Fan is run by sensors that tell it what to do. They have been known to stick. If you are still under warranty you can have it checked but chances are you will need to having sticking when you take it in.

My engine fan came on under a hard pull going camping. Shut the truck down camped, started it up on Sunday to go home, fan stayed on the whole way home!! About 2 miles from my house the pos released and has been fine ever since. Called Ford and cant do anything about it if it is not broke! I asked the service writter if they had seen any common failures, but he did not have a clue.

Right now, My fan is coming on way more often than normal. Just yesterday, I was coming in from work, doing 75 on I 35, the fan started. It was 107 air temp, hwy temp way higher. When I got off the interstate it stayed engaged for the next 4 miles driving 35 mph till I got home. But again it is hot outside here. This summer, when I was in Colorado, it would also stay on especially in higher elevations. Even though it was 75 or so, it still stayed on and lasted nearly the week I was there. It kept my attention but once I got down to Pueblo, it was intermitted. I had the fan changed last spring on Fords dime so it was a rather new fan assembly. Most say that it is controlled by sensors, but my Job 1 has a Thermal Fan Clutch. The Ford Diesel Tech said you know that by when you start it up, the fan will normally engage until you reach a certain RPM.
If you can spin the fan and it turns 3 times or more freely or if you cannot turn the fan by hand then I would have the fan clutch checked. The following is a link that may help with fan clutches if it is a Thermal controlled silicon based clutch.
