What is your question?
Once in a while when I'm sitting at a red light, the temp gauge goes up a bit and the a/c blows warm. Once I start driving, it goes back to normal.
How long has your 2018 Hyundai Elantra had this problem?
More than a month

Hi - Dave here, contributing to RepairPal and providing expert advice since 2010. Sounds like maybe there could be a cooling fan issue. Just a guess, but it checks the boxes of not cooling the engine radiator coolant as needed when not moving, and also the condenser not getting the refrigerant cooled. Check the cooling fan operation first. https://repairpal.com/auto-repair-near-me Click the link to find some shops near you who can help out!
