GM Accused of Emissions Cheating for Diesel Pickups
General Motors has become the latest automaker to be sued for allegedly cheating on emissions testing with defeat devices on its diesel pickup trucks. The lawsuit seeks class-action status against both GM and German electronics company Bosch.
Owners and lessees of more than 705,000 GM diesel Sierra HD and Silverado models of heavy-duty trucks with Duramax-branded engines filed suit on Thursday, claiming that the defeat devices allow the trucks to emit two-to-five times the legal limit of dangerous nitrogen oxide (NOx) pollutants in real-world conditions ‒ and "many times" higher than their gasoline counterparts.
"To appeal to environmentally conscious consumers, GM markets its Silverado and Sierra Duramax vehicles as having low emissions, high fuel economy, and powerful torque and towing capacity. GM charges a premium of approximately $5,000 for diesel-equipped vehicles over comparable gas vehicles," the suit said.
The specific trucks named in the suit are the model year 2011-2016 GMC Sierra 2500HD and 3500 HD trucks, and Chevrolet Silverado 2500HD and 3500 HD trucks.
"GM's representations are deceptive and false, and GM sold these vehicles while omitting information that would be material to a reasonable consumer that GM has programmed its Silverado and Sierra Duramax vehicles to significantly reduce the effectiveness of the NOx reduction systems during realworld driving conditions," the suit said.
The named plaintiffs ‒ Andrei Fenner of Mountain View, California, who owns a 2011 Sierra, and Joshua Herman of Sulphur, Louisiana, who owns a 2016 Silverado ‒ said they would not have bought their trucks or would have paid less for them if they had known about the emissions cheating.
