TOYOTA issued a recall on the SIENNA model

On certain vehicles operated where road salts are frequently used, excessive corrosion of the spare tire carrier assembly cable may cause the separation of the spare tire stowed under the vehicle. Spare tire falling on the road surface creates a safety hazard that may result in a crash causing property damage, personal injury or death. Correction: Dealers will inspect and, as required, either apply a corrosion resistance enhancement treatment to the spare tire carrier restraint cable, repair the cable and apply the corrosion resistance treatment, or replace the spare tire carrier assembly.
