Model 3 production issue: Water gets into tail lights

[alcfeoh]

First rain experience for my Model 3 and I can see humidity inside the left tail light, which is the only one to be impacted. Is it a common occurrence with Model 3?
Note that mine was built during the record production week in July when they exceeded 5,000 Model 3s, so I'm not surprised to find a few imperfections.

Did anyone else have similar issues? I so, any short term fix before I bring my car at the service center?

humidity does get in there but will usually clear out. If it never clears then you have an issue.
I had that happen to one tail light that never cleared.
If you look closely at the light you'll see a little hole in the light (its supposed to be there)

Actually I see a tiny circle but no hole. That might be the issue. Perhaps my M3 is just missing those tiny holes. Could you post of picture of one of yours just to see where they're supposed to be?

A little fogging with a major temperature shift might be fairly normal, but beading condensation is not. You should get it replaced.

Yes I notice it after heavy rain or car wash. It clears after a day or two.

It's been 3-4 days and still there, in the ultra dry Sacramento climate, that's even more surprising, hence my concern.

My Model X tail lights fog after a car wash, but clear in 5-10 minutes. Anything that takes a day or two to clear is too much in my opinion.

Any fogging requires lens replacement. It will eventually permanently show. My Model S had the issue.

Used to happen on my S. Service had a fix.

Has to be a sustained all day rain. I use a pressure washer on my car, that doesn't help. If it's very hot outside tail lights clear in an hour.

Schedule a service appointment you probably have a bad gasket, or tail light wasn't properly installed.

Had the same problem, service center replaced it, took an hour or so

 

[Garrett0606]

Had the same issue twice. Mobile repair did both in about 10 min.

Same issue for my Model 3, which was also manufactured in July 2018. I emailed the service center and received a call back the next day indicating a new taillight was ordered and they will reach out when it is in and ready for install.

No water in your trunk I hope?

Been having the same problem. It's been persistent for a few weeks so I called customer support and they said they'll send someone to my house to fix it this week. This is the only problem I've had with the car so far. I'm satisfied with everything; my previous vehicles have been much more trouble.

You should get that replaced. That’s an issue. I had an issue with my other non Tesla before. Headlight and they also had to replace it.

Also have a M3 manufactured in July 2018 with condesation on the rear left lense cover. Service Center took a picture so they could order new part. Told it would arrive in 6 to 8 weeks.
Still waiting. Still have condensation.

Same with my July ‘18 build. See picture. Still water in light a week after car wash so service relaced it. I went to pick up from service today and found water in lower trunk, so that may or may not be related. It should be noted that I had to touch the lining at the bottom trunk to know it was wet because it was soaked into the material like a wet sponge. Thanks to this forum I knew to check in there. I hope that’s not related to why those bumpers mysteriously fell off of a few m3 some weeks back!! I’m guessing there was more than a trivial amount of water in there below the trunk lining. I still love the car but concerning nonetheless.

I had noticed the same issue after I took delivery. I have scheduled for service next week to get it replaced.
