I have a 2010 Platinum with 1200 miles on her. We were coming home the other night down a rural un-paved road and heard a rattle under the front end, sounds like something is loose, but cannot figure out what it could possibly be. Our Lexus GX470 made a similar noise when the oil chnage shop didn't tighten the skid plate properly. Taking it into the dealer this week to see what they can find. This should be fun. . . .
