Headlamp become foggy after car wash

Hello everyone hope you’re doing well.
Did anyone notice headlamp become foggy after car wash. I took it to the dealership and told me this is normal if no water going through the headlamp.

Not sure about the head lamp but some do have ventilation so fogging is normal. However, I have water inside left tail lamp already. Pretty sure it’s leaking. I’m going to the dealer next week.

Got to love the Mexican built quality 😒

Condensation inside the housing means moisture will enter the wiring harness and rot it out. As well as damaging the reflective surfaces.

So either you bring it in now and have it replaced under warranty.

Condensation in LED headlights is normal, the vents the allow the moisture in are necessary. As for the taillights, there should be no moisture in the housing. They may be LED but nowhere near the power output of the headlights. Get the dealer to check it out and even if he finds nothing wrong get him to note it on the work order just in case something shows up in the future.
