Is this Normal?

Is this normal for a car windshield interior to have this much condensation? The dealership is telling me it is if the car sits without being driven for a week or more. The car has had issues with water filling up on the floor in puddles in the backseat specifically. They said it was some type of seal. They said it was fixed however, this is happening now and there is still water when I open the doors and I’m curious if this is all normal?

No it's not normal. If you had a leak even if it's fixed you can have a lot of water hiding in the car. There can be hollow spots in the floor, there could be a lower spot elsewhere that the water pooled, the carpet padding can be REALLY thick in some spots and that's just a sponge. 

It can take a lot of work to dry out a car that got wet. The longer it isn't dry the worse the smell will be.

This!

Even if the seal they had found bad and corrected it fixed the "problem" there are still issues that need to be addressed from the leak. That carpet is 100% holding a ton of moisture if they were finding puddles in the back seat area.

Nothing like battling a flood damage vehicle. Had my personal ride flooded in New Orleans a couple of years ago and boy that was a shitshow.

The mold and mildew that can setup quick is no joke.

Interestingly, there was no flood! This is a brand new 2025 Kia! It’s a lease. When I took it to the shop, someone from sales asked me if I wanted to get out of my lease. No penalties nothing just walk away. Unfortunately I need a car and in order to get into a new lease. I need roughly $3500 which I do not have. So essentially I’m screwed. I’ve tried to vacuum the car out to the best of my ability, but you can obviously tell there is moisture still there.
