I’ve got one of these, doesn’t look so great at -5°C either.

Gently de-ice it with a hair dryer or with a hot water bottle.

Happily we didn't even need to try when we had -10 yesterday! When we did have the problem the alarm ping went off after a minute or two but a visual warning remained - the door still wouldn't latch.

Let it be and heat and dry the lock parts with a hairdryer (or park it in an under ground carport for a bit), when you can. Then apply a some silicone spray/grease in to the lock (do not spray on the paint) and on the charge door rubber. Should fix it for a bit.

My charge door froze open today (just shut it after a 1/2 hour in the underground parking), have to dry it really well later today and gently put some silicone in the lock and door rubber.

We were -8°C last night. Even with a charger cover and silicon spayed in it would not shut after charging. So drove off with it open. When was at destination about 20 minutes drive later it then would close. So it’s not a ,
“can’t use” issue but it is a bit of a design issue if you live somewhere cold.

Heated charge port door needs to go on the list for the facelift.

After a closer look, I don't think silicone spray is enough for the lock of the charging door, because the thinner silicone does not prevent water or snow from accumulating inside the locking mechanism. The way the locking mechanism is designed, snow that is on the outside will be pressed into the mechanism when you close the door. Or water can get into the mechanism and freeze, blocking the mechanism.

I think the solution for the locking mechanism is to lubricate it with some form of water/salt resistant grease. So far I have considered acid-free vaseline, a PTFT gun grease (you use what you have) and not least the favorite white lithium/PTFP grease for bicycles (if I can find the tube again). I also see that the dealer has lubricated the lock with grease which has now partially worn away.

Considering all the snow that collects in the charging port/locking mechanism of the charging port door, I think the time has come to buy a rain/snow cover with a magnetic attachment from Ali Express.

Or from Amazon if you want it before winter's over ?

I use CRC Multilube on the rubber and lock. No issues. -17C here.
