I have a 2002 Duramax with 106,000 miles on it. I noticed the tell-tale white smoke coming from the exhaust and from the smell I could tell it was diesel and not water. I immediately suspected the injectors after all that I had read on this board.


I took it into the dealership and they ran a few tests and concluded that 3 injectors were bad. Without any hesitation they told me it was covered under the new extended warranty and all eight injectors would be replaced with the 3rd generation injectors. All this without any fighting or even showing them the letter from GM (extending the warranty on the injectors).


Thanks to all of you that have dealt with this issue since the early detection of the injector problems and the pressure put on GM to resolve this problem equitably.

Sounds like a dealer to stick to!

Good luck with it.

I am confused on the warranty thing on the 01' & 02' models. It looks like the letter gives you an additional 200,000k mile warranty if your injectors go out before your 100,000mile warranty.


But, from what I read the this post with your truck having 106,000 on it. That I am covered until 300,000 even if my injectors don't go out until say 150,000k.


Am I reading this right?


Thanks, Neil

The new warranty will extend your coverage on the injectors only out to 200,000 miles from the original in-service date. It doesn't giver you an extra 200,000 miles on top of what is on your odometer right now.

The new warranty is GM's admission that they #$%#$%#$^ up.

Took them three years to admit it. Personally I think they should design and test a fully reliable injector and replace them all. Instead the customers are driving time bombs and they will replace them as you break down. SUre it's free... but who wants to deal with it?Edited by: hoot

Are you saying Recall ???


I think the problem is intermediate at worst .... Your right who does want to deal with it ...I'm hoping need be they'll have it mastered by the time I get there ...


Do you think it's a manufactured defect or filtered fuel issue still ...


Seeing that they have changed the injector style and not opted to add or change filtering capabilities one might assume all the hype in adding finer filtering may just extend the inevitable ...


What's next GM endorsing secondary filtering like additive is now ??

Agree 100%.


If nothing else, change their new "extended injector" warranty to 200k miles period. Why the time limit? If they want to impose a time limit (7 years), then replace all the injectors now.

How does one now if an injector goes bad? Looking over my truck history (I bought with 68K Miles) and 3 injectors were replaced. What do I need to be aware of with that? http://www.dieselplace.com/forum/smileys/Rock On.gif

In my case, I noticed that my truck seemed to be running rich. The exhaust smelled like raw fuel and there was a light amount of white smoke (mostly at idle). I knew it wasn't coolant because the exhaust didn't have that sweet odor associated with coolant leaking into the cylinders.


After reading many posts here, I concluded it was probably an injector problem. This was confirmed by the tech at the dealership after he hooked my truck up to the Tech II analyzer. The specs of three injectors were outside of the normal range. GM requires that all 8 injectors be replaced if any failures are detected.

I noticed white smoke the other day at idle after pulling my 5er. Having read the above statements I wonder if it could be injectors. I was told to put the truck under a load and pulling a #10K trailer one would think that is some stress. Will an injector throw a code or even make the service engine light come on or do I just go to the local stealer and tell them to Check for bad injectors???

http://www.dieselplace.com/forum/smileys/Angry.gifI agree G.M. should replace all injectors as a recall mine went out last week 62000.miles truck loaded with camper and kids.Lucky it puked 15 miles from home.Dealer is telling me 4-6 weeks for injectors he has one poor guys in the shop for 3 weeks now.How can I drive this thing with confidence?I have to say I don't feel comfortable driving this thing anymore.tick tock

Run a secondary fuel filter and a fuel additive. I think you'll be fine. Every truck make has their problems. When my injectors went bad, I immediately got a SES light and a noticeable loss if power. Plus the bottomside of the truck and the rear end was covered with diesel/oil mix. Was coming out of the breather tube on the bottomside of the motor. Don't worry, you still have the best truck out there.

I have noticed some decrease in my power as well. HUMMMMM should go on Monday and have em check it out. How long will it take to tell if it is the injectors?


Ben http://www.dieselplace.com/forum/smileys/Rock On.gif

They diagnosed mine in a few hours. I dropped it off around 10am and They called around lunch. M SES light came on. I guess they checked the code.

Thanx. Will take it in to have it checked. I do think this site is tops and I tell all Dmax owners about it too. Thanx Dmax power007 for yer help. R the Bilsteins easy to install?


Ben http://www.dieselplace.com/forum/smileys/Rock On.gif

blnagel, this site rules all others. It only took me about 45 minutes to put my Bilstiens on. Weeeeeellll worth the money!

I called the dealership this morning. They are ordering 8 new injectors for my truck. I had 81,800 miles on the clock. Mine just started acting up all of a sudden. I just had an oil analysis done at 80k miles and nothing was abnormal!

Good luck getting injectors now.Mines been in the dealer for 10 days now and they have no idea when injectors will be available.they say it is a national back order I called G.M. hotline and raised heck and I was told that bosch was producing 20,000 injectors a day and they expect the next batch to be into the warehouse the week of july19-23 and they did not think my back order would be part of that shipment.What the heck do they expect people to do. Heck this is my work truck! My big question is are these new injectors 2nd or 3rd or 4th generation designs? and have they gotten them right this time.Kind of hard to have much faith driving these things now.Damn they don't even give you any warning one minute its fine the next your limping down the road

This should be a recall not a warantee extension.http://www.dieselplace.com/forum/smileys/Cry.gif

Before I took my truck in, I had heard that there was a real shortage on these injectors. The dealer that did the work on my truck didn't have any in stock, but was able to get them the very next day. This was just a couple of weeks ago.

I've got a truck down for going on three weeks now with fuel in oil.. no parts


No idea when they will be in, but the guy uses his truck for work, he is driving one of our 04 Sierra 1/2 tons for a loaner... Judging by what his dmax looks like, our loaner will not look good

I does suck just waiting for the day the oil pan gets washed out with diesel. I does not inspire a lot of confidence in ones ride.http://www.dieselplace.com/forum/smileys/Cry.gif I would like to get mine changed out before they fail and save the bottom end of my motor.

Blue, I have never seen one fail from washed bearings, remember, diesel fuel is actually a good lubricator

I hope they go bad on the day I plan to change the oil. I would hate to spoil a new load of oil and filters.

Does anyone know what "generation" injectors went into the '03's? 'Cause of what I've read at this forum, I'm now using secondary pre-oem filtration and an additive to avoid this problem all together (and to think, when I purchased the truck, I told my wife "...honey, this thing will run for 400k no problem!")

If one were to use (borrow) a Tech-II to measure balance rates and at least one injector is found to be out-of-range, does this mean GM will replace all 8 injectors now? Or do we have to wait until we get the excess smoke or crankcase full of diesel fuel?


Would this be a way to know if injectors are about ready to go and possibly flood the oil pan with diesel fuel? Or is this a separate issue? I am just thinking this might be one way to know there is a problem before it happens and possibly get GM to replace the injectors before the crankcase fills with diesel.


I like that GM finally acknowledged there is a problem but I don't like how they are handling it either. Anything to save money I suppose.


As for national backorder on injectors, have they ever not been on national backorder?


Thanks,


Tim

balance rates are only a reference it seems. Yes, they point to a potential problem... but not always a meaningfull reading.

Eric,


Thanks for the info.
