Hello, it sounds like there is a draw on the battery with the key off. This can happen if modules don't power down after the engine is off, a relay stuck on can cause this. You can check which circuit has the draw on it by locking the vehicle and allowing the vehicle systems to power down. You'll have to latch the door latch so you can access the interior fuse panels without causing any modules to power up, which will happen if the door is opened, and the latch detected. I dent believe there is a latch switch for the hood on this vehicle. You will need access to both fuse panels in the engine compartment and on the driver side dash. Give the vehicle a good hour after it's been locked up, but door open. This way all the modules will time out and are supposed to power down. Make sure there are no lights on or any accessories on.
After the hour, you can use a basic multimeter set on DC Volts. On the lowest setting. And start checking across each fuse on the little metal tabs on the fuses, none of them should read any low voltage such as 0.3v or lower. If any fuse is reading a low voltage reading, there is current flow happening through that fuse. Once you find the fuse that has a draw on it, we can look up what circuits that fuse powers, and we can have you start to unplug components until the draw is gone. You can also use a thermal sensor to visually see what components might be hot in the vehicle.
But the multimeter technique works well. If you have any questions on the testing just post them here. Or you can have your mechanic do the test, If the battery goes dead after just such a short time, there is a large draw happening on the battery.

This video explains this testing very well.
