OK, this is a bit strange. The passenger side mirror on my 2008 LX 570 moves slightly from side to side as I motor down the freeway. I am speaking of the actual mirror, not the housing. It does not seem to be loose or to be moving due to the wind. It acts like it is getting small adjustment signals from the side mirror controller. Of course, this is intermittent so my service rep has not observed it. Not a big deal and I have ignored it until today when it annoyed and spooked me, at the same time. I am wondering if any other 570 owners have observed this and hopefully, if they know of the cure. Thanks for any assistance.
