^^I'd be load testing the battery to see if it has a shorted cell right after making sure the terminals are tight and the other end of the terminal wires are tight. The only other reasonable possibility would be an alternator voltage regulator problem, but Japanese cars generally don't have alternator issues until they are very high mileage.

OP, did the dealer get this resolved or at least figure out what's wrong with it?
I'm not advocating short drives by any means, but I have an 8-mile commute per day (i.e., 4 miles in each direction) and am very heavy city driving, and I haven't had any battery problems... yet.

Common things are common. Electrical interruption either from loose connection(battery) or a bad battery(cell) as already mentioned. Disconnect check replace/reconnect battery. Should fix ya up.

the window auto up down feature can be reset by going to each window switch and rolling the window half way down then all the way up and hold the button up for 1 second after it finishes going up. You have to do this from each windows individual switch and not from the 4 on the drivers controls.

Bad battery, hands down.
If the terminals are clean and tight, replace the battery with a known-good, fully charged one. Re-initialize all the windows and radio and stuff per the owner's manual.
The only exception is if the car has had aftermarket electronics added. A bad install job and who knows.
