Bought a new 2019 Hyundai Santa Fe in April. The wife complained that this morning she had to use the scraper on the inside of the windshield. I told her to crack the window a little or both sides to let the car vent. It may be too air tight.

Recirculate mode on accidentally? I live somewhere colder than you and I've never scraped the inside of a windshield in my life.

+1

the recirc mode is commonly used in summer for max cooling.
Many drivers forget to turn this off in fall/winter and it leads to excessive humidity in the interior and condensation (which turns to ice in colder temps).
Living in Canada, I've personally never had this happen on my cars, but seen it on others.

Happened to me a week ago..... same vehicle / same model / same age. Change your circulation mode.

Have not seen ice on the inside windshield, since i owned an aircooled porsche 914.

I agree ,turn off the recirc, and i run the ac when defrosting to dry the air.

Also clean the inside of the windshield. Dirt gives water molecules more surface area to cling to.

Check the carpets, everywhere, see if they are damp.

Back in the day, I remember using a cigarette lighter to thaw the frost off the inside of the windshield while driving. Air cooled VW. Think no heat. It was better to open the outside air vents to direct outside air to the windshield because the humidity from your breath would condense on the windshield and freeze.

This I agree with as well. The humidity is coming from somewhere. If it continues without finding a source I would have the dealer check it out under warranty.

That used to happen all the time on VW beetles. I remember people scraping both inside and outside - while driving! In that case it was the limited heater.

Sounds like your issue is recycle mode.

My 1976 CJ-5 Jeep had the issue with frost on the inside of the windshield. I think some of it was my breath freezing on the windshield.
