E.P.A. Accuses Fiat Chrysler of Secretly Exceeding Emissions Standards

The Environmental Protection Agency on Thursday accused Fiat Chrysler of using secret software that allowed illegal excess emissions from at least 104,000 diesel vehicles.

Affected models include the light-duty model year 2014, 2015 and 2016 Jeep Grand Cherokees and Dodge Ram 1500 trucks with 3-liter diesel engines sold in the United States, the agency said.

The software resulted in excess emissions of nitrogen oxides, which have harmful health effects, from the vehicles, the agency said.

The excess in emissions “threatens public health by polluting the air we breathe,” said Cynthia Giles, an assistant administrator at the E.P.A.

While Ms. Giles stopped short of calling the software “defeat devices,” which Volkswagen used to cheat on diesel emissions tests, she said, “There is no doubt that they are contributing to illegal pollution.”

Fiat Chrysler was not immediately available for comment.

Volkswagen has been engulfed in a scandal about cheating on emissions tests. Many of the company’s 600,000 cars in the United States that are equipped with emissions-cheating software were imported from Germany or Mexico.
