Ok so I want to put a post together about the onstar, XM, sharkfin, and whatever else antenna we have on the K2xx platform. I know there have been water leaks plaguing all years from 14-18. All the posts here I have seen, don’t really have any info or “the dealer fixed it”. A lot of people have commented that there is a break in the seal in the rear of the antenna. Please understand that is not a water seal for water intrusion into the cabin. That is only a rubber trim from the plastics of the antenna to the metal roof skin. There is a foam seal that goes around the wires and the mount that does all of the sealing of the elements. When the foam seal deteriorates is when the water issues start. I will explain with pics a little further down in the post. So I have a 14 Denali, vehicle was Daily driven, until 2 months ago, has 90,xxx miles on it, sat out side during the day, and garage kept at night. I have never had any water issues from the antenna (or the 3rd brake light for that matter) Here you can see the square seal around the home in the roof was still sealing with no issues One of the reasons this post happened was because I found a color matched shark fin brand new for VERY cheap. And my Denali has the black plastic fin from the factory.
