I'm in a road trip with the family and experienced something weird with the A/C unit, after a couple hundred miles running at 75mph I had to do a full stop due to traffic, the unit started to blow warm air, I set it up to Low to see if it can be the issue and continued the same, I had to turn the unit completely off and turn it up again in Auto with Low temp to fix it... it did it 2 times more during the trip... anyone experienced something similar?... I was reading another Kia forum and apparently the old Sedona do the same to other people, one of them mentioned that after 4 month the dealer finally found the issue within the unit controller, I want to check with you if a similar situation happened to you guys. Thanks.
