iPhone 13 Pro Max UCONNECT random issues

I purchased my device in Dec 2021. I have a 2014 Town and Country. About Aug/Sep after a phone update, I started having issues with my connection randomly transferring back and forth from the van to the phone, it connecting to UCONNECT however the call only comes to the phone and my phone not connecting to UCONNECT; all just randomly occurs . I’ve had the UCONNECT updated and my

phone is also. Please help!!
