Dealership states there is not a problem as no problems show up on their diagnostic machine and the temperature coming out is in the normal range; I must often drive with the temp on the lowest available setting and vent on highest available setting to remain cool. I have no doubt that in 2019 when no longer under standard 36 month warranty the problem will be found, on my dime. Possible compressor issue worsening or bad temperature blend door actuator for passenger side on AC evaporator case. No doubt that when the issue is resolved I will commended on the use of my crystal ball (after I settle the bill.)
