The Environmental Protection Agency said Fiat Chrysler violated the Clean Air Act by allegedly installing and failing to disclose software in some 104,000 cars and trucks that alters emissions.
The software was found in two models, according to the EPA: light-duty model year 2014, 2015 and 2016 Jeep Grand Cherokees and Dodge Ram 1500 trucks with 3.0 liter diesel engines sold in the United States.
The software is designed such that during the emissions tests, Fiat Chrysler’s diesel cars meet the standards that protect clean air, however under normal driving conditions, the software directs the emissions control system to operate differently, resulting in emissions that can be much higher.
Fiat Chrysler was required by law to disclose the software to regulators during the certification process but did not do so. The company has offered to make extensive changes to its software to address EPA concerns.
These inquiries are similar to the Volkswagen diesel emissions cheating scheme, which has resulted in over $19 billion in penalties and compensation.
