Injector Warranty?

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!

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.
