Failure Date: 10/07/2025

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 pu.

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.

3 Body problem

Failure Date: 10/06/2025

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.

Failure Date: 08/01/2025

The second-row seat rails on my 2025 Toyota Sienna were manufactured with improper welds that can fail in a high-speed collision, potentially causing the seats to lose structural integrity and increasing the risk of severe injury. Safety risk and hardship: due to this defect, Toyota has recommended that no passengers sit in the second row and no child restraints be used in these seats until a remedy is performed. I have been awaiting a remedy for over 70 days, during which time the vehicle's primary utility as a high-capacity family transport has been compromised. This creates a severe accessibility and safety hardship, as I am unable to safely transport my family or use child safety seats in the designated locations. Forcing passengers into the third row, which does not accommodate three carseats side-by-side, is not a safe long-term alternative for our family, especially as at 8 months pregnant, and soon to be postpartum with a newborn and two toddlers in carseats. Reproducibility and inspection: the safety defect was confirmed by the manufacturer (recall numbers 25tb12 and 25ta12) and by my local authorized dealer upon notification. While the vehicle is available for inspection, the manufacturer has acknowledged the defect is due to incorrect weld machine settings at the factory. Symptoms and warnings: there were no warning lamps or messages prior to the recall notification. The issue was discovered by the manufacturer during internal testing between July and August 2024 and publicly announced in October 2025.

Open recall with no anticipated date of being fixed. The second row seats are unsafe for passengers which makes the vehicle unusable for a family.
