UAW Strikes GM Pickup Truck Axle Supplier Dauch Corp. After Contract Talks Fail

The United Auto Workers union launched a strike on June 1, 2026, at Dauch Corp., a key supplier of axles for General Motors Co. (NYSE: GM) pickup trucks, following failed contract negotiations. The walkout threatens to disrupt production of GM’s Chevrolet Silverado and GMC Sierra, two of its most profitable vehicles. Dauch Corp. is a critical link in GM’s supply chain, and the halt in axle shipments could force GM to temporarily idle truck assembly plants within days. The automaker is facing pressure as it seeks to meet robust demand for full-size pickups. The union cited disagreements over wages and benefits as the reason for the strike. The UAW has increasingly targeted Tier 1 suppliers as a strategic tool to gain leverage in broader labor disputes. GM did not immediately comment on potential mitigation measures.
