ABOUT THE CASE

A Hagens Berman investigation revealed that Mercedes knowingly programmed its Clean Diesel vehicles to emit illegal, dangerous levels of nitrogen oxide (NOx) in virtually all real-world driving conditions. Its vehicles likely contain a "defeat device" used to cheat testing that hide the dangerous and polluting materials, in similar fashion to what Volkswagen did in Volkswagen's Dieselgate scandal. An investigation by the United States Department of Justice and Environmental Protection Agency followed the law firm’s pursuit. Mercedes’ conduct led to a decrease in resale value of its impacted vehicles, as well as increases in environmental pollution. The active case against Mercedes is ongoing.
