Toyota Motor Corporation announced a recall of 161,190 [1] Sienta minivans in Japan on Thursday due to a seat-belt buckle wiring defect.
The recall is critical because the failure of a seat-belt warning alarm can lead to passengers driving without proper safety restraints. This increases the risk of injury during a collision, particularly for children in a family-oriented vehicle.
According to reports, the electrical wiring within the seat-belt buckle can break when the belt is repeatedly fastened and unfastened [3]. If the wiring fails, the vehicle's warning alarm may not sound when a passenger fails to buckle up [3].
The affected vehicles were produced between June 2022 and March 2026 [3]. Toyota filed the recall notice with the Ministry of Land, Infrastructure, Transport and Tourism in Japan [2].
Toyota has received 63 reports [3] regarding the defect. While some reports cited approximately 160,000 units [4], the specific figure provided in the filing is 161,190 [1]. The company said it will address the issue by repairing or replacing the faulty wiring in the impacted vehicles.
This action follows a pattern of rigorous safety monitoring in the Japanese domestic market. The Sienta is a popular compact minivan often used for urban commuting and family transport, making the reliability of safety alerts a primary concern for owners.

This recall highlights the sensitivity of modern vehicle safety systems to mechanical wear. By targeting a specific production window and addressing a failure in the warning system rather than the belt's structural integrity, Toyota is mitigating a regulatory risk and potential liability before a major accident occurs due to an unbuckled passenger.
