In visiting the GX 460 forum there are quite a few problems with brake rotors. They claim Lexus used to exchange new rotors when an owner experienced problems but now they turn the rotors first and then exchange if there is still a problem. The reason I asked the question was several owners of the GX460 also own LX570s and some of those are experiencing problems. I haven't seen any problems on here so just wondered if I missed them. Thanks!
