Model years: 2003, 2004, 2005, 2006

Problem: Honda is recalling certain model year 2003 and 2004 Pilot and Odyssey and 2003 through 2006 Acura MDX passenger vehicles manufactured from November 26, 2001, through August 30, 2006. The interlock lever of the ignition switch may deform, which can allow the interlock function of a vehicle with an automatic transmission to be defeated.

Risk: Removal of the ignition key when the gear selector of a vehicle with an automatic transmission has not been shifted to the park position can allow the vehicle to roll away, increasing the risk of a crash.

Fix: Honda will notify owners and instruct them to take their vehicle to a Honda or Acura dealer. The dealer will install an updated shift interlock lever and, if necessary, replace any necessary part of the ignition switch, free of charge. The recall began on February 22, 2013. Owners may contact Honda at 1-800-999-1009.
