According to the firm's lawsuit, much like VW, Fiat Chrysler and Mercedes, GM has intentionally sold GMC Sierra Duramax Diesel 2500 HD and 3500 HD vehicles with emissions-cheating devices that mask the vehicle's release of illegally high levels of NOx. The use of these “defeat devices” means consumers paid a $5,000 premium for a diesel car that is, in fact, emitting illegal levels of deadly NOx emissions. GM knew consumers would pay more for a powerful and efficient diesel option, and used these devices to obtain the power and performance it wanted, while hiding illegal levels of pollution.

EMISSIONS CHEATING EXPLAINED
According to our investigation, GM intentionally installed multiple emissions-cheating devices in affected GMC Sierra trucks, in violation of federal requirements. We believe GM was motivated by its desire to increase sales and profits, and without cheating emissions the Sierra trucks could not achieve the fuel economy, range, towing power or performance GM promised its customers. The emissions-cheating devices engage emissions controls at temperatures within which emissions tests must be done, but outside that temperature range emissions controls are turned down or “de-rated.” Another defeat device de-rates emissions controls after 5 to 10 minutes of steady (i.e., highway) driving, which never happens during an emissions test. These devices combine to allow the trucks to pass emissions tests while masking the vehicle's true output of NOx during actual on-road driving.
Affected Sierra Duramax diesels exceed by two to five fold the Federal and California NOx emissions limits and cost an estimated $5,000 more than their gasoline equivalent.
YOUR CONSUMER RIGHTS
Hagens Berman believes that consumers have the right to reimbursement for the premium price they paid for what they thought was a powerful, efficient and emissions-compliant option. According to the firm's investigation, GM charged consumers high prices for vehicles that are in fact emitting illegally high emissions, rendering them out of compliance with federal regulations. Simply put, thousands of consumers did not receive what they paid for, and purchased their Silverado under what we believe is false information.
