Per a report from Car Complaints, the lawsuit alleges that 2011- through 2016-model-year Chevy Silverado and GMC Sierra pickups equipped with the 6.6L V8 LML turbodiesel Duramax engine are equipped with defective Bosch CP4 fuel pumps that are more fragile and prone to wear than previous CP3 fuel pumps. According to plaintiffs, the defective CP4 pumps can be destroyed by U.S. diesel fuel, which is allegedly “drier” than diesel fuel in other countries. The lawsuit alleges that U.S. diesel fuel does not provide adequate lubrication for the CP4 fuel pump. The lack of lubrication can lead to internal fuel pump damage and result in metal shavings that damage the pump, the fuel system, and the GM Duramax engine as well. This damage can lead to the truck stalling and losing power, and may require the vehicle to be towed to a shop, leaving customers with big repair bills. The lawsuit goes on to allege that GM was aware that the Duramax engines and related fuel pumps were defective prior to selling affected vehicles, but declined to notify customers. Rather, GM allegedly concealed that the defective CP4 pumps may be destroyed by U.S. diesel fuel.

CP4 failure, caused metal fragments to go throughout fuel system and tank. Entire fuel system had to be replaced and tank cleaned out. CP4 failed in the middle of my drive home, stalling the truck in the middle of an intersection. Luckily had enough momentum to roll and pull over to the side of the road.

While making a slow speed right turn, 5 MPH, after stopping at a busy city street intersection, the power steering turned off and I nearly struck another car coming from the opposite direction because I was unable to turn my vehicle out of the way even when I used all my strength to turn. I have experienced this problem intermittently, always while attempting a right turn at slow speeds. It has happened mostly on city streets and while attempting to make a tight, right turn into parking stalls. The problem was reported to my local chevrolet dealer but, they were unable to replicate the problem and stated they could not fix it for that reason in june 2019. I returned the truck to the dealership today, 7/1/2019, for another attempt to repair. Waiting for a resolution. This truck has 100,000 miles on it. ## VIN passed ## chevrolet silverado 2500 hd 2015 ##
