General Motors faces serious charges from owners of Chevrolet Silverado and GMC Sierra pickup trucks that come equipped with 6.6-liter Duramax diesel engines.
Based on the case taken up by the Detroit Federal Court on Wednesday, August 7, the claimants suspect the corporation of selling cars in the United States in 2010 through 2016 that were not duly adapted to the U.S. diesel standards.
Apparently, North American diesel fuel is different from that used in Europe. Among other things, it has lower lubricating power and density, leading to air pockets appearing in the fuel pump and exposed pump parts experiencing excess friction. This leads to an accumulation of tiny metal shavings in the injection system, which allegedly causes the engine to fail in the long run. Furthermore, the engine cannot be repaired due to the complete degradation of the injection system and other vital components.
Currently, eight truck owners put their signatures under the claim, but the group believes tens of thousands of clients may be affected, including those who purchased GMC Savana and Chevrolet Express MPVs equipped with Duramax LML or Duramax LGH V8s in the period from 2010 until 2016.
