GoKawiilGM confirms closure of Brownstown battery assembly plant near Detroit
GM is shutting down its Brownstown Battery Assembly Plant south of Detroit, which supplied battery packs for the Cadillac Celestiq and battery packs and drive units for the Corvette E-Ray. A GM spokesperson told TechCrunch the closure stems from an expiring lease on the site, not the company's EV strategy, and that affected employees and work will be relocated to other GM facilities.
GoKawiil's interpretation of the reporting above, not reported fact.
The closure comes as GM has scaled back public messaging on EVs following the repeal of federal EV incentives under the One Big Beautiful Bill Act, which could make the timing look strategic even though GM attributes it to a routine lease expiration. GM's continued investment in EV models and a new $900 million battery research facility suggests the company is not abandoning electrification, but is recalibrating how it talks about and organizes that effort amid a less favorable policy environment.
