I took delivery of my 2004 GX on 10/1/2004, and I have had no problems with it at all. None. I take it in for oil changes and tire rotation, and I've had the 15,000 mile service done, but that's it. Some others with 04/05 models have had that "clunk" thing come up, but I have not encountered it in mine. I've owned lots of cars before...from corvettes to Hondas to Cadillacs, and have never had a vehicle as trouble free as my Lexus has been.
