Update to this topic if interested. It seems that Lexus has finally admitted that this problem is endemic and are gearing up to replace the dash boards on 2003-2009 GX470's entirely at their cost. I have checked this fact with my Lexus dealer and they confirmed. They are going to have parts available for the repairs by May 2015. I've heard they ask some pretty tough questions to qualify you, but my dealer said that they would probably replace all that come in. I guess now the question is if they will give refunds for all of those who went the route of paying for the repair themselves.
