Consumers are suing General Motors for allegedly rigging the emissions controls in Duramax diesel trucks in order to pass emissions tests, while in real world conditions the trucks emit 2 to 5 times the legal limits of deadly NOx pollutants, according to Hagens Berman.
The lawsuit states that GM did so all to increase the vehicles’ power and efficiency, and thus the appeal of its best-selling pick-up trucks. The complaint identifies and describes three distinct “defeat devices,” which turn down or “de-rate” the emissions controls in place compared to when the vehicles are in a testing environment.
Vehicle owners are represented by leading auto defect consumer-rights law firm, Hagens Berman, which has been involved in many of the largest automotive settlements in U.S. history, including the $10 billion Volkswagen diesel emissions settlement, the $1.3 billion Volkswagen dealer settlement and the $1.6 billion consumer settlement against Toyota. Based on its testing of emissions control systems, the firm is also leading litigation against Chevrolet, Fiat-Chrysler and Mercedes for illegal use of emissions-cheating software. The level of excess NOx emissions from GM trucks is 2 to 5 times the legal limits, and there are estimated to be at least 705,000 of these big trucks on the road.
