Infiniti G35 & G37 sedan passenger sunroof drain repair

Updated 12/27/17 - I've been asked this a few times so I want to update those reading this. The repair has been a success the last few months staying dry in Florida rains. YES!
This video is to help those with Infiniti G series sedan passenger sunroof drain leaks or with water leaks of unknown origin on the passenger side. It goes through repair steps and symptoms.
2007 Drain plug part number called "Plug-Side Trim" online is 74816JK01A which was superseded by 74816-JU40B. Cost is around $15 online for a factory part.

A little late to this party but I just completed repair of both driver and passenger side plugs in my 07 G35x. I have minimal experience working with interiors and all together this took me 2 hours. Couple thoughts:

[@jes0lis]

Dont forget BCM on passenger side . It will get wet and/or the fuse box lower left driver side. Car wont have any power but will unlock. But seems completely dead.

I had tons of water on the passenger side floor with every rain... this fixed the problem. thanks!!

[@mauricechesire2067]

Thanks Braden! Your video was very helpful and helped me fix my G37. I liked the tip on using hose clamps. The dealer wanted to charge a lot to fix it. Great work!

Before finding this video the leak in my sunroof has been going on too long that it fried a $1200 component that cost me total $1500. I just kept the old part and cleaned it up along and flushed the tube from debris. Did a test with 3 cups of water to ensure it came out to the ground, SUCCESS! THANK YOU FOR THIS VIDEO!

a very complete video- thanks - good job

[@Roeheyleo]

Great vid! Didn’t know the plugs could be purchased from the dealer so thanks for providing the part number!

The best fix is to reroute the line into the a/c drain located under the passenger side floorboard carpet.

Thanks for the video. I did away with the plug altogether and just extended the drain tube by using by using a 3/8 nylon hose splicer and about 6" of 3/8 in inside diameter 1/2" outside diameter tuning. I zip-tied the hoses to the splicer and then pushed the hose down the firewall through the hole intended for the plug. So far it works well and only cost me $6 in parts for both sides.

Thanks for this. My car is at the dealer right now, charging me $350 for the $15 part (including install.). I am of the opinion that this type of thing really shouldn''t happen for what you pay for this type of car.....

[@loprueboporti8373]

good video, a little to much detail when you only have 1 hand to work on what you explain; but beside that really nice to let us know we have a hope for our really cool infiniti's car. My mechanics was for 3 hour checking all and we look in some answer in google but we didn't got to your video. my car carpet is off so the water can dry. after we blow air thru the sunroof holes where the hose are connect it, we have some water coming more easy than before but i think to really fix this issue i will have to do what you show here.

Thanks, Braden!! This was hugely helpful and saved me from unnecessarily replacing the windshield (which my mechanic thought must have a leaky seal prior to seeing this solution). Great work and thanks much.

[@kosavanh2431]

thank my is leaking from top run down to side of door both side n flood front n rear froor i m working on right now

[@UnnecessaryPurchases]

I’m having same issue in my 2012 g37x sedan and wanted to confirm it’s the same part number I need to order

[@TheApeCeasar]

I just bought a 2013 g37 and 2 days later it rained and my drivers seat was soaked gonna try to do this myself wish me luck

[@yugihlh]

I don't get why Infiniti doesn't fix this issue

[@gustavedorantejr4372]

So i have the same issues also got the part from the dealership brought it to the shop guy kept saying it was too small and the factory one wasn’t clogged he used the air compressor to blow the gutters but I noticed i still have a small leak I think it’s going from the groomets cuz the other side had a small amount off water mechanic probably just didn’t want to do it

[@tailoredsuits]

Can you come do mine please ?? It just started in passenger side. Dealer said 1800 to replace all the tubing. I have a convertible. 2012 but only 30k on it. Only drive in summer.

[@taoye5659]

I am having a similar problem. But I have a 2008 Infiniti EX35. Wet floor on front passenger side. Anyone has this problem? Should I replace the same part?

[@atsygulev89]

You should have moded the plug by breaking the inside diffuser (little plastic thing sticking up on the inside) then added a plastic tube through the hole. Everyone with this problem is doing this mod, otherwise get ready for that crappy gasket to break down and wear down and then bam more water by your feet again
