After good friend took his car in to the dealership today with the same problem, turns out it is the key fob. Not a problem with the key fob itself, but button on the fob being pushed, most likely while in his pocket by another key on his key ring or perhaps change. Try keeping the fob separate from other objects. Good luck.

Here are some of the more 'common' explanations for unexpected window opening / doors unlocking that we have come across:

1. Key fob button gets accidentally pressed while in pockets.

2. Weak car battery

3. Corrupted software in Body Control Module.

It's a "Safety Feature" designed to stop you getting locked out with a flat battery.  My R53 would occasionally do it, usually when raining...

My guess is you're pocket opening your windows.

 

I know in the R models, if you keep the unlock button pressed on the key fob, it will open all windows and sunroof.

You can do the same to close them by pressing the lock button.

Give it a try and let us know if it works.

Burn to the ground?.. never. Yes, its a BMW aberration, but I do like it....

RE the Blue Tarp:  I think that would draw a little too much attention in the airport parking


I will probably either "take my chances".. its only 5 days. or  pull the sun roof fuse and maybe a window fuse or 2. 
I can at least do the sunroof fuse before I leave for the airport!.

My theory about weak battery is just a guess. It usually happens after sitting idle for a while (but again only has happened 3 times in 2+ years)
But when it happens, my car will turn on, and I can easily, the normal way, shut every window and sunroof again... Andrew

buy can of gasoline and match. aka jewish lighting.  will sort out that BMW MINI  .burn it down to the GROUND.

I had the same problem just last week. Couldn't figure out how to get the windows back up either...





Seriously though - mostly classic Mini folks here. Someone will likely reply, but may not be until Tuesday when they are back at work.

Buy one of those big blue tarps that they sell cheap at Harbour Freight!

I have owned my 2012 rs60 - Countryman all4 for 2 years. 3 times so far, I have come back to my car in the driveway, and it has all windows, open, sunroof fully open, and doors unlocked.
My theory is that when the battery gets low, it does this behaviour. (one time it was overnight, and it had rained, and I had 1/2 inch of water in all my floor mats)
MY worry is that it may happen when I leave my car at the outdoor Airport parking (coming up next week for 5 days)
Can anyone suggest 1 fuse or 2 I could remove to prevent this event from happening, AND still allow me to get back into the car with my key fob ( or the small key IN the key fob!)
I'm not worried about solving the whole problem!.. No idea what REALLY causes it!.. but it is frustrating!
