Toyota Sienna Minivan Defect Class Action Lawsuit

Toyota Sienna Minivan Defect Class Action Lawsuit — Product Liability class action lawsuit

Case Overview

The lawsuit involves allegations against Toyota Motor Sales USA Inc. and Toyota Motor North America Inc. concerning the 2025 Toyota Sienna minivan. Five consumers, led by Adam Hamblin, initiated the class action after discovering that internal testing by Toyota in the summer of 2025 revealed that the welds on the second-row seat rails were not fully penetrated, potentially compromising the seats' structural integrity in high-speed crashes.

The plaintiffs contend that Toyota's repair-only warranty failed its essential purpose because the company allegedly took over five months to begin repairs and required owners to leave their vehicles unattended at dealerships. The claims center on the alleged welding defect and the failure of the warranty to provide timely repair or replacement of the vehicle.

The case is currently moving forward in the California federal court after a judge largely denied Toyota's motion to dismiss. The five plaintiffs seek to represent a class of owners who purchased or leased the minivan with the defective seat rails. The plaintiffs are represented by Trinette Gragirena Kent and Stephen F. Taylor of Lemberg Law LLC.
