Plaintiffs in an ongoing securities fraud class action suit against Fiat Chrysler Automobiles over emissions violations faced a setback on Tuesday. U.S. District Judge Jesse Furman of the Southern District of New York granted defendants' motion to dismiss new allegations of fraud by the international automotive company.

The latest theory offered in the suit seeking class status was sunk by “general claims,” “vague statements” and “unremarkable fact[s]” that didn't hold up under a conscious recklessness standard, Furman found.

The securities suit, initiated by plaintiff Victor Pirnik, was first filed in September 2015 after the FCA recalled over a million vehicles over safety concerns. In the expanded allegation in the plaintiffs' third amended complaint, defendants, including FCA's CEO Sergio Marchionne, are alleged to have misled investors after California and federal environmental regulators issued a violation notice in January 2017 for failing to disclose software that could alter emissions outputs in recent diesel versions of Jeep Grand Cherokees and Dodge Ram 1500 trucks.
