2009 Toyota Prius recalls

6 NHTSA recall campaigns list this model year.

  1. NHTSA 13V014000Jan 16, 2013Structure & Body3,235 vehicles

    Seats

    Southeast Toyota Distributors, LLC (SET) is recalling certain models interspersed through model years 2009 through 2013 as follows: model year 2009-2012 Tacoma, 4Runner, Camry, Camry Hybrid, Prius, and RAV4; model year 2009-2010 Avalon, FJ Cruiser, and Highlander Hybrid; model year 2010-2013 model year Corolla, Sienna and Tundra; model year 2009-2013 Highlander and Venza; model year 2012 Prius V; and model year 2010-2012 Sequoia. During modification by SET to include accessories such as leather seat covers, seat heaters or headrest DVD systems, these vehicles may not have had the passenger seat occupant sensing system calibration tested. Without passing the calibration test, the occupant sensing system may not operate as designed.

    Risk: If the front passenger seat occupant sensing system is out of calibration, the front passenger airbags may not deploy or they may deploy inappropriately for the passenger's size and position. This could increase the risk of personal injury during the event of a vehicle crash necessitating airbag deployment.

    Remedy: Southeast Toyota will notify owners, and dealers will test the sensitivity of the occupant detection sensors, and recalibrate them as necessary. The recall began on March 21, 2013. Owners may contact Southeast Toyota at 1-800-301-6859.

  2. NHTSA 12V537000Nov 14, 2012Steering669,705 vehicles

    Steering:gear box:shaft sector

    Toyota is recalling certain model year 2004-2009 Prius vehicles manufactured August 5, 2003, through March 30, 2009. The affected vehicles have a steering intermediate extension shaft assembly built with metal splines that complete the connection from the steering wheel to the steering gear. These splines may have been manufactured with an insufficient hardness.

    Risk: Over time, the splines may wear and eventually fail resulting in a loss of steering ability, increasing the risk of a vehicle crash.

    Remedy: Toyota will notify owners, and dealers will inspect the extension shaft and replace it if it is one with insufficient hardness, free of charge. The recall began during December 2012. Owners may contact their Toyota dealer or the Toyota Customer Experience Center at 1-800-331-4331.

  3. NHTSA 12V536000Nov 14, 2012Fuel System350,662 vehicles

    Hybrid propulsion system: inverter

    Toyota is recalling certain model year 2004-2009 Prius vehicles manufactured August 6, 2003, through March 30, 2009 and FCHV-adv vehicles manufactured December 12, 2008, through September 13, 2011. During manufacturing, a scratch may have occurred inside of the electrically driven water pump at the coil wire. The coil wire may corrode at the scratched portion.

    Risk: The corroded coil wire may break and the water pump could stop. The corroded coil wire could cause a short circuit between coil wires and a possible open fuse, creating a stall-like condition of the hybrid system while the vehicle is being driven. This may increase the risk of a vehicle crash.

    Remedy: Toyota will notify its owners, and dealers will replace the electric water pump, free of charge. The recall began on January 17, 2013. Owners may contact their Toyota dealer or the Toyota Customer Experience Center at 1-800-331-4331.
