It is my understanding that the system is using all solid state technology.... No more "Hard Drives". Your concern about the auto not returning when the vehicle is restarted is more likely an update to the HVAC control module or the module itself has an issue with communications. To my knowledge this is still a separate module that the UConnect system talks to.
Now saying all of that since none of us here know for sure why the A/C does not turn back on I would suggest you ask your dealer to look at the problem not just to replace a certain part. The best tool this forum can be used for is if your dealer says "working as designed" then you can say no it isn't get me a few Jeeps off your lot and let's test that theory because many of us have verified that it should come back.
I can say working with dealers of all brands that coming in the door and asking for a specific part USUALLY doesn't get you off on the right foot. The requirement at Chrysler is that a customer complaint be duplicated or the concern is a known concern and they can go through their diag chart and verify the failure.
Gathering information in advance on the problem is a great idea but just don't walk in and say you know what the problem is... I know long winded response, but I train people on a regular basis and if it were your job and someone came in telling you how to do it, not knowing anything about you there is a 30% chance you will treat that customer with less respect. I know that isn't correct and service should always have good customer service but IMHO walking in and asking to have anything replaced is a big argument starter in Service.....
If it were me I would say "my A/C is in auto when I turn off my truck and when I turn it back on it is not in auto any more. I checked with some friends with the same vehicle and theirs comes back on"
