Loss of communication?

Hmm!? Here’s one for everyone. Been working on this problem for a few months. Started sometime last winter. Park sensor temporarily unavailable warning comes up on my dash. Then eventually service shifter warning comes on. If the vehicle is in cruise control the vehicle kicks it off. When the cab is hot from the warm weather when the vehicle is off and you start the vehicle these warnings will come on harder and periodically the transmission will not go into gear. Then you get it going again when you turn the vehicle off then on again. Two Ram dealerships one in Nevada twice and in California twice and countless days attempted to repair the problem but have failed. They have tried replacing the Pam module (park assist module ? ) twice and a star connector once. But that did not rectify the problem! Any ideas out there??!! Would be much appreciated. I don’t think Ram knows where to go from here. This is a 2019 Ram Rebel 47000 miles
