Driver side door mirror would tip down when the car was put in reverse (as it should), but would not tip back up when the car was put in drive. Very annoying to have to adjust driver side mirror every time after I put the car in reverse. I would be fine with a mirror than never tipped down, so tipping back up would never be an issue. Too much complexity in the MDX. It's nice when stuff works, but expensive and annoying when fancy features fail.
