Hello, I need your help. We bought a 2016 Ford Fusion Energi in June, it drove and charged like normal. About 2 weeks ago, we got a wrench light, then it would disappear. Finally, CEL came one and read P0AA6. Now both wrench and CEL are on, when I plug to 110v it doesn't charge (you don't hear the fan). I took it to the dealership, they said it's the active grille shutter is busted since they found a code P05A1 and for $1300, it will fix my issue. I checked with my OBD scanner before taking it to them, it read P0AA6. So, I fixed the shutter and it's working now. I cleared to CEL and both lights are back on and not charging via plug.
Any suggestions?
