SEATS, FORWARD COLLISION AVOIDANCE: WARNINGS
"We were notified by Toyota that it was unsafe to transport our children in the second row seats in November 2025 and the vehicle was under a recall. This puts our children at risk. A letter from NHTSA stated Toyota would have a remedy by 12/6. The manufacturer (Toyota) confirmed this recall. Given that Toyota has not indicated a solution date for this and the problem was discovered in October 2025 I believe the manufacturer has failed or is unable to remedy this safety recall for our vehicle in a timely manner and would like to officially log a complaint with NHTSA.

The manufacturer had exceeded a reasonable amount of time for the recall remedy. They have declined my requests for them to set expectations for a number of months or years after which a remedy will be available.

We bought a new Toyota Sienna 2025 in April for our growing family of 5. On 10/7/2025 a recall was released stating to not use our 2nd row seats due to the seats being improperly welded to the frame. We use three car seats. We have since been placed in three different rental vehicles and still are waiting on a remedy for this ongoing problem. Our new van has been sitting on a lot for four continuous months now, with no fix in site. I feel that Toyota has not supplied a timely remedy to this safety recall and this is the reason for my formal complaint on this platform today.

UNKNOWN OR OTHER
I own a 2025 Toyota Sienna affected by Safety Recall 25V668 involving second-row seat rails with suspected improper welds. Toyota sent a notice advising that no one should sit in or use a child restraint in the second-row seats until the repair remedy becomes available. However, there is currently no remedy available and no repair timeline. I have contacted both the dealership and Toyota multiple times over the past four months but have not received clear answers or a resolution. The dealership verbally told me I can continue transporting my children, which conflicts with the written safety notice from Toyota. I am a mother of six children and this vehicle is essential for transporting my family. Because the recall involves seating safety and there is no repair available, the vehicle cannot be safely used as intended. I am submitting this complaint due to lack of repair availability and lack of clear communication from the manufacturer.

WHEELS
The TPMS system failed in the ECM or engine computer. It uses the wheel speed sensors on each hub to measure differences in wheel speed and uses this to infer if any one wheel has low tire pressure. (This vehicle does not have TPMS sensors in the wheels.) However, with this failure, it reports a tire pressure problem even though all 4 tires are inflated properly. This problem persists even after cleaning then replacing wheel speed sensors. The problem appears to be in the ECM or engine computer, which is very difficult and expensive to replace. With this problem, the driver is never able to tell if any tire actually has low pressure because the system always reports that a tire has low pressure. Toyota should be required to fix this issue in all affected vehicles.

SEATS, STRUCTURE:BODY, UNKNOWN OR OTHER
My 2025 Toyota Sienna XLE (VIN: [XXX]) is subject to Safety Recall 25V668 related to defective second-row seat rail welds. The recall states that the seat structure may fail during certain high-speed collisions, increasing the risk of injury to passengers. As a result of this safety recall, my vehicle was suspended from passenger rental service on October 6, 2025 and has remained unusable for its intended purpose since that date. Toyota has confirmed that the recall status is “Remedy Not Available,” meaning no repair solution currently exists for this safety defect. The vehicle therefore cannot be safely used for passenger transport and continues to cause significant financial loss while loan payments remain due. I am filing this complaint because the vehicle has been unusable for an extended period of time due to a safety defect with no available remedy.

My husband and I ordered this vehicle last year and picked it up [XXX]. We paid cash and are retired so that was alot. The reason for the purchase was to take our 4 grandchildren on mini trips. For the recall reason we have not been able to do this for obvious reasons, their safety. We received notification in December I believe, I immediately called the dealer. I was advised there is no remedy yet, I have called numerous time to hear the same thing, and not their fault. I ask what to do, they said dont let anyone sit in the rear seats?? scary. I called Toyota customer service on March 2nd, case#[XXX] and was told someone would call within 2 days, I have heard nothing. Our first Toyota and the purchase reason is not available, a scary waste of money for retired people. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

SEATS
This complaint concerns a safety recall affecting a 2025 Toyota Sienna Hybrid involving the second-row seat rails due to suspected weld defects. Toyota has acknowledged the recall and confirmed that a remedy is currently not available. The vehicle was purchased new in May 2025 and currently has approximately 6,600 miles. Due to this safety recall affecting the second-row seating system, the vehicle cannot be safely and fully used as intended. The recall states that the second-row seat rails may have been improperly welded, which may cause the seat to lose structural integrity in certain high-speed collisions, increasing the risk of injury. The manufacturer has confirmed that the recall remains unresolved and that a repair remedy is not yet available. No timeline for repair has been provided. The continued absence of a remedy for this safety-related recall for such an extended period makes it impossible to safely and fully use the vehicle as intended. This complaint is being submitted to document the ongoing safety issue and the prolonged absence of an available remedy.

In October 2025, Toyota issued a recall for MY2025 Sienna Hybrid vehicles due to second-row seat rails that were improperly welded by supplier Toyota Boshoku Kentucky due to a miscalibrated welding machine. The defect means the seat structure may not maintain integrity in a high-speed collision, making the rear seats unsafe for use — including for child safety seats. The recall was confirmed by the dealership. Repair parts are still unavailable as of today, and Toyota has provided no timeline for when the fix will be completed. I have been in a dealership-provided loaner vehicle for over four months that does not meet my family's needs. Toyota's dispute resolution center has not responded to my buyback/replacement request. My children cannot safely use the rear seats of my brand new vehicle. The affected component (seat rail assembly) is available for inspection at the dealership.

There has been a safety recall on the second row seats open since 10/7/2025 making them unusable. There is still no remedy 5 months later. This is unacceptable especially on a brand new vehicle.
