I have had this fuel filler problem since buying my 2017 Fusion 2 months ago. The pump shuts off about 30 times before it finally fills up. I brought it to the dealer today and they just called me and said it fills with no problem for them. That doesn't make any sense. I have used many different gas stations in four different states while on a trip to the Smokey mountains and had the same problem every time.
I tried many different angles, filling slowly, pulling nozzle in and out, putting pressure on nozzle. No difference.
I have used at least five different gas stations around the area and no difference. It takes forever to fill.
