Thanks for your input. Yes, it was happening at idle.
I'm passing on what I was told by the Ford Dealer.
I was instructed to keep my smartphone away from the dash, and I went a step further and chose not to sync or charge my phone while in my vehicle. I figure.. it doesn't hurt anything to do what they recommend. Doesn't cost me a thing to refrain from using my smartphone while in my automobile.
It seemed to work until the day I needed to charge my phone, so maybe they are onto something??
It makes absolutely no sense to me either. At this point, there is nothing I can do until the dealer posts a TSB or it gets worse.
I mentioned the ABS module, and for a reason I can't remember at the moment.. they didn't think the module was the problem. I'm not sure if it would throw a code if the ABS module went out or not??
This winter I had another issue. One day.. I got a message that I had a battery or charging issue. I took my Edge back to the dealer. They checked the battery and charging system, and found nothing wrong.
They mentioned updating software, but I'm still troubleshooting. I hope to have more information collected, then when I do take it in for repair.. they can actually fix the problem.
