My 2013 Edge is in the shop as I type to have the throttle body replaced. I can tell you the list of symptoms that I experienced and hopefully this will help some of you others. I have 29,000 miles currently on the vehicle. I took it in initially because I noticed it to be shifting hard (almost like a slip) generally from 2nd to 3rd gear. It really just felt unstable at times, including when coming to a downshift and then a quick upshift again, it would hesitate or kick. When they looked at it they found that the transmission fluid was a quart low with no visible signs of leak whatsoever. Addressing that did not solve the issue, so they then reset the "adaptive learning" capability of the edge to see if that would help since I bought the vehicle used. That also did not help. I had also noticed that the gas mileage was getting consistently worse, I was barely getting 16 to 17mpg on average. In the shop yet again, and they called to tell me that the throttle body was bad and needed to be replaced. They stated this would cause all of the above symptoms. I have a family member who works for this service dept and I have done a commercial for the dealership/service dept so I know they would not be giving me the typical run-around that some experience.
They gave me another 2013 edge to drive as a loaner and it really made me realize just how poorly mine had been shifting gears and sucking gas, but I have noticed in this loaner vehicle that it surges RPM's while at idle, so I would guess that this vehicle will also have a failed throttle body in the near future. It is definitely a flaw in the throttle body and I would not at all be surprised to see a recall on this in the next couple of years. I will post an update after the I get the vehicle back and see how its driving.
Hope this helps some of you out.
