Silverado 3500 8-cyl Diesel

  • 56,000 miles


Driving down the road and truck just starts stalling out. Got it to the Ford dealership who says there is rust in the tank and the fuel filter is full of it. This is a safety issue as I was barely able to get off of the road. These trucks need to be recalled for the fuel tanks. I've had vehicles that have never had problems like this with the rust. They at least need to be checked out.

Silverado 3500 8-cyl Diesel

  • 42,000 miles
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.

GM had a injector problem (recall ) in 2006. They replaced mine on Sept,27 2006. On May 21 20013 I had the same problem in which GM conveys they can't fix it again. The mileage on may, 21 was 84362, just about how long the others lasted. I was told from my local GM dealer that they are several other owners with this same problem (thousands). I just waited to pass my grief along to let someone else know how you are treated by one of the companies that we bailed out with our monies.

Silverado 3500 8-cyl Diesel

  • 36,273 miles


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.

October 2006 I received this letter from Chevrolet. We want you to know that the fuel injectors in some 2003 model year Chevrolet Silverado vehicles, equipped with a 6.6L duramax diesel engine, may require replacement because of high fuel return rates due to fuel injector body cracks, or ball seat erosion, or high pressure seal extrusion. Symptoms of these conditions include illumination of service engine soon (ses) light, low engine power, hard start, and/or fuel in the crankcase. This is not a recall. Do not take your vehicle to your Chevrolet dealer as a result of this letter unless you believe that your vehicle has the condition as described above. What we have don: General Motors is providing owners with additional protection for the fuel injectors. If this condition occurs on your 2003 Chevrolet Silverado within seven (7) years of the dateyour vehicle was originally placed in service or 200,000 miles, whichever occurs first, the condition will be repaired for you at no charge. On 29 October 2007 my wife took the 2003 Chevrolet Silverado equipped with a 6.6L duramax diesel engine to the Chevrolet dealer the injector leaking. The truck engine warranty was void and I was charged $2218.63 for the repair and the Chevrolet customer service representative told me they were denying it due to the excessive mileage. The truck had 108,880 miles on it and should be with in the additional protection letter. My invoice had note has banks 6gun system on truck. Engine warranty void! the banks manufacturer told me that any equipment that was installed does not effect the fuel injectors and it was already a problem that General Motors had sent in the letter in October 2006. I asked for some kind of diagnosis information or other proff that the banks system caused the problem and was denied any information.

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.
