Auto Emissions Litigation

In September 2015, Volkswagen admitted that it had installed an emissions defeat device on millions of VW and Audi diesel models worldwide. The Dieselgate scandal prompted authorities to take a fresh look at other companies besides Volkswagen to determine whether these automakers may also have engaged in emissions cheating. These investigations uncovered evidence of emissions cheating by Audi on the company’s gasoline-powered models, as well as by General Motors on its GMC and Chevrolet diesel trucks.

Thousands of lawsuits have been filed against Volkswagen, Audi, and GM over the emissions cheating committed by these automakers. Drivers who purchased or leased one of the vehicles involved in these emissions cheating scandals may also qualify to file a lawsuit.

Dieselgate Lawsuits over VW and Audi Diesel Emissions Cheating

Volkswagen admitted that it had installed an emissions “defeat device” on 11 million VW and Audi diesel models worldwide in September 2011. The company’s emissions cheating was uncovered after an investigation by the California Air Resources Board (CARB) found that VW and Audi diesel models released far higher levels of nitrogen oxide (NOx) under normal driving conditions than they did during emissions testing.

Additional investigation by the CARB found that VW was misleading consumers and regulators about the emissions and performance of its 2.0 liter diesel models, including the following vehicles:

  • Audi A3 TDI, 2010-2015
  • Volkswagen Beetle TDI, 2012-2015
  • Volkswagen Beetle Convertible TDI, 2012-2015
  • Volkswagen Golf TDI, 2010-2015
  • Volkswagen Jetta TDI, 2009-2015
  • Volkswagen Jetta Sportswagen TDI, 2009-2014
  • Volkswagen Passat TDI, 2012-2015

In 2015, the EPA announced that it had also uncovered evidence of emissions cheating on 3.0 liter diesel models manufactured by Volkswagen, including the following models:

  • Audi A6 Quattro, 2014-2016
  • Audi A7 Quattro, 2014-2016
  • Audi A8 Quattro, 2014-2016
  • Audi A8L Quattro, 2014-2016
  • Audi Q5 Quattro, 2014-2016
  • Audi Q7, 2009-2016
  • Porsche Cayenne, 2013-2015
  • Volkswagen Touareg TDI, 2009-2016

As a result of the emissions cheating, thousands of car owners sued Volkswagen.  Heygood, Orr & Pearson represented hundreds of car owners affected by the Volkswagen emissions scandal.  The firm was also on the Plaintiffs’ Steering Committee appointed by the federal court to guide the Multidistrict Litigation that resulted in a record-setting $14.7 billion settlement.

Gasoline Emissions Cheating Lawsuits against Audi

In 2016, the CARB began investigating other automakers to determine whether defeat devices similar to those used in the Dieselgate scandal had been installed on other vehicles. The investigation uncovered emissions cheating software on Audi gasoline-powered vehicles, including the following models:

  • Audi A6, 2012-2016
  • Audi A7, 2012-2016
  • Audi A8, 2012-2016
  • Audi Q5, 2012-2016
  • Audi Q7, 2012-2017
  • Audi S4, 2012-2016
  • Audi S5, 2012-2016
  • Audi S6, 2012-2016
  • Audi S7, 2012-2016
  • Audi S8, 2012-2016

Audi allegedly installed an emissions defeat device on these gasoline vehicles in order to conceal their high CO2 emissions from consumers and regulators. Like the Dieselgate emissions cheating software, the defeat devices installed on Audi’s gas vehicles were designed to detect when the cars were undergoing emissions testing and lowering their emissions output from the higher levels released during normal driving conditions.

According to class action lawsuits filed against the company, Audi continued to manufacture and sell vehicles equipped with the emissions cheating software for eight months after news of the Dieselgate scandal was made public.  Heygood, Orr & Pearson represents hundreds of consumers who purchased or leased one of the gasoline models equipped with emissions cheating software.

GM Emissions Cheating on GMC and Chevrolet Diesel Trucks

General Motors is also facing allegations of emissions cheating on its diesel trucks after an investigation revealed that certain GMC and Chevrolet models had been equipped with a defeat device. The emissions software was designed to conceal the high NOx emissions levels of the following truck models:

  • Chevy Silverado 2500 HD Duramax diesel, 2011-2016
  • Chevy Silverado 3500 HD Duramax diesel, 2011-2016
  • GMC Sierra 2500HD Duramax diesel, 2011-2016
  • GMC Sierra 3500 HD Duramax diesel, 2011-2016

The defeat devices installed on these trucks are designed to override the trucks’ emissions control system when the vehicles are drive at temperatures below 68 degrees or above 86 degrees. According to lawsuits, the affected GMC and Chevy trucks emit 2- to 6-times the EPA’s maximum pollution levels under these driving conditions.

Drivers who purchased or leased one of the affected diesel truck models were charged about $5,000 more for their vehicles than comparable gasoline vehicles. However, the lawsuits allege, because of the emissions cheating software installed on the trucks by GM, drivers failed to receive the performance or environmental benefits in their trucks that were advertised by the automaker.
