Every headlight from any manufacturer has vents to prevent this from occurring. It is not normal. Gen 1's do not have this problem never once have I had it happen on my Raptor in the rain cold or snow. Def take care of it.

Take it in. It's only 3 bolts to take them off easy swap.
You're probably right about this occurrence being abnormal in headlight housings. We've witnessed enough of a sample size of gen 2 owners having the same issue, which leads me to deduct this is more so a design flaw of the housings rather than a one off lemon or defect.
If my deduction is true, then even if they get replaced under warranty, wouldn't it be just a matter of time before the moisture occurred again?
This reminds me of the gen 1 third brake light housing that was extremely susceptible to moisture penetration. I heard and read that Ford improved the gaskets but they still allowed moisture to get in over time.
Then again, the headlight assembly is far more critical than the LED third brakelight, so perhaps Ford will improve the design completely and replace the original defective ones under warranty.
