Water under the floor!

Hi all. Brand new here (and to Jeep). Just purchased a 2012 Grand Cherokee on December 23rd only to find the under floor area FULL of water when we got home. Of course the dealership was closed over the holiday weekend so I had to drain the water out myself. I drained both belly pans of about 7 total gallons of water and the back deck under the spare tire had to be soaked up with towels - it was about an inch deep back there. It has been in the shop for a couple days now and they can't find anything definitive that caused this. To say I'm concerned would be an understatement. does anyone have any insight? All 4 sunroof drains were clear and running out of the vehicle properly. All door seals appear to work properly. The windshield doesn't leak. What the!!!??? :confused:

Check the a/c drain line - I remember seeing another member post about something similar. If there was that much water in there the small amount in the spare tire might have just condensed there over time.

Seven gallons is a lot of water. My guess is that someone at the dealership left windows or the sunroof open and rain got in. If it doesn't happen again, that was it.

Thanks, guys. Appreciate the messages. I did return the vehicle and am looking forward to receiving the replacement. It is a great vehicle, isn't it? Im going to throw that first experience in the fluke bin and try again. I sure enjoyed my short time with mine (other than the stress caused by the water issue that is). They hooked me up with a 2011 GC rental so that's cool too. Best wishes and thanks again.

I can appreciate your skepticism, armoredsaint. I wouldn't have believed it if I hadn't seen it with my own eyes. I did take pictures that may lend some credibility to my account of the event. Either way, some might be interested in what I saw.

Picture 1 is of the spare tire storage area beneath the back deck
Picture 2 is the battery storage well beneath the passenger seat before I drained the area
Picture 3 is the first of two buckets that I filled to about 3/4 with an aquarium siphon before I located the rubber drain plugs (sure wish I had found those before pumping all that water by hand)
Picture 4 is the water flowing from the driver side drain plug

Appreciate the link, WoodKnuckle. I happened to stumble across that service bulletin myself over the holiday weekend and forwarded it to the dealership service department. As of this afternoon, after a total disection and inspection of the interior, a definitive cause of the pooling water could not be found. I'm thinking that it was left open (the sunroof maybe) out of production. Rain entered while it sat outside and collected underneath. The water was allowed to spill back when the vehicle was loaded onto an inclined transport trailer explaining the water under the cargo area. I'm certainly no detective though, just a guess. Anyway, I'm glad I'm getting a different vehicle. I worried about long-term implications of all that water sitting for who knows how long on who knows how many critical components. :thumbsup:

I believe I was the original poster back last year when I had probably 15 gallons of water caused by the ac drain line never hooked up I kept the vehicle because they pulled all the carpet wiped it down and replaced all the carpet and padding with new ones,never had the problem again,I did however trade it in this past September for a new 2012 overland summit.

My daughter has a 2012 JGC and swears she hears water sloshing sometimes. I have checked under the seats, spare tire area, ac condensate drain and removed the rubber plugs under the car. Bone dry! Sunroof area looks good. I cant reproduce the sound and have check every entrance that has a seal and all look good.
