Yep !!
I thought I was going crazy
after rain or car wash - I describe it as ping pong balls between windshield and sunroof
last 20 minutes at highway speed
very annoying
my dealer in Rochester NY— had it in twice “ can hear it “
just called today - rep said they have a 2021 Tahoe in shop with same thing -told it is a “ normal “ part of drainage sunroof
should have stuck with my Audi Q7- but wanna buy American
