Just logged the first thousand miles on the new LS430. Now that I feel OK about running at higher speeds, I noticed that I hear a low-pitched hum at 75-80 MPH. Almost sounds like an exhaust pipe touching the body, but if I slip the tranny into neutral and let it down to idle, the sound is still there.

Is there anything that may be creating a wind resonance? This is the sort of thing I'm scared to bring to a dealer, because they won't likely find anything -- but the moaning will drive me bat-$h!t.

Anybondy else ever run into anything like this?
