The contact owns a 2025 Toyota Sienna. The contact received notification of NHTSA Campaign Number: 25V668000 (SEATS). However, the part to do the recall repair was not yet available. The local dealer was contacted. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was made aware of the issue and informed the contact not to use the second-row seats. The contact stated that due to the recall, the car seat for the newborn had to be placed on the rear seat. The contact believed that the temporary solution offered by the manufacturer was not suitable, since the contact also owns a big dog. The dealer stated that a rental vehicle would be provided once the remedy was available. The contact had not experienced a failure.

My vehicle is subject to an active safety recall involving the second-row seat rail welds. According to the manufacturer’s official recall notice, the remedy is not yet available and there are current usage restrictions advising that no occupants should sit in the second-row seats and that no child restraints should be used in those seats until the repair is completed. This condition creates a safety risk because the second-row seating positions cannot be safely used, which limits passenger seating and prevents proper use of child safety seats. The manufacturer has confirmed that the recall remains in interim status and that no repair or alternative remedy is currently available. The issue has been confirmed by the manufacturer through an official safety recall. No warning lamps or messages appeared prior to this issue, as it was identified through the recall process rather than a vehicle malfunction during operation.

There is a recall from October 5 2025 regarding second row seats that are mounted on seat rails that may have been improperly welded. They recommend not to have anyone sit in that row or use child restraints. How is there no remedy at this time?? Who can have their passengers sit in the third row and avoid sitting at the second row. This is negligence from Toyota and should have a remedy right away. We bought this car in March 2025 and have been driving our two boys around for several months until being notified of this recall! How can you expect someone not to use the second row seats for months without an answer particularly a minivan.

Driver side mirror causes driver to be nauseous and eyesight to be distorted

The contact owns a 2025 Toyota Sienna. The contact stated while driving 65 MPH, the sunroof glass shattered. There was no warning light illuminated. The local dealer was contacted; however, the vehicle was not diagnosed or repaired. The contact was informed that the VIN was not under recall. The manufacturer was not notified of the failure. The approximate failure mileage was 275.

Wobbling vibration on exterior mirror, driver side. It looks like incoming vehicles shake sideways. This happens on any bumpy road and it is easier to observe at highway speeds. Also, every time I close the door, mirror shakes as it its loosely attached. Driverside mirror has too much play and shakes. There is no issue with play and shakes with passenger side mirror. Purchased on [XXX] Vehicle is available for inspection. The distorted image resulting from mirror wobbling affects driver's awareness of surroundings, visibility gets worse at nights/rain due to blurred lights. This can lead to an accident. My intuition when I first noticed was going to be a cold break, but I realized that it was the mirror wobbling causing it. The car coming behind was far enough and I was able to react. Summary of actions and requests to Toyota: I went to my dealership Crestmont Toyota, Pompton Plains, NJ and they have confirmed the play and wobble issue, however, they said it's the same thing with other 3 Sienna's they had on LOT. Dealership informed that this is how its manufactured and they can't do anything until TOYOTA issues a recall for this problem. First occurrence: Day one, driving back from the dealership.

Driver side wing mirror vibrates at low speeds and worsens at highway speeds greatly affecting rear visibility. Passenger side has no vibration but drivers side is so severe it's difficult to make out anything in the mirror image.

Driver side mirror is loose and is vibrating even at normal/slow speeds

The drivers side mirror vibrates causing distortion that makes it difficult to judge distances on highways. This issue seems to be a structural defect in the door not the mirror. Multiple people are complaining about this. Many have had the mirror replaced only to still experience the issue myself included. I have test drove two brand new 2025 Sienna and the issue was present there as well. It is very much a safety issue.

After very minor rainfall, my rear backup camera was not usable as water was dripping off of the edge of the door handle trim and it was getting on the lens. This is a complete design problem as there should be a drip edge. You made it very difficult to properly pull up at a gas station pump and I was unable to get close to the pump because of how the lens was obscured by the water drops.

Outer rear-view mirror on the driver side exhibits a vibration/shaking of the image. It is obvious and continuous vibration is observed typically on highway speeds of approximately 60mph or higher and lower speeds it is evident driving over slight bumps, concrete/asphalt road surfaces or bridges. Looking at the shaking image cause dizziness and it is even worse in night time with headlights from vehicles coming behind. It is annoyance to the point that makes you feel not to use the rear-view which can potentially put the vehicle and others in danger. Passenger side doesn't vibrate and makes it easy to notice the issue. Dealer inspected the mirror and said manufacturing issue and replaced it under warranty with no success is fixing underlying vibration issue. On the second visit, dealer denies the problem and says the mirror is replaced and operates according to toyota specification (it feels to us they do not care about the functionality). According to dealer they will do anything further only if Toyota release a TSB on this particular issue.

The drivers side exterior mirror shakes. This occurs during all driving, most notably over bumpy roads and at highway speeds. The passenger side mirror does not have this problem. Because of the shaking, it is distracting when driving as it appears there is movement in the mirror. Additionally, it causes a distortion from the constant movement. The vehicle was purchased in June 2025 and has occurred since day 1. The vehicle was in the dealer on 9/30/25 and noted the issue, stating there is nothing physically wrong with the mirror but did agree with the assessment. They said this is common on vehicles (they see the complaint a lot) but Toyota has not acknowledged it so there is no fix and appears to be a manufacturing defect.

The driver side mirror vibrates at highway speed enough as to make it useless to observe cars behind you. Moving the mirror around does not help.

The sunroof leaks. Took vehicle to dealership. Was told they saw drops of water around the light housing. This could cause an electrical malfunction which could be a safety hazard. They could not find the source of the leak. There are other 2025 Sienna owners talking about their sunroofs also leaking. Thank you.

Trunk hatch knocked out of alignment. The dealership said it is because the door was closed when something was in the way. If there was really something in the way it should've been picked up by the sensors.

Moonroof on my new 2025 toyota sienna has water leaking in. I've brought it to the dealership to try to resolve this. They said they fixed it. But I've just got a carwash and I still water leaking in. I have video of this. It shouldn't leak or be design to leak like the dealer said.

I bought this vehicle brand new. I quickly realized that both rollers on the sliding doors were causing excessive noise, which I found out that many other owners have complained as well, when closing & opening. This is because of a poor assembly from Toyota as the rollers are not machined prefect painted & are either oversprayed or less sprayed causing gaps on the rollers. These gaps or uneven paints causes excessive noise when rollers are moved on their track. There are several new Sienna owners who are waiting to have this issue fixed as the parts are backordered. I had to make total of 4 trips to my local dealership to have the issue fixed. I can still hear a little bit of over excessive noise from one of the sliding doors. Toyota should immediately recall all the affected vehicle and have this issue fixed.

Driving roughly 60 mph on empty road with no cars in front. Sunroof was closed, and exploded with great force and 80% of the glass flew off. No objects impacted the sunroof prior to the sunroof exploding.

UNKNOWN Dear Toyota Motor Sales, U.S.A., Inc. Consumer Affairs Department: I am writing to formally demand a full buyback and refund for the above-referenced 2025 Toyota Sienna (the "Vehicle") under the Arkansas New Motor Vehicle Quality Assurance Act (the "Arkansas Lemon Law"), Ark. Code Ann. §§ 4-90-401 et seq. The Vehicle is subject to a critical safety recall (25TA12, with interim notice 25TB12) involving improperly welded second-row seat rails, which poses a substantial risk to the safety of myself, my passengers, and others on the road. As of the date of this letter, Toyota has issued no remedy for this defect and provided no estimated timeframe for when a repair will become available. This renders the Vehicle unusable for its intended business purpose and out of service indefinitely, in violation of the implied warranties of merchantability and fitness for a particular purpose, as well as the express warranties provided with the Vehicle. Background and Defect: I purchased the vehicle on [XXX], new from Landers Toyota NWA, Rogers AR for $49,058. The Vehicle has been registered and primarily used in Arkansas since acquisition. On or about October 7, 2025, Toyota issued Recall 25TA12, notifying owners that the second-row seats in certain 2025 Sienna models, including my VIN , are mounted on seat rails that may have been improperly welded. This defect could cause the seats to detach during a crash, increasing the risk of injury or death. An interim notice (25TB12) followed, confirming the issue but explicitly stating that no repair remedy is currently available and no loaner vehicles or temporary fixes are being provided. Since receiving notice of the recall, the Vehicle has been effectively out of service for safe operation. I cannot, in good conscience, use this vehicle with a known safety defect that compromises occupant protection in the event of an accident. Toyota has failed to provide any repair, temporary solution, or estimated completion date, leaving me without a functional vehicle for commercial purposes. As of today, the Vehicle has been out of service for approximately 21 days due to this unresolved nonconformity, and with no remedy in sight, it will soon exceed the 30-day threshold under Arkansas law. Violation of Arkansas Lemon Law: Under the Arkansas Lemon Law, a "nonconformity" includes any defect that substantially impairs the use, value, or safety of the Vehicle (Ark. Code Ann. § 4-90-403(6)). The seat rail defect clearly meets this definition, as it directly endangers passenger safety and renders the Vehicle unfit for ordinary use. Ark. Code Ann. § 4-90-410(a) establishes a rebuttable presumption that Toyota has had a reasonable number of attempts to repair the nonconformity—and thus must provide a refund or replacement—under the following conditions, among others: (2) The vehicle is out of service by reason of repair, or attempt to repair, any nonconformity for a cumulative total of thirty (30) calendar days. In this case, no repair is possible because Toyota has not developed or authorized a remedy. However, the Vehicle is undeniably "out of service" due to the inability to address this safety-critical defect, and the indefinite delay ensures it will remain so well beyond 30 calendar days. Courts interpreting similar lemon laws have held that irremediable safety recalls qualify vehicles as "out of service" from the date the owner is notified, as the owner reasonably withholds use until the hazard is resolved (see, e.g., analogous interpretations under federal Magnuson-Moss Warranty Act, 15 U.S.C. § 2301 et seq., which supplements state lemon laws). Toyota's failure to provide a repair within a reasonable time triggers the presumption of a "lemon" under § 4-90-410(a)(2), entitling me to the remedies outlined in Ark. Code Ann. § 4-90-412. Additionally, pursuant to Ark. Code Ann. § 4-90-405, INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

We were notified by Toyota that the second row seat rails had incomplete welds. Toyota recommended no one ride in the second row, and no child car seats should be installed in the second row. This greatly impacts the use and safety of the vehicle for our family of five. Additionally, the value of the vehicle has been impacted. Dealerships are not willing to give fair value for a trade-in because they know the vehicle will sit on their lot for an unknown amount of time before the repair is available. At this time (now 60+ days since the recall was announced), Toyota has not released the remedy and there is no timeline for the completion of these repairs.

See recall above. We just spent $55,000 on this vehicle in order to safely transport and travel with our two year old and newborn. The fact that Toyota does not have a remedy available for this major issue is completely unacceptable. The recall notice states that our only current "remedy" is to not use the second row seats, which is not feasible since child safety seats only safely install in the second row. This so called "remedy" is absolutely unreasonable, illogical and irrational. It essentially renders our $55,000 vehicle unusable, which constitutes a significant financial loss for my family. I am making a loss of use claim - Toyota's response that it does not have a remedy available now for such a significant safety problem is outrageous.

The blind spot warning only shows the flashing light in the side mirror but does not make an audible warning sound.

When i am driving from high speed and trying to use my brakes, the whole rear car will start shaking around 48/45 miles per hour , I can hear our car seat from our baby how it makes vibrating noises and i can see my both door mirrors they're shaking too, and when it drops to 40mil per hour the shaking goes away. Went to the local Toyota dealer 3 times and they're saying that's normal. Very disappointed with a brand new car. We have another new car and doesn't do that for sure... Called Toyota national, open a case and they're saying, mechanic can't find anything wrong. They should drive this car for a longer distance and they will know for sure what I am talking about.

Driver side passenger 2 nd row seat belt stopped working. Won't clip as needed leaving us unable to use seat. This is a safety issue as we are not able to use the seat as needed as one is not able to strap in. This triggers the sensor and this a driving violation. Problem has been reported. Vehicle has been reported and still pending to be replaced. Unkown when issue can be resolved. Passenger seat on the second row was stuck upon purchase. Dealer made aware. they claimed a sock was stuck on railing which was not possible as issue was reported before they could schedule for vehicle to be inspected. Such sock did not exist when incident was reported. Sock was not purchased until day before taking vehicle to schedule appointment. Tension is still there but agency said it is working properly.

I bought this van brand new. I quickly realized that the reverse camera view has some issues. I believe images are not clean and sharp, as it is supposed to, and has unreasonable amount of distortions. Cleaning the camera from outside didn't do anything. I also noticed that the bottom part of center blue alignment line is little bit to the right and not align with the top. I checked online and it appears that other owners are also suffering from this same issue. Toyota should recall all affected vehicle and fixed this issue as soon as possible as this is a major safety issue when backing up!

Purchased a **2025 Sienna XSE** with severe alignment issues since new. After **two failed repair attempts** at Fort Bend Toyota, the steering is now worse, and they damaged my wheel without offering solutions. This is a **safety hazard**—the car drifts dangerously at slow and highway speeds. The dealership dismissed my concerns, forcing me to escalate to **NHTSA** and **Toyota Corporate**. Avoid for serious mechanical issues—safety clearly isn’t their priority.

The drivers mirror shakes every bump you hit so everything looks blury going above 30mph. This is a huge safety concern as you can't see cars clearly in the mirror. One of the second row seats also shakes considerably. I have brought it to the dealer multiple times and they will not fix it.

Drivers and passengers front doors make the sound as if they unlock and lock. The manual lock lever will flip as well however the doors will not unlock. This happens randomly both while trying to exit the vehicle and enter. When locked inside you have to crawl over the console to get to a door that functions . This is a major concern if you are in an accident and cannot exit the vehicle. Dealer look at my vehicle but could not duplicate it. I have a video of this when it happens
