I went on the Department of Transportation's NHTSA web site and filed a complaint regarding the mirror vibrations. The more of us who go on there and file a complaint the more likely they will open up an investigation that could maybe lead to a recall. I did this because I don't know of any other way to pressure Ducati to fix this problem. I contacted Ducati North America which only led to being told to contact my dealer which led to the dealer not being able to fix it (big surprise). I recommend that anyone living in the USA file a complaint; which is about the only way of maybe being able to get this problem fixed by the manufacturer.
