It's been raining here in socal over the last few days and my Lightning has just sat on my driveway during this time. Yesterday I got in the truck and all of the windows were fogged up and it was very humid inside. The front windshield was so fogged up, water was dripping down the inside of the windshield. I ran the window defroster and it cleared up for the most part. I did receive a warning that the front camera lens needed cleaning. I checked the front camera on the windshield and it has moisture inside it. Anyone else experience this?

I haven't had that problem yet through our mild wet winter in Southern New England, the plastic shroud from the inside is removable, taking it off might help get more defroster air flow across the area with moisture build up, set the HVAC to full defrost until it's cleared up.

==========
Edit, I think what I was thinking of is not the same area as the trouble spot you're having, but still try DEFROST and AC on at warm temperatures to help with dehumidification.

Do you have the moonroof? Check your drip rails and make sure they are draining. If they are pooling water the interior will be very humid.

How do you do that? What's a drip rail?

Check under your floor mats for moisture. If the carpet is wet you may have a leaking wind shield.

It's the sides of the moonroof frame. The moonroof is designed to leak. On the back and front of each side is a drain tube. Reach your hand up by the window and make sure there isn't any water in the window frame, aka drip rail.

Start watching this video at about 3 minutes. He will explain how it drains.

I have a PRO (no moonroof) and have had this exact same thing happen. Same error displayed (something about safety features not available, camera obstructed). I don’t recall the exact weather conditions at the time but I’ve never had a vehicle have that much moisture on the inside of a window in a closed car.

It's been raining a lot here and zero water or excess moisture in my cab. Can you check with a flashlight (and by touching) all of the floor areas, under the dash, behind the rear seats, etc. and see if anything is wet? Also check the headliner and A pillar. You shouldn't find any water anywhere.

I have a similar issue with water getting in the cab. No windshield fogging, but my floor on the driver side is drenched. I did find the plug near the front and pulled that to help it drain. This NorCal rain is doing a number on whatever is failing.

I discovered my driver-side floor was drenched today after a car wash yesterday. I don't have a moonroof. Water is getting in somewhere. I do see what appears to be a missing grommet under the driver-side floor. I can reach from under the truck and touch the carpet padding. But the volume of water seems unlikely that this was the cause. I still need to investigate.

I use rubber mats, so it may have been an issue for me for a while. In our last significant rain, I did notice water on the top side of my rubber mats. I wasn't sure if it was just rain water from my shoes but now I'm suspect.
