NHTSA Complaint #11484352 — 2016 CHEVROLET SILVERADO 2500

I purchased 2016 Chevrolet 2500 HD from the dealership. The truck I bought had the CP4 high-pressure fuel injection pump, which comes standard in all GM-manufactured 2011-2016 6.6L Duramax diesel vehicles such as the Chevy Silverado and GMC Sierra, and it is incompatible with U.S. diesel fuel. The pump was originally designed for use in Europe, where the diesel fuel is "dirtier," or more lubricious, than that of the U.S. Because of the heightened pressure that the CP4 exerts in order to increase fuel efficiency, it causes the pump to disintegrate on itself, as the pump's internal metal parts rub against one another generating friction such that metal shavings wear off and are dispersed throughout the high-pressure fuel injection system. This process begins from the very first crank of the Duramax engine. Once these metal shards have sufficiently contaminated the high-pressure fuel injection system, the CP4 fuel pump will suddenly and catastrophically fail — oftentimes while the vehicle is in motion — and become unable to restart. I’m now looking at a $11,000 repair bill. GM knowingly sold a truck with defective parts.
