Does anyone else's car fog up like crazy? Is it just the weather?

My headlights are even fogging! It's annoying!

Also unrelated, did your cars come with a frunk cargo net?

Cars came with frunk cargo net.

Both my cars (the ICE and the S) fogged up pretty bad yesterday. Then again, it was foggy out too.

I got the front net, but no license plate frame. Yes though, my windows fog up a LOT.

No aircon.

My DS seems to think I shouldn't be getting a Frunk cargo net. I'll email Tesla.

I'll take some pictures. The fogged headlights don't look great. I thought headlights are sealed. The are fogged from the inside. As does my rear view camera, gets really wet too. Rain-X?

Do you have aircon on when getting this fogging?

If your windows are fogging in your temperate climates, I am not encouraged as to how it will be in winter... Not much worse than windows covered with frozen water vapor on the inside of the car, especially if it occurs despite using the ventilation system / A/C.

Anemic ventilation / defrosting ability would be one of the few things that would make me consider cancelling my reservation...

Say it ain't so!

The chemicals coming from the new materials are placing a coating upon the windows that absorbs moisture and fogs up. Paper towels and a good glass cleaner should help quite a bit. I noticed the fogging at about 600 miles or so and it fogs much less if you keep the inside of the glass clean.

Yes, in about 45 deg weather. If I tap the rear defroster all is well, but with that unlit and "Auto" for all the other Climate Control it fogs up. Also, when it's 40-50 the auto fan speed isn't fast enough to keep me warm.

This! The windshield interior is much clearer where I've been able to wipe it clean. (Bit hard to get to the very front of it.)

um, yeah, headlamps should be sealed... anyone else having this condensation on the inside issue? this is a 'replace headlamp assembly' thing if ever i heard one..

The Roadsters had fogging headlight problems in spades until they came out with improved units. Presumably they've learned from that experience so maybe you've got defective or improperly installed units?

The interior of the Model S fogs easily because it's so well sealed. You need to run the fan and/or A/C.
I don't see it being an issue in the Winter -- it's just that it's really easy to increase the interior humidity; when the exterior temp is 45F, the heat and fan barely runs, so it fogs up. That will likely not be true in <32F conditions (which is so far what I've observed).

It occurs to me that people should check whether they are on recirculate or fresh-air. Humans emit a great deal of water vapor.
Funny, last time I mentioned recirculate most of the replies said it has nothing to do with defogging. Until the Texas folks chimed in. ;)
