Some 2019 Edge and Nautilus vehicles built on or before 14-Nov-2018 equipped with a power liftgate may exhibit a discharged battery, interior lamps cycling on and off erratically and/or a Liftgate Ajar message in the instrument panel cluster (IPC) when the liftgate/doors are shut. This may be due to the calibration of the rear gate trunk module (RGTM) keeping the module awake. Reprogram the RGTM using the latest software level of the appropriate Ford diagnostic scan tool.
