Toyota Sienna Water Leaks

Comments

  • 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.
  • 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 ?
  • Update to say after the carpet was replaced it started leaking again. Called another dealer who referred us to a guy called the water doctor. He found the seal around the back was leaking at the bottom - very common - how did they miss this??? sealed that up and gave a one year guarantee. Month later, water again, starting to smell - he came back, carpet was SOAKED, found one of the plastic plugs (grommets) in the underside of the well area was either poorly sealed or never sealed. This is where the whole leak originated - HOW did the dealership miss this??? So over a year later, having been without my car on something like 5 occasions, having carpet replaced, having the dealership TWICE indicate the leak was in some way my fault - I am back at square one, with mildewed smelly carpet. But I THINK the leak is finally fixed. Now I am trying to decide whether or not it is worth the time and effort to even let the dealership know how big a boo boo they made and why they have lost us as customers. We are just one family but we are a two toyota family. ;-)

    What a mess!!!
  • Hi:

    My husband and I purchased a certified 2008 Toyota Sienna XLE AWD in April 2011. About two weeks ago we noticed that under the third row seat the rug was wet. We contacted Toyota directly and was given a claim number and a case manager. The case manager instructed us to bring the car back to the dealer. The dealer couldn't find a leak so they hired another company that specializes in leaky cars. Today they found the leak. The water was coming from under the car in two areas and also through the 3rd backup light area. They are washing the rug but we did request a new rug. Waiting to see what happens. When we brought the car in for water problem we mentioned about the recall and they said that since this was an XLE it wasn't included in the recall because we don't have a spare tire well. This just show how wrong they can be.
  • Wow corporate Toyota never even gave me a case manager. They gave me a claim number and then I never heard anything until I called them back 2 weeks later - and they just told me to call the dealer. Unhappy Toyota owner!!!
  • Try getting a case manager assigned to you. Our case manager calls me every week to see how things are going. I forgot to mention that the reason we don't have a spare wheel well is because we have the no flat tire on the car.
  • I am not even sure what I would be pushing for at this point. I'm out over $200 trying to get answers, for something that should have been corrected under warranty - it seems like small potatoes, and yet... it's still $200 I shouldn't have had to spend, you know? Plus all the aggrivation and time with out a car etc.

    I think you misunderstood some of what the dealership said to you. Because you have an AWD van, you don't have a spare tire. There was a recall for a cabling system & hoist corrosion problem that some thought was related to how water might get into the interior. That hoist apparatus mounts under the right hand second row seat - but only on FWD models.

    Who do you think misunderstands? Me (the original poster) or the guy who just said he has AWD? My van is not AWD, I have a spare tire. I have paper work stating the faulty floor seals caused the leak - they fixed the floor seals, they replaced the carpet, the leak continued.

    In the end the leak was so obvious I don't know how they missed it. I feel stupid because I didn't check but I had no idea how to even get the carpet out and I am not a mechanic so at least I have that to go on. :-)

    (editing to say clearly the floor seal issue did not cause the leak, so the paper work is wrong, but I have it! the dealership actually claimed this, this is not a misunderstanding on my part)

    Reread my post. It clearly says "Replying to: Brandybrindy"

    and they said that since this was an XLE it wasn't included in the recall because we don't have a spare tire well. This just show how wrong they can be.

    Unless you changed your name, you are yelling at the wrong guy. You might look back a few posts and remember that I provided you with a lot of information early on. I'm once again trying to help someone else out who doesn't thoroughly understand the situation, or what they are being told.
  • I'm not yelling, really. :-) Just confused. I apologize.
  • fibber2fibber2 Mid Hudson Valley, NYPosts: 3,732
    Accepted! Sorry to hear that you are still having difficulties with the van.
  • 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
  • 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?

  • 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.

    Updating this to say that after many attempts to fix the leak, we took a loss and traded the van in- supposedly to go to auction. Have come to find the dealer sold it as "certified" but without fixing the leak. I have this in writing from the dealer - it's not mere speculation. Actually told me there never was a leak! We had cases open with corporate over this leak. Van was definitely leaking. Should someone who bought a used 2008 Sienna near Pittsburgh PA on August 24th, 2012 come to find it is leaking and want the details - let me know. Not sure how to find them otherwise but on the off chance they find the leak and google leaky Sienna... maybe they will find me. Cannot believe the audacity of car dealerships.

    Probably the best design ever for a family minivan - hate the new Siennas, Odyssey is a lukewarm runner up.
  • 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.
