Toyota is recalling certain model year 2010 Lexus RX350 and RX450h vehicles, manufactured from November 28, 2008, through September 1, 2010, and model year 2008 through 2011 Toyota Land Cruiser vehicles manufactured from September 1, 2007, through September 5, 2011. In July 2012, Toyota filed a defect report to recall certain model year 2010 Lexus RX350 and RX450h vehicles. In November 2012, Toyota informed the agency that it was including an additional 10,565 vehicles including certain model year 2008 through 2011 Toyota Land Cruiser vehicles. The total number of vehicles being recalled is now 164,601. The accelerator pedal can get stuck in the wide open position due to its being trapped by an unsecured or incompatible driver's floor mat.
Risk: A stuck open accelerator pedal may result in very high vehicle speeds and make it difficult to stop the vehicle, which could cause a crash, serious injury or death.
Remedy: Toyota and Lexus will notify owners of affected vehicles and dealers will modify or replace the accelerator pedal and replace any driver's floor mat not specified for the vehicle. Owners of the Lexus vehicles were notified during August 2012. Toyota has not yet provided a notification schedule for the additional Land Cruiser vehicles. Owners may contact Toyota Customer Experience Center at 1-800-331-4331 or Lexus at 1-800-255-3987.
