    Toyota Motor Engineering & Manufacturing (Toyota) is recalling certain 2005-2007 and 2009-2010 Toyota Sienna vehicles. In the affected vehicles, due to a problem within the shift lock assembly, the shift lever may be moved out of the 'Park' position without depressing the brake pedal.

    Risk: If the shift lever can be moved from the "Park" position without depressing the brake pedal and the parking brake is not applied, the vehicle may roll, increasing the risk of a crash.

    Remedy: Toyota will notify owners, and dealers will replace the shift lock solenoid and reapply the grease, free of charge. Owners may contact Toyota customer service at 1-800-331-4331. Toyota's number for this recall is H0V. Vehicles that were previously recalled under campaign 13V-429 are not affected by this recall.
