    Volkswagen definitely won't be the only major automaker hauled into court for cheating on diesel emissions tests in recent years. In the wake of EPA accusations from January, the US Department of Justice has sued Fiat Chrysler for allegedly using a combination of defeat devices and software to trick regulators into thinking its 3.0-liter EcoDiesel engines are... well, eco-friendly. Reportedly, 2014-2016 model year Ram 1500 and Jeep Grand Cherokee vehicles (104,000 in total) violated the Clean Air Act by meeting emissions rules in EPA testing, but spewing "much higher" nitrogen oxide levels in certain everyday driving situations.
