Is it fogging up when you use the heat or a/c? Is it fogging up after sitting outside on a particularly dewey night?
An easy fix and one to try first is turning the temperature gauge over toward heat, and setting the directional controls to defrost. Up the power on the blower for a moment. The warmer air will usually clear up a foggy windshield in seconds on a chilly or even not-so-chilly morning. The condensation on the glass needs a change of temp in order to evaporate. Sometimes you can get the same effect by using outside air to circulate through your car's blower system. Most have a way of circulating either inside-car air, or outside-car air.
If the glass fogs when you're driving down the road and have the heat on, or the a/c - do you smell something sweet or see white smoke coming out of your air vents? If so, you could have a faulty heater core. I wouldn't imagine this is the problem on such a new vehicle, but it could still malfunction.
Of course, if you're trying to wipe this fog clean and it won't go away, maybe you've got someone smoking in the car and leaving a film on the glass. It would take a lot of smoking to make the windshield look foggy though.
