Have a 2015 F-250 6.7L Lariat with Sync 2 and iPhone 11. Never had any connectivity or other issues until a week - 10 days ago. iPhone 11 with IOS 13.3 and 3.10 Sync version started randomly disconnecting. Happens multiple and several times depending on how long I am in my truck. Have done all the typical, delete phone from Sync, restart phone, re-pair, etc and still happening. Anyone else having issues? Not sure I it s IOS/Apple or Sync.

 

Don't have a I Phone but I do have Sync 2 and it has random problems every few months. Taked to a dealership and I was told to make a video on my phone so they could see what it was was doing when pull the fuse or disconnect the battery to reboot the system and see if it goes away. Mine always goes back to normal after a reboot. On my 2013 it's fuse #29 but it's easier to just disconnect the battery. Sync 2 is a big piece of you know what. The last time it happened the radio wouldn't shut off when the truck was turned off but it's never same problem

There ain't nothing wrong with your phone I guarantee you pardner it's that junk no good POS Sync. I went round and round with Ford on mine and finally got sick of fighting with them. I'm gonna trash it one of these days if I don't junk the whole truck first.
