SEATS:MID/REAR ASSEMBLY:RECLINER13/02/2025

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."

Risk: An improperly tightened seatback may not adequately restrain the occupant during a crash, increasing their risk of injury.

Fix: 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.
