#80 of 128 Re: Waterleak in the storage area [jmbuddies]
Mar 21, 2012 (8:12 pm)
Check the bottom of your cargo area or front driver/passenger side, esp. after lots of rain if you have a 2011 Sienna van. We have an SE model. After a few consecutive downpours this past month - 3 days of pouring rain, I went to get the stroller out of the trunk. I noticed a few light large spots at the bottom of the rear cargo area. I put my hand down and noticed the area was wet. Strange because we don't store liquids in the back. I told my husband and he checked it out. Turns out the entire trunk/cargo area was soaking wet...right down through the padding underneath the carpet. It took 2-3 entire large paper towel rolls just to barely get the puddles under control and airing out the back. Luckily it was sunny for two days after we discovered the issue. The van started to stink from the mold forming ,and we were panicking since we have kids with allergy and asthma. Mold alert. The metal underneath the carpet padding had started to rust a bit. We just bought the car back in August of 2011. Took the car back to the dealer service center. First diagnosis, they called us next day and told us it would be $1290 because it was our fault one of the back windows latch was not sealed closed. Funny because we didn't even know we had back window latches and even when the service person in charge did a walkabout, no one noticed the window open. Ironic that nothing else was wet too from the top down. Not the back seats, not the strollers and kids knicknacks lying on top of the cargo area. So it's our word against theirs. I asked him if he was absolutely sure. If they had checked out all other posibilities and tested other possible entry points. He said that they were Toyota trained specialists and they were 100% sure. I'd read on some posts that after a few times of the same thing happening to another individual, they finally called in Toyota engineers to come look at it. I asked my service guy if they could do that and again, "ma'am, we ARE the factory trained technicians." After deliberating with my husband, we felt we had no choice but to have whatever needed done to fix the propblem properly to be covered under the warranty. Especially since we have one car and our kids are physically sensitive. After we gave them the go ahead, they were finally able to open up the mess (so before, it was just their best "guess" as to how the water had gotten in. They need our "okay" for the charge to actually open up the car). They tested the back and said it was water tight. Then they asked me if we parked on an incline. We do. About a 30 degree incline tops. Found out the water was actually coming in the through underneath the windshield "gutters" into a channel alongside the sides of the inner frame and flowing back to the cargo area. So guess what, we are covered under warranty. This is the kicker though, service person mentioned that yes, the water leaking in was probably happening for the lifetime of the car. He even told me that there was another same Sienna 2011 that had come in with the SAME issue. It is a design flaw/defect. So how do you fix that? NOW they are bringing the actual factory Toyota guys who will look over the repairs. Someone wrote on this board that they had just drilled holes underneath the car so the water could escape and not reach the back. I DON'T want holes drilled into my new car. And that person still had even worse water leak issues. Have been trying to find out if Toyota will in the least extend my warranty or do something about this car we just bought with a defect built into it. So, if you have a Toyota Sienna 2011 SE, have it tested. It's been two weeks since they've been "holding" our car. Said they are waiting for parts and are waiting for the Toyota factory guys to come oversee this repair. Wondering with the big recalls they have now if they are keeping this under wraps or if people are still unaware of the defect unless they parked like us on incline. I've read various posts where the 2011 Sienna leaked in the front driver and passenger areas which is worse because of the electronics and wiring. I am very concerned the problem will come back after reading some other posts on the web. Toyota has to do something for all of us who have just purchased new vehicles in good faith.
#81 of 128 I got my leaking sunroof problem permanently fixed for free.
Mar 22, 2012 (1:59 pm)
The sunroof on my 1999 Sienna kept having leaking problems starting in 2009/2010. I got real tired of cleaning up puddles in the front seats etc.
I had to take my van in for some significant maintenance and repairs this past Fall, (to the tune of over $2,000). The one mechanic had made some major mistakes, (like when he said that I could pick up my van, while they were waiting for a new catalytic converter to come in). But when I picked it up after hours, after turning my rental car in for the weekend, there was no converter in it!! Idiot!! Anyway, in an attempt redeem himself a tiny bit, he said that instead of putting in a new sunroof, which would cost a lot, he could permanently seal it up for free. (Normally $25.00). Since I very rarely opened the thing up, I agreed to that fix. It's really nice not to have to worry about car washes or rain anymore!(Especially with the torrential downpours and hail that we had recently in San Diego!) Patty T.

My 2010 Toyota Sienna Limited is having theexact same issues. No one is quite sure why because Toyota has no records of other people having these issues. It makes me so upset that they do not stand behind their products. Poor quality and ever worse customer service in my opinion.

#85 of 128 Water leaks and floor seals recall issue on 2008 Sienna
May 03, 2011 (12:52 pm)
I've tried to find an answer to this - but I'm either coming up with mystery leaks or references to a 2011 recall, nothing concrete.
I am seriously about to lose my flipping mind over my van.
I'll try to make a long story short. Last summer I had the van open in the driveway to vacuum it out. My son was aiming a squirt gun at the back of the van - door open. I noticed water in the back - where the 3rd row folds into - and I asked him what he was thinking and made him put the squirt gun away. A few days pass and it isn't drying out. And it smells. I decide the water must be leaking in from rain, and my son had nothing to do with it. Take it to the dealer and they say that there are leaves and stuff in the crack/seal of the rear lift gate and that is the problem. It doesn't seem very plausible to me but I don't really have a lot to argue against here. Clean that out, figure that's it, but the smell remains. I try lysol, alcohol, sun - can't get the smell away. My solution is to keep the third row down so at least I can't smell it.
Just had a baby a few weeks ago and now we need to use the rear row. Opened it up and it is VERY wet underneath and smells like an open grave. I go to an independant mechanic and say find the leak - they find it but say since the car is so new, I should go to the dealer. Back to the dealer - this time they find the leak and say it has something to do with a floor seal recall and MAYBE that spare tire recall? The paper work says "floor seals replaced during open recall." Is this the spare tire recall??? I asked if they would cover getting the mildew taken care of since this was a recall issue. They told me to call main Toyota - after some back and forth the dealer agreed to clean it. When I went to go pick it up they were making vague references to "You must have left a window open."
It still stinks. I am now trying to get the dealer to replace the carpet. The customer relations lady is saying this has nothing to do with the recall, this is not our fault, we did everything we can. I told her I had paperwork stating floor seals were replaced and the leak should now be fixed. She was like, OH. Can you fax that over to me?
All I know is, the water was coming from UNDERNEATH my car. All winter. I did NOT leave a window open (under my car?). The car smells so bad that anything left in it for any length of time needs to be washed. I can't leave my stroller in the back or it stinks - even being in there a few hours, it will smell a little. There's no way I could take this car anywhere like on a road trip where things would have to be left in the van overnight. I don't even feel like it's safe to be driving my kids in this van.
Has anyone else had this problem? What exactly is the floor seal recall? And does it pertain to the 2008? Because I am just waiting for their response to be, this paper work doesn't matter, the recall doesn't pertain to your vehicle, this is a mistake.
Worst case scenerio I guess we pay out of pocket to replace the carpet but I don't feel like we should have to do this when the van was leaking from underneath due to no fault of ours.

I was reading thru a recall notice, and happened to remember the question you posted last month. The floor seal kit is P/N 04000-41145, and is part of the spare tire winch recall. But it is not what you think - it is a set of sponge rubber blocks that help to reduce the amount of salty water that make it up onto the spare tire assembly under the vehicle. It's purpose is to reduce rust to the carrier that sits under the middle seats.

Hey - thank you for answering! This is actually bad news for me as that means I STILL don't know why my car is leaking. So a week after faxing the paper work showing "floor seals replaced during open recall. This should correct water intrusion" as well as the paper work saying I had the van in last summer for a leak and they couldn't find one I got a phone call and the lady said it was not their fault, they can't replace the carpet, I had to call Toyota. Five minutes later they called back and said they would replace the carpet. NO idea why. So the carpet has been replaced. I asked that they be sure the leak is fixed while the carpet was out - and my van no longer smells - but now I wonder what if it WAS another issue? I know for sure the water was coming from underneath. I did not leave a window open. It seems to be OK now but I don't have the 3rd row folded down so any moisture would dry faster if anything was coming in.
So at this point ... I don't know what to do. Maybe I should take it to another dealer and have it tested for leaks???
The lady at my dealership did say these seals have nothing to do with water leaking in but that was NOT what the service people told me. Hence my confusion. I really don't want a mildewy car again - it was SO gross!!!
Maybe I should sell it while it smells good and be rid of it? LOL Only problem is we have an 8 seater and I HATE the redesign of the 8 seater so I would want a used one... which could put me right back where I am.

Glad I could help (a little bit...). I understand your frustration. Leaks can drive you crazy, and can be so difficult to trace.
There are a few plastic plugs in the underbody that lead into the seat well area and into the rear quarter panels. If you look at some of the hitch instructions, they show places where you can route the wiring in from outside. I'd start by making sure they are intact.
Next, when it rains, open up the jack door (right side) and make sure that area is dry. It could be a roof leak that finds it's way down thru the "C" or "D" pillar and into the lower body structure. It is possible to remove the large plastic interior piece on the left side to check that side as well.
You will also find the rear AC unit is in the right wall, and there is a condensation drain hose that runs by the jack holder that could be disconnected or leaking.
Any of these could back up water into the interior.

Thank you so much! I will look into those areas. I am inclined to think the AC is not involved because of how this got so much worse over the winter when I was not using the AC but who knows. Those things sound easy enough to look into. I am also going to take it to another Toyota dealer and have them give it a once over just for reassurance. And in the back of my head I still think "sell the car and run!!!!!!" Trying to come up with some answers to this problem it just seems I came up with stories of SO many mystery water leaks in the Sienna. Coming from the spare tire issue which covered such a LONG period of time, it seemed logical to blame that, but maybe, maybe not. I absolutely love the design of this van vs. the captain's chair models (I like how all 3 middle seats are really reasonable seats and can hold a car seat) but I don't like this mystery leak issue.
