Class-action suit against Volkswagen filed by state law firms

With allegations swirling that Volkswagen tampered with its emissions equipment on VW and Audi vehicles, two Wisconsin law firms have entered the fray and filed a lawsuit in U.S. District Court against the German automaker.

According to a news release, Habush Habush & Rottier SC and Hawks Quindel SC are seeking class-action status for the suit, which will roll together numerous lawsuits by state residents who bought a diesel Volkswagen after 2009.

The EPA claims Volkswagen employed a software trick to get nearly 500,000 U.S. cars labeled “Clean Diesel” to switch from a “clean” driving mode during tests to emitting higher levels of pollutants once testing was finished.

According to Habush Habush & Rottier, the VW cars in question produced up to 40 times the EPA-allowed amount of nitrogen oxide in their exhaust. Other states have filed similar lawsuits against Volkswagen.
