I took delivery of my Edge ST in late April. The build date was 2/13/19. Right from the beginning whenever I opened any door after the vehicle was sitting for a long time I would hear a weird grating noise coming from under the rear. Not always but particularly after sitting over night. Sometimes I would hear it just unlocking the door even before actually opening it. I took it to the dealer to have them see if they could find the cause. I left it for a few hours. When I picked it up, the dearer said they had gone out to the lot and open the doors on two other ST's. Same noise. They guessed that it was probably just a relay or actuator causing the noise. Has anyone here experienced the same thing. Don't know if it's related to all Edges.
As an aside, I love this vehicle. Doesn't deserve all the bad press. Going to the Edge ST performance event in Utah in October.
