Car is turned off, key is removed yet engine still runs for 30 seconds or more.
Body Control Module has already been replaced due to multiple battery draining issues. Any advice?

From what I can see in the wiring diagram (Attached Below) i t could be the BCM, Ign Switch or possible the Run/Crank Relay. Best bet would be to test the brown wire out of the switch after it is shut off to see if it still has power, that will eliminate the switch. From there you will need to test the run/crank relay to see if it is still energized (Bad BCM?) If no power from switch

Did it do this before BCM was replaced?

Read the guides below on testing wiring and relays, they will help
