Official summary
Some customers may experience that the liftgate or the trunk lid will not unlock even when the vehicle is parked and the ignition is off. If the engine is running (POWER ON) or the ignition is turned to on (READY ON), it will unlock. To eliminate this concern, the control software of the DSC HU/CM (or the electronically controlled brake unit) has been modified.
What a TSB means. Technical service bulletins are repair guidance manufacturers send to dealers — they are not recalls, and repairs are not automatically free (warranty extensions are an exception worth checking). The full document is available via NHTSA’s vehicle lookup.
