California Department of Justice v. Cummins Inc.

Cummins Inc. allegedly violated California engine emission control and certification requirements. According to CA-AG, Cummins made undisclosed changes to approximately 120,000 engines in California after CARB had certified the engines for sale. In addition, roughly 2,000 Cummins engines had undisclosed auxiliary emission control devices that altered the emissions control system and resulted in emissions in excess of regulatory limits.
