I'm sure your dealer's service dept. is doing all that they can. After all, it's in their best interest to keep you as a returning, satisfied customer. The guys (and gals) at my dealer's service dept. are also good people. The service mgrs appeared almost as frustrated as I was over my H3 issues. But what the GM/Hummer Corp Customer Service person had told me was true ... another dealer's service dept MAY have come across a similar problem to mine and know what to do. I think that my H3 may have been the first one in with the problem and they (first dealer) didn't know what to think of it after trying different fixes. The 2nd dealer obviously had another H3 with a similar problem like mine, so it was a quick fix for them. If your dealer can't locate your problem, then going to another for THIS concern may be your answer. Good luck and keep us posted.
