Apparently, Chevrolet has changed the injector warranty. Anyone have to deal with this? Did you get the dealer to do the work?

How has it changed?

I got a brief explanation on the phone today. I'm going in tomorrow to see the plethora of documentation the dude (Art was his name) @ the dealership says he has for me. If I remember correctly, it didn't fail a high flow fuel return test or something of that nature. So because it didn't fail all the necessary tests it's not covered.

Ugh. Reading the injector warranty info on this site I see why I'm not covered. Does anyone have experience with getting this covered anyways?

Not all failures will meet the 7/200 warranty. I do belive the letter states the type of failure that is covered but would have to dig to find it.

My truck is getting injectors today. 2 of the injectors did fail this test. The service manager said the other 6 are 1 kpa away from failing. He said the failure was 158 kpa and below? Not very happy with this. I understand the procedure and guidelines but I dont want to have to come back. As far as the warranty, he said all 8 injectors have to fail simultaneously to qualify for the 7/200,000. That is what I understood. I am sure I will be corrected if inaccurate.

I'm dealing with this right now, Same thing some bad some good. I asked him "what about the lines inside the valve cover that your putting on and taking off a few times that will leak sooner or later."
He didn't have much of a answer for me. I understand that they the dealer doesn't want to do it if GM won't cover (pay) for it. I guess I'll be looking for a LLY top end. Soon to be a LBY.

I got my unfixed truck back from the dealer with some extra information. My fuel rail pressure was 160.0MPa, which is exactly what is expected. Because the pressure test passes they won't warranty it. However, the balancing rate for cylinder 4 is 7.2mm^3 in park, where 4.0 is the absolute max. Meaning, it's leaking but not in a manner they'll warranty. :mad:

I called GM today and they're going to contact the dealer. I'm highly doubting this will work towards my benefit but we'll see. If anyone has any advice to get GM to warranty this please, share it.

Wait till it fails to the policy or fix it on your own. I would try runnin some 2 stroke oil in the fuel and see if that helps any some say it does some say it dont. What you have to loose?

SteelFuser, when I had mine replaced back in Oct 08 they changed the metal lines that go into the valve cover. It took 2 weeks because they had to order these lines and wait for them to come in. Sorry to hear about all the woes, probably won't get any easier anytime soon with GM. Hope it helps.

#'s 1&2 in my sig should help.

the return rates are done mechanically i dont think they can positively tell which inj is bad if the return rate is to high they just did mine in feb all 8 not one cent out of my deep pocket and i dout all 8 were bad all at the same time

Does it matter if you are the original owner to get the dealer to fix it? Looking back to my car fax my truck hit the road in July of 2002 and this is when my time is up? 163,000 and no injector work that I know of from the previous owner who got it at 35,000

Warranty/Special policy/Recall follows the truck...not the owner. You also don't have to take it back to the dealer you bought it from.

just got mine back friday with 8 new injectors, service manager said only one was bad but GM replaced all 8 free of charge. If it wasn't for you guys on the Diesel Place I wouldn't have known about the special policy. Thanks everybody!

I just bought 8 new injectors and installed them myself, GM told me that I was not covered under the special policy due to the edge juice i have. the dealer quoted me 7,850.00 all together parts and labor. a buddy of mine had his replaced at the dealer and they charged him almost 9,000.00 after they quated him a price similar to mine. I told my self this was not going to happen to me. I baught the parts at the dealer at a price of 209.00 a peice and did the job my self. I can honestly say it was not that bad. no special tools are needed, the valve covers are two peice on gasket is rubber can be reused your prvrence and the other side is silicone, the hardest part is clearing out all the stuff around the motor to get to the valve covers. it took me a total of about 10 hours to do the work at a total cost of 2,200.00

$9,000 OUCH. Isn't a brand new motor $25,000 or so. That's about 1/3 the price for a small piece of the whole pie. I'm glad I pulled off my EDGE before I went in. That was the same thing I was worried about. They saw the EGT thermocouple but didn't say anything. Good thing you were able to do it yourself. I don't think I have that capability. BTW change your oil and filter after changing injectors.

For $5-7000 you can get a fairly low mile LLY with all the brain boxes and wiring and put an engine in that is easy to change the injectors. I would do that before paying the stealer 9 grand!!

Can they deny the repair at GM if you have the Edge on it? I thought all aftermarket stuff was legal.

They would have to prove that the edge was responsible for the failure. In most cases, they just use it as a bs reason so they do not have to fund the extended warranty. Slap the magnuson-moss act on it and they might think twice ;)
I would at least have removed the edge or any aftermarket power adder b4 you take it in.

What I was told by my old service manager is: with Edge and other programers they are being very critical with injector failures because most of these devices increase the fuel pressure thus increasing the chance of premature failure. I know that Edge incerases the rail pressure, but whether or not that contributes to premature failure, I don't know. This is what he told me the dealership was saying to people who brought engine related problems. He is retired and no longer works for GMC but I see him from time to time.

Better take it off if you're going to go for injector repair. I still haven't put mine back on since I removed it back in October 08.

yes sir you are correct in a way. from what I have been told is the edge products increase the amount of fuel being sent to the injectors from the injection pump. this was my argument to the dealer when I went in with the truck. the injection pump should be failing not the injectors themselves. the lb7 motor has become a pain in the ass for gm, what is actually hapening is the injector body is cracking and causing fuel to run down and in to the crank case as well as the faulty injector not geting a good spray. the next geniration DMX injectors where redone and there have been no issues that I have seen.

Hmm....I can see where you are coming from. At the same time; however, I would think that increased rail pressure from things like a tuner or a lift pump especially, would relieve strain on the cp3 trying to work as hard. The injectors on the other hand, I am not sure about. Mine failed and filled the crank case full of fuel, leaked all over the garage floor. Replaced ~ 15k ago and one injector is already starting to be out of spec. Imagine that. Ughhhhhh

Actually, they just have to prove the vehicle was modified to operate outside of factory parameters. A picture of the box is plenty for that. Then the burden of proof falls to the owner to prove the modification did not cause the failure.

Are you sure about that? Who told you? A gm representative? If so, they are full of bs.

yes I am VERY sure of that.

Yeah, imagine that running EFI live with all that extra fuel, HP, and torque. There are many, many, many threads on here of engine and fuel system related failures due to power adders and programs. Some diesels handle these well, but the Dmax isn't one of them.

Not so full of bs. If you go the MM act route, you will go to court and GM will go to court. They will have lots of lawyers and more importantly PHD engineers and scientists that will swear up and down that by changing the parameters of the engine controller to give more HP/ Torque or what ever, that you have been operating outside of the factory performance envelope and because of that YOU have put more stress on the engine directly contributing and/or causing the early failure.

Ok, now it's your turn -- what do you say to the judge? "does not!" ?? Well, that won't cut it. Better have a defense that stands up. Either way, win or lose, you will spend more on legal fees than having the stealer swap injectors over a holiday on triple OT.

Key word there is ENGINE, not INJECTOR. Furthermore there is evidence out that the injector failures are caused by the FICM (Fuel Injector Control Module) itself on the first generation duramax engine. If you look into this, you will see that after the upgrade of the injectors/FICM on the 2nd and 3rd gen engines the failures all but stopped. HMMM...odd? The fact that un-modified engines spit out injectors just as fast if not faster than modified ones is evidence enough for me to argue the point all the way to the grave.

Both of you are presenting a good argument. We are talking about a power adder here bottom line. Granted, it looks like an easy excuse to pinpoint the injector failure but what about the completely stock dmax's. Obviously that statement would not hold water in court either. Just a thought that could be studied. I know stock dmax's that have been on 3rd set of injectors less than 50k.

injector failures are another story,, my comment was just a general statement referring to the warranty and MM. If you mod your truck,, the burden of proof falls to the owner to prove a flaw/defect caused the failure and not added stress created by the modification. I don't really care but I do this as I've been involved in the process and don't want people misinformed.

But my key word was LAWYERS :p:

Don't get me wrong here. I'm not saying that program power adders cause problems. (and I agree that the LB7 version of the injectors are not very durable)

The point was that while the MM act gives you specific rights, to gain those rights you will have to spend far more $$$ on lawyers than it would take to just man up and pay for it yourself. If you want to play you should realize you may have to pay. Or if you don't want to pay, just wait until the warranty is out to play. Sadly, my stock LB7 is 6 months from the 7 year time limit. Still on the first set of injectors and still going strong. Dern the bad luck! Oh wait, that's a GOOD thing:D.

The injectors are fine...the cause of failure is something not in the injectors fault at all. However, I do agree with you...given the fact that the actual cause of failure is shrouded in secrecy and confusion it would cost you alot more in court than in the shop. If the true cause of the failure was to come out from a reputable source then it would be a different story.

My truck is at the dealer right now about a smoking problem. They are refusing to cover the #8 injector under the program because I don't meet all of the required criteria. Quite frustrating

Dam lb7 are had to do,it's a long day :eek: but it is going ok

Wow! $9000 for injectors; I thought it was about $3400. I don't have any aftermarket add ons and never have and not sure that would make a difference. That 7/200,000 warranty(if for real) will be up on my truck in a year. I would have liked to at least get 100,000 out of it before any major expenses. Looks like it makes more sense to get rid of it before it happens. Too bad because I really like my truck. I would be better off selling it or trading it in at that cost. And I only have 64,000 miles on it. Could be harder to get parts from GM in the future. This injector thing is depressing to read about, but I'm glad I can find out from this site.

Wanna see bad news about what can happen at a dealer? look at the lb7 section of DTR. There is a thread about rusted lines being reinstalled on new injectors. It happened at the GMC dealer here in Mobile.

Here they run about $4100 customer pay.
