I had this with another car and it was the wipers...

What I would do;

make sure it is not raining or going to

tape your windwipers down to the windshield or if you are comfortable enough with the idea, remove the wiper blades from the arms

take it on the road, if the sounds is gone

take it to the dealer and have them re adjust the wipers on the window, either up or down (probably last one is better)

hope this helps you
