Hello, I am brand new here. Thank you for being a wealth of information. A little background: I bought my 2020 Ram 1500 CC Bighorn from a dealer less than a week ago with 30k miles on it. We had some pretty solid rain since then and I noticed a few little droplets making its way through the corner above my rear window (under headliner is very slightly moist in that area). I have 3 very little kids back most of the time. My dealer said they will pick up and replace the 3rd brake light and replace the sliding window as well free of charge as one would expect after having the vehicle for less than a week. My question is should I even have them do this or could this just make the problem much worse? Should I try to repair myself using the silicone method(s) online? Thank you for any input. Obviously slightly bummed about all of this.
