FCA Files for Diesel Vehicle Certification in the U.S.

FCA has filed for diesel vehicle certification with the Environmental Protection Agency and California Air Resources Board in the U.S.

Fiat Chrysler Automobiles announced that it formally submitted an application for diesel vehicle emissions certification to the Environmental Protection Agency and California Air Resources Board for its two diesel vehicles, the EcoDiesel variants of the 2017 Jeep Grand Cherokee and 2017 Ram 1500. The filing indicates that FCA will update its two diesel-powered vehicles to address the EPA’s recent accusation that the automaker didn’t disclose engine management software that increases emissions.

In order to remedy the issue, FCA is installing updated emissions control software on the vehicles in question. Part of the filing also includes asking permission from the EPA and CARB to install the software on 2014-2016 diesel models. Once the approval has been given, owners of 2014-2016 diesel-powered Grand Cherokees and Ram 1500s will be able to receive the new software update through FCA’s dealership network.

FCA says it believes its fix will address regulators’ concerns regarding the emissions control software in its diesel-powered models. The automaker also says that the new software should improve emissions without affecting efficiency and performance.

Earlier this year, the EPA accused FCA of not disclosing the presence of an auxiliary device in its diesel-powered vehicles that allegedly increases nitrogen oxide emissions during normal driving conditions. The automaker has since been working with the EPA and CARB to find a viable solution.
