Love my 2019 Denali but couldn't believe my eyes when i came out this morning and saw water on the back passenger side seat. 6 month old 65K truck and it leaks!!! Did a quick search and found others with the exact same problem and the exact same location. Will be calling service center in the morning. Here's another one I found. I took videos and pics if anyone is concerned what to watch for.
My son is allergic to mold for me this problem is larger than most. Attached a pic of the headliner, can see how soaked it gets.
