Production of the Bollinger B4 started this week in Michigan.
The official legal complaint also accuses Munro designer Ross Compton, a former Bollinger contractor, of violating his non-disclosure agreement.
Bollinger is an electric off-roader startup that had been struggling in recent years, even with 50,000 pre-orders under its belt.
Roush Industries will assemble Bollinger's line of all-electric platforms and chassis cabs for Classes 3 through 6 commercial vehicles.
