General Motors is prepared to duke it out over a class action lawsuit. The lawsuit claims the automaker used three “defeat devices” to allow Chevrolet Silverado and GMC Sierra pickups equipped with the Duramax diesel engine to pollute two to five times the legal limit.
GM released an official statement over the allegations. It simply reads:
“These claims are baseless and we will vigorously defend ourselves. The Duramax Diesel Chevrolet Silverado and GMC Sierra comply with all U.S. EPA and CARB emissions regulations.”
The lawsuit covers the 2011-2016 model years of Silverado and Sierra pickup trucks totaling 705,000 vehicles. Multiple law firms filed the lawsuit, chiefly among them is Hagens Berman Sobol Shapiro. The firm notably helped owners and dealerships reach multi-billion settlements over Volkswagen’s over-polluting cars.
Auxiliary emission control devices are legal under federal law, though their presence must be disclosed to federal agencies and their purpose fully explained. It’s this caveat that has led the United States Department of Justice to serve Fiat-Chrysler Automobiles with a lawsuit; FCA has been unable to properly explain the presence of eight auxiliary emission control devices.
GM has bet big on diesel vehicles as of recent. The 2017 Chevrolet Cruze diesel is the first of many oil-burners slated. The 2018 Chevrolet Equinox and 2018 GMC Terrain are on deck for the same diesel engine as well. In the meantime, GM has invested into a new generation of diesel engines for Cadillac.
