What owners say
Leaking water into passenger side during rain. Many have reported the same issue. Seems to be some loose seals on the roof.
Water leaks to the driver and passenger floor when it rains, it seems a leak is coming from the windshield area, touching the car hood
For about 3 weeks my spouse noticed a musty smell inside the van and then noticed that the entire cabin carpet was soaking wet. On 09/14/18, I took the van to team toyota in glen mills, pa and had the AC lines drained. The carpet was still getting wet after having this service done. On 10/09/18, I took our van back to team toyota to have a company called the "water doctor" to diagnose the water leak problem. Team toyota advised that the "water doctor" discovered the leak was coming from below the front windshield cowl. The "water doctor" applied a sealant to the effected area. Team toyota replaced the padding and deodorized the cabin area. My bill to have this repaired was $551.20.
Water leaks into driver side widows pillar on to side curtain air bags as well as left rear second and third row seat and third seat air bags curtains.
The headlight bulb compartment allows water to leak into it on the passenger side causing the bulb to blow. This has happened twice, the repair cost was $500. We drove the car for one week and the bulb blew again because water leaked into the compartment. This is a design flaw and is hazardous when you are driving at night or god forbid if it's raining and dark. We also were pulled over and given a warning from a state trooper about the bulb being out. This is a dangerous and costly situation. We are still waiting to get the bulb repaired a second time. In the meantime we are without a van for our family. Please demand that toyota recalls this hazardous defective part. The bulb went out while we were driving at night. This is a problem and a hazard!
Bad water leak when it rains can't figure origin ending up with lots of puddled water in rear storage section. Causing soured mold smell two of my children have asthma not a good scenario or combination. I would not consider sending this, but there are many reports this type of issue with nothing being done to rectify problem without customer being financially responsible. I also understand that not everyone has asthma, however; black mold can be a hazard for all. Just wondering what can be done. Should be some sort of recall in place...*first started for us mid march 2017. In research I have found that many others have had this issue with no resolve.
Tl* the contact owns a 2002 toyota sienna. The contact stated the vehicle leaked water from the air conditioning system and the SRS air bag warning light illuminated. The vehicle was not diagnosed or repaired. The manufacturer was notified of the failure. The approximate failure mileage was 24,000. ...updated 09/12/16 *bf the consumer stated the vehicle was repaired under an extended warranty.
I have brought the sienna into toyota on 3 separate occasions, as it was clunking when it closed. I was told there was nothing wrong with it each time, but the liftgate was clearly not aligned. Water is now coming through the top of the lift gate. I did back up into a tree, and had damage to the back quarter panel and it was repaired by a body shop. Toyota is stating that this caused the liftgate to be misaligned and that is causing the water to come through the liftgate. However, it was not until I ran the minivan through a touch free carwash and water was applied under pressure that I noticed the water coming in. My complaint is I believe that if the liftgate could be misaligned by quarter panel damage, what would happen under extreme stress of a car accident. I do believe the dealership is avoiding realigning the lift gate, but I am also concerned about the overall safety of the vehicle in the event of an accident. Also, the original tires that came on the vehicle wore very early. I replaced all 4 tires at toyota because we were taking the vehicle on a family trip. I was looking through the owners manual and noticed that the original tires were to have a 6 year warranty.
The air conditioner housing is leaking water onto safety-critical parts. This housing is made of plastic parts that are glued together. Water is condensed during the cooling cycle, and it then collects at the bottom and exits the vehicle through a rubber hose. The glue holding the housing together has failed. Water is leaking from the housing and running onto the computer module that deploys the airbags. I have been advised by the dealer that it is not safe to drive the vehicle with a wet module because the airbags can deploy while moving, or that they might not deploy in the event of a collision. An identical problem affects toyota models camry, avalon, and venza. This recall can be found at: www.toyotanews.pressroom.toyota.com the recall info is: releases/toyota/recall+camry+avalon+venzaoct17 this will turn into a serious safety issue as these vehicles get older water can leak onto the deployment module without being seen. In my particular case, the water had apparently been leaking for some time - perhaps a year or two - and was detected purely by chance. There was significant rust on the floorboard of the vehicle. I have discussed the issue with toyota, and they refuse to do anything about it. The circumstances of the recall on camry, avalon, and venza appear to be identical to the circumstances I have experienced, yet there is no recall on the sienna. This appears to be an unsafe condition. I would appreciate it if you will take a look.

Recall number 10V160000 · Recall details
Structure: body: hatchback/liftgate
- What is wrong
- Toyota is conducting a safety improvement campaign involving 196,222 my 2004-2006 toyota sienna vehicles equipped with power rear liftgate struts. The gas struts used to help lift and support the rear power liftgate could wear out sooner than expected. As the gas struts deteriorate, the performance of the liftgate will begin to degrade and the power rear liftgate will operate more slowly than when the gas struts were new.
- Risk
- If not repaired, the gas struts may not be able to support the weight of the liftgate when it is open eventually, the gas struts could deteriorate to the point that the liftgate will fall about ten inches after it reaches the fully open position, at which point the power motor will engage and power the liftgate to the fully closed position. This condition may cause injury to a person who is struck by the liftgate when it falls or when it is closing.
- Remedy
- Dealers will replace the gas struts with newly designed gas struts that have a longer service life. The campaign began on august 8, 2008, and will be mailed in three phases ending in late december 2008. Owners may contact toyota at 1‑888‑270‑9371.
