Toyota is recalling certain model year 2012 Yaris vehicles manufactured August 21, 2011, through August 31, 2011. A relay in the Power Steering Control Module of the electronic power steering system could experience a short circuit due to insufficient distance between terminals in the relay and moisture contamination of relay coil windings. A short circuit in the relay could disable power steering assistance.
If the power steering assistance shuts off, the driver may have difficulty steering the vehicle at low speeds, increasing the risk of a crash.
Toyota will notify owners, and dealers will replace the power steering control module. The recall began on July 31, 2013. Owners may contact Toyota at 1-800-331-4331.
