General Motors is closing its Brownstown Battery Assembly Plant located near Detroit. The facility was responsible for producing battery packs for the Cadillac Celestiq, as well as electric motors and batteries for the Chevrolet Corvette E-Ray plug-in hybrid.
A company spokesperson stated that the closure is due to the expiration of the site's lease agreement rather than a shift in electric vehicle strategy. Affected employees and production operations are scheduled to be relocated to other General Motors manufacturing facilities.
The company is also adjusting its production targets for the new Chevrolet Bolt. Current projections indicate that output will reach approximately 35 000 vehicles by the first quarter of 2027, a significant reduction from the original plan of 150 000 units.
Since the second quarter of 2025, General Motors has reported $10,9 billion in charges associated with its electric vehicle division. These adjustments follow the elimination of the $7 500 US federal purchase incentive in September 2025, which led to a decline in battery-electric vehicle sales.
