Condensation in rear light lenses of a 718 Cayman

Just wondering is the light issue truly they all do that? and also is my reliability experience normal?

Porsche ownership can be character building, see threads on condensers, grills, PDK issues, rusty nut and bolts, headlight cracking, Porsche tax etc. etc., but we tell ourselves that other marques have their own issues and Porsche build such flippin good cars. (No pun intended!)
Get back in the driving seat - it’s fantastic isn’t it. Enjoy!
I follow Neel Jani on instagram and he posted a story of his 992 911 GT3 and it also had the same issue (image attached). It's hard to tell in the image but the whole lower part of the light is filled with condensation.

That sounds logical. If there is no record of damage to the lights caused by this then maybe not a big issue.robertbaird said:Seen only in my rear lights. Seems heat from the engine warms this area in particular and then if the outside air is cooler condensation appears. More a winter problem from what I can see.

So my guess would be that to drive the vehicle on the public highway in this condition may well be illegal!!!
Only a guess though!
Apparently the do all do that. I surrender[

Aside from 'they all do that' being the last thing that a customer ever wants to hear, surely that is an admission that the problem needs to be rectified at source?

Mcmikey62 said:The irony of ‘they all do that’ and it’s connotations with awful cars from the 70’s and 80’s was what got them to make the change. I feel that exposing them to the cost of repairing is the only way to get Porsche to understand it is actually a real issue.
But it's not a fault or an issue - the lights are ventilated (I assume for heat management reasons) therefore the condensation is just a natural combination of slight water ingress and heat from either the units themselves or direct sunlight. If they subsequently clear then all is good, if they don't clear then there's likely to be a blockage in the ventilation system and they should be checked/cleaned/replaced as necessary.
It's not the same situation as the misting up in older, sealed units from years back.

I don't agree, other companies have moved to LED rear lights but don't appear to suffer from the same issue, as I say a walk around Tesco car park confirms that. If there is moisture its only a matter of time before some opportunistic bryophyte takes up residence in there. Then, given the units are sealed in reality, it will be impossible to clean meaning that anyone over 3 years in will be forced to pay for the replacement lights. Aside from that its unsightly, and as my original pictures show, is quite extensive.
