A strike at a GM supplier plant in Michigan could jeopardize the automaker’s truck output as competition in the highly profitable segment continues to intensify.
The details: United Auto Workers at the Three Rivers plant in Michigan—a company owned by Dauch Corp., formerly known as American Axle Manufacturing—hit the picket lines Monday over claims that employee wages have failed to keep pace with inflation, CNBC reported.
The plant makes axle components for GM’s Chevrolet Colorado and GMC Canyon midsize pickup trucks, as well as heavy-duty Chevrolet Silverado and GMC Sierra pickups.
Three Rivers, where union officials say current wages top out at $22 an hour after a five-year progression, also produces additional components for Silverado and Sierra pickups.
The facility also manufactures components for Stellantis’ Chrysler Pacifica minivan.
GM has roughly two weeks of axle inventory on hand to continue building its trucks, according to sources cited by Reuters.
What they’re saying: “The company believes that the best outcomes for everyone — our associates, the union, and the company — are reached at the bargaining table. We remain committed to negotiating with the union in good faith and hope to promptly reach a fair agreement,” said the Dauch Corp., per a company statement.
Why it matters: Any disruption to GM truck production could quickly tighten inventory levels, potentially affecting dealers’ access to some of their most profitable and fastest-turning vehicles at a critical time for the highly competitive truck segment.

Between the lines: The potential impact of the Three Rivers plant strike cannot be understated, given the timing of the walkout and competitors working aggressively to gain market share whenever opportunities arise.
Ford saw its total U.S. new-vehicle sales decline 8.8% in the first quarter compared with Q1 2025, due in part to F-Series inventory challenges stemming from two fires at a supplier plant.
Amid Ford’s dip in truck sales, Ram posted a 20% gain in the segment, with CEO Tim Kuniskis looking for additional ways to expand the brand’s market share.
What they’re saying: "It's really, really expensive (to poach buyers), so you try not to," said Kuniskis, per the Detroit Free Press. "Because Ford in particular is over 80% loyalty. So, you can get somebody that wants a Ford to come and buy your vehicle. But you're gonna have to give them a really compelling reason to give up that loyalty, because it may be generational loyalty."
Bottom line: If GM’s supply disruption extends beyond its current inventory cushion, rival brands could have an opportunity to capture truck buyers unwilling to wait for delayed deliveries, making it critical for dealers to closely monitor inventory levels and allocation updates in the highly competitive pickup segment.
