That's exactly what I did. Silicone sealer around the XM antenna. When it sat with 4 inches of snow and ice on the roof, a few drops came thru. Dealer said he will replace the XM antenna gasket, no problem. I just didn't want the service dept to drop the headliner. Since I sealed it about three months ago nothing has came thru, knock on wood. Had more snow and ice on it and took it thru multiple car washes and nothing.

If anyone can help, I'd sure appreciate it. 2016 2500 6.0 gas. Sometimes, (not always) when after shutting off my truck, it gives off a high pitched whistling noise. Sounds like a tea kettle boiling. Not constant, off and on. It starts about 10 or 15 minutes after shut off. Not always, just occasionally. Coming from under hood but I can't pinpoint it. Dealer says it's some electrical items shutting down. I'm sceptical on that as it doesn't do it every time. Sounds like the truck is sending morse code in a boiling tea kettle sound, lol. Anyone else heard this noise? Thanks Gary D.
