moisture

I have a 2010 genises 3.8 trac and have noticed moisture sometimes forms inside the headlight lenses. I've never noticed this on my other cars. They havent been damaged. Anyone experienced this?

Recently purchsed a CPO car and am trying to go over it before the 60k warranty flies by. Noticed moisture in the corners of both headlights tonight. Hasn't rained in a couple of days and it was 50-ish degrees out. Aren't these sealed? Covered under warranty?

I purchased a 2012 Genesis V-6 w/tech package last July. About 3 weeks later I went through a car wash. A few minutes later I lost all sound. Turned car off and back on - no luck. After getting home and letting car sit overnite the sound worked next morning. Dealer could find nothing wrong...
