Any condensation in the headlight should be unacceptable because it reduces the light output and changes the beam focus. Those headlights need to be replaced, but fortunately it's a simple part swap. Tesla will change out the entire headlight assembly with a new one.
I had a recurring issue here in Arizona that required the creation of a new service bulletin. My particular issue was the service center's inability to properly resolve moisture and dust intrusion into my rear backup tail lights (the bright white ones). The appliqué was replaced four times, each time the problem shifts from one side to the other. This last time they engaged engineering who offered a different solution that resulted in a service bulletin. If you are unable to have your rear lights properly fixed, ask your SC to contact the Scottsdale SC for how they resolved my issue. Since the last fix I have not had any more issues. They either used a different seal or a different adhesive.
That's a weird response from the SC, moisture inside the headlights is unacceptable and you should speak with them again, I'm yet to see a headlight on any car that's leaking water.
Few weeks ago when I noticed my rear lights with water inside, SC replaced them immediately with no questions asked, you should expect the same.
Upping this old thread in case anybody has new info. I woke up today, after a few days of rain, to a very fogged right headlight. Left one is just fine.
I had a minor fender bender this April that did not damage the light. My first thought today was that the seal is busted and the unit needs to be replaced. But from this thread it sounds like this might be within expected range? I did not see it happen after regular car washes.
Apologies for the upside down pic. For some reason it wants to show up like that when I upload it, no matter what the original pic looks like...
Condensation accumulated in my 2013 non tech package passenger headlight this year. Inspection of my old headlights showed that the seals had been compromised. Ordered replacements on Ebay. Saved a bundle vs. going through Tesla.
Thanks! I am probably in the same situation. Very helpful. Did you replace yourself or did you get help from a body shop? I did some digging and saw that replacing the headlight requires removing the bumper, which gives me some pause.
