or some other form of courtesy transportation is available and will be provided at no charge.
Dealers should refer to the General Motors Service Policies and Procedures Manual for Courtesy
Transportation guidelines.

conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained

Don't hold your breath,
just because you have this policy don't mean sh!t as far as being guaranteed GM will replace them for free if they fail.
My 2002 had white smoke and power loss 3.5 months ago, and GM states, "I'm sorry but this policy doesn't cover YOUR type of failure. :mad:

Here's the rest of the story:
http://dieselplace.com/forum/showthread.php?t=172724

Injector failure is injector failure. Talk about a decieving policy. How many people really understand this letter only covers some failures and not all. That's BS. You think you have additional coverage for known problems, and GM :sheephump .
I never got a warning posting here yet, but probably will take a hit for this one.
ANYONE asks me about buying a LB7, I'll tell them don't. GM won't stand up for the customer and fix the problems they have. GM will not get any good recommendations from me.
I hope someone from GM who gives a rats A$$ reads this and passes it up the chain.
My wifes been talking about buying a car. You can guess what brand I won't be buying.

You need to have at least one of the "CONDITION"s listed.

From what I've been told, you must have this one, "as a result of high fuel return
rates due to fuel injector body cracks, ball seat erosion, or high pressure seal extrusion", or the rest don't matter.

They did with the 2001-2003 models - definitely worth a run. Glad to hear they finally came through with the extended warranty for the 04s, way to go GM!

Stock vs. Moded

It doesnt say anything about if the truck has any sort of modifications. Can I assume everything needs to be at stock when taking to GM???

Thanks

If you paid previously, reimbursement directions are in the TSB. The specifically say, don't go to the dealer.

It is all dependant on the dealer, there have been folks get new ones for out of range balance rates, so it is up to the ignorance of the dealers.

No you can not get new injectors just because, try going in under warranty without a problem, and ask for say a new steering wheel, they will probably tell you NO. you have to have a problem, and as for the injectors, they must fall within the guidlines of the SPECIAL POLICY, THIS is NOT, I REPEAT NOT a warranty letter, just a special policy.

I know I will probably be labled as a GM Biased, but I am not that, I am just stateing the obvious as I read it.

Hopefully I will never have to use it. Mine is of the later LB7's, but I know that doesn't mean much....
