On a couple occassions when we have returned to our parked MDX the windows and sunroof are open all the way. I'm not sure if this happens as the vehicle is unlocked/locked with the fob, or there is something else going on internally in the vehicle.

Anyone heard of this issue?

 

There is an auto open window feature from the key fob I believe. Try not to hold the lock or unlock buttons for a long time...the windows will open. Double check owner manual.

 

on the TSX, if you press the unlock button twice, and hold it on the 3rd time, the windows and sunroof begin to open, and if you hold for long enough, they open fully. i can check thursday if it is the same for my moms 2011 MDX tech, but it most likely is
