AggieRed2016 - I'm no professional when it comes to paint... but I HAVE seen this before and it was due to improper prep before applying the paint. I do NOT believe that's the factory paint flaking off. I think the car was probably damaged as a rental and they repaired before being resold to the public. Carfax is not always 100% accurate. There are a LOT of repairs that happen out there which are never reported to carfax. You can take it to a Ford dealer since it's under warranty and let them diagnose whether that's actual factory paint peeling off, or just a shoddy repair. If they determine this is not factory paint chipping off then you'll need to go back to where you purchased the car and take it up with them. If it is the factory paint peeling off (shame on you Ford) then it should be covered under warranty if the car is under 1 year old and has less than 12,000 miles.
P.S. I just looked at your pictures really close and it sure looks like that rear fender was damaged and repaired. If you look at the wheel well arch you can see the body line is not sharp and pronounced. Plus it definitely looks like "filler" at the very top portion of where the paint peeled.
