Hi BillC15, Sorry to hear about your problem, here's a comment in a review I lifted off this link.

Gibson ES-175: Harmony Central User Reviews

Action, Fit, & Finish : 8
This is always a touchy subject and just about everybody's experience seems to be different, but from my perspective having owned one of these before, I can honestly say my guitar was adequately set-up, constructed well and didn't contain any flaws, The frets and fingerboard inlay were particularly nicely done. One problem with all ES175's is noise from the wiring. Apparently, Gibson likes to give us lots of wire which occasionally relaxes against the underside of the top and vibrates. Any competent tech can fix this problem when you have the guitar in for any work. All in all, the quality of the laminate, finish and detail work on mine is good to excellent accross the board.

This in my opinion may be the problem your guitar's having, so your Concern isn't misplaced, I haven't read all the reviews but a couple did mention buzzes, the reviewer has over 30 years playing experience and knows this guitar well as it isn't the first one he's had and he identified it as a problem and knew it was fixable, this may be what's giving you that buzz so I assume they should be able to sort it out, don't know how much this helps but it does back up what you're saying.
