 I own a 2003 gmc 3500 sierra with a duramax diesel engine. it is used recreational, and has under 30k miles, but is now 36 months old. this summer 1/2 of my fuel injectors failed and were replaced under warranty. i'm concerned there the rest of the injectors will fail, as has been frequently reported by owners sharing concerns on various online forums. i am additionally concerned that this failure will occur after my warranty expires. i would like to request that the injector issues be researched for 2003 duramax engines, and that a recall be issued to update vehicles with new injectors that don't exhibit the same flaws/failures, or request that the engine warranty be extended to 200,000 miles as was done on the 2001-02 models. the date of this incident is estimated. *jb

 Failed component 1: driving at slow speed, reduced power light energized and engines goes to idle speed with no fuel pedal response. failed component #2: exhaust manifold bolts in cylinder heads broken on both sides of engine, passenger exhaust manifold cracked, exhaust is loud with exhaust fumes in cab. depending on what is causing the fuel system failure and whether the cylinder heads have to be removed to remove the broken bolts, these repairs could cost thousands.

 Dt: the consumer owns a 2003 gmc sierra. the consumer stated he has been having problems with the fuel gauge, fuel pump, and fuel filter. the fuel gauge does not work, he has to constantly fill up his truck to make sure he has enough gas. it started at 38000 miles just out of warranty when it stopped working. he had the part estimated by a mechanic and it is going to cost around 700 dollars just for the part. he does know of other people with the same truck and the same type of problem. the fuel gauge reads completely wrong when he is on 3 quarters of a tank it will be empty.*jb
