Filed Sep 14, 2012 · Fuel system · 152,000 miles · CO

While driving along on a mountain road, the check engine light came on and I suddenly lost power to maintain speed. The truck went into what is commonly called "limp mode", unable to make any more than 10 MPH. I discovered that a problem common to this make model year occurred. The wiring harness to the fuel injjector (diesel) shorted to injector #2 and #7. The computer shut down the fuel to that cylinder bank as a result of the short. This is commonly spoken of in internet blogs and gm has a tsb for a repair. It is tsb 05-06-04 047b (I believe). It calls for replacing the wiring harness as it has become worn due to improper engineering and placement. The parts have been updated to prevent this. It costs $576.00 to repair. I believe this should require a recall. What would have happened to me had this occurred on a highway at highway speed. Unable to maintain any speed, ii could have been involved in an accident or cause one.

On january 23, 2009, the #7 injector harness shorted and had to be replaced. On march 21, 2009, the ses light came on and the truck sounded different running, but did not lose power. Diagnostics showed problems with the fuel injector module. On march 22, 2009, the ses light came on and the truck started running rough and lost engine power (just like it did on january 23). The truck had to be towed to the chevrolet dealership again. This time the #2 fuel injector harness had shorted and had to be replaced. With both incidents, the fuel injector harnesses were replaced with a new harness that has a 90 degree plug and longer wires. This is not covered by warranty and costs $400+ to replace each one. Within 2 months and 2500 miles both the #2 and #7 fuel injector harnesses have shorted and had to be replaced.
