Not just the socket, but the wiring as well. Though the fuses are same in capacity (20A on my '07), the wiring seems to be inadequate for full loads. A good explanation can be found here:

Welcome! I do see Edges of both generations out and about a lot more this year. Served us well over the past winter About to become handy again with all the hauling for garden work/materials!
Could be. I don't think tire position (think rotation) would make a difference. A sensor could actually have gone bad, but since you are not seeing any driveability issues/other notifications, that does not seem to be the case.
Were any of those miles freeway miles? Try driving for 10 or so miles at/above 90 kph. If that does not work, take it in to any tire store and they can train the system to work together.
