Leaking OnStar Fin

[crowagAT4]

I've had my '21 1500 AT4 at the dealer three times now for a leaking OnStar fin. First two times it was leaking via the microphone cover, now its leaking from the connection point where the sun visor connects. Really frustrating. Anyone else have this issue?

I run a bead of black rtv silicone around it on every truck, when new, ever since my first one leaked in '15.

Good to know, will likely do that myself now.
