AI groups complaints by meaning; the groups are approximate. Share ratio compares the problem’s share of this vehicle’s complaints with its share on other vehicles over the last 24 months (shown from 3 recent complaints). A 2× ratio means twice the complaint share, not twice the failure risk. Flags mark unusual shares or recent surges after an AI review of the complaint content. “First signal” does not mean the pattern has persisted continuously.How recall estimates are calculated.

structure
Toyota is recalling certain model year 1998 through 2010 Sienna passenger vehicles manufactured between august 7, 1997 and january 4, 2010, currently registered in or originally sold in connecticut, delaware, illinois, indiana, kentucky, maine, maryland, massachusetts, michigan, minnesota, new hampshire, new jersey, new york, ohio, pennsylvania, rhode island, vermont, washington district of columbia, virginia, west virginia, and wisconsin. The subject vehicles are equipped with the spare tire stowed under the vehicle. If the vehicle is operated in the cold climate regions of the united states where road salt is frequently used, water splashed backwards with high concentrations of road salt Can reach the spare tire carrier and corrode the spare tire carrier assembly cable.
The cable may break due to excessive corrosion and the spare tire may separate from the vehicle, possibly resulting in a vehicle crash.

The safety recall is expected to begin on october 12, 2010. Owners may contact Toyota at 1-800-331-4331.

About this data
NHTSA complaints and recalls through October 2026. Complaints are counted once each, however many components they name. Original complaints are on NHTSA's page for the 2003 Toyota Sienna.
Problem groups are formed by AI and may be approximate. BrakeNews flags unusual complaint patterns; they are not official defect findings. Investigation reports are written and checked by AI, with no human review. Owner reports do not establish that a defect exists.
