I''ve just purchased a used 2013 Edge and have some issues with the memory function. 1. My wife has hers set (1) and we can be going down the road and the side mirror just moves to another position. Not much but enough it has to be readjusted. 2. My setting (2) is fine until I start the car. For a period of time everything is good until I start the car and the seat moves forward a couple of inches. I have to stop it and adjust it back all the way. Should I take it into a dealer? I can reset both 1 and 2 and everything is okay for awhile then bam, it starts changing. Thanks for any help.
