Water leaking into cabin on the drivers side
 

I keep getting water build up on my driver side under my carpet and only on the driver side. Has anyone had this issue before? Or any ideas what could be causing water to get in the my 2012 370Z.

Have you tried looking under dash for water droplets maybe on wires so you can trace the leak. Where on carpet does it start, high or is it only wet at the floorboard?
Maybe the AC drain is clogged.
How long have you had the car and how long and often has this been happening?
And if the370Z.com can't help you no one can.

Yea its only on the floorboard I've had it for 7 mo. and this is the 2nd time its happen. I had found a whole on the floorboard the first time cause the guy who owned it before me had led lights under the car and was running the wire through floorboard so I cover it thinking that was the issue.

wow, he ran it through the floorboard? the f-... :shakes head:

i would assume he made more holes in this case.. :ugh2:

Check the rubber gourmet on the driver side from the hood and see if it loose. It happened to me before.

Mmmmm...Rubber gourmet

Look for more holes and make sure they are sealed. If you have nice, round holes, you can get plugs in many sizes. Otherwise, RTV may be the answer.

Check the firewall and make sure all the seals are intact (and that the OP didn't poke a few holes).

IIRC, the A/C drain is on the right side of the car and shouldn't be the problem but I'm not 100% sure. FSM will have drawings and descriptions.

After sealing all the holes/leaks, make sure the carpet and padding are completely dry or mold/mildew can get started.

Do you have an amp in the car? If so, the previous owner may have run that wire through the big grommet on the driver's side of the firewall. Make sure it's sealed.

this is why i never by used... you never know what you're getting or how it was really taken care of... bought a used "newer" car at 18... it soaked me... i've bought/leased new ever since

best of luck to you op... that really sucks :shakes head:

:rofl2:

I've had water come through my drivers side window at the car wash before with my windows all the way up. I'm absolutely sure the windows weren't cracked at all. It doesn't happen every time but has on a couple occasions. Not sure how or why

Your windshield has been replaced. That's the cause 90% of the time

78% of all statistics on the Intertubes are made up on the fly. :p

But, yeah, that's definitely worth looking into.

:iagree:

43% of all people know that

I am 67% sure you guys are right.

yes Threadlocker I do have amps I'll check that thanks

Good luck man! Hopefully its nothing else you have to try and patch up.

Well if this Z does survive 20+ years of service, someone is gonna need to weld in a new floor someday.

Unless you take care of it now. Clean, dry, rust eater, maybe weld a small plug in primer and paint.

Edit: 50% chance either of these two happens

Most likely your A/C drain is clogged. This has happened to me in multiple cars I owned.

You scumsssssss! You forgot to mention the door also has seals, including around the window, that could also be a possibility. Check all the simple stuff first. Had a few buddies that had to replace them. May not be your problem butbid check them for holes or tears

Not digging threads intentionally, but...

The wife's 2010 roadster convertible (totally original) is taking on water ONLY on the drivers side. After getting it all dried out (wet vac, towels) I had her sit in it and blasted it with the water hose for 30 min. No sign of leaks anywhere. With the car sitting in the same spot, it started raining again overnight. Driver's side floorboard behind seat is full again. :icon14::icon14::icon14:

Has anyone experienced this that hasn't cut holes or made other mods?

Sounds like it might be a leaking door or window seal. IIRC, there is also a seal behind the B pillar finisher.

I have had this issue on my coupe. its been back to Nissan several times. I keep ending up with wet seatbelts...

Wet seatbelt sounds like a problem with the B pillar finisher. At least one thread on the subject.

Roadsters dont have a B Pillar. Ishtim, heres a diagram of the seals for the top. Check #17, 18 and 19

Thanks for clarifying that. I didn't notice it was a vert.

I certainly will as soon a s the wife gets home... Am I looking for tears or what? I looked at it briefly yesterday and didn't see anything odd.
Thanks for the diagram BTW. :tup:

I would look for tears, even small ones, and if the rubber is dried out. Check how the seals sit with the top closed. Clean the seals if theyre dirty. Also, that vinyl strip that protects the lid, that could also be a source of a leak if its rotted.

Sit inside and have your wife spray down the car and see if you can detect the leak. Curious, do you use high pressure when you wash the roadster?

Thanks again... here's a follow up: After a rainy day, water again pooling behind seat when wife got home. Drivers side floor (under mat) slightly damp but firewall and all other vertical surfaces dry to touch.

I opened the top about half way and did a visual inspection of the seals starting with #17, 18 & 19 around the window as suggested. I didn't find any tears and everything still feels soft & supple (garage kept since new). I wiped down all the rubber with a damp terrycloth towel (some had light traces of dirt) and did a closer inspection of the "tub" that the top folds down into. It looked dry. The only suspicious thing I see is the vinyl "sticker" that protects the painted surface from the canvas top's seal. It looks like it is starting to bubble up in places, but it is on the outside and it seems that any water would find the gutter under the trunk lid and drain out towards the tail lights. I wasn't able to sit in the car and have the wife spray the car with me in it yet, but its still on the to-do list. Now that I've cleaned up the rubber, I'll check again tomorrow evening. We are supposed to get rain all week. :mad:

FWIW, car has never seen a pressure washer nor a drive-thru car wash.

Theres a couple videos on that thread. :eek:

Invest in a car cover asap.

But that should not be the ultimate solution to this problem.

I opened top halfway, wiped down all rubber seals with damp cloth, checked for cracks, pinches or other obvious seal failures and inspected the "tub" and the small open areas where the top sits when opened and found nothing.

We then made several failed attempts to locate a water leak via the "sit in the car while spraying it down" and after receiving responses from local shops not wanting the work, the wife dropped her 2010 Z at the dealer yesterday and picked up a Versa :rofl2: as a loaner.

I'll report back...:horse:

I hope they find where its coming from!

Is the top down when it's raining?????
































j/k:p

Did you found the problem??? Because i also have this so now and then

Yes. (but not sure I understand) The Nissan dealership claims that a "bow" in the top is defective. They also said that parts to repair the top are no longer available and could not do the repair. Contacted Nissan Consumer Affairs, they said they couldn't do anything to help. Wrote dealer letter asking for guidance with the repair... That was a week ago.
Unless there is a positive (is some way) response, this will be the last Nissan for us. We've had 3.

Defective? In what way would a defective bow allow water into the cabin? Does your top open and close properly (aside from the 5th bow hitting the lid).
Thats a piss poor explanation. I would ask them to be more specific, and if they cant or wont, report them to Nissan and Consumer Affairs. It sounds to me they couldnt find the problem and just giving you BS.

A vette lady next door said it might be water coming thru the cabin filter if on passenger side. If it is the part they say I see many part outs on the forum & buy that piece:tiphat:

As soon as I get time I'll post the history of issues we've had with the top.

@bunk asked if the top opened and closed properly. It did new, then started to stop halfway. We brought it in to the dealer (while under warranty) and got the "Yeah, we fixed it... but then it wouldn't open again weeks later, I (and Nissan) have a record of everything done with the top.

Latest response from local dealer (after three emails and three weeks) to get a "hint" on the diagnosis.

In all honesty the top has been lowered/raised MAYBE 50 times and the car is garage kept w/ 100K miles.

Look into your state's Lemon Law.
