Have had my 2013 edge for just over a month. Went for a cruise in the mountains yesterday and was on a steep winding road at a pretty high altitude. Had to use manual shifting a lot because of steepness, switchbacks, traffic, etc. Anyway, 3 times when parking in different scenic areas when I put the car in park the advance trac system requires service (or something close to that) light came on. Once we got out of the mountains and resumed normal driving the light hasn't come on since. Anyone have any thoughts on this? Thanks.
