GM to close Brownstown battery plant as lease nears end

General Motors is closing its Brownstown Battery Assembly Plant south of Detroit because its lease is nearing its end, a company spokesperson confirmed to TechCrunch. The closure is not related to GM’s electric vehicle strategy.

The plant assembled battery packs for Cadillac’s flagship electric vehicle, the Celestiq. It also made electric drive units and battery packs for the Chevrolet Corvette E-Ray, a plug-in hybrid.

GM said employees and work at Brownstown will move to other company facilities, but it did not identify them. Automotive News first reported the closure.

GM’s electric vehicle plans have faced changes since the One Big Beautiful Bill Act repealed incentives to produce and sell EVs. The company has reduced its public comments on EVs, but has not abandoned full electrification. It continues to make models including the Chevrolet Silverado EV and the limited-time Chevrolet Bolt.

The company is also researching lithium-manganese-rich and sodium-ion battery chemistries. It is rolling out a new $900 million facility to speed their commercialization.
