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