Recently purchased (1Mo) Tahoe appears to have a rain water ingress somewhere around the top of the windshield or maybe through the trim strips on each side of the roof. Went through three separate heavy rainstorms yesterday and at highway speeds heard a noise overhead before the sunroof that sounded like water being blown around inside the paneling. No visible sign of water and after several miles, it appeared to go away or get blown out by the high speed wind each time after the rain had stopped and road dried. Had what I though was a similar problem with my 2011 Tahoe but could never identify the problem or verify it was water ingress. Anyone have a similar problem with this model?
