If you have a sunroof the drain tubes being clogged will do this. My drivers-side tube clogged, and the floor is soaked. No visible signs of water entry, but a can of compressed air showed clogged. The outlet generally clogs with dirt. You can fish a thin wire down it or find the drain under the car. Bake cable from a bike works well, but be sure the wire is not sharp. The drain tube is thin wall rubber stuff. Use soapy water as a lube. Some use compressed air to blow it out, but this can rupture the "thin" tubing.
 
The rear door seal leaking can cause it too. The rear padding and carpet would be wet too though.

#76 of 122 Radiator/Transmission Leak by owego

Sep 04, 2011 (8:25 am)

I have 2006 Sienna with100K miles. A fitting in the radiator has come loose. It's a screw-in bolt in the lower left hand side of the radiator, just above the radiator hose. It's got a "O" ring at it's tip and a hose fitting to the transmission. I'm afraid the female threads in the radiator body must have stripped out, because there is no way the bolt could have just come loose, the hose fitting on it's external would have prevented its turning.
 
I've tried to screw it back into the radiator, but it just won't catch.
 
The van is undrivable now due to "open" in the transmission fluid line.
 
Any suggestions ?

There are two main places it leaks from... One, is the rubber window seals in the rear, where the pop-out windows are.. they don't seem to seal correctly, and water runs around the channel and into the van behind the plastic interior. Another place is from the rear door, it seems that water leaks into the van through the door, as the van is raked forward it causes water to sit in a crappy place and causes the floors to get wet.
 
To those having the stale smell, this is nothing new either, My solution was to use fabreze, spray it into the intake vent on the outside of the van before replacing the cabin filter.. It seems to cause the filter to get black with crud... once you run it through the vents for a few minutes replace the cabin filter and you should notice not only the smell gone, but the vents should run better.. I guess after 10 years dust just builds in the vents..

i am having the same problem with my 1998 sienna. i removed the carpeting and today while it was raining i noticed the trail of water snaking from the rear to the front. these model years definitively have a problem with leaks from the rear hatch. i am going to try and replace the rear door seals and see if it works

#79 of 122 Toyota Sienna 2011 water leak in storage cargo trunk area by ipresumed

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. Anyone else have similar issues?

#81 of 122 I got my leaking sunroof problem permanently fixed for free. by 99siennaowner

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.

RUN as fast as you can from a TOYOTA! Especially a Sienna.
