Fiat Chrysler is being sued for an alleged defect in the emissions systems of some trucks that can result in a 25% drop in fuel economy, according to a lawsuit filed by the firm Hagens Berman.

The lawsuit says Fiat Chrysler sold hundreds of thousands of 2013 to 2017 RAM 2500 and 3500 pickup trucks with faulty emissions systems. 

Owners who brought their trucks in for a repair of the systems found that the fix resulted in dramatically lower fuel economy.
