On Wednesday, February 18th, 2026, Miller Shah LLP filed a class action lawsuit on behalf of the City of Milwaukee against three Fire Truck manufacturers and industry trade association for violating the Sherman Act and several individual state antitrust and consumer protection laws.
The Complaint alleges that Fire Truck manufacturers Oshkosh Corporation, REV Group, Inc and Rosenbauer America LLC shared competitively sensitive information through Fire Apparatus Manufacturers’ Association, enabling them to limit the supply of Fire Trucks through sustained backlogs and inflated prices.
According to the Complaint, the Manufacturer Defendants have sustained elevated prices by limiting supply through production backlogs, and increased wait times. Despite these extended delays and soaring prices, the Complaint alleges that the Manufacturer Defendants' market share has remained relatively unchanged due to the conduct alleged. The Complaint alleges that the effects of these alleged anticompetitive behaviors have been substantial for fire departments across the country, hindering their ability to protect public safety.
Earlier this year, a petition for multidistrict litigation was filed to consolidate the related action. MDL No. 3179.
The city is represented by James C. Shah and Natalie Finkelman Bennett of Miller Shah LLP and Joseph D. Newbold and Douglas Dehler of O’Neil, Cannon, Hollman, DeJong & Laing S.C.
The case is City of Milwaukee et al v. Oshkosh Corporation et al., case number 1:2026cv00271, in the U.S. District Court for the Eastern District of Wisconsin.
