General Motors is being sued for allegedly rigging diesel engine versions of its Silverado and Sierra HD vehicles to pass emissions tests.
The suit was first reported by Bloomberg.
Shares of GM fell 2.7 percent on the news.
About 705,000 owners of GM Duramax diesel trucks are plaintiffs in the class-action lawsuit filed Thursday, according to Bloomberg.
The suit alleges GM placed multiple emissions test defeat devices in the Sierra HD and Silverado models of heavy-duty trucks, made from 2011 to 2016.
The 190-page complaint references VW more than 80 times, and says the GM models may have caused more environmental harm than those of the German automaker’s vehicles, according to Bloomberg.
Several automakers have been accused of cheating on diesel emissions tests since 2015.
