A little condensation is normal in this weather according to Tesla service advisor.

In which case it’s common in all brands.
It’s not in my 76 years of experience however.

Teslas do seem to be especially bad for it but I've seen it quite a bit over the years on all sorts of cars. Normally clears up by mid morning though, anything longer and it's poor design.

Got this on our Ioniq last winter and when queried the service centre they said thats normal as its not a completely sealed unit. Haven't actually noticed anything this year though

Same o x2 in MIC
tesla service says unless water pools at bottom of assembly, it won’t be covered under warranty.
It’s a known issue due to ultrasonic sealing method, allegedly.

Car is garaged at night.

Ultrasonic sealant method is obviously the cheaper way.

The first suggested "watch this next" seems to have the solution. Can be done DIY, he says with about 10 minutes of your time; I suspect it's a fair bit more.

In the olden days the incandescent brake, turn signal & taillight lamps would have enough heat losses to help evaporate any atmospheric condensation from vented automotive lamp housings.

The video referred to a tape over a possible breather hole. If actually present this is likely to be a Gore-Tex fabric membrane or similar product. I have seen this used on a semi sealed case over a vent aperture, when the case is warmed humidity can exit the device, but actual water droplets on the outer surface are repelled.

https://www.gore.com/products/gore-auto ... lectronics

If the these lamp housings have bad perimeter seals and the moisture is not removed the reflectors and lamp circuitry will eventually corrode.

A method to purge the moisture vapours could be to slowly inject very low pressure dry gas (nitrogen) as used on microwave waveguides, or perhaps scuba air into the tiny vent hole.

The Housing vent hole could be closed with a non permeable tape to allow a water spray test to see if the case has perimeter leaks.

Cheers, Steve

Park it with the winter sun directly on it/them and cool off in a dry garage……which is what happens in normal use for us.
I seek sun in winter and shade in summer where it’s available.

Tesla service Perth have ordered new part. Under warranty. ETA end of August.

Car is at 78,603 km since Elon’s 2021 bday. 280621.
So best get it sorted before general warranty runs out at 80,000 km.
