US sues Fiat Chrysler for 'using software to beat emissions tests'

The US government is suing Fiat Chrysler, alleging that some diesel pick-up trucks and Jeep SUVs cheat on emissions tests.

The lawsuit filed by the Justice Department on Tuesday alleges that nearly 104,000 Ram pick-ups and Jeep Grand Cherokees from the 2014 to 2016 model years have software that allows them to emit lower amounts of pollutants during lab tests by the Environmental Protection Agency (EPA) than during normal driving conditions.
