General Motors is set to shutter a battery assembly facility located south of Detroit, as confirmed by a company representative to TechCrunch.
The Brownstown Battery Assembly Plant was responsible for manufacturing battery packs for the Cadillac Celestiq, GM’s flagship electric vehicle, as well as electric drive units and battery packs for the Chevrolet Corvette E-Ray, a hybrid variant of the iconic sports car. This closure was first reported by Automotive News.
According to the spokesperson, the decision to close is not linked to GM’s electric vehicle plans. Instead, the facility was leased, and the lease agreement was approaching its conclusion.
Staff and operations from the Brownstown plant will transition to other GM locations, though the specific sites have not been specified by the company.
GM, like many in the automotive sector, faced challenges with its electrification plans after significant legislative changes implemented by the One Big Beautiful Bill Act, which revoked incentives for EV production and sales last year.
In light of these developments, GM has scaled back its public discussions regarding electric vehicles but remains committed to achieving full electrification in the future.
The company continues to manufacture various electric models, such as the Chevrolet Silverado EV and the limited-edition Chevrolet Bolt. Additionally, GM is actively researching new battery technologies, including lithium-manganese-rich and sodium-ion batteries, and is investing in a new facility worth $900 million to accelerate the commercialization process.
