Volkswagen Investigated by EPA Over Clean Air Standards

Keller Rohrback L.L.P., a leading national consumer law firm, is investigating allegations that automakers Volkswagen AG(ETR:VOW3), Audi AG (ETR:NSU), and Volkswagen Group of America (“Volkswagen”) used software in diesel vehicles to knowingly violate emissions standards.

Yesterday, the EPA issued a Notice of Violation stating that Volkswagen allegedly designed and installed “defeat devices” to detect when a vehicle is undergoing official emissions testing, and to turn full emissions controls on only during that test. The full emissions controls are not activated during normal driving, which may enhance vehicle performance.


According to the EPA, the affected models include:  

• Jetta (Model Years 2009 – 2015) 
• Jetta Sportwagen (Model Years 2009 – 2014)
• Beetle (Model Years 2012 – 2015)
• Beetle Convertible (Model Years 2012 – 2015) 
• Audi A3 (Model Years 2010 – 2015) 
• Golf (Model Years 2010 – 2015)
• Golf Sportwagen (Model Year 2015) 
• Passat (Model Years 2012 – 2015)  

The EPA said that Volkswagen violated the Clean Air Act by installing the devices to “bypass, defeat, or render inoperative elements of vehicles’ emission control system.” The devices were allegedly installed in certain model year 2009 through 2015 diesel light-duty vehicles.

“The main reason why someone pays more to drive a ‘green’ car is because it’s better for human and environmental health. By installing ‘defeat devices,’ VW has betrayed consumers’ and regulators’ trust, and has profited from selling the cars at a premium,” said longtime consumer advocate Lynn Lincoln Sarko, the managing partner of Keller Rohrback L.L.P.

The defeat devices expose the public to harmful pollutants including unsafe carbon monoxide emissions, nitrogen oxides, ground-level ozone, and fine particle matter, according to the EPA. The federal agency said exposure to such pollutants potentially increases the public’s susceptibility to “a range of serious health effects, including increased asthma attacks and other respiratory illnesses,” some of which can result in hospitalization.

The EPA said the levels of nitrous oxide being emitted is 10 to 40 times what is allowed under emission standards.

The New York Times reports that the Obama administration ordered Volkswagen to “recall nearly a half million cars from the road” today. The California Air Resources Board also sent a letter to Volkswagen stating that it is investigating “all model-year 2009 through 2015 light-duty diesel vehicles equipped with 2.0 liter engines,” suggesting the problem could be more widespread.
