I had driven two other 3's last week ...no grind sound. I have not returned to the dealer yet (I will when I get my 3 back), but WILL tell the Serv. Mgr. that I want to test drive a new H3 so that I can hear the grind he is talking about. My grind didn't begin until 9 months. Trade in my 3 for a 2? Not in the cards right now ... but is hopefully in long range plans.
