Honda will recall 807,000 vehicles in the United States to fix a defect that could allow them to roll away when a driver thinks it\'s been parked, the Japanese automaker said Wednesday. Honda said it was aware of two incidents in which people received \"minor injuries\" as a result of the defect. After an investigation of several complaints, it determined that the ignition interlock mechanism can be damaged or worn to the point where it\'s possible to remove the key when the transmission hasn\'t been shifted to park. \"If the transmission is not in Park and the parking brake is not set, the vehicle could roll away, and a crash could occur,\" Honda said in a statement. The recall affects approximately 318,000 Honda Odyssey and 259,000 Honda Pilot vehicles from the 2003-2004 model years and roughly 230,000 Acura MDX vehicles from the 2003-2006 model years. Honda will mail notices to owners in February and will conduct all repairs free of charge.
