2014 Ram 1500 EcoDiesel, Bear Mountain, May 2014 Enlarge PhotoFederal regulators gave final approval to Fiat Chrysler Automobiles to resume sales of diesel-powered Jeep Grand Cherokee and Ram 1500 models in the U.S., the company announced Friday. In the statement, FCA said it was working with the EPA to produce a software fix for 2012-2016 diesel-powered Jeep Grand Cherokee and Ram 1500 models. In May, FCA announced it would file for the certification after those models were pulled for sale early in 2017. Government officials said the diesel models polluted beyond legal limits, which FCA denied at the time. The automaker said the modified 2017 models didn’t require any additional hardware and would achieve stated mileage figures.
Jeep and Ram Diesels Earn Emissions Certifications
The automaker said updates for the 2017 model year vehicles include modified emissions software, without any need for hardware adjustments. Ram 1500 and Jeep Grand Cherokee equipped with the 3.0L diesel are permitted to resume after holding sales since as early as May 2017. FCA was accused in January of failing to disclose engine management software that increased air pollution in over 100,000 diesel-powered 2014-2016 Ram 1500 trucks and Jeep Grand Cherokee SUVs. Earlier this year Fiat Chrysler Automobiles (FCA) was notified of emissions violations with its 3.0L diesel engines. We are anxious to build on this progress to make appropriate updates to the emissions control software in our earlier model-year vehicles.” Source: FCA
2017 Ram and Jeep Diesels Given the Green Light for Sale by EPA
The 2017 Jeep Grand Cherokee with the same engine is rated at 22 mpg city and 30 mpg highway. FCA estimates the 2017 Ram 1500 EcoDiesel’s fuel economy at 21 miles per gallon city and 29 mpg on the highway. With modified software, Ram 1500 and Jeep Grand Cherokee diesel trucks from the 2017 model year finally have been approved for sale by the Environmental Protection Agency (EPA) and California’s Air Resources Board (CARB). Still unknown, however, is the fate of some 104,000 Jeep Grand Cherokee and Ram 1500 diesel trucks from the 2014–2016 model years that have been accused of using defeat devices. That means the vehicles emit what the EPA defines as a harmful level of nitrogen oxides, or NOx.
