Unbearable high-pitched screeching wind sound (NOT A WHISPERING NOISE) mainly from driver's side front window, often on passenger's side also. Seems mostly to be a severe problem when crosswind is coming from N to S or S to N. Two hour drive-4 hour drive-6 hour drive constant noise! Dealership won't do anything until a fix comes from Hyundai. Honestly, after six hours of what should have been a pleasant drive, I was ready to knock the window out. Doesn't make the sound all the time. Have noticed when wind if buffed by a tree line or another vehicle noise subsides some. Has to be gasket problem...why can't this be resolved quickly. PLEASE
