IV. Background

Certain Toyota vehicles that were accessorized at vehicle processing centers operated by Toyota Motor Sales, U.S.A., Inc. (IMS) had accessories installed that caused the weight of the vehicle as accessorized plus the weight of possible passengers to exceed the stated Gross Vehicle Weight Rating (GVWR) value. Therefore, the stated GVWR is insufficient. This condition does not meet federal requirements.

There are approximately 2,100 Sienna vehicles (model year 04 - 09) involved in this SSC. Vehicles will require updates to various labels. In addition, approximately 200 Sienna vehicles will also require the replacement of the original equipment 16 inch wheels and tires with 17 inch tire/wheel assemblies.
