(Reuters) – The U.S. business of Fiat Chrysler Automobiles pleaded guilty to criminal conspiracy on Friday in U.S. District Court in Detroit in a plea agreement to resolve a multi-year Justice Department diesel emissions fraud probe, a court spokesman said. FCA US LLC, now part of Stellantis, will pay about $300 million in criminal penalties arising from its efforts to evade emissions requirements for more than 100,000 older Ram pickup trucks and Jeep sport-utility vehicles in its U.S. lineup. U.S. District Judge Nancy Edmunds set a July 18 sentencing date. (Reporting by David Shepardson)
