CONDITION SUMMARY
Situation:
A customer may report a concern that the vehicle does not unlock using the Smart key, then will not start after gaining entry with the Smart key blade. The vehicle also does not display the 'Smart key not found' message when pressing the Start/Stop button. Attempting to start the vehicle, with the smart key in the failsafe starting position, also does not allow the vehicle to start.
This version has been issued for a change to the Warranty Times.
Cause: Component tolerances within the Central Junction Box (CJB) (also known as the Body Control Module (BCM)) may prevent correct functionality during attempts to start the vehicle. Suggested Customer Concern Code C27.
