Not happy. Car 4500 kms, fsport turbo. Developed a clunking sound when travelling at low speed over rough grounds. Or, accelerating over uneven ground. Clunk is loud enough to hear over radio. On drivers side of car but difficult to pinpoint as to whether it's coming from front or back. Suspect it is a vibration travelling along the vehicles chassis rails, hence difficult to pinpoint.
Believe source maybe a suspension component. Would expect this from a bimmer or Merc, not a Lexus.
Clublexus US has a number of members reporting the same problem. Fixes have included replacement of dampers but does not seem to get rid of problem. May wait for a TSB to be issued.
