You didn't mention how many miles are on it.
However, I owned a high mileage(171k) 2012 for 50k miles and currently own a 2013 with over 112k on it and I hear no such sound. My nephew's 2014 also makes no such sound either with like 85k on it.
Take off the accessory belt and start it to see if the sound goes away or not. That'll let you know if it's an internal or external engine issue. The other thing that's an in between would be the timing chain/guides: 2014 FORD FOCUS 2.0L L4 Engine | RockAuto
I'd get a quality mechanic's stethoscope like the Lisle 52500 to pin down where exactly it's coming from.
