| GCUS-9-3091 | 2017-12-22. Service bulletin. ELECTRICAL SYSTEM; POWER TRAIN. 14632C Special Coverage. On some vehicles equipped with an automatic transmission, the vehicle's transmission shifter may not properly transmit an electrical signal that allows the ignition key to be turned counter clockwise past the accessory mode to the "LOCK" position after the vehicle has been shifted into park. If this occurs, the ignition key cannot be removed from the ignition cylinder without depressing the manual release plunger located on the underside of the steering column as described in the owner's manual. A key left in the accessory position for an extended period of time may result in severe battery drain and a possible no start condition. In most cases, dealers are to replace the automatic transmission shifter. |
