Problem: On certain mini vans, in the middle row seating position, the shoulder portion of the seat belt may bind in the bezel trim piece. The affected seat belt bezel is located on the shoulder portion of the seat in the right side seat of the seven passenger models and the center seating position in the eight passenger models.

Risk: If the seat belt binds in the bezel, that extra webbing may exist in the seat belt which could result in an improperly fitted seat belt on a passenger. In the event of a crash, a seat occupant may not be properly restrained increasing the risk of personal injury.

Fix: Dealers will replace the seat belt bezel and clip. The recall began august 5, 2005. Owners may contact toyota at 1-800-331-4331.
