: Is condensation on the inside of windshield normal?

Noticing a recurring problem with my 2013 SRX. Perhaps its nothing. I will leave it to you to decide.

When I get to my vehicle in the evening, there is a layer of fog on the window. Seems to happen quite often. I live in the NYC metro area so the weather has been in the 40s by day and then we get an arctic blast in the evening.

Perhaps the fog is normal, as the vehicle has a defogger to deal with these things, but the annoying aspect of it all is that it seems to happen quite frequently, and even after defogging, the window has a dirty film across it. I don't smoke, so I don't know why the window is retaining a smudge effect.

Also noticed the front headlight was fogged up as well.

Again, maybe nothing. Only reason I bring it up is because I never had this problem with my 2010 SRX (or as frequently). I want to be certain there is not a seal issue here. Perhaps someone can tell me what should be considered normal for foggy windows and headlights.

As always, thanks for the help here.

EDIT: The more I read, the more that I see this is a normal occurrence when warm air meets cold. Certainly, that is the kind of temperature we have been having here. Also reading that cleaning the inside of the windshield with good glass cleaner will help (which I will do today). Again, I think I am more concerned with the increased frequency of the window fog, but probably all weather related.

The window fog happens every time you take a vehicle from a warm garage out into the cold winter air here. The condensation is normal, and the only way to avoid it is to keep the vehicle constantly cold (which can't happen if you plan on using it) or moving to a warmer climate.

Welcome to winter! (Also yes the headlights will do similar fogging. Nothing to worry about unless the fog turns into water. The headlights have a vent to atmosphere to attempt to help with this, but it also works backwards when the lights are off)

Captain, I can always rely on you for a comforting response.

It probably makes no difference from your explanation, but actually, the car sits outside all day.

I am guessing it's the sudden change of temperature that we are having day to night.

That would do it. You will see it on days where the humidity level takes a huge swing as well.

Yes thanks Captain for that explanation. The problem I have, is when that moisture on the inside of the windshield freezes. Very annoying.
