My interior on my 2003 G35 sedan has been leaking water for sometime now, I am not sure where the water is coming from. I've attached a picture. Is this a common problem among G35 owners?
I am thinking it might be coming from the windshield or the moonroof, but would like to get an opinion before I start checking things.

 

You can probably start by cleaning the sunroof drainage system. My mom's Matrix had an issue with water in the interior floor. She took it to a shop and the just used an air hose to clean out the drainage track in the sunroof. No water ever since.

 

Agreed, you have a drain plugged for the sunroof. Might have started as a spider's web and got packed full of leaves and dirt.

 

Thanks a lot for the help, will check that out later today.

 

That was probably it. There was some slight black gunk inside the sunroof well. Took me awhile to find the hole *hehheh* , but after poking around with a small thin branch I was able to find it and clear it out. Now to wait until it rains again to see if it's fixed. Thanks again.

 

Got garden hose?
