I have a 2019 Santa Fe. I am having an issue with condensation and sometimes even frost on the inside of the windshield. I have never had a car do this before. Just bought this car with 16K miles on it. I reside in Southern CA so it never really gets that cold here. I usually put a windshield sun reflector when the car is parked. Thought that might be the issue but the condensation, while a bit less, still forms at the bottom of the windshield inside the car. Any ideas out there on what can be happening? Everything inside the car is nice and dry. No wet mats or rugs.
