I want to thank everyone for their advice. I will probably give in and buy a OBD reader and set it up with my phone. I have followed the advice of Ioniq Guy and Cars Made Simple when trying to activate the battery preconditioning and the fist hint that it's not working is there has never been the little pop up message telling that me that "Battery conditioning activated for optimal DC charging". I tried selecting DC fast chargers near me, more than 30 miles away, more than 30 miles away with less than 30 miles of range, all in temps below 45F. I susepect as I noted above that the updates were installed out of sequence and without some more informed testing, it wont be clear. Next step will be to get in line at the dealer service department. But, sadly, in my expereince these guys will try to perform an oil change.
