mirror moving

Has anyone else noted problems tilting the driver side mirror out far enough to cover the 'blind spot'? I have checked several and they all seem problematic. My older 2007 Hoe worked fine. It seems not to be the range of motion, but the 'centering' of it.

I just got a 2008 Tahoe LTZ and I am new to this site. I noticed when the unlock button is pressed on the remote the passenger side mirror adjusts out and up. Any clues why this is happening?
