GM Sued Over Diesel Truck Concerns

 Aug. 9, 2019—A lawsuit claims General Motors allegedly knowingly sold diesel-powered pickup trucks that cannot run on U.S. diesel fuel without damaging the fuel system and engine, as noted in a report by CNET.

The lawsuit, filed on behalf of eight plaintiffs, claims the trucks and vans feature Bosch-designed fuel pump systems that do not work with U.S.-spec diesel fuel. Specifically, U.S. diesel fuel is thinner and provides less lubrication, which in turn creates air pockets. When such air pockets form in the fuel injection system, metal directly contacts metal. The alleged end result is metal shavings pumped into the fuel system and engine and, as a result, major damage.

The specific vehicles named in the lawsuit reach back to the 2010 Express and Savana vans. Chevrolet Silverado 2500HD and 3500HD pickups from the 2011-16 model years are included in the filing, as are GMC Sierra 2500HD and 3500HDs from the same model years.
