The next time it sticks, use your hand to push the glass into place. Sometimes when washing or drying the mirror you might push the mirror down and it has to be reset. Worth a try.Well, mine still tilt down but my driver side mirror has stopped going back to its regular location when I shift out of reverse about half the time. It ends up somewhere in the middle. I have to put the car in park and hit memory 1 for it to return to the proper setting.
Just the lasted item on my long list of things, big and small, that don't work properly on this car. This problem just started for me this week.
I would tell Infiniti Client Relations about it....if they would return calls.
I believe you need to select the mirror that you want to tilt. If the switch is in the middle neither will tilt.
