General Motors has responded to a civil lawsuit claiming that it included a defeat device in its diesel-powered vehicles by saying the claim is baseless, according to a company statement.

A lawsuit filed on May 24 by the attorneys who sued Volkswagen claims General Motors rigged thousands of trucks so they would pass emissions tests, reports Reuters.

The class-action lawsuit was filed in federal court in Detroit on behalf of owners and lessees of more than 705,000 Silverado and Sierra trucks equipped with Duramax engines from the 2011 to 2016 model years.

"These claims are baseless and we will vigorously defend ourselves," according to a May 25 GM statement. "The Duramax diesel Chevrolet Silverado and GMC Sierra comply with all U.S. EPA and CARB emissions regulations."

The lawsuit was filed by several lawfirms including Hagens Berman Sobol Shapiro, which was involved in similar litigation against Volkswagen that led to miltuple-billion dollar settlements.
