I recently took a trip from Pa. to Fl. My 2012 GV ran flawlessly. The only issue was a puddle of water on the rear passenger side which appeared to be clean water possibly condensate as I ran the AC almost constantly for 9 days. By the time we got home the puddle had emigrated to the front of the same side. The carpeting was drenched but easily cleaned up. How would that much water get inside the vehicle?

It's most likely the aircon drain issue. There's a couple of threads on how to fix in right here in the forum. I tried various methods until finally fixing it for good by removing the dash and elimate the adapter between the drain outlet and the drain hose.

Thank you, Martin. My concern is twofold: The water started in the backseat area so I just checked the drain hose for AC.
It is in the correct location and dripping on the garage floor as it always has. Also this vehicle has been leaking for some time because of the rust under the carpeting. I am toying with the idea of selling it but it runs so well I hate to do it. Is it possible that rear wheel splash is the cause as both sides appear to have rust on the outside of the floorpan. No matter what I will have to replace the carpeting as the sponge mat underneath has sucked up the water like a vacuum cleaner.
Any other thoughts?
Thank again,
Dave B.

check the door drains, if blocked they may leak into the foot wells..

Check under the luggage area carpeting - I've had water leaking in on my third gen, I suspect through the radio antenna opening because it pools in the lens of the roof light at the back - if there's enough it may also possibly run forward into the rear seat floor area - in my experience, it doesn't take a lot of water to flow everywhere under the carpet.

I would also question the need to replace the carpet - remove the seats & trim, remove the carpet and hang it out in the sun to dry - I've actually removed the carpet from multiple vehicles, hung it on the fence and hosed it down, the crap that comes out is almost unbelievable. There is a fair bit of work involved, but no more than one be required to remove & replace the carpet with a new one.

Thanks 20. I ran a wire up the door drains and they seem clear. When I pulled the trim off the top of the rocker panels, it was soaked under them and the front one actually had splash on the underside. The wire looms are perilously close to water. I have blotted up most of it but the rust concerns me. this problem obviously has been going on for a while. Gettin' kinda worried.

Thanks Fordem. I checked the roof light and it was dry. Also tumbled the rear seats forward and checked for moisture. All dry including the luggage area. I pulled the little cover off the Luggage floor and it was dry as well. I guess I will get into the dash to look at the AC drain. It seems to be working but I am out of options.
Thanks,
Dave B.

My AC drained onto the ground at the same time it soaked the passenger side. I think you should have a good look under the dash where the drain goes through the firewall. Just because you can see water dripping under the car doesn't mean there's not a problem inside the car.

Martin,
You were correct. The sponge rubber "seal" at the firewall was just that: A sponge. Since I did not have everything out of the way to replace it I cleaned the old rubber out with long screwdriver and pliers. Dried it and packed it with silicone bathroom sealer which is supposed to be waterproof. Wish me luck.
P.S. I got under the car and blew air (mouth) back through the system. It was clear.
Thanks again,
Dave B.

Glad to hear you found the problem. Some have had luck sealing it with silicone, others have not. Good luck!

Thanks Martin. So far , so good. I have another issue that concerns me. My 2012 GV suddenly displayed the airbag symbol on the dash. I checked the A/B fuse under the dash and it is OK. The symbol stays on all the time. I checked both sides seatbelt lockups and they are fine. I even plugged in my OBD2 to see if a code would come up. No codes found.
Any suggestions?
Thanx,
Dave B.

Not all scanner will show codes beyond the OBDII mandated emissions..

You will definitely need a decent tool to read the SRS codes

OK I had my local repair shop use his OBD2 and no other codes than my unit. The only codes that show up are Engine and A/T codes. He also checked the fuse and connections under the seats. nothing unusual. My biggest concern is when I am sitting in the passenger seat and turn the ign to "on' the lower light reads "pass. airbag not activated" then shows the pass. seatbelt not on light. Of course the Airbag warning light is also on. What are these warnings telling me? Are some or all of my airbags not functioning?
Thank you,
Dave B.

All this means is that neither reader can communicate with the SRS controller. If the air bag light is on, the controller has sensed a fault, if the reader does not display it, the reader is not communicating with the controller.

fordem,
Thank you, but if the airbag light is on does that mean that the bags are not working? Or is it just a sender-reader error?

It will depend on the severity of the fault, it could be just one airbag, it could be all of them. Find a decent diagnostic shop that can read SRS codes and find out exactly what's going on

You'll know the answer to that question when you know what the code is.

There is a safety recall in the US for the passenger side cushion assembly to address a problem with the occupancy classification sensor. This only applies to the leather seat trim specification. If you have these seats, and have not had the recall repair done, that could be a place to start. Other things that come to mind are; if you happened to disconnect the passenger seat SRS harness with the battery connected that could set a hard fault code. Also, you mention water on the passenger side, it is unlikely but worth checking to see if there is water / corrosion damage to the pass side SRS wiring. This is all guesswork however, as already noted a scan tool that can read the BCM codes like a Suzuki SDT or an advanced aftermarket scan tool like an Autel 906BT or similar will be the way to really know what is going on
