Other Fuel System Fuel Injection System problems of the 2012 Chevrolet Silverado 2500

Bosch cp4. 2 fuel pump malfunctioned and contaminated the entire fuel and injection system with metal shavings. The truck engine stopped while traveling at 50 mph on a city street and left me with no power steering. The entire fuel system needs to now be replaced and not covered by the manufacturer. Repair bill of over $7,000.

I was driving down a highway road when my vehicle abruptly lost power, I received a warning from my dashboard saying fuel filter needs replacing and subsequently lost engine power which resulted in no power steering and no brakes. I was able to keep the vehicle under control and got it to the side of the road before it became dead. After getting the vehicle towed to a garage it was determined that the cp4 fuel injection pump had failed resulting in fuel being starved from the engine and the result was the engine shutting off. The repairs alone for this single failure are $8550 because this pump has fouled all the fuel injectors and regulators in the fuel system. Most importantly though, I was fortunate enough to be in a position on highway where I had no traffic behind me, and on a relatively straight road where I was able to get to the curb before it become a bigger problem. From what I have found this is becoming a common problem on all of the duramax 6. 6l lml engines utilizing this type of fuel injection pump and gm needs to recall these systems and repair them. I do not have the repair invoice yet because the vehicle is still being repaired but will be happy to supply it when I receive it.

Vehicle would not start. When they put it on scope they found that the fuel rail pressure was to low. They found metal shavings throughout the fuel system as if a part was coming apart from the inside. They had to replace entire fuel system from pump to injectors plus all the lines and injection pump. This vehicle is 2 years old.
