I have a 2015 Cruze LTZ. I have had it for approximately 9 mos. the other day it started making this loud annoying high pitched whistling noise on the interstate. Never heard it before. It sounds like it is coming from the front of the car, maybe around the dash. Air is getting in somewhere and making this awful noise. I am inclined to trade the car if it can't be fixed. Anyone else have this problem? I have read of some older models having a windshield seal problem, could that be it?
