I had that issue back in 2019. It took several trips to the service department to get the tail lights replaced. At first they couldn't reproduce the issue. Then I was a le to bring a photo of the right side with condensation and they replaced that one. They wouldn't replace them both without proof or reproduction. So, after the next time I washed the car I got a photo of the left side and then they replaced that one. I haven't seen the issue since then. They were replaced under warranty.
