It would be a good idea for anyone to look at this area. Like I posted before silicone or grease this area, if utilizing this to pass wires make sure it's sealed.

I still have leaking problems, I have sealed both of these grommets with silicone and did the sunroof grommets also. I used some old black coffee down the sunroof drains and I've not seen it on the floor. So the quest continues.

 

I think my problem is with the windshield not being properly sealed and not the grommets, it lookrs like the windshield wasnt properly sealed (had it replaced twice)

 

This is my last stop and a fear. My windshield has been replaced and the one it has has a crack on it. I can deal with the crack just not the leak.

 

Yeah I checked everything under the sun and nothing worked, replaced the grommets, checked the windshield grooves, checked the engine bay (sealed some things) and nothing worked. Looked at the windshield seals and looks like they didn't properly seal my passenger side because the driver side is sealed and it doesn't leak. So definitely because of the windshield I think

 

Sorry to hear you guys are dealing with this. My only recommendation is to seal the sunroof, at least temporarily, to rule it out once and for all. My sunroof appeared to drain just fine. I even had the interior ripped up while I poured water down the drain, but it all drained under the car every time. I've also stood there with a hose for about 30 minutes trying to get it to leak. Only during storms would it happen - odd stuff.

It's been about a year and half and I still haven't had a leak. It's wonderful not having to cover my car every storm.

 

Seeing this thread stopped in 2020. Has anyone figured out what the cause of leaking on the driver's side by chance? I am having this issue with my G25 (2012).
