Earlier this year Fiat Chrysler Automobiles (FCA) was notified of emissions violations with its 3.0L diesel engines. After months of close collaboration between the EPA and California Air Resources Board (CARB), FCA announced it has been certified by both organizations, which means sales of the 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. The automaker said updates for the 2017 model year vehicles include modified emissions software, without any need for hardware adjustments. Further, the automaker stated there should be no impact on fuel economy or performance.
Fiat Chrysler said it will continue to work closely with the CARB and EPA to seek permission to use the newly adjusted software to update its 2014-2016 diesel Jeep Grand Cherokees and Ram 1500 pickups.
“The approvals announced today represent a significant step toward resolving the issues raised by EPA and CARB,” CEO Sergio Marchionne said in the FCA statement. “We appreciate the efforts of the agencies in working with us to achieve this milestone. 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
