The lower profits took into account a 700-million-euro charge to deal with any future settlement over alleged illegal emissions devices in 104,000 U.S.-built Ram pickups and Jeep Grand Cherokees from 2014-2016. It also covers the costs of a software update to bring the vehicles into compliance.

The U.S. Justice Department sued Fiat Chrysler in May 2017 alleging that so-called "defeat device" software in the vehicles allowed them to emit fewer pollutants in lab tests than during normal driving. In the lawsuit, the government sought civil fines that could total over $4 billion, as well as court orders stopping the company from making or selling vehicles with undisclosed software.
