Just noticed the other day mine do the same thing. I have the black titanium's and they get really hazy inside in the morning. Is it normal for them to fog up on the inside? My last focus i had for 10+ years had vented headlights never fogged up on the inside. I'll mention it to the dealer I guess the next time I get my oil changed.
