Well just experienced the same problem on my 2010 Edge SEL. At the beginning I was going to deal with it, but when it happened three times in a row took it to dealer. They couldn’t find any problems with evaporator system or indication, so they contacted Fleet engineer. Respond was to replace fueling pipe and see if it helps. The vehicle was over dealer for almost a week, (they gave me a loaner) just waiting for part from Canada. Took them about two hours to replace it. Fuel it to full, so far no problem, will update at next fueling.
