Just to follow up. Took it back to our dealer this morning. My wife was told that there wasn't a problem with the a/c. She pitched a fit and then learned that the unit was cooling on the driver's side, but not on the passenger's side and the rear unit. We learned it may be in for a couple days and they gave us an X3 loaner. I'm a little miffed as I was skeptical of this a/c upon delivery and was told it was because it was brand new.
