I posted some observations earlier. I have looked at the owner's manual but it is kind of like reading an encyclopedia. I am having these issues;

Today when I went to get into my Infiniti the windows were both down about 2/3. Sometimes one or both are all the way down.

The doors are sometimes locked.

Once the gas guage gets to about ½ tank I occasionally get a "beep" and a yellow triangle light will flash on on the cluster near the 45mph mark just outside of the speedometer dial. This happens when I hit a small bum in the road.

The door locking could be me hitting the switch of the key I carry in my pocket. I park the car in a garage under my bedroom.

 

These could both be the result of you carrying the key in your pocket. Pressing and holding the unlock button on the key fob will lower the windows until you release it or they're full down.

I would guess this is the result of a known issue with the fuel tank level float, there is a TSB out there for it.

 

Regarding the light blinking and the "beep", I looked at the list of TSBs and I did a word search here and couldn't find anything.
