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.

They are refusing to acknowledge my rights as a consumer;I will not pay 23,000 for a truck that is inoperable...help!
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.
When I was driving down interstate the truck (2005 2500 hd diesel) suddenly started running rough and lost engine power. The ses light came on. I pulled to the shoulder and turned the truck off. When I restarted the truck the ses light stayed on, but the truck would run. It went about 2 more miles and did the same thing again. It had to be towed to the chevrolet dealership. The #7 injector harness had shorted and had to be replaced.
Fuel pump relay keeps going out. I have replace 4 relays in the last 6 months and the dealer had replaced the fuel pump about 6 months ago.
I have a 2005 chevy silverado with a 8.1 liter engine, I was turned down on my warranty because there was rust in the fuel rail. We took fuel samples and there was no water in the fuel tank, nor the fuel lines. So how did the rust get in the fuel rail and injectors. I did notice that the new rail that the gm dealer installed was stainless steel. When I bring it up the dealer nor gm will talk about it. This repair was going to be warranty but instead it cost me $1,145.50 dollars. This was the second time I took it in to the dealer. The people I bought the truck from said they would give me my money back, but now all their offering me is $218.00 I told them to shove it. This truck costs me $41,900.00 dollars! The last thing I want is this warranty company to tell me is no! The warranty cost me another 2,000.00 I can tell it isn't worth the paper it is written on. Please I am on my last knee, please help !
Driving home, injector harness failed on my 2005 chevy duramax. This is a common problem that gm should issue a recall on. I had to limp home at 15 MPH, this was after midnight around curvy roads. Lucky I was not crashed into. This is a very dangerous condition that some could really get hurt, and likely already have. Here is a link to morehttp://dieselplace.com/forum/showthread.php?t=169625. Thank you.
While driving on the highway at 65 MPH then to 35 MPH service engine soon light illuminated along with a severe reduction in engine power(limp home mode). The cause is the injector connector circuits on cylinders 2 and 7 are not fully supported near the connector and are more susceptible to terminal breakage from engine vibration.
Towing trailer on the i90 interstate. Sudden loss of power and unable to regain speed on high speed highway. Dealer diagnosed as "fuel filter" problem. Has happened on numerous occasions seems common problem with gm duramax diesels from 2003 to present. The sudden loss of power can be dangerous on high speed highways as speed is cut drastically and speed cannot be regained to make a safe pull over to the side of the road.
During a routine morning commute, I noticed the check engine light had illuminated. Immediately following the malfunction, I noticed a severe decrease in engine power and the engine started to vibrate and mis-fire heavily. I was in heavy traffic and had to pull off of the road to avoid a potential accident situation. I then shut the truck off, and re-started the vehicle to possibly re-set the light. The engine started and seemed to run smoothly again, but the light stayed illuminated. It was 7am, so I decided to very slowly drive to the dealership where I had purchased the truck. The technician performed a diagnosis, and found a hard code of p2146 insulate ficm. I was then told that the main fuel injector system wiring harness had chaffed on a factory installed bracket and that it would need to be replaced. I was then told that they did not have the parts in stock, and that I would have to wait for one week to have the parts replaced. In the meantime, the technician stated that he had "insulated" the harness, and that the light was out. He stated that I should be able to drive the truck without any issues, but if the check engine light comes on again and I also receive a "low power" message on the annunciator panel in the dashboard, that I must park the truck and get a rental vehicle until the parts arrive and repairs can be made. The technician stated that this would cause four of the eight cylinders to shut down and cause a lean engine fuel condition which could result in engine failure. As of yet, parts to be replaced within one weeks time.
Driving 50 MPH on road, I stepped on the accelerator pedal to accelerate and the vehicle engine light came on. However the vehicle would not accelerate it was spitting and sputtering and slowed down for a while . I pulled over to the side of the road and shut it off. After ten minutes, the vehicle was restarted, and light went out and it ran perfectly.
