Steven,
It is standard policy with most PCB shops that they are responsible only for replacement of the fabs, but a good working relationship would dictate otherwise. You vendor should be contacted immediately, as this may be an indicator that they are having a process problem. They should want this feedback, and, whether it is policy or not, they should work with you on recovery of costs incurred. Furthermore, they should foot the bill for the analysis.  Most shops have capability to do it in house.
Listen to that little voice.........don't wait for it to get worse. Your vendor needs your feedback. It's useless from a vendor's point of view to hear that the defect has been seen before, but there is no example available for analysis.

Hi All Ya'll...

I know what I'm about to ask, may seem petty, but I'll ask anyway...

Those of you that read my posts earlier about the delamination/blister deal,
well this is related to that.

Is the persuit to finding out what happened with *these two" boards worth the
time, lab services, etc...worth it?

Like I said earlier, it's only two assemblies...$1,500 dollars at the most, a
decent amount of money to me (I could do a lot with $1,500 dollars), but a
barely a drop in the bucket in the overall scheme of things...

The reason that I'm asking this question, is because I was enlightened by one
of the buyers that even if we do determine that there was a problem with
these *TWO* fabs, the vendor probably will give us two new replacement fabs,
but we can write the components off, as well as our labor...is that pretty
standard?

Like I also said, this is the first time this has happened, with everything
that was shipped to us since November last year...everything has been pretty
good. Reflecting here at home, with a brew in my hand, me thinks I might be
making much ado about nothing...I'll keep this in the ol' memory banks, and
if it gets worse, then I have a history to base my "whinings" on...

So, learned ones, should I go the lab route and analyze everything to "inth"
degree? Or just realize that it maybe was a fluke, and keep an eye out for
the same deal in the future? If it does get worse, then would be the time for
thumb-screws...but part of me says; "Steve, why wait for it to get worse?"

As always, all ya'll, are the best...
