A proposed class action lawsuit is alleging Ford Motor Company cheated on the diesel emissions testing of 500,000 F-Series Super Duty pickups. The lawsuit is naming both Ford and supplier Robert Bosch GmbH of Germany as defendants. Bosch has been involved in other diesel emissions scandals, including Volkswagen AG’s 2015 scandal.
The lawsuit was filed Wednesday in U.S. District Court for the Eastern District of Michigan in Detroit by law firm Hagens Berman. The complain covers F-250 and F-350 Super Duty diesels sold from 2011 to 2017, which accounts for about 500,000 vehicles in the U.S.
Attorneys representing the plaintiffs state the impacted vehicles exhibit real-world emissions performance that “grossly exceeds” those allowed by federal and state law. The complaint details allegations that Ford and Bosch crafted software that treats real-world applications differently than tests conducted by both the Environmental Protection Agency (EPA) and California Air Resources Board (CARB).
Ford has denied any wrongdoing in the matter and has vowed to defend itself in the case. Robert Bosch GmbH has also denied wrongdoing with regards to Ford vehicles.
This lawsuit presents Ford as the latest automaker to come under fire for diesel emissions issues following Volkswagen AG’s infamous “diesel-gate” in 2015. BMW, Mercedes-Benz, General Motors and Fiat-Chrysler Automobiles have all faced similar litigation over diesel emissions.
