2005 Chevrolet Silverado 2500: check engine light

Filed Jun 20, 2016 · Brakes, Fuel system · 128,200 miles · VA

Brake lines rusted out prematurely and burst, causing loss of braking ability. Had to replace every brake line on the entire truck, for they were all extremely rusty. 2 months later my fuel line also sprung a leak due to excessive rust, causing fuel to spill, check engine lights, and hard starting. Both of these issues present major safety concerns, and unfortunately are extremely common with these trucks.

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.

This truck is equipped with the 6.0l vortec v8 engine and has developed an exhaust leak on both sides of the engine at the manifold gaskets! The leak is from the ports where the bolts securing manifold to cylinder head are broken! Gm is well aware of this issue, does not want to recall the issue or warranty the repairs. There are thousands of complaints from owners of gm vehicles with v8 engines including the 4.8l, 5.3l, 6.0l engines. This is a problem in many of ways, most importantly that toxic exhaust fumes are emitting from under the hood and can enter the cab of the vehicles! Inspection laws require that exhaust fumes exit the vehicle behind the rear wheel! The other problems include the fact that this leak will affect readings taken from the upstream oxygen sensors and can therefore cause check engine lights for catalytic converter deficiencies to system lean conditions. Also having an exhaust leak will fail safety inspections and emissions testing. Gm is violating epa laws by allowing this to go on! This particular vehicle is past due for inspection and emissions as we are a pennsylvania resident and I cannot afford to have this fixed at a dealer!

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.
