Power train:automatic transmission
Problem: Toyota is recalling certain model year 2004-2005 Sienna vehicles manufactured January 10, 2003, through August 10, 2005; and model year 2007-2009 Sienna vehicles manufactured February 20, 2007, through December 12, 2008. In the affected vehicles, due to a problem within the shift lock solenoid, there is a possibility that the shift lever could be moved out of Park position without depressing the brake pedal.
Risk: If the shift lever is moved out of the Park position without the brake applied, the transmission will either engage a drive gear or Neutral, increasing the risk of a backover or roll away crash.
Fix: Toyota will mail interim notifications to owners beginning in late October 2013. When parts are available, owners will be sent a second notice and dealers will replace the shift lock solenoid, free of charge. Owners may contact Toyota at 1-800-331-4331.
