2017 Edge Sport - liftgate wouldn't open, tried but just "shrugged" like the latch wouldn't let go. I found the manual release procedure and got it open but it still wouldn't power open. I tried multiple fixes I found here, turned off and on in the menu, charged battery (seems the attempted but unopened state runs the battery down), disconnected/reconnected the battery. After I pulled the 30A liftgate fuse, waited a few minutes, and replaced; it was back to normal. Based on other accounts, I wasn't confident it would continue working. I found SSM 49914 which seemed to address this issue and had the local dealer apply the rear gate trunk module (RGTM) software update. That was apparently the last straw for the module and the dealer quoted $475 to replace it. After I opened the liftgate manually again, the liftgate ajar message wouldn't go off. Other owners have had to replace the latch to get rid of that message. I bought a new latch and a used module ( DG9T14B673AZ) on eBay. I installed the module and everything works again! I plan to replace the latch when the new one comes in case the old one is flaky.
