end gasoline Chevrolet Blazer assembly at Ramos Arizpe, Mexico, in September 2026 and resume production at its Spring Hill, Tennessee plant in Q2 2027, making it the exclusive site for the gas-powered model.
2. Workforce Layoffs and Plant Retooling
Approximately 700 of the 1,400 shift workers at Spring Hill are on temporary layoff until May 11 while the facility installs equipment to accommodate simultaneous gasoline and electric vehicle assembly.
3. Investment Background
This onshoring move is part of GM's June 2025 announcement of a $4 billion investment across three U.S. factories, aimed at localizing production and mitigating tariff risks by upgrading Orion Assembly in Michigan and Fairfax Assembly in Kentucky.
4. Strategic Implications
Shifting Blazer production to the U.S. could reduce logistics costs and exposure to tariff-related expenses but creates a production gap that may temporarily dent GM's SUV lineup availability and revenue in late 2026.
