GM Fairfax Assembly

GM Fairfax Assembly (formally Fairfax Assembly & Stamping) is General Motors’ automobile plant in the Fairfax Industrial District of Kansas City, Kansas — the direct successor to the World War II B-25 bomber plant, giving the Fairfax site a continuous run of manufacturing since the 1940s. GM has assembled cars here since 1945; the current ~4.9-million-square-foot “Fairfax II” plant opened for the 1988 model year. As of the mid-2020s the plant is being retooled to build electric vehicles — GM’s next-generation Chevrolet Bolt EV — in a roughly $390 million transition.

From bombers to cars

After World War II, General Motors took over the former North American Aviation B-25 bomber plant in the Fairfax district and converted it to automobile assembly under its Buick-Oldsmobile-Pontiac Assembly Division.¹ In an unusual Cold War hybrid, the plant built F-84F jet fighters alongside cars in 1952 during the Korean War.¹ The original plant ran until May 1987, when GM opened a new ~$1 billion “Fairfax II” plant on the grounds of the former Fairfax Airport; Fairfax II began production with the 1988-model-year Pontiac Grand Prix.¹

The modern plant

Fairfax Assembly & Stamping is a roughly 4.9-million-square-foot plant whose workers are represented by United Auto Workers Local 31.¹ Over the decades it has built the Pontiac Grand Prix, the Oldsmobile Cutlass Supreme, the Saturn Aura, and — most recently — the Chevrolet Malibu and Cadillac XT4.¹ Wikipedia lists “over 2,200” hourly and salaried employees; it is consistently described as one of Wyandotte County’s largest employers (a “~3,000 workers” figure appears in secondary sources but could not be verified: “).¹

The electric-vehicle transition

In May 2024 GM announced it would retool Fairfax for electric vehicles, investing about $390 million to build its next-generation, Ultium-based Chevrolet Bolt EV at the plant.²³ Under the plan, Chevrolet Malibu production ended in November 2024, Cadillac XT4 production paused after January 2025, and the plant was idled for retooling with production set to resume in late 2025 — at which point Fairfax was slated to build the Bolt EV (and the XT4) on the same line.² GM said the retooling would involve temporary layoffs of about 680 workers during the transition.⁴

(Reporting after May 2024 suggested Fairfax’s product plan continued to evolve — with additional GM investment and gas-vehicle production such as the Chevrolet Equinox reportedly added — but those later details are “ pending a directly-retrieved primary source.)

Significance

GM Fairfax Assembly is one of the anchor employers of Kansas City, Kansas, and the living end of a manufacturing story that began with wartime bombers. Auto production has continued on the Fairfax site without interruption since 1945 — B-25s, then Pontiacs and Oldsmobiles and Saturns and Chevrolets, and next electric Chevrolets — making it perhaps the most durable single thread of Kansas City’s industrial history.
