Condensation In Tail Light

[BeeBee]

We’ve only had our MY since March and due to COVID it’s been garaged much of the time. It’s only been driven in the rain 2 or 3 times. There must be a leaky seam somewhere. I hope it’s covered by the warranty.

As has been discussed, tail lights are not sealed, so moisture may enter. Fortunately, tail lights are not sealed, so moisture may escape. This is in the owners manual of a wide variety of cars.

Any car I’ve had where the moisture didn’t almost immediately dissipate had an Issue with the taillight. Heck, the best evidence for that is that it was typically only ONE of the two taillights and after replacement, it was solved.

One I spotted a couple months back..

It disappeared within 2-3 days... but it hasn’t rained and it’s been 90+ for weeks. Also my garage is 80-90 degrees in the daytime and is very warm at night. I’m just worried in a typical New England thaw/freeze cycle we can get pouring rain flowed by teens and 20’s. So it won’t have an opportunity to dry. I’ll keep an eye on it and mention it when I schedule the only other maintenance issue that I have (one of the rear seats doesn’t flop down without a slight push when I pull the switch in the cargo area).

I too have water in one taillight at delivery and SC said it was normal when a week later it was gone. It's since rained again and is back. I plan to mention it the next time I have to go in for some service, or after the MY quality increases. It's not acceptable and really looks bad.

An interesting thread. I must be blind or not very observant because in the 50 years I have owned various types of cars, I have never seen this problem. Sounds like some people have see this.

The manual mentions condensation can obscure the cameras in the ‘B’ pillars. They recommend turning on defrost and directing the airflow in the cabin towards them. So if you have a leaky roof on your house I guess you just crank up the heat in the living space so it dries out the insulation in the attic.
