Recently, my vehicle has had a hard time starting. I took my vehicle to the local Chevrolet dealership to have it inspected/diagnosed. I was informed that my fuel pump/filter combo as well as all the injectors needed to be replaced and would cost me just under $6000 for the repair. It has come to my attention today after researching that this is and has been a known issue to the point that GM issued a service bulletin to repair this problem and modified the bulletin to extend the time frame and/or total mileage, but that time extension has expired before my vehicle developed the same issue that the bulletin addresses. With such a wide spread problem such as the nature of this magnitude, why does this not fall under a mandatory recall from NHTSA? I use my vehicle for only weekend recreation, and as such, I only have 42K miles on my vehicle, and for an engine that I paid a premium for, I think that it is just plain wrong to expect to pay such an outrageous bill for an engine that is advertised as a 'tough, long-lasting engine'. NHTSA should force GM to address this issue, because there are many like me out there, and I truly believe that is a safety issue for the people like me that own these vehicles.

On April 19, 2012, the Chevrolet dealership advised me that two or three of my 2003 Chevrolet Silverado diesel fuel injectors, part# 97729095, needed to be replaced and recommended all eight fuel injectors should be replaced at a cost of $5,260,18. I asked if this repair was covered by Chevrolet and the dealer representative said my truck did not qualify because the time limit had expired. He said if the vehicles fuel injectors had failed within the first 200,000 miles or within the first seven years they would have replaced the fuel injectors at no cost. On that date, April 19, 2012 my vehicle had 36,273 miles and was 9 years old, I asked why the dealership hadn't notified me of this problem and they said it was not their responsibility to notify me and refused to replace/repair the defective fuel injectors.

While the vehicle was parked the driver noticed a brownish liquid leaking from underneath the vehicle. The driver took the vehicle to the dealer, and the mechanic determined that the filter and other parts needed to be replaced due to corrosion. (the VIN number entered per consumer, did not match the vehicle given)

At least one fuel injector failed on my 6.6, duamax. 3700 miles out of warranty. Can not replace just one. GM says to replace all. No way to test injectors. Injectors are not stocked because of high price. Down 13 days because parts not available.
