Hard NOx: General Motors Accused of Rigging Diesel-Pickup Emissions

Automaker General Motors saw negative reaction this week on accusations that their diesel emission systems are causing significant harm to the environment. The class action lawsuit stipulates that the impact is worse than that of the recent Volkswagen scandal for it’s own TDI engines. GMC has denied the accusations and vows to argue their position further within the court system.

Key Takeaways:

  • A class-action lawsuit accuses General Motors of rigging emission-control systems on 2011–2016 Chevrolet Silverado HD and GMC Sierra HD pickup trucks.
  • If the allegations are proved true, the environmental damage from these 705,000 trucks could easily exceed that of the Volkswagen’s emission-test-cheating TDI engines.
  • Notably, these accusations have not yet come from regulators or any federal investigation by the EPA.

“The suit claims that GM used at least three defeat-device tricks in these trucks.”
