Sync will not connect to phone or Sirius

[Dude]

I don't know who's bright, Gen Z idea it was to have, possibly, the most important daily driving system- that we pay for- completely shut down pending latest updates. It should work with reminders, not shut down, till the owner gets around to updating it. This has already happened to me twice. Both times it had to go to the dealer. Again if I wasn't going to take a bath on this POS, I'd already be back in a Jeep or a Honda.

A complete shut down, in the way you reported, is quite rare with just a few owners reporting that but one of these two fixed the issue:

1. Install SYNC 3, Software Version: 3.4 Build 23188 PRODUCT (or later version if available) and if Customer Satisfaction Program 24B47 (Certain 2018 - 2024 Model Year Various Vehicles: Update SYNC Software) applies to your vehicle then you need to contact a dealership because 24B47 is not an over the air update that you can do yourself. 24B47 can be done by a dealerships mobile service if that service is available in your area.

2. If #1 does not fix the issue, the dealership needs to diagnose the APIM and replace if defective.

I’m confident #1 or #2 will “permanently” fix the issue you are having.
