“I bought my 2014 chevy k2500 durmax diesel 4x4 I bought it under the impression I was told it would get really good gas mileage and its horrible the salesman said the new requirements that GM done to the exhaust and fuel the gov. Required was to help on pollution and fuel mileage. This should be looked into the fuel economy is horrible.”
NHTSA complaint #11174540, filed 2019-02, 34 miles“While driving from michigan into new york to deliver an rv to a dealership my truck experienced a fuel deficiency and stalled while traveling on a highway. I first thought it was the fuel filter but that did not resolve the issue and in towing it into a service shop they determined the bosch cp4 fuel pump had quit due to metal shavings which resulted in the entire fuel system needing to be replaced. This cost me over $15,000. It's my understanding that this pump is not compatible with the fuel in the united states and there has been a class action suit filed in texas. …”
NHTSA complaint #11363503, filed 2020-10, 170,000 miles“Fuel injection pump name apart internally cracking case spraying fuel on hot engine while driving down road, also sending metal pieces through fuel system to injectors making them useless and needing replaced. The fuel injection pump is located on top of block in front of turbo which gets extremely hot, luckily didn't catch fire”
NHTSA complaint #11132452, filed 2018-10, 103,000 miles“The system that failed was the CP4.2. The Cp4 is a defect that has failed; in the failure it has been ground down and it pushed metal shavings through the fuel system and it has also clogged the injectors. The failure of this system left me in a hazardous position in the middle of the highway. I could not turn or break because there was no power to my vehicle because it was not getting any fuel.”
NHTSA complaint #11533530, filed 2023-07“Cp4 failure, left me stranded and cost me 11k in repairs. 69k miles on truck 6,427.40$ for the Bosh disaster kit. Plus additional fluids, gaskets, ect that are not included. And 3900$ in labor. This cost me little under 11k. I have full invoice at total performance diesel at 300 west robles ave, Santa Rosa. This really affects my life. And it’s a common thing for the cp4 pump. 7,500$ deposit and 2,698.38$ was my final payment.”
