Faulty Flap motor might be the issue. Sometimes the actual climate head units go wonky but doubt that on a newer car like yours. Would have a look at the fuses for good measure. If that does not help have a look inside the blower motor box and see if anything is blocking the vent door in there. If nothing above does not pan out a factory service tool would be the another option but that would require a service station or dealer with factory scan tool to see if there is a specific issue with the blend door motors or the climate module itself. Good Luck!
