GM denies allegations of emissions cheating on Chevy and GMC Duramax diesel trucks

by Charles Miller

General Motors released a statement denying allegations of emissions cheating involving its Chevrolet Silverado and GMC Sierra Duramax diesel truck models. GM is facing a class action lawsuit involving allegations that it installed emissions “defeat devices” on these vehicles, as well as other lawsuits filed on behalf of individual Chevy and GMC truck owners.

According to the class action lawsuit filed against GM in May, the company installed computer software “defeat devices” on 2011-2016 Chevrolet Silverado and GMC Sierra 2500 HD and 3500 HD Duramax diesel truck models. The lawsuit alleges that these defeat devices were programmed to limit the nitrogen oxide (NOx) emissions of the affected truck models under certain conditions, causing them to emit lower levels of greenhouse gases than they do under normal driving conditions.

In response to these emissions cheating allegations, GM released a statement claiming that the allegations in the class action lawsuit were false. “These claims are baseless and we will vigorously defend ourselves,” the company said. “The Duramax Diesel Chevrolet Silverado and GMC Sierra comply with all U.S. EPA and CARB emissions regulations.”

More than 700,000 Chevy and GMC trucks were equipped by GM with the emissions control systems allegedly containing the defeat devices. This system – known as an electronic diesel control (EDC) system – was manufactured by Bosch, which has also been embroiled in auto emissions scandals involving Volkswagen and Chrysler.

According to the class action lawsuit against GM, consumers who purchased one of the Chevy or GMC diesel trucks affected by the automaker’s alleged emissions cheating paid about $5,000 more for these vehicles than they would have for comparable gasoline-powered models. Owners of one of the affected truck models may be eligible to take legal action against GM for the excess costs they have incurred for the environmental and performance benefits that were advertised by the company.
