TOYOTA issued a recall on the SIENNA model

On certain vehicles operated where road salts are frequently used, corrosion of the spare tire carrier assembly cable may cause the separation of the spare tire stowed under the vehicle. The spare tire falling on the road surface creates a safety hazard that may result in a crash causing injury and/or property damage. Correction: As an interim measure, dealers will remove the spare tire and store it in the cargo area of the vehicle. Dealers will replace the spare tire carrier assembly when parts become available. Note: This recall supersedes recall 2010-123. Vehicles that were inspected and/or repaired under the previous recall may still be at risk of spare tire separation and will require re-inspection and/or repair.
