I am also new to this forum, for the same reason! Exactly the same reason!! I just purchased a used 2014 Cruze LTZ w/ 32k miles and absolutely LOVE it, but, today we started having issues with the radio and HVAC randomly turning off and on!!! After reading this thread I am going to take it in to the same dealer that replaced the dash in my Silverado under warranty and have them look at the Negative Battery Terminal AND replace the relay just to cover all the bases. Will post update. Thank you everyone for the info :]
