alright, so i have looked this up. No my FOB is not in my pocket. Yes my gf pressed the unlock button for too long. But now everytime i take the key out of ignition they roll down. My key never worked in the door key hole from day one. Dealership f^^^^^d me over on that. (wasnt nissan) It just started today so I dont think its the tumbler problem. But if it was, how do i check it out?

Probably the BCM(body control module). I had the same thing happen with my 04 and 05. The BCM controls nearly everything electrical. I have had the windows roll down on their own when driving, when sitting in the driveway(with or without the key in the ignition). Also, a bad BCM caused me not to be able to unlock the doors, make the horn go off when I put the key in the ignition, make the lights turn on/off by themselves or not work at all.
In the 3 years I owned a Titan, I went through at least 5 BCM's. They apparently don't like rough roads, the dealer always kept a lot of BCM's in stock.

whats the price on one of those? That seems like a defect to me. If its eletrical and water can get in that seems to be poorly manufactured.

Also my computer is telling me after driving 15 kms I went from 156 kms until empty to 89 kms to empty

I don't know what the price is. Mine were changed out on warranty, usually only takes the dealer an hour or so.
Once an electrical gremlin shows its head, others will eventually follow,only solution is to change out the BCM.
Water isn't is the issue, poorly sourced parts are.
I think that if you do a search, you will find many references to failed BCM's.
