Got the new microphone installed today and I had the 15,000 mile service done (at 14,000 miles) with synthetic oil which I've been using since the first oil & filter change. They did the full deal oil & filter, air filter (if you're changing your own make sure you're ready for an air filter change), tire rotation, etc.
They replaced the microphone and I asked them to not just plug a new one in replacing the previous one but to replace the wiring (per Brian's recommendation). They pulled the headliner and found "bad wiring" and they replaced it as well so I expect that this is the end of the "replace the microphone again" cycle.
BTW, for those of you that are interested, I was told that Ford will do an alignment on your Raptor for free once, IF you're under 12,000 miles. My Raptor's not having any symptoms of alignment issues (uneven tire wear and/or shimmy in the front end) so I didn't have them do an alignment which I would have had to pay for.
