I purchased a new 2016 Edge Sport in June of 2017. Got a great deal as it had been sitting in the showroom since delivery. The AS light would periodically come on when I started the car so I'd turn it off and it would go away. Until I hit about 7000 miles.
I'm glad I found this forum or I'd be pretty concerned. I had traded in my beloved 2014 F150 for this car due to a ridiculous stereo issue that had been ongoing for 2nd years that the dealership couldn't figure out. Sounds as though there's a fix for this problem! I have an appointment on 1/5 so hoping it won't be another year of a loaner vehicle such as I had with my F150.
