Fiat Chrysler Automobile's U.S. unit was denied a quick escape from a lawsuit that accuses the automaker of rigging diesel engines with emissions control defeat devices similar to those installed in 11 million Volkswagen Group vehicles.
A federal judge in San Francisco ruled Thursday that owners of 150,000 Dodge Ram and Jeep Grand Cherokee models across eight U.S. states can proceed toward trial over allegations that software in their vehicles was designed to hide emissions up to 20 times the legal limit.
Fiat Chrysler promised in court to provide a fix for the vehicles.
The Michigan-based unit of Fiat Chrysler was the first U.S. carmaker to be sued after VW admitted to malfeasance in September 2015 and committed to spending more than $24.5 billion on fines and penalties including vehicle buybacks across North America.
The Hagens Berman Sobol Shapiro law firm in Seattle has filed similar complaints against Ford Motor and General Motors, along with their supplier Robert Bosch.
