The electric cargo door is malfunctioning.
The Body Control Module or BCM, controls the sliding doors. There have been instances where the BCM has failed causing the door not to operate. One thing that can be done is to reset the BCM by removing its fuse for 5 seconds and then re-installing the fuse. If door operation resumes the BCM is most likely the issue and may need to be replaced at a later date. If this does not rectify the problem then further diagnosis will need to be carried out. You may want to enlist the help of a mechanic, like one from YourMechanic, who will have the training and access to the wiring diagrams to diagnose the electrical issue and recommend the proper repair.
