A few of us here with the 2016 models (maybe even 2015) experienced the problem of the USB stick playing automatically upon vehicle startup even though the last item used was the radio, Bluetooth, or XM. My GM dealer tells me that there has not been any firmware updates for my vehicle. I have the guidance option that comes with the 3.6L. Curious if any of the 2017 owners here have the same problem? I have to remove my USB stick with my music library when I shut the vehicle down if I do not want to hear the same playlist start playing every time I start the vehicle.
