The shift interlock system is designed to prevent the shifter from being moved out of the park position unless the brake pedal is depressed. These vehicles are being recalled because during sub-freezing temperatures, the interlock mechanism may be slow to operate. The could allow the shifter to be moved from the park position when it should not be allowed to do so. As a result the vehicle could roll unexpectedly, increasing the risk of a crash. Dealers will install an updated shift interlocking mechanism to correct this concern.
