On my 1 month old S I found that occasionally the driver side mirror seemed to lose the setting. It didn't look like I set it up before and I had to readjust it. Not every time but enough to notice it. I finally figured out today what's going on, and that's on occasion the mirror does not fold out completely. It stops about maybe 1/2 inch before getting to where it should be. And then obviously the mirror position is off. Once I realized that, I seem to be able to push to the right place either by hand or by folding it in/out once with the button. The other mirror is fine every time. Anyone else observer something like this? Should I stop folding the mirrors every time, I have it on auto-fold. Is this worth a visit to Service?
