2006 Toyota Prius recalls

6 NHTSA recall campaigns list this model year.

  1. 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.

  2. 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.
