Pickups Chevrolet Silverado & GMC Sierra Chevy Silverado and GMC Sierra Duramax Diesel Questions

| I have been arguing with GM about a cracked piston. In their service memo ID 2347464 they are dowining using Aftermarket Power Up devices. This includes a bunch of units that can harm the Izusu motor. They claim that all (at least the dealer I am working with) will harm their engine. The fact is that on pages 10 and 11 in their bulletin, they make reference to a (only one) cracked piston is due to an injector malfunction. My truck had one cracked piston in one cylinder that they first diagnosed as a bad injector in that cylinder. Now they are saying that the injector is ok and they are going to re-use it in a remanufactured motor. I feel they are trying to blame my Banks unit for an engine failure they are responsible for at a cost of $11,000.00. I have confronterd their service department, Banks and the BBB to resolve the issue. I have run the Banks unit for 4+ years with no adverse affects as I pay close attention to the monitor. It is important to know the duramax has 85,000 miles but has been emacuately maintained and cared for. I think we need to question some of their extened warranty policys and make sure they are dealing square. This is not a dis to the manufacture but a local problem. The minute they see a third party device they immediately discount any type of warranty. As long as they are used properly they can be useful. If they are affraid of the capabilities of the engine, they need to source something other than Izuzu. Kent | |
| I have a 2004 Sierra Duramax Diesel and have had some pretty bad luck. First sign of problem...I thought I ran out of fuel, but the fuel gauge showed I had over 1/4 tank. I called the tow truck and they said they would bring me diesel. Before he added it to the tank, I asked him if he was sure it was diesel, and he said yes that he had to make an extra stop at the gas station to fill the gas can. After priming, I was able to drive it home (3 blocks). I called the GMC dealer to have it serviced, and I drove it the next morning about 10 miles. It seemed to run fine even on the freeway. They informed me that afternoon that the fuel pump went out. They drained the tank and replaced the pump. They could not get the truck to run after that. After 5 wks of being in the shop, the service person I was dealing with called me from his cell phone and informed me that phone calls were taped, so I needed to talk to him on his cell phone. He asked me if I happened to put gasoline in the tank. I told him NEVER. I said his tech must have done it when they refilled the tank because it was obviously running when I dropped it off. Long story short...I've had my truck back for a year now and it's been running like crap ever since. It's been in the shop at least 6 times since that incident. When they so called fixed my truck, they said they had to replace the injectors, glow plugs, fuel pump, flush out the entire system, blah blah blah....it ended up being $6500 to repair, but he somehow was able to get my warranty to cover everything. All I had to pay is the $100 deductible. My truck is once again in the shop after just getting it back a few weeks ago for the fuel sensor going out. Now they said they need to replace glow plugs again, and there is an oil pan leak between the engine and transmission and they need to replace the oil pan gasket. To get to that, they said they need to remove two cross member plates, one is a factory part, the other is an aftermarket part which will not be covered by warranty to remove. Does this sound normal? I know I'm a girl, and don't know alot about diesel trucks, but is my truck ruined forever from them screwing up? I am frustrated and don't know what to do. | |

I have an '04 Sierra 3500 Crew Cab with the 6.6 Duramax and Alison trans. I have experienced a new problem with white smoke coming frmo the exhaust after the truck idles for a few minutes. When it is running sitting still and then drive off, the smoke pours out of the exhaust leaving a smoke trail behind me. The other morning when I hooked up our fifth-wheel RV, the truck was making clouds of white smoke out of the exhaust. I have checked both the oil level and antifreeze levels and both are okay. Ant help/advice would be appreciated.
