Chevy, GMC diesel truck owners file amended lawsuit against GM in emissions cheating class action

by Eric Pearson

Chevrolet Silverado and GMC Sierra Duramax diesel truck owners have filed an amended complaint in their emissions cheating class action against General Motors. The lawsuit accuses GM of emissions cheating on 2011-2016 Chevy Silverado and GMC Sierra 2500 HD and 3500 HD diesel pickup trucks.

According to the lawsuit, GM installed an emissions defeat device on about 700,000 Silverado and Sierra Duramax diesel trucks. This device made the vehicles appear to emit acceptable levels of emissions in order to pass emissions inspections. When the vehicles are driven at temperatures below 68 degrees or above 86 degrees, however, the trucks can emit nitrogen oxide (NOx) emissions that are up to four to five times federal pollution limits.

The amended lawsuit highlights the role that auto parts maker Bosch played in GM’s alleged emissions cheating. According to the new complaint, Bosch supplied parst to GM that enabled the company to mislead consumers and regulators about the emissions levels of Chevy Silverado and GMC Sierra Duramax diesel trucks, making them appear to comply with federal emissions laws.

The new complaint also highlights the effect of GM’s emissions cheating when the affected Chevy Silverado and GMC Sierra diesel trucks are driven in hilly conditions. According to recent tests, when GM diesel trucks that have been outfitted with the emissions cheating software supplied by Bosch are driving in hilly conditions, the vehicles emit two to three times the EPA’s 200 mg/mile NOx emissions limit. When the trucks are driven at temperatures about 86 degrees, they can emit NOx levels as high as 3,893 mg/mile – nearly 20 times the EPA maximum.

Drivers who own or leased one of the Chevy or GMC trucks affected by GM’s emissions cheating may experience decreased performance, higher emissions, and unforeseen costs involving their vehicles. GM charged drivers about $5,000 more for the diesel models affected by their emissions cheating than for comparable gasoline-powered models, while failing to deliver the increased performance and fuel efficiency that they promised for these vehicles.

Bosch also supplied parts to Audi, Chrysler, Mercedes Benz, and Volkswagen that were used in the alleged emissions cheating committed by these companies. In July 2016, Volkswagen agreed to pay $14.7 billion to settle allegations that it had installed a software defeat device on thousands of “TDI Clean Diesel” vehicles sold in the U.S. Emissions cheating lawsuits against Audi and Chrysler are still pending in court.
