Toyota has issued a voluntary recall to owners of 1998 - 2010 Sienna minivans in states that use salt to counter winter road conditions. The cable that affixes the spare tire under the rear of the Toyota Sienna can become corroded over time. If this cable breaks, the spare tire could fall to the road creating a hazard for other drivers.
Owners in northern states can have Toyota inspect the cable and replace the part if it is found to be damaged. Sienna owners that live in states outside the snow belt are not effected by this recall.
