Quick answer

Some customers may experience the following concerns: 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. The auto close operation of the power liftgate is not performed (The liftgate can be closed manually). To eliminate this concern, the control software of the DSC HU/CM (or the electronically controlled brake unit) has been modified. Customers
