Suburban2015

I was wondering if you guys have a roof rack with the cross bars installed? I was one of the first to get the 15 Suburban and had that wind buffeting in cabin drone noise...I installed the roof cross bars and I'm not sure if that solved my issue or if it was when the dealer replaced my side roof bar.

I believe I helped my problem when I first got my 2015 LTZ Suburban by installed roof racks. Somehow this helped with the pressure vacuum I was experiencing.

I've just started to notice this in my 15 suburban ltz.

I have a 2015 Suburban LTD and was one of the first to get it in March. The sound is a tunnel effect. I have just accepted the issue... it is a design issue I assume and trying to get answers is useless. Just like the issues with the USB ports not giving enough amps to charge a phone. My note 4 will barely get enough power via direct usb but if I use cig adapter it charges and if I use the 12 volt plug is give 1200 amps.
