Fraudulent GM Diesel Emissions Claims

Lanier Law Firm Investigating Chevy Silverado and GMC Sierra “Clean Diesel” Pickups Over Fraudulent Emissions Claims

The Lanier Law Firm is investigating Chevy Silverado HD and GMC Sierra HD pickup trucks after examinations revealed that General Motors misled more than 700,000 U.S. buyers about emission performance of its Duramax diesel engines.

On the road, the Duramax engines produce pollutants – including NOx, which contributes to nitrogen dioxide, ozone and other harmful particulate matter in the air – up to five times higher than EPA maximum standards and in conflict with promises made to buyers in marketing and advertising material and on the showroom floor.

The Lanier investigation focuses on erroneous, inflated claims made by GM about its Duramax “clean diesel” engines, including pledges that its technology delivers low emissions coupled with increased performance. In fact, the automaker used software and related “defeat devices” that allowed the engines to mask their high pollution output during engine inspections while producing high levels of pollution under real driving situations.

GM’s use of technology to skirt diesel emissions tests mirrors emission-claims scandals involving diesel vehicles made by Volkswagen, Audi, Mercedes, and Fiat Chrysler America.

The Lanier Law Firm class action investigation affects the following vehicles:

  • 2011 – 2016 GMC Sierra 2500 HD and 3500 HD trucks
  • 2011 – 2016 Chevy Silverado 2500 HD and 3500 HD trucks
