Question about condensation on my 2010 mazda 3 s gt tail lights

Hi,
I had my car washed few weeks ago and noticed there was some condensation inside the right rear tail light. I called my dealer and the guy I talked to, told me that it was normal since the tail lights on 2010 mazda 3 are naturally ventilated and they are supposed to do that. Is this true or he was just talking out of his behind? The car only has 20k in it and if there is something wrong with it, does their warranty cover this?

Thanks and sorry if someone else had posted this before... Just need some advises.

Most of recent vehicle's taillight housing is designed that way ( ventilated whatever they want to call) to prevent condensation.

There is gasket between body and tail housing that is compressed to create seal.
If tail housing isn't tighten onto body enough, it may get week gasket compression, allow some water to leak in.

Or if gasket is worn somehow, same result.

Which part of tail housing you see condensation? If you see condensation only along certain lens edge, you may want to suspect housing/unit seal problem(seam crack).

Very slight condensation can occur in extreme climate, sudden temp shift, but if you see visible water sport inside, likely that's leak. Not normal.

I have the same year+model as you and noticed a small fogged area on my tail light this morning. I'm going to blame it on the cold front that just blew through and hope I don't see it in normal conditions...
