Water condensing in both taillight lenses.

Just discovered water fogging the inside of both taillight lenses, along almost the entire side of the lenses as they sweep toward the front. I hate to have to make GM replace the entire taillight lenses, but will ask for it when I get the recall and Android Auto programming done in a couple of weeks. What I've seen in the past is that eventually a white corrosion deposit develops on the brass bulb sockets. Plus, it looks bad on an almost new car. Anyone else notice this? And have you had them replaced? I would have figured these are pretty well sealed units in this day and age, except for the bulb hole.

I've noticed it too....Not sure if it's common...Especially after a car wash on cold days, it's very noticable. But it seems to go away when it warms up a bit.

The same thing happens on some Gen 1's. I've just had both my tail lamps replaced.

If it's just a misting after a car wash or heavy rain and it goes away within a few hours.... normal
If it's the whole lens, and it stays, even on a sunny day... defective.

See this thread "Taillight water"
Images are Gen 1, but you get the idea of a little moisture vs defect.

Some condensation is normal. But I had my Gen 1s replaced because it would never clear up. Be sure to get it done under the bumper to bumper warranty.
