A new lawsuit claims General Motors knowingly sold diesel-powered pickup trucks that cannot run on US diesel fuel without damaging the fuel system and engine.
Specifically, the litigation surrounds Chevrolet and GMC trucks equipped with the 6.6-liter Duramax turbodiesel V8 engine, as well as Chevrolet Express and GMC Savana commercial vans.
The Detroit News reported on the lawsuit filed on Wednesday in a Detroit-based federal court where plaintiffs provided alleged details of the faulty systems.
The lawsuit, filed on behalf of eight plaintiffs, claims the trucks and vans feature Bosch-designed fuel pump systems that do not work with US-spec diesel fuel.
Specifically, the lawsuit claims US diesel fuel is thinner compared to a thicker blend sold in Europe.
Knowing the fuel is thinner, it provides less lubrication, which in turn creates air pockets.
