MY22 M3: Moisture In Rear Lamp(s)

[Darkmann]

Mine is a 2022, purchased in the summer. Recently, moisture has been accumulation in the passenger side body tail lamp. It stays damp for a couple of days, sometimes more, before eventually evaporating. The front marker lamps also get moisture but those evaporate in a couple of hours - not a real concern. I took the car in for repair, but it's become worse - now the driver's side does it along with the trunk mounted rear lamps. Really don't feel like doing a day trip back to shop. Does anyone experience this and what would be a solution? Thanks.

Initial Problem - Before Shop "Fix"

These Next Two Pics are After I Returned from Shop - Note that initial issue seems to have been resolved.

There have been a lot (lot) of threads on this topic over the last few years here at TMC. I am not that invested in the topic so I dont have an answer, but here is one of the many threads that showed up when I searched for "moisture in tail lights" as I knew it had come up several times before.

This one is 12 pages long so perhaps there is something in there that might help you. Personally I would take it back to tesla, thats the only answer that would work for me, but perhaps there is something else in the thread:

Moisture condensation in taillights, fog lights, etc

It's been a joy driving in my car but one terrible issue is starting to really bug me. Check out the condensation in my back tail light. I have been driving around like this for at least a month now. =( We had a small bout of rain in LA, and after things cleared up, well, my tail light did not...

I had this happen on my 2018, and a ranger came and swapped the unit. In my case it was only on the passenger side.

After it was removed you can see the amount of water that accumulated.

I like the idea of a ranger coming to fix this. My nearest dealer is too far away. I had to take a day off during my last visit.

Some moisture is normal, it’s only a problem when it never disappeares our ranger told us.

Yeah this should just be a mobile tech fix as they should just swap it out.

Does this water issue affect most Model Ys or is it just a few? Our 22 Model Y Long Range has it too.
