Check fuse #18 (20amp, yellow) in the Power Distribution Center box under the hood. This fuse has a plastic pull-tab on it. It's used to control Ignition-Off Draw = IOD. The fuse is pushed in when you take delivery of the vehicle. The owners' manual explains that it's used to keep the battery from draining during extended storage. If it's blown, you will need to determine what caused it to blow. This 20a fuse won't blow unless you've added a load to the circuit or there is a component failure. It doesn't take much to blow the fuse, the addition of a stereo or alarm, or even the power window modification, if you wired it into that circuit. If you haven't added an additional load, and the vehicle self-tests check out OK, dealer service will need to diagnose the problem.
