Both windows automatically roll down when door opened.

Sounds like an electrical connection issue on the motor to me. As in, connection was not "optimal" and causing open/close issue, telling the switch to roll down the windows; impact jogged the connection.
So, I'd pull it apart, disconnect the connector from the motor and clean all the contact points really good.

Wiring/connections can do funny things when the pins aren't properly engaging each other. Like most new vehicles, you can roll up/down the windows with the car off until you open the door. It could be possible that a faulty connection could be impacting that feature, too. There's a lot that COULD be happening, so the best thing to do is start with the simplest solutions and work from there. The simplest solution when dealing with electronics is check your grounds, clean your contact points and make sure everything's connected properly.
Also, the primary reason I suggest checking contact points is that in both cases above, impact to the vehicle has "fixed" the issue...thus pointing to a faulty connection.
I've dealt with electronics my entire career (green, Army secret box electronics--not cars), and 99 times out of 100, when you smack something and it starts working again...it's a faulty connector somewhere--you just need to pinpoint where.

I dunno...I'm unsure of the specific wiring schematics in the door, so not giving an absolute "This is it!" answer; simply offering a suggestion...

I have recently been plagued with this problem as well. Hopefully my story will lead to a real fix to this issue.
Driving to work I rolled my windows up and down way more than usual so I suspect that this had something to do with it. Upon arriving to work I rolled the windows up, removed the key from the ignition, opened my drivers door, and immediately both windows rolled all the way down.
-the windows stay up while I'm driving.
-they stay up while the car is parked with the engine off and the key in OR out of the ignition.
-they stay up while the key is removed from the ignition until I open the door(s)
-they stay up with the key in the ignition, engine on or off and the doors open
-the window motors appear to operate normally with no added sounds or signs of strain.
-if I hold the up position on the window switch for 10 seconds or more I can sometimes get one or the other to stay up but never both
-I tried disconnecting the battery
I called Nissan service and they just told me very confidently that I need to replace both motors; no surprise there!
I will keep updating this thread as I go through the troubleshooting. First thing I am going to do is remove my door panels and reset the motors and then I'll try banging on them with a hammer lol.
FWIW my door handles are shaved.
