Fiat-Chrysler Automobiles may need to prepare for a long wait as U.S. regulators continue to review its proposed software fix to 104,000 diesel vehicles sold since 2014.
Reuters reports a U.S. Justice Department lawyer said the process could take “weeks or months” before regulators decide whether FCA’s new software is an appropriate fix and it receives an approval. In FCA’s corner, a lawyer for the automaker said it is optimistic the fix will be approved to put the 2017 model year vehicles on sale—it would then use the same software to update the older diesel vehicles.
FCA added it does not believe the software fix would impact performance or fuel economy figures of the Ram and Jeep vehicles affected.
The EPA suspected Fiat-Chrysler was cheating emission tests in 2015 after the automaker failed to offer an explanation as to why certain vehicles were polluting at higher levels than permitted. Since then, FCA has been accused of using illegal “defeat devices.” Auxiliary emission control devices are legal, but they must be disclosed to regulators and the automaker must explain their purpose.
The U.S. Department of Justice has also filed a lawsuit against FCA after it surpassed a deadline and failed to produce a fix for the vehicles. FCA also faces more than 20 lawsuits from dealers and owners over the alleged excess emissions.
