Hi there, I also have the same problem with water leak, I have a 2002 Sienna also, and have been in talks back and forth between the dealer and Toyota Corporation (800-331-4331). The thing with mold you can't get rid of it completely, especially behind the carpet is a spongy material, it will always stay there, you have to replace the entire carpet. Just spoke with my dealer and they want me to pay for it ($2100) yes...ouch!!!!)
Listen folks, this is without a doubt, a manufacturing defect and a severe health issue, and they are refusing to pay for it. We are talking about a serious health issue here, in some cases it sends people to the hospital if not death. That's why I am standing the ground and making these people pay for it, IT'S THEIR PROBLEM AND YOU SHOULD NOT PAY FOR IT.
I've noticed a patern, they all deny that the problem exists with other customers, here's the classic -"nothing is in our database about this problem". Then why in the world Toyota re-designed the rear hatch seal????? ( maybe they were just boured...and woke up one day, "hey, lets design something different today!!! WOW!)
I had this leak problem since I bought the van 2 years ago, now it's unbearable smell of mold and rotting smell of death! I've had it with this people, if they don't fix it I am taking them to court. Guess what, they will pay a lot more than a mere carpet and a seal! Please contact the Toyota Corporation at the number above, if enough people make noise, maybe, just maybe, they'll do something. Please pass the word around, these water leak problems that I've read in posts similar to this one, reports problems from years '98 to '06. I feel bad for these folks, because they are stuck with it and not knowing what to do. (You would think, that the great TOYOTA would help you...NOT!) Hope this helps.

YES , they should take care of it.It seems the dealer isn't too good at diagnosing
it and the problem lingers on.it took acouple of years of this reacurring problem to get bad enough where i had to have someone else diagnose and repair leak from rear hatch.hanging carpet out to dry,and spraying with lysol the floor and carpets nuetralized the odor.i did notice with the carpet removed up in the front floor boards,area's rusted from this since ,off and on for awhile i noticed a odor,musty
and moldy at times,little did i know i had water below my feet.
well good luck with getting Toyota to step up and Fix.
LET US ALL KNOW HOW YOU MAKE OUT.
#41 of 128 Leakage from rear hatch
May 25, 2009 (7:19 am)
I have yet to find the time to get the rear seal fixed. What I HAVE done is I've pulled the carpet out and put it in my shed to dry out. I the meantime I put the carpet mats back in. You almost don't notice that the the carpet is not there. Now when it leaks it doesn't get trapped under the carpets and it dries and doesn't get moldy. I know its a short term solution but its getting the job done for now.
I cannot imagine ever getting the mold smell out of the carpet so even after the rear seal is fixed I will probably leave it like this until you guys convince Toyota to pay for new carpeting.

I have had a similar problem. Over a year ago I was hit from behind and had to have the rear bumper replaced. Starting last summer the inside of our van started having a bad smell. I attributed it to 3 kids and 8 years of use. This spring the front driverís side carpet became soaked after heavy rains, following by the front passenger side.
I went back to the body shop that replaced the bumper and showed them that the back door was out of alignment and that water was leaking in. They fixed it. I then removed all the seats and the carpet and found that the entire carpet was soaking wet. While we are drying it out, it appears that water is still getting in somehow. I am not sure where to look next. From this thread it appears that it could be the rear AC panel. Did this finally fix the problem for you?

Yep same problem. I had purchased a used 2003 Sienna. I use it for craft shows in the winter here which is a dry season. Van had been sitting in the drive for 3 months and I just pulled it around to get ready for "season" and found it soaked in the front, both sides under the carpet. Pulled out all my display and sure enough the back was damp too though the front was REALLY soaked (its rainy season now, raining almost daily). Too much mold already so I removed and tossed the carpet, figure since the seats are stored in the barn anyway, I'll just throw down plywood as a floor. Had my SO run a hose over the vehicle and sure enough the water was coming from around the liftgate weatherstripping, and draining toward the front, underneath the carpet.
To all, correct terminology is a great thing when searching for parts and infromation. Its a liftgate, not a hatch or a door. Its not a seal, its a weatherstrip. The weatherstrip can be located online for $60-$70 and replaced by yourself. You can buy a reasonable replica of the carpet on ebay for about $250, and if you've already torn it up, you know it won't be that hard to lay down. Most important thing to worry about is how to correctly disengage the airbag system so when your fiddling around the front seats, replacing your carpet, you don't blow your airbags.
#44 of 128 Mystery leak in Cargo area 04 Sienna
Sep 14, 2009 (4:50 am)
I have a 04 Sienna and I am the original owner. Water leaks for approx last two years. I'm not sure how it's getting in and pools in the back area only, after a heavy rain. I have taken it to the dealer twice now and it is still a problem. The back padding is destroyed and the bolts which bolt the rear seats are rusted. The first dealer visit was a couple of years ago and they said it was the moonroof, not resolved...The last dealer said all the roof rack seals needed replacing 300 some bucks later the water is still coming in that back area. I'm thankful for the info in this forum and am hoping to resolve the leak with some of this information behind me. Off to the dealer today..again. I'm thankful it has finally rained here in San Antonio but not for this AGAIN....

SINCE IT DOESN'T RAIN MUCH,THE DEALER,BODYSHOP SHOULD BE
ABLE TO PRESSURE WASH VAN TO SEE HOW WATER IS GETTING
INSIDE.EVEN THESE NEW CAR WASHES THAT USE HIGH PRESSURE
WATER(NO BRUSHES) WOULD BE STARTING POINT TO LOCATE ENTRY
POINT OF WATER,REAR HATCH PERIMETER SEAL IS A KNOW PROBLEM
AND WATER WOULD LAY IN BACK,SHOULD BE EASY TO LOCATE LEAK WITH A PRESSURE WASHER.

Sorry I took that long to respond, just in the last couple months I have come to the bottom of this problem (at least I thought) and I know a lot of you are anxious for the fidings so here is:
After countless trips to the dealer, (I told them next to that, I will move in, set up my sleeping bag right in the showroom) they decided to pay to replace the entire carpet and door hatch seal (this seal goes on the body of van in the perimeter of hatch door) their cost of $2,100 (sorry I really don't feel their pain...) after job was done , they were very proud of their work and called me to pick up my van. I asked them again if it leaks, "oh no, we ran water over it for hours, it's bone dry" -they answered. So I went home and...I just had that urge to take a peek...so I removed the chairs and lifted the rug...it was soaked. Drove back and showed it to them, they were surprised? so I left the van there AGAIN. After a couple of days picked it up and again they said was day. By now, I am an expert in the detail field of auto mechanics!!!, so I removed the trim by the slide door driver side, lifted carpet and put my hand in there, yes you read my mind...it was really wet.
At this point, they said they are going to take my van to a water leak specialist, now that's an advancement in the rational thinking in this irrational world, I mean, I've only been farting around with this leak problem for 2 stinking years , and just now you just came to that conclusion? Brilliant!
Anyway, after I got my van back, I saw some metal shavings in the back, offcourse no one knew where they came from, it looked like someone drilled something.
So I went home, and peeked again, well, me and my beloved wife spent our Forth of July, removing the carpet all the way up to the driver seat, on our knees scrubing the entire van floor from the mold that already had grown. In addition to that, I found holes drilled in the body of the van, right under the hatch bottom molding, and voila! The water would came into the frame (there are a couple wide hole openings and inside there, I could see holes drilled, I could see light from outside. I was not a fortunate owner of a 12 gauge, but I whished someone had remembered me in the last Christmas! (no I would not use it on the van or the wife...)
So the dealer was surprise again to see holes in the van. Their theory, "we don't really know where the water comes from, but we sure know how to get it out..."
Ok, I admit that there is no water coming inside the cabin area now, so the carpet remains dry, BUT now it seems to pool in the hatch door from outside. So after it rains, and I open the hatch, water comes gushing out of the handle from outside, and that is where I am at. Don't really know how it gets there. Hopefully that does not cause a problem in winter in the freezing temperatures, we'll see...
So the dealer wanted to give us "new horses" at the tune of $23,000.00 for a brand new 2010 Toyota Sienna (actually I think is their cost), an idealistic perfect solution for a water leak, right? No, my wallet got constipated...so the the genius had ANOTHER solution, a bumper-to-bumper premium warranty for our "holly bucket" for 2 years or 24,000 miles...I took that because they did not have another van to trade-in with, and that is all folks!
If you wondering about all this "comedy" written in this post, is because, if I ain't laughing...I'd be crying for a loooong time. Maybe I should write a book about this a nd sell it on the internet, and make millions!

Hi all -- I've got a 2000 Sienna, bought used 1 year ago, and have similar problems as everybody else on this forum. What a nightmare! I have at long last found a temporary solution -- not satisfactory in the big picture sense, but in the short run anyway, it seems to help. Fortuitously (by design ??!?) there are removable plugs, about the size of a quarter, directly underneath (on the bottom of the frame, as in, lay on the ground to find these) the driver's seat and the passenger seat. There is a slightly smaller one at the back. underneath the rear hatch (again, UNDERNEATH on the frame) under the rear hatch, driver's side. I removed these 3, and so far this fall/winter, no new water has accumulated beneath my feet in the driver's compartment. Like I said, not an IDEAL solution, because it does not actually solve the root problem, but at least my feet aren't sitting in a wading pool ......
#48 of 128 Sienna 2002 water leaks
Oct 28, 2009 (6:22 am)
Our leak showed up after we'd owned our used 2002 sienna about year and a half last month. I soaked it with shampoo/lysol, then vacuumed , dried blowed, etc. No luck , especially since we've been having soggy weather. My independent mechanic took a day & half to figure it out, partly thanks to you. Keep your fingers in the dike, thanks.
