NHTSA Complaint #11707591 — 2025 TOYOTA SIENNA HYBRID

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 [XXX] pregnant, and soon to be postpartum with a XXX and two XXX 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.
