I bought a new 06 Azera limited with the Ultimate option package. Several times over the years the battery has mysteriously gone dead. (the first when I left it for two weeks on a trip about 2010). I have either just recharged or replaced the battery and gone on with life. Now the car is a second car, and as such sits for a week or more between uses. This month (Jan. 2016), after sitting for perhaps two weeks, the battery was completely dead (2.6 volts). I replaced the battery as it was four years old. After installation I checked the "shut down" current draw and found the car draws right at 250 milliamps when it is all shut down and all possible external devices are unplugged. I checked with and without the hood switch depressed, but it always draws this one quarter amp current. Working the numbers, this means it will deplete the battery of about six amp-hours per day and probably make the car not able to crank in a little more than a week. 250 milliamps is clearly excessive. I talked to my local Hyundai dealer and they are typically useless; they wanted to have the car for "several days" so they can do a circuit-by-circuit examination. When I suggested that sounded expensive, she responded "it can be very expensive". Great! It seems there must be some database of things to check when this occurs, but the rep wasn't going to admit to any such thing.
