I'm not sure if this is the right place to put this. But I had to start somewhere and hopefully the mods can move it to the correct place if need be. So I have a 2017 focus ST. 761 miles. I've babied it the first 500. Given it some gas the next 200. Had an issue pop up at first heard a knocking noise driver side left of engine. Gone. Later heard a ticking noise. At random intervals. Tick...tick tick... tick.. tick tick tick... tick tick. That even disappeared. But I'm wondering what that was and what I should do about it.
