2020 blazer redline edition

My blazer just hit 4000 miles and i am having issues with the radio. Started two days ago. It will not come on through any foruM (FM, Sirius XM, iPhone, etc) sometimes it will Blast out for maybe a couple of seconds then gone again. I have an appt with the dealership on Monday. I was very impressed with this car but starting to get disappointed and discouraged reading all the issues this car has had. So many ppl i am reading are having the same issues. 😏 #disappointed esp for the money. Very expensive.
