Over the last few months when using the hands free phone option my Infotainment display reboots. When it happens I don't loose my call but about half the time when it come back on radio, volume, music is controlled through the phone. Has anyone else experienced this? I have talked to GM about this, after a month and half finally made connection with CS rep. Their advise is go through the dealership because they (GM) has never had a reported case of this happening. When I get answer I will update post.
