Lawsuit Filed Against Audi by HO&P Over Gasoline Emissions Cheating

by Charles Miller

Heygood Orr & Pearson is representing clients in lawsuits being filed against Audi accusing the company of installing a software defeat device on certain gasoline powered models in order to hide the emissions levels of these vehicles. Audi is currently facing a number of lawsuits filed on behalf of vehicle owners who purchased or leased one of the vehicles equipped with the defeat device. 

Charles Breyer, a federal judge in San Francisco, is presiding over the federal Audi CO2 lawsuits involving the emissions “defeat devices.”

Audi installed a software defeat device on its A6, A7, A8, and Q5 models equipped with 3.0 liter or larger gasoline-powered engines and automatic transmissions. This defeat device – used on hundreds of thousands of Audi models – was designed to hide the carbon dioxide (CO2) emissions levels of these cars during vehicle testing.

Audi allegedly began manufacturing and selling vehicles equipped with a CO2 defeat device as early as 2013, if not earlier. Documents uncovered by the California Air Resources Board (CARB) have shown that Audi installed the software defeat device on the affected vehicles models as late as May 2016.

Audi continued to manufacture and sell vehicles equipped with a CO2 emissions cheating software for at least eight months after its parent company, Volkswagen, admitted to having installed defeat devices on millions of VW, Audi, and Porsche diesel models.

Consumers who purchased or leased one of the affected Audi models were overcharged for vehicles that failed to comply with U.S. environmental regulations, while simultaneously incurring higher fuel costs due to Audi’s deliberate deception.
