299,999 + Mile Club

Hi Gang...... Just figured out how to get in here. Last Friday I was all excited when my odometer on my 05 was at 299,998, watched it go to 299,999 and then it locked up. So I came on here and find that this is a real problem. I went to my dealer and of course they are playing dumb at this point. I told them that I had been to the forum and that this appears to be a common problem with those of us who are high mileage folks and that it must be either a firm ware or soft ware problem and would the please check for service bulletins. The are checking. Has anyone else got a dealer who had corrected the issue for them. This is a design problem? Of course the dealer wants $125+ to hook me up to the computer to diagnose the problem. I told them that the should be giving us new cars, or at least not charge us for fixing the problem that is built in to the car. So if anyone has obtained a solution I would love to have it and pass on to my service manager.
