San Francisco/Washington: General Motors (GM) Co was accused of putting defeat devices in its trucks to beat emissions tests, the sixth carmaker linked to diesel cheating scandal since 2015, when Volkswagen (VW) AG admitted to installing software to bypass pollution rules.

People who own or lease more than 705,000 GM Duramax diesel trucks filed a class-action lawsuit Thursday, claiming GM installed multiple such devices in two models of heavy-duty trucks from 2011 to 2016. The 190-page complaint is littered with 83 references to VW, and asserts that the environmental damage caused by each truck could surpass that of the German automaker’s vehicles.

GM’s cheating allowed its trucks to pass US inspections, even while they spewed emissions two to five times the legal limit under regular driving conditions, according to the complaint filed in Detroit federal court.

The lawsuit underscores questions about the credibility of clean-diesel technology.

This week, the US justice department sued Fiat Chrysler Automobiles NV, alleging violations of clean-air rules. Daimler AG is the target of a German probe related to diesel emissions, and French carmakers Renault SA and PSA Group are both being investigated in their home country. Bloomberg
