Water leak from gps antenna

Does anyone have issues with a water leak when it rains on drivers side by sun visor from gps antenna on 2016 sierra Denali

This is extremely common. I've put a ton of these on because of the crappy seal on the bottom.

It's almost like a felt type of seal. It doesn't feel if any decent quality. But they come paint to match when your order them. Or if you're out of warranty, you can remove it and make your own seal. It has a non-reusable clip on the bottom of it. So you may have to buy one of those. That of which I don't think you can get separately. You'll have to check with the parts dept.

thanks for the info , I took it to the deal for them to replace it because it's still under warranty

It's just frustrating that this is the second one in a month

Yup, go over to the recalls and troubleshooting section. You will see my post, and several others, with this same problem. It's the inner seal in the sharkfin antenna. This is a common problem and apparently the service depts know it all too well. Surprising it's happened twice to you. I have seen some have a leak at the windshield in that same area so that may be the source of your second leak. Could also be sunroof seal.

Here's a link to the troubleshooting area. Happy reading regarding this problem.
