This can be due to an internal mechanical or electrical fault in the rear back door latch/actuator itself.I have seen this fail before in the past needing replaced for this issue here.This will have to be checked/tested further to be sure this is the cause here.The interior door paneling usually needs removed to try and manually release the door then the latch/actuator tested/checked to see if it needs replaced which I suspect it does.In some cases this fault can be due to broken wiring leading from the body to the door with the wiring needing inspected and repaired.
