- SEATSNHTSA 25V086000Feb 13, 2025
Toyota Motor Engineering & Manufacturing (Toyota) is recalling certain 2021-2025 Sienna Hybrid vehicles. The bolts for the seatbacks on the third-row seat assemblies may not be tightened properly. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) numbers 202, "Head Restraints," 207, "Seating Systems," and 225, "Child Restraint Anchorage Systems."
Consequence: An improperly tightened seatback may not adequately restrain the occupant during a crash, increasing their risk of injury.
Remedy
Dealers will tighten the seat assembly bolts, free of charge. Owner notification letters were mailed April 1, 2025. Owners may contact Toyota's customer service at 1-800-331-4331. Toyota's number for this recall is 25TA05.

Reliability verdict for the 2021 Toyota Sienna
The 2021 Toyota Sienna posts an above-segment reliability score, indicating solid overall dependability relative to peers. With a limited recall count, the data points to a generally controlled risk profile rather than widespread systemic problems.
Complaint activity is not evenly spread across the vehicle. Reports cluster heavily around air-bag-related concerns, while the remaining issues appear in smaller pockets involving visibility/wiper performance, seats, structure, and exterior lighting. That concentration suggests the ownership risk is more about a specific system than a broad pattern across major vehicle functions. As the first year of a new generation, the data still reads as above average.
Overall, risk level is moderate-to-low, with attention centered on a single dominant category.
