Mine is a 2024 Tucson, so in I'd think it would behave the same, but it is effectively a different car, so who knows, but so far the secret to winter EV in my car has been:
Seat Heaters On
Steering Heat On
Heat OFF
If windshield fogs:
Fan on low to med
Heat temp set to "LOW" ---> NOT the lowest it can go in numbers (17c on mine) but "LOW" which I think equates to "fan only"
"Autodefrost" OFF (Seems to set the heat temp up above low) (Press and hold defrost button to select/deselect)
Defrost button ON
Sometimes if its even colder, the no heat defroster will increases windshield fog then
AC ON (seems counter intuitive, but it adds a dehumidifying effect. Obviously it had better be a short trip at this point, and make sure you are not in a combo windshield + cabin mode or you'll really freeze)

Windshield still fogs, or worse frosts, and I think you have to bite the bullet and run the engine.

My wife and I picked up our new 2023 Tucson PHEV on March 20, 2023. We had waited 16 months since placing the order. I wrote this Facebook post because I thought my friends would be interested in our experience. I explained some things that are well-known to people who hang out on this forum, but are unfamiliar to many of my friends.

I like the car and I'm basically happy with my choice (there are no perfect cars), but you will notice that I do say that a plug-in hybrid is not the right choice for everyone.

Today [March 20, 2024] marks one year with our Hyundai Tucson plug-in hybrid. We have put just over 38,000 km on it (including an 8,000 km round trip from Calgary to Nashville Tennessee). Plug-ins are still a fairly rare sight on the roads (at least around here), so I thought I would share my observations.

A plug-in hybrid vehicle is a variation of a regular hybrid; it has an internal combustion engine, an electric motor, and a battery for that motor (as well as the regular sort of battery used for starting the gas engine). But the battery holds about 10 times the charge of the battery in a regular hybrid, and can be charged from a regular wall outlet or a level 2 electric car charger. (I installed a level 2 240V charger, which charges 6 times faster than a 120V wall outlet charger.) A fully charged battery is supposed to give about 50 km of electric range; once that is gone, it operates like a regular hybrid, sometimes using the gas engine and sometimes the electric motor. Unlike an electric vehicle, you have a gas engine to fall back on and you don't have to worry about your battery becoming depleted when it is 30 below on the Trans-Canada highway near Piapot Saskatchewan.

It basically works as advertised, but on really cold days, the engine stays on to keep the cabin warm so fuel consumption goes up significantly. And for highway driving, the big battery makes the car about 500 pounds heavier than the regular hybrid and the extra space reduces the size of the gas tank, so it has about 150 km less highway range than the regular hybrid. If you do a lot of highway driving, the regular hybrid would serve you better. Also, the wait times for delivery of plug-ins are insanely long (I waited 16 months, and now I hear it is 2 to 3 years). It has its advantages over a regular hybrid, but it's not worth those long waits.

One thing I will say for it: although it has the smallest gas engine of any car I have ever owned (a 1.6 litre turbo 4 cylinder), when it is in sport mode, it has, by far, the best acceleration of any non-sports car I have ever driven. The gas/electric combo has a lot of oomph. No worries about merging on to an expressway or passing on a non-divided highway.
It is comfortable and very nice on long trips and running around town, which are features that it shares with the other drive train versions of the same model.

2 features I wish the car had are

1. to be able to turn on the ventilation fan with out the engine coming on.
2. a small light that would come on for like 1 - 2 mins so you can see the socket while trying to plug the car in when it is dark out

I am out of the country, but search the PHEV forum for my post on a little stick-on light for the charging socket.

From this forum...

Light For Charging Door

I park my PHEV outside. At night, connecting the charging cable to the car can become a Braille exercise. These little stick-on lights fit inside the charging door. Available at Lowes, Home Despot, Amazon, etc. Some reviewers reported difficulty unscrewing the base to replace the batteries...

You should be able to do this by adjusting the interior temperature setting to the same as the outdoor temperature. Then the car won't need to add heat.
