WASHINGTON — The U.S. government is accusing Fiat Chrysler of failing to disclose software in some of its pickups and SUVs with diesel engines that allows them to emit more pollution than allowed under the Clean Air Act.
The Environmental Protection Agency said Thursday it had issued a "notice of violation" to the company that covers about 104,000 vehicles including the 2014 through 2016 Jeep Grand Cherokee and Ram pickups, all with 3-liter diesel engines. The California Air Resources Board took similar action.
"Failing to disclose software that affects emissions in a vehicle's engine is a serious violation of the law, which can result in harmful pollution in the air we breathe," said Cynthia Giles, EPA assistant administrator for enforcement and compliance.
Fiat Chrysler quickly issued a statement denying any wrongdoing.
The EPA said it will continue to investigate the "nature and impact" of the eight software functions identified through its testing. Regulators were not yet defining the software as so-called "defeat devices" intended to cheat on government emissions tests. However, the agency said that numerous discussions with Fiat Chrysler over the last year had not produced any suitable explanation for why the company had failed to disclose the software, which regulators said caused the vehicles to emit less pollution during testing than during regular driving.
