Infiniti G37 Sunroof Drains Leaking Again - PERMANENT FIX!! 

I had this same issue with our 2012 G37 sedan. Water on both sides, front and back. Sucked a whole wet vac amount of water out of it. My dealer quoted almost $1,500. Drop the dash and would not install a modified part. I am not even close to being considered handy but I watched your video, purchased some 12 inch screw drivers and same length needle nose pliers. I modified my drains with tubes and did the install in one afternoon. It tests perfect and no leaks. I cannot thank you enough for taking the time to make this video. It saved me money and showed I can do repairs with the right instruction and tools. Many thanks!

So glad you came back to bless us with one of the best step-by-step videos for our specific cars. An absolute blessing you still make videos for us.

I just tackled my passenger side today and your video was a total godsend. Thank you thank you, very annoying problem with these cars and I was at the mercy of the dealership

Truly appreciate this video.. Ive had the G in the garage 2 years now.. Only take it out when there is not chance of rain

At my age I can't take this on myself, but understanding the issue may help me with getting it fixed by my trusted garage. Bought the 2011 Journey two weeks before the tsunami, with 94K miles now I hope it's my last car. Thanks much for a clearly explained assessment and remediation.

I did this and now fixed. Thank you King!!

Thanks to you, I solved a problem I had been worrying about for a long time. Thank you very much.

Damn bro. I’m not sure if you goin by Alex still, however, I just wanted to thank you😇You are an inspiration man and I know this is a regular upload, but it’s good to see you return bro. I’ve had a couple cars since then and I’ve always admired both the Z and the G. I came from a Base 5-Spd MK6 Jetta to a Q50 3.7 S (had it for a year now). I’ve always admired and respected your videos and I can’t wait for more! Hope to see more of your content!

I saw your previous videos, thnx! I did it last winter with a ballpoint pen. Also an important thing is a pliers. I bought it because without them it was problem to get it off and get it on. That leak is a big problem. But we solved it!) Best wishes from Kyiv, Ukraine 🇺🇦

I did this last year with a plastic straw from a kid’s cup. It has been working perfectly ever since

Your previous vid was my go to as it was the most detailed and actually had better camera angles to see what needed to be done. Though I did buy a new one and used an empty pen shell to mod it. It stopped my passenger side leak and has been working for the past 8 months; definitely better than the $1.2k I was quoted at the dealership since they said they would have to remove the entire dash. Glad to see you uploading again as you and motorvatediy are my go to G guides.

The fix is actually easy. Remove the A pillar and remove the tape that's attached to the hose. Stretch the hose forward to give some slack. That's all. What happens is the hose shrinks over time and tugs on the drain plug. Or go to Home depot and get some hose and extend the hose going to the drain plug to give it some slack. Got a foot long needle nose pliers and a flash light and I had mine fixed in about 5 minutes.

Thanks so much. Extremely helpful. I tried using needle-nose pliers but ended up using my hand, despite my wide palms and small fingers(sorry, ladies). Going back in was incredibly annoying, the insulation in front of the hole almost broke my brain until I just jammed my hand in there and then it took two seconds

Nice video man. I just bought my G and had the same issue. I did everything exactly as you said and it only took about an hour for the passenger side drain. It was the perfect fix. Thanks a lot for making this video!!!

excellent suggestion. thanks for this video

This happened to me as well, was a pain in the ass. But what I did was just delete the baffle and re attached the hose onto it and I haven’t had any problems since, and we’ve had some serious rain up here in NYC.

If you have water in the car, I find that the best way to dry it out is to take a home dehumidifier, get a board to put underneath it to protect your seats, use a blanket to get the board level, and run it for several hours with the cord coming through a narrow crack in the window.

Thank you that's a good idea man, my car have the same problem

Good video man! I’m hoping to find a way to get the headliner down because I must have yanked the line loose up top causing another leak 😅

Thank you I'll be trying this.

Only this, is going to work. Thanks !

Hey guys I went to do this and found out the LEAK was ABOVE my battery. I used sealant to seal the cowel above my battery. Seal the space between the cowel (plastic cover) and the windshield wipers. You will see that the opening for the interior air filter is right under there. I had my windshield replaced and they did not seal the cover properly. Try this first, I spent a day and this was not my problem. 😢

Can we have an update man? Is it still holding up? I purchased some 1/4" copper tubing, so hopefully that fixes the issues. I appreciate your ingenuity.

Aye ive been needing this.

Thanks for the heads up! I’ve had my 2010 g37 sedan for many years has not leaked yet but this is good idea for an issue I didn’t even know about. Looks like I will be taking my car apart soon since I have some aluminum tubing, flaring kit & some left over rtv sealant. I will also add some to that foam/ rubber ish cheep so called gasket. If I made the exit tube through the firewall a little longer would that hurt anything?

I just siliconed the sunroof told my gf not to buy a car with sunroof now she understands 😂😂

Thanks, very helpful

Thank you!!!

I had this problem. Car's computer went nuts with water all over it. I finally cut the front passenger side drain halfway up the A pillar and folded it over, and double zap strapped it. Then I filled the same drain hole in the sunroof with silicone. No more problems.

I had the same issue with mine and pondered taking it to a sunroof specialist with their own shop. It took a bunch of looking to find someone willing/able to fix sunroofs. The sunroof specialist charged a couple hundred bucks to just diagnose the problem. I found a mobile sunroof specialist who came to the house and fixed it in the driveway for about $200. He ended up extending the drain line down to the rocker panel and was done in under an hour. He sees the same issue with Nissan/Infiniti and fixes a couple a week. It’s been four months and ton of rain with no issue. Just look in your area for a mobile sunroof specialist.

Will be trying this

I wonder if this is a recall issue? dealing with this rn looking for someone to fix it thanks for the vid

I was able to push the whole pics through to the other side of the fire wall… works quite well 😂

Is that grommet visible from the other side? Say, if you pull back on the fender liner, can you see it?

Went mine was leaking about a month ago I got rid of the yellow piece completely and added a size bigger hose and clamped with zip tie then rerouted it behind the glove compartment to underneath the floor trim and through the ac water drain hole. It fits right in there no issues since.

Car went into limp mode a couples nights ago when i was headed to work. No cel, codes, etc. My sunroof just started to leak a week or so ago. We had a bad storm that day and i assume it just got my bcm a little wet. Luckily the next morning when i got out of work it was fine

Im having the same problem where sometimes the car will not start at all after driving it to the mall. but my friend told me that there's another drain hole near the wiper blade? is that correct too?

Good afternoon Kova. Where is your workshop located? I live in new jersey. I have an Infinity 2012 G37X I have a leak in the sunroof I have done everything possible I even did the procedure with liquid plumr gel and everything flows very well the water came out in the correct place as you explain in the video but you still have the problem with the leak Water falling on the passenger side. I am desperate with this problem. I don't want to take it to the dealer but I don't know what to do with this problem. I did what you explain in the video and nothing. Thank you. Carlos Castillo

Hey man. Is it still holding? Thinking of doing the same but I am a bit concerned shrinking the diameter. Is the flow enough not to return inside ?

I ordered some straws but the diameter was too big to fit into the plug. Can you share with me the link to the exact straws you bought please

I got the drains out, but know can’t seem to get them back in. What type of problems could arise from me just extending the hose and sticking it through?

Yes but what metal tube you use , size where to buy infoo

Bro did this really fix it?? I think I have the same problem same car and living in fl it’s raining rn after Ian my car was glitching out.

I fixed both sides and still have a leak... Could this be the reason why all 4 of my windows roll down on their own while the car is off and parked?

I’m thinking about drilling a better hole and jb welding a 3/8 inch metal piece

Does anyone have a suggestion for upgraded sway bars for a G37x sport sedan?Appreciate it.

Has it stayed 'fixed' now a couple years along?

I have a leak on my drivers side.... only when it rains the carpet gets saturated... def something is clogged need to fix it.

Knock on wood. I have not had an issuse with my M37X. But when I had mt SS 07 impala sure had this issuse. . And uea that BCM on passenger side floor had my go bad with water leaking from a not so good seal from windshield change. Corrode the wires and bcm. Lights and alarm would come on and off when parked drained two batteries in one year glad it was under warranty. Over 7k for harnesses 3 month back order from Japan.

what is part number for the sunroof drain adapter?

I want to first try a wire snake from the sunroof track down towards the bottom but I can't even find the drain holes! Does anyone know where the drain holes start?

Think i have this problem. Got a feeling it damaged my ecu. When i bought the car i didn't realize the roof had stains. After a year. It's getting worse

I hay size straw did you use?? Drop a link?

It’s raining in LA and I didn’t think it would happen to me 🤦🏻‍♂️ passenger side has a little puddle

There should've been a recall on this. This is a known issue. & the leaks typically hit the electric wires on the passenger side smh.

Am having the same issue, if I do this method how long will it last???

Just came to say, this fix worked for about a year. Will be doing btr fix now. Adding hose to both sides, and routing it to ac drain.

What’s wrong with just cutting the baffle out and leaving it like that?

I have to bite the bullet and do this, too. I'll try the metal straw route. My only concern is corrosion over time versus a plastic one.

Had this happen to me earlier this summer. I replaced it with a new one and took out the stopper thingy.

I was wondering why I didn't see any videos on snaking the drain hole first. Now I know why. I have a leak on the front passenger side only. Confirmed it wasn't draining from underneath the car. Then I snaked it with a brush tip wire and degreaser all the way down to the firewall and followed with hot water. It started draining great so I assumed I got lucky. No, although it's draining outside car it still also leaking inside as well. I guess it's safe to assume the hose leading to the firewall plastic cap seal is shot?

Hey are they sunroof drains going into the rear?? Or just the 2 upfront?? 2012 g37x

Is there a drain going to the rear? I have been getting a wet floor in the rear passenger side. 2011 coupe. And if so, is it a similar fix?

Hey I have a 2009 g37x coupe, my interior lights have stopped working, my steering tilt, and my seats do not moving anymore? Can you help me out

Bro nobody shows the location of the actual plug piece its always just in their hands and then boom back in the car 😂

Haven’t gone this route. But I’ve heard of people still having this issue even after doing this. So curious to know if this has solved your issue @Kova.

Great workaround. How many sunroof drains are on this vehicle? I have a 2008 Infiniti G37 and am encountering random mold issues (can't tell where it's failing exactly but highly suspect it's the sunroof.

Would water still get in if you don’t use the sunroof ?

Has it leaked ?

@Kova has your G leaked since you did this modification?

So this is what im confused about, my passenger floor board is filling with water but if my sunroof is closed water wouldnt be draining down through those drain holes during a heavy down pour would it?

I’ve been wondering what’s causing water to leak to my passenger floor I can’t lie tho I’m not too car savy should I take it to a shop to have it fixed for me?

Can the leak happen in the back seat?

Did this work for you? Also where did you get those needle nose pliers from?

I just did this with a plastic tube but still getting water. Prob not from sunroof since I believe this technique worked best, but it looks like from the side window near the corner. Water leaks right down over the door tweeter and leaves a pool of water under the Styrofoam baffles under the carpet. Anyone have this issue? I prob need new door seals but there are so many in that area. Afraid to take to dealer as they will prob want to replace everyone at like $150 each. There is like 3 or 4 total per the parts list. I was thinking of starting with just the long one on the body of the car that seals the frameless window. Any thoughts? Very disappointing for a lux car

can I buy a pair from u

Mine just started leaking again today🤦🏽‍♂️

TEST IT BY RUNNING WATER ON IT

Definitely good for the passenger side but does anyone got a fix or atleast a walk thru of the driver's side?

My damn g leaks water

The Dealer wants to charge $1140.00 for this problem

This is ridiculous I got rid of the Infiniti got into the Lexus it’s definitely a better sunroof

If the bcm does get wet from this issue does it get destroyed?

I think my concern is what happens if a spider decides to crawl up in there and make a nest inside that tube? You will end up with the same problem all over again. Except this time it will leak in directly from the moonroof.

Okay but ur a lifesaver 🥹

Thank you!!!!!
