I have a 2012 GT and I am currently having that problem. Initially I took it to my mechanic a year ago and he replaced the starter and the battery. Issue continued literally the next day. Battery dead. I had been jump starting it until another person that replaced my a/c compressor said it was my radio and that Shaker systems eventually cause problems. He took out the 20 radio fuse and I have had no problem starting it until I replaced the entire radio, amp and speakers last week. Now that the fuse is back in…. Battery dead and my air conditioner is blowing hot air! So replacing the radio wasn’t my solution either. There is a parasitic drain somewhere and having to get an electrical mechanic to look at it now. I’m frustrated and trending on broke at this point...
@Bad6969BoyI replaced the old radio with a new original stock Ford radio. The brand new apple car play did not work in that car. Then I replaced the battery and Alternator and it fixed the issue.
