Injector Warranty?

Someone (Inspector perhaps?) suggested a 300,000 mile warranty on the injectors. Anyone else heard this?

Mike (in Spain this month)

Wasn't me. I too saw a blip on the extended warrenty and wondered of its validity thats why I looked at this your post. Would be nice wouldn't it?
Denny

Denny, Yea, it would be nice. If you hear any more on this would you please post it in big letters? The connection over here is slower than a ten month gestation.

Mike :rolleyes:

John Deere,
You said a Dealer told you of a 300,000 mile warranty... Who was the dealer?

Mike

I have seen in some posts that people are getting 7 year warranty's on their injectors. How do you get this and is it before you had injector problems or after? They are replacing my injectors now. Can I expect (or beg) them to extend the warranty on them to 7 years?

rsgs,

IIRC, some 01 and 02 ownwers have received letters from GM stating that they have an extended 7 year 200k injector warranty. I also remember reading somwhere that the new warranty may apply to 03's on case by case basis (or something like that).

The new extended fuel injector warranty is a no-cost extension - meaning no deductible. All of these engines come with a factory 5-year or 100,000 warranty, regardless. Any other engine or fuel injection component problem will be covered after 3-years or 36,000 miles with a $100 deductible.

I had a talk with my dealer today about this issue. He is a very reasonable fellow and he agrees that the extended warranty is just what GM should have done when these problems started becoming evident. As a dealer, it makes his job a lot easer. His private belief is that GM got a bad batch of injectors somewhere in the parts flow, and that is the reason most owners are not having, and will not have any problems with injectors.

Then we talked about engine damage associated with fuel in the oil. He also agrees that when there has been any significant amount of fuel in the oil -- and the truck has been run for even a modest amount of time with that contaminated oil -- that the entire engine should be replaced. While he agrees, his contacts with the higher-ups in GM on this issue have produced an absolute "NO". GM told him it will not replace engines in this situation, despite the logic of it.

There can be no question that bearing and other surfaces subject to friction will not be lubricated properly if the oil is thinned by fuel. How can GM hold to rigid lubricant specifications for their engines, and at the same time say that fuel-contaminated oil is not harming the engine?

I haven't had a problem with my truck ('01 K2500) along these lines, and perhaps (hopefully) I never will. But for the sake of all of us -- and particularly those poor folks who drove around for a while with a crankcase full of diesel -- the engine replacement issue should be elevated to the same level of importance as the injector replacement problem was.

Thanx for the info guys. I did not know about the 36 month/36k miles 'extended' warranty. Now I wonder if the life expectancy of my engine has been shortened because of this. I may have drove 20 or so miles after the injector(s) went. When injectors go, do they go like mine did? All of a sudden. Or do they fail over time, dumping fuel in the oil the whole time?

As I said, I haven't had any injector problems. But in the instance the dealer told me about, by the time the owner noticed enough of a problem and got the truck in, the crankcase was completely filled with an oil/fuel mixture. This surely had a high probability of doing some damage to the engine!

The good news is that if you are fairly confident you only put 20 miles or so on the truck with fuel in the oil, the potential for damage would seem to be limited. Since I'm not an engineer, lubricant specialist, or anything other than a common-sense guy, my guess on this is just that. But if I were you, I would not be terribly worried about the long-term impact in the situation you describe.

Dr. Lee might have a totally different take on this, given his background in this area. Any comments, Lee?

What are the symptoms of an injector failure??? How does one know that there is fuel leaking internally??? I have an 01 and have received my notice of the extended warranty on the injectors, but I don't really know what to keep an eye open for.....

AB_DURAMAX: Check out my other post "Help... I'm smoking". I drove to work and everything was fine. I stopped for coffee, got back in the truck, started it, and it just bellowed dark black smoke and sounded like it was running on three cylinders. As I accelerated, it smoothed out and the smoke decreased some. No SES light or anything. I stopped by the office, and then went to the dealer. Just for s&g's, I changed the fuel filter in the parking lot, hoping for a miracle, but... it's been there since last Thursday.

Well take it for what it's worth. I had fuel dumped in my engine 4 times from injector problems. The last time the engine just let loose. I was in Tx. at the time & had to replace the engine. Oil was full of shavings,bearing material, even though GM said the previous 3 times diesel in oil was "NO PROBLEM". I seviced this truck on a very rigid schedule.I had 282K on the truck. When the first problem ocurred at 215k (i think it was) dealer told me he had never had a cleaner engine (inside) with that amount of miles. I think these engines would go a lot farther if GM would ever get the injector problem fixed. But now I understand LLY's are having injector problems also. Whays the deal?

Thanks rsgs, that helps !!!

Many of us owners (2001-2002) have not received the
the "letter" advising of this extension for either
the injectors or the tailgate cables.

Does anyone know why GM is doing this seemingly random
notification?

I heard they were notifing people in stages.

Da Boy TG ;)

I am thinking about buying a used 2002 Duramax 2500HD. The truck has about 60K miles on it. My questions is, if the injectors fail after I buy, will they be repaired by GM for free even if I am not the original owner and likely will not have any paper showing an extension of warranty?

Thanks.

The injectors are warranteed for 200K, regardless of ownership. You do not need to show any paperwork. The VIN will tell them all they need to know. You may want to take the VIN to a dealer to be sure it is included in the bulletin. Some were not, but that doesn't mean it won't be covered.

and for a maximum of 7 years.

GM sent me a warranty addendum for the injectors.

Well, after having my fuel filter replaced due to a recall notice 6wks and 500mi. later I've noticed longer cranking interval before start up. I returned my 2003 Silverado DMax with 21000mi.and was called back about 2hrs later and told it was injector failure.He said that It would be covered under the Diesel Ext. Warranty with a $100 deductible. I have since seen past references on this site mentioning a Zero Deductible Extend Warranty on Injectors. Does anyone know if this is for specific years or where I can find the correct anwer to research this before I pay the $100 deductible?

Your injectors could be covered under one of three warranties. Because your truck is a 2003, the extended injector warranty may not apply. That warranty has no deductible. Your truck also has a 100K/5 year OEM engine warranty, which covers injectors, and has a $100 deductible, and the 3/36 B to B warranty. Your dealer may or may not be able to decide which warranty to apply, but you need to find out which they do apply. Of course, the 3/36 warranty has no deductible. If they apply the 200/7 warranty, and charge a deductible, you are being gouged. Let them do their thing, and settle up when it's done. Check the bulletin or policy #'s they reference on your repair order and compare with known policies. If they are gouging you, they are probably gouging others, and that should be taken up with GM customer service to put a stop to it, and get your deductible back, if you paid it. It's not uncommon for dealers (of any brand) to charge deductibles when they are not due. Problem is, most folks just pay them and thank the dealer, grateful to get their vehicle back in working order.

Another thing that happens is the dealer will try to "buy" your warranty service survey. They will usually offer an oil change or two to get it. Recently, I received a phone call from GM customer service. They did a survey for service quality, and one of the questions asked was if the dealer attempted to get my survey card. This is not an acceptible practice for dealers, according to GM. My dealer didn't ask for it, but did request I be sure to fill it out and send it in.

Just got the truck back from having the number 1 injector replaced. This is the 2nd one to be done in the last year. The dealer says they can't do them all because GM wants to see the Balance rate numbers out of spec before they will pay for it. The recurring symptom I get is a knock at idle and an uneven idle. That is what I had both times when a bad injector was found. (Number 1 and 7 have been done now.)
This time they had to replace a fuel return line as well because the bolts got rounded out. I know I didn't do it so that just leaves the mechanic!!!! To the dealers credit, I was given a rental car for two days and they changed the oil for free too. The balance rate on the latest one was 6.0 and they won't change it until it is reading more than 4.0 plus or minus, out of spec.:D :D :D

I picked up my 2003 Chev.with 21,200mi. after they replaced 8 injectors due to long cranking interval. They charged me the $100.00 deductible on the extended diesel warranty. My truck was 3 yrs. old on 5/15/06. They could not tell me why they failed so early and assured me that this was a rare occurance. I have changed the fuel filter 4 times since new and have not used injector cleaner per owners manual. I am at a loss as to what caused premature failure. Any thoughts or suggestions to avoid this happening again? Is this a poor design problem?

Can some one post a link to the 200,000 mi Injector Warranty for 2001-2003 lb7? Please?

check my hot start thread. My dealer said they don't replace 1 at a time because it always comes back later so they change out all 8 injectors. There was no cost to me for the injector pump or the injectors. 2003 w/75,000 miles.

I'm new to Diesels, and have alot of catching up to do! I have read about injector warranties for 01'-02' Duramax and am wondering what the heck this is all about? Can anyone tell me what was wrong, and what the symptoms were? How can I tell if this has been taken care of already? Is my 01' (69,000) still under the warranty? Thanks for any help!

Shed

PS I'm lovin this big black diesel! Can anyone give me info about maintenance issues I should look into with this truck? Just purchased about 2 months ago and want to keep her in top notch performance to pull my 5th wheel!:D

Hello Shed
I just had all 8 Injectors replaced under the extended injector warranty ,
the symptoms on mine were decreased fuel mileage - skipping at idle - fuel in crankcase and service engine light .
My dealer ( Hardy Chev. in Dallas Ga. ) didn't give me any hassle and did it in 3 days .
The extended inj. warranty is good for 7 years or 200k miles and it goes with the vehicle , your dealer could give you the history on it with VIN .
Mine had 92k miles when it went down .
I have been using Amsoil synthetic from front to rear since it was new .
I pull an 06 31' Sunnybrook that weighs about 12k loaded and it works great - on a recent trip to Va. I got between 10 - 12 mpg running about 62 mph .
I keep looking at the new ones but this one still works Great !!
Welcome Aboard

Thanks for the info! I will definately check with the dealer on the injectors. Were these injectors "bad" or was this just something offered in these years? I am not having a whole lot of trouble with the truck, other than a pesky "srvc. 4whl drive" light that comes on right after start up! Thanks for your input, and if anyone else has ANYTHING for me, please keep it coming, as I said I'm a novice and need all the help and knowledge I can get my hands on! Thanks again.
;)

The injectors are only replaced if they fail.

Your "svc 4x4" is an easy fix, usually. Check and reset the connector at the back of the button cluster. Easy to get to. Just pop off the IP trim and the cluster pops out after releasing the tabs. If it continues, the button cluster will likely need replacing. It isn't too expensive, IIRC. There is a possibility the motor on the TC has issues, but short of checking connections, it's not cheap to fix.

Hello all,
I had a friend who recently purchased a used 2002 Chevy 2500HD with 103,000. We have noticed that it smokes a little blue at idle, which makes me think that it is a fuel issue (injector balance, etc). It sounds fine and runs fine, just has a minor blue smoke at idle. My question is, I somewhat recall GM has had some update bulletins regarding warranty of the injectors on the early LB7 motor. Does anybody out there have the details of these revised bulletins and/or if this vehicle still qualifies for warranty with 103,000 miles on it?

Extended Warranty is 7 years, 200,000 miles. No deductible.

Thanks for the reply. So does this "extended warranty" apply for all LB7 motors or was it something the owner have to sign up for/purchase?

2001/02/03 LB7 Injector Warranty.

Jim

Thank you Jim.

I heard that this warranty was voided if you run bio diesel, is there any truth to this?

Thanks

GM approves up to B5. Higher than that, and you are on your own. The service manager can only deny warranty claims for stuff he knows about.
