Well, it appears to not be a consistent change. I tried to start my truck yesterday after work (about 4.5 hours shut off) and it failed. I tried this morning after about 12 hours and it failed too. I'll try tonight after about 2 hours to see if something shorter works.
I brought my truck in for this to be diagnosed and they reset the radio on the first visit (of course). They then waited for a few days for feedback while I had a loaner truck. I asked for my truck back so I could drive what I'm making payments on and then discovered that when they reset the radio now my Assist and SOS buttons didn't work. I just got a screen prompt that said something like, "Try again later". I went through some pains to get that working again by calling 2 times and waiting 3 days for my account to be "activated" again. A little over a week later FCA STAR asked my dealer to take some pictures of some radio screens while it was in dealer mode. Since that visit over my lunch hour, my truck has lost my phone bluetooth pairing 3 times. This last time I had to restart the truck and my phone and pair the phone again to get it to work.
I don't have my STAR case #, but I can ask. My UConnect case # is 57759906.
