Just saw this, and thought I'd ask if your seeing this on your '08.
The voltage reads 14+ when you first start it, but then after you drive a while it drops down to about 13+ or so from what I can tell (it's to the left of the center of the 14V hash mark).
Don't seem to notice any electrical issues at all, and took it on a 200 mile drive Saturday and it would go up to 14, then back down again after driving.
I don't recall if it's been doing this all along, or if I just noticed it the other day.
Curious to see if this is normal or somethings up. Here are some pics. The first is after it's first started, and the second is while driving.
