Hello! When I just open and close the rear glass hatch to get stuff out of the back my interior lights never shut off. So I then have to go open and close a door for then to go off.
Is there a faulty sensor back there or a switch is on the wrong setting maybe?

Either the switch at that particular door has gone bad or you have a BCM that is going out. To be sure here are the wiring diagrams and a guide so you can test the circuit and the BCM location with replacement instructions below:
