I have a 2022 AT4 2500 and it has the same issues. It won’t connect when I’m in the truck, but if I leave the truck running and get out while I’m on the phone, then it connects to the truck and I’m missing the conversation, or they think I’ve hung up so they do the same. If I’m on the phone, it is continuously switching from handset to CarPlay, it makes it impossible to talk on the phone. If I turn everything off, it all comes back on and starts switching between the two again. It’s frustrating enough to make me buy a Ford, almost. I agree with the person who said the truck is too expensive for this crap not to work. I’ve been to the dealer and they’ve checked it, I’ve been on the phone with OnStar for hours trying to figure it out. Also, when I get in the truck, my phone will not automatically connect to the Wi-Fi. I have to open it, select my truck and then connect it. My phone connects to every other network it has ever been logged into automatically, except my truck. It’s aggravating to no end.
