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, 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.

TTT


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.
