Anyone had water getting in right around this area? Ive redone the seams and sealed around the rear window very well just to make sure it wasn't the rear window. I'm baffled. Any help is greatly appreciated.

 

Your sunroof drain hose is in that area, so you might want to check it if you haven't already.

 

I have had some leakage on the left side in that area and used some silicone caulking around the channel and it fixed the issue,

 

Lay in the trunk with a flashlight with the lid closed. Take pictures. Have someone pour water with a hose without a nozzle that you trust to let you out. How is your rear window rubber weather stripping looking like? What else could it be?
