What system does your truck has for an information system: IE such as APPLE CAR PLAY or something similar.
My wife's 2021 Santa FE has Apple car play (Android WORKS ALSO) whenever there is an issue with the phone not linking up, it tends to be the phone that is causing the issues. Try to open any APPS and the general settings in the phone to see if something is turned off and should be on. Also turn your phone off and on. Delete the phone from your truck's information system and then trying to pair the phone to your truck information system again, to see if that helps.
I don't know on the android phones but with the apple phones you need to swipe down and see if the Bluetooth is turn on. It is not in the general settings but in the swipe down screen on some apple phones. This sometimes will cause an issue in linking up.
Good luck and let us know how the issue turns out.
