I really don’t know where to post this, so if the mods want to move it that’s fine with me. I have been buying GM cars and trucks my entire life and most of them brand new in the last 6 years. I have had very good luck with them all except for this last one I purchased. It’s a 2005 Chevy 2500HD Duramax Allison. I have had this truck back to the dealer 6 times for the same problem If I come to a stop and then take off the truck will only go 25 – 40 MPH and has very poor throttle response and if you floor it is just chugs. The last attempted fix was a new fuel rail and fuel pressure regulator, the truck was a the dealer for 2 weeks while they gave me a very dirty and striped down Saturn Ion to drive. This was in June. I called the GM 1 -800 number and they were no help at all, they just kept telling me they wanted to make me happy but did nothing nor did they offer to do anything to make me happy. Well a few months later now the problem is back again. The dealer told me when I picked it up last time they didn’t know what was wrong with it and just hoped it was fixed. Like I said above this truck has been in 6 times for the same problem and has gone only 4 months that it was trouble free as the longest period between dealer visits. This is my wife’s truck that she and my newborn drive every day and she has lost total faith in this truck.
What are my options? Will GM buy this truck back because they can’t seem to fix it? How and who do I need to talk to? Can or does GM ever offer extended factory bumper to bumper warrantees in cases like this?

I am just fed up with all of the driving to the dealer and taking time out of my life for them to only tell me that they don’t know what’s wrong with it.

Any advice or people to call would be greatly appreciated.

Thanks,

Roger Romain

 

This only happens after a stop? They should be looking into the fuel tank. There's probably something loose or floating around in there that shifts forward and plugs/restricts the fuel delivery. It only takes 2 things to make a diesel run, fuel and air.

As far as escallating the move towards the lemon law. Get a lawyer.

 

My wife had a 2007 grand prix lease that broke down 4 times within a few months of acquiring it. IWe would get it towed t the dealer and it would suddently not have a prob. Finally one time I had it towed and left it running on the truck. It sounded like the motor had rocks in it. Finally they tok me serious. They did a bunch of testing and sent it back to me "fixed" the next week it did the same thing. I called pontiac and told them what was going on. They called the service guy at the dealeship and got their side. To make a long story short, gm bought the lease back on the gp and swapped us for a brand new torrent. Mine fit into the lemon law so that gave me leverage. They get 4 chances within the first year or somehting to fix it.

They say that the only code the truck has is low fuel pressure, so the last time it was in for 2 weeks they put an entire fuel rail and fuel pressure regulater on it. It was fine from June until now. and now its back again.

 

I believe the lemon law covers the whole factory warranty. not just the first year. Im a gmc/pont. tech. sorry dont work on deisel's so cant really add any suggestions but al's suggestion sounds like a great place for them to start at this point. when we get a car like yours (really, a symptom like yours, no matter what kind of car/truck)we try to take it very seriously. if it can be duplicated, then you shouldnt have too many prob.s geting GM to buy it back. not like you'll get 100% refund or anytyhing, they give I believe a fair market value amount or something like that. what HAVE they tried so far? all those visits and you only mentioned the fuel rails/reg. being replaced. if it goes weeks on end w/o doin it, then it will be VERY hard to duplicate. and they better be paying attention when it happens. we got a thing called VDR or vehicle data recorder, that would plug into the aldl port and stay there. what happens is it constantly records all the engine data (or whatever data you set it up to monitor) and keeps like 12 min.s memory. so 13 min's ago would be lost while its recording the curent info. when the car acts up, you hit the button and it will lock in the data at the time of the problem occuring. you go back to the dealer and they can pull that info up on the pc and examine it for whatever has changed from the time it was running correct, to what its doin when its not running right. it also marks the exact spot where you hit the button. so they can go to it as the reference point of running correct before, not correct after button.

PM JP2002LS1. thats my buddy john. he's a lawyer, and can probably help you. you should get that ball rolling now, even if you do want to keep the truck. it will help make the dealer pay more attention to it. and, you can request a larger car then the ion. but sometimes that may be all thats available. but if there goin to have you truck for a long time, they should atleast be able to get you into something like a envoy if you set it up ahead of time.

good luck man. keep us updated and let us know exactly whats been attemted, replaced so far.

what about the fuel pump? thats such a classic thing to go bad, along with the inj.s(which used to be all one unit I believe). never replaced those things?

 

So far on the first attempt they just put a new program in the computer.

Then it was the fuel rail and fuel pressure regulator.

Then it was all new intake and turbo gaskets because after the previous fix there was a massive leak on the intake side of the turbo, My concern with that was dirt in the engine but of course they said it wasnt bad enough to let dirt in. but then after that the service guy said I hope you have all of your oil changes documented.

Thats whats been done along with them testing every thing they and GM could come up with.

Its also been back for the steering clunk they all have and the power door locks all stoped working.

Thanks

 

you need to search online for the copy of the mich lemon law document. There is also a limit of how many days your vehicle can be in the shop for the same problem. People at the dealership didn't wanna do crap for me. When I called Pontiac they took care of the problem really quick, and I was really happy how they handled the situation. The computer ended up being the problem with our grand prix. They just found it too late. If you are going to push the lemon law you have to get the ball rolling and submit the paperwork. Then, after the paper work is turned in they get one more opportunity to fix the problem. When i called pontiac I told them that we ended our other lease to get into a more reliable family car since my wife drives such a long distance to work and that the car is used to carry the baby. I also told I am not shelling out 300 bucks a month on the lease and it is unacceptable to me to have a pos car that needs to be towed every thousand miles and picking up my wife everytime the the car broke down. They don't want to go to court and have to deal with you. If you get your ducks in a row the buy back division will buy the junker back.
good luck

Mcdonald Pontiac GMC granted me a factory extended engine warranty (6 years / 100,000 miles) on my 2002 GMC 5.3 ltr. for the piston slap noise.

 

I have been taking it to Martin Chevrolet in Saginaw. I have been on the phone with the Chevrolet customer service people close to a dozen time and have had two separate case numbers. Those people just keep stroking me off and saying they want to make me happy and make me happy with my truck, but so far nothing. After pushing a extended warrenty they said that the paper work for that would be put in. The engine already has 5 years 100,000 on it but I bet that doesnt cover electronics so I am pushing for a bumper to bumper.

I can hire a lawyer for free at work, so I guess maybe Monday I should at least talk to one and see what my options are.

I dont even know what I would buy to replace it.

 

I would assume the dealer drained the water from the fuel. Is the truck smoking when you take off?

 

fuel filter has been changed, there wasnt any water found. The truck does not smoke at all. It used to smoke really bad when I would floor it but that was when we got it and it actually ran good.

 

If it's not smoking at WOT then it's not getting enough fuel.

 

no ***** or black smoke at WOT.

 

Fuel, compression, and air. Assuming the fuel delievery is good and the injectors are good. Then what about air - I believe the duramax uses a variable vane position turbo with a position sensor. I not familiar with GM Trouble codes or the conditions in which they set. Though I wonder if the turbo is sticking and not giving you boost at WOT from a stop. Does the truck have a boost (psi) gauge? What kinda of boost does it build? Might try some of the diesel forums. I'm sure someone there has had the same issue and could probably give better help.
