GMC Yukon Denali 2016 - Water coming through roof while sunroof closed

[2015Denali4WD]

I have an 2016 Yukon Denali where water is leaking through the top speaker vinyl of my roof and pouring onto the dashboard and radio navigation area to my cupholders when it rains. My sunroof is closed during the entire time. I need helppppppppp.

Also I cant open up any doors to my truck with my key fob. I have to use the metal key to open the doors and the alarm goes off.

I tried starting it up and the truck said it doesn't recognize the key fob.

I drove it to work yesterday morning and it was fine. This is the first time it hasn't worked when it rains.

The shark fin antenna, no doubt.
There's a TSB on it.

I was looking at the shark fin and messed with it a little bit where water was coming out of it. What the heck do I do?

If you're in warranty that answers that, but if not, you'll need to drop the headliner and fix that antenna. I haven't read up on the TSB but I'm it's either a failed seal, or loose mounting nut.

No I'm not under warranty at all. I will take it to the dealer so they can take an look at it.

You should also check the sunroof drains. I have to clean the drains on my wife's 2001 at least once a year.
