2010 xk here with sunroof. Noticed today during rain that water is leaking out the passenger side grab handle, right out of the 2 rectangular screw holes with plastic caps. Any idea what this could be? I dont even use the sunroof for the channels to get plugged up. Also an observation, should there be sealant between the top of the windshield and the roof of the car? All I see is a big gaping hole. Appreciate any help, would hate to visit the dealer.
