The official notice
Defect
Toyota is recalling certain model year 2006 through 2011 RAV4 and 2010 Lexus HS250h passenger vehicles manufactured from October 2005 through September 2010. If the nuts for adjusting the rear wheel alignment are improperly tightened during service, the rear suspension arm (rear tie rod) may develop unwanted movement and rust, leading to thread damage and eventual failure. Failure of the rear tie rod will cause an abrupt change in the vehicle's alignment.
Safety Risk
Failure of the rear tie rod could cause a loss of vehicle control, increasing the risk of a crash.
Remedy
Toyota will notify owners, and dealers will inspect the rear tie-rod nut for looseness and replace any suspect tie-rod found loose. Dealers will also affix instructions in multiple places to prevent improper servicing in the future. The recall began on November 30, 2012. Owners may contact Toyota at 1-800-331-4331 or Lexus at 1-800-255-3987.
