This just started occurring today. Driving along with AC blasting and XM radio on and for a very short time they both go off. The AC stops blowing and music stops playing. For maybe a half second. The screen on the idrive stays on though. Weird. My battery cables seem to be tight. Anyone ever experience this? Thanks.
Come to think of it, mine may have gone at 79,xxx-ish, as well.
As for replacement...I had my Indy do it while I was gone for a month. I had them replace all my rubber hoses and flush ALL (transmission/diff) my fluids -- while you're in there...
I can't remember the price. For just the OEM alternator...$700ish. A Valeo alternator is the OEM manufacturer, and can be found for less.
I just had the same issue happen to me today. Same exact symptoms, AC stops blowing, music stops playing and HUD goes out, all three only stop for a second or two and then come right back. No other issues. 55k on my beast.

We're in this together buddy! :smile I probably won't get my car in til next week to see what's what. It's hotter than Satan's ball here in Louisville. I wonder if that could be a factor.
Just dropped mine at my Indy and they said the battery voltage was reading 17.7. The battery was replaced in January and was coded so we'll see what they find.
Wow! Yeah, like fifty said, sounds like a regulator gone wild. Thanks for the update! Are you going to replace the alternator too just to be safe or just do the regulator?
Your voltage regulator is likely on it's way out. It's an intermittent problem so you may not see it unless you are actively monitoring the voltage at that particular moment. I had the same issue with random electrical gremlins like the iDrive/AC cutting out for a second. Then other electrical systems started to fail like DSC/DBS/Start Assist and your dash starts to light up like an Xmas tree.
I replaced both my alternator and voltage regulator.
Alternator and IBS replaced and all seems to be well in the world again! 14.6 volts at the battery.
