Fiat Chrysler, Cummins Now Dealing With Diesel Allegations

A new lawsuit alleges Fiat Chrysler Automobiles (FCA) and Cummins intentionally misled owners of diesel-powered Ram trucks.

The class action case was filed earlier this week in federal court in Detroit by Hagens Berman Sobol Shapiro, a Seattle-based law firm. Four plaintiffs are named in the complaint, but the law firm is looking to bring thousands of other owners into the case.

It is being alleged that the particulate emissions from diesel-powered Ram trucks were greater than what the automaker advertised. The lawsuit suggests the trucks’ emissions caused catalytic converters to prematurely wear out, causing the trucks to burn fuel at higher rates.

FCA has said it is reviewing the complaint and does not believe “the claims brought against it are meritourious.” The automaker plans to contest the lawsuit vigorously. In addition, FCA is currently cooperating with a recall demanded by the U.S. Environmental Protection Agency (EPA) and California Air Resources Board (CARB). The recall involves the 2013-2015 Ram 2500 pickup trucks equipped with a 6.7-liter Cummins diesel engine. The agencies found that moisture can cause deactivation of the catalyst reduction system, resulting in excess nitrogen oxide emissions.

    This sounds like a good reason to cut off the cat, conv. and run straight pipes instead. It never should have been on a diesel in the first place.
