EPA Serves FCA Notice for Cheat Software in Diesels


Another diesel titan has found itself in the EPA’s bad books. The Environmental Protection Agency has served a notice to Fiat Chrysler Automobiles advising them that their diesels are in violation. As it’s only a notice, this doesn’t affect sales of FCA vehicles equipped with their EcoDiesel engines. EPA claims that FCA is using several layers of software to detect when the vehicle is being tested. It then modifies the engine to falsify the nitrous oxide output. There are uncanny similarities to the Volkswagen cheat all over again. According to the notice, the EPA has questions about eight separate pieces of software that activate during vehicle emissions testing.

FCA for its part claims they have committed no wrongdoing. Both FCA and the EPA have already tried to come to an agreement on the issue, but neither side is seeing eye to eye. FCA has not provided the EPA with a good reason why the software(s) were not disclosed at testing. FCA is also on the hook to prove that the software is not a defeat device. A statement from FCA expressed disappointment that the EPA has taken this route. FCA is adamant that its “…emissions control systems meet the applicable requirements.” FCA, with sales in decline, is not in the same position to weather any potential scandal or fines, unlike VW, who had just reached top automobile maker. About 100,000 Ram and Jeep vehicles have shipped with the EcoDiesel engine since first introduction in 2016.
