US Complaint Against Volkswagen, Audi and Porsche for Alleged Clean Air Act Violations

“The Department of Justice, on behalf of the Environmental Protection Agency (EPA), [on January 4, 2016] filed a civil complaint in federal court in Detroit, Michigan, against Volkswagen AG, Audi AG, Volkswagen Group of America Inc., Volkswagen Group of America Chattanooga Operations LLC, Porsche AG and Porsche Cars North America Inc. (collectively referred to as Volkswagen).  The complaint alleges that nearly 600,000 diesel engine vehicles had illegal defeat devices installed that impair their emission control systems and cause emissions to exceed EPA’s standards, resulting in harmful air pollution.  The complaint further alleges that Volkswagen violated the Clean Air Act by selling, introducing into commerce, or importing into the United States motor vehicles that are designed differently from what Volkswagen had stated in applications for certification to EPA and the California Air Resources Board (CARB)…Consistent with EPA’s Notices of Violation, issued on Sept. 18, 2015, for 2.0 liter engines and Nov. 2, 2015 for certain 3.0 liter engines, the complaint alleges that the defeat devices cause emissions to exceed EPA’s standards during normal driving conditions.  The Clean Air Act requires vehicle manufacturers to certify to EPA that their products will meet applicable federal emission standards to control air pollution.  Motor vehicles equipped with illegal defeat devices cannot be certified. The complaint alleges that Volkswagen equipped certain 2.0 liter vehicles with software that detects when the car is being tested for compliance with EPA emissions standards and turns on full emissions controls only during that testing process.  During normal driving situations the effectiveness of the emissions control devices is greatly reduced.  This results in cars that meet emissions standards in the laboratory and at the test site, but during normal on-road driving emit oxides of nitrogen (NOx) at levels up to 40 times the EPA compliance level.  In total, the complaint covers approximately 499,000 2.0 liter diesel vehicles sold in the United States since the 2009 model year. The complaint further alleges that Volkswagen also equipped certain 3.0 liter vehicles with software that senses when the vehicle is undergoing federal emissions testing.  When the vehicle senses the test procedure, it operates in a “temperature conditioning” mode and meets emissions standards.  At all other times, including during normal vehicle operation, the vehicles operate in a “normal mode” that permits NOx emissions of up to nine times the federal standard.  In total, the complaint covers approximately 85,000 3.0 liter diesel vehicles sold in the United States since the 2009 model year…”
