| 05-001-19-3538 | 2019-03-11. Service bulletin. ELECTRICAL SYSTEM; ELECTRICAL SYSTEM:IGNITION. When pressing the START/STOP button in very cold weather, the ignition may not turn off on some vehicles equipped with a lock release button (1) on the selector lever knob. Although the selector lever is in the "P" position and the engine shuts off normally, the ignition may stay on (in accessory mode). NOTE: This TSB only applies if the selector lever knob is BHN2-46-030* or BHN4-46-030* with the lock release button. If not, this TSB does not apply. This may be caused by the lock release button in the selector lever knob sticking in the pressed position. An improper production process is causing an internal part to expand with moisture and interfere with other parts. To eliminate this concern, the production process has been modified. |
