I have a 2013 Fiesta and I am not having any problems, BUT yours should still be under warranty. Take it back to a dealer. They are obliged to rectify the problem regardless of where you live. Not only that, it is a safety issue.

mikeatpriestlake is on target you should invest $20 or more for a code reader. You can get them at most Parts stores, they even have them at a higher cost that use bluetooth to your phone, Definitely an Electrical issue so if you want to do a cursory check look at the fuses for the headlights, and for any loose wire using a gentle pull and shake. There is a relay module as well but before you do that get the Code Reader.
