I've filled up my tank 5 or 6 times but yesterday after filling up the check engine light came on. My dealer, Elliot Bay, informed me this has happened to a couple people when overfilling the gas tank. I did not overfill it, just let the gas pump shut off automatically. The code is P0461, which is for the fuel level sensor circuit. I was able to get the fault cleared at O'Reilly's since the dealer is over an hour away. I also noticed that when the check engine light is on the cruse control does not work. As soon as I got the fault cleared the cruise controls works again.
Not sure if all new cars have a fuel level sensor but I didn't have one in my LR4, that I'm aware of, so first time having to be concerned about overfilling.
