If you hear chatter/rattle (that isn't the direct injection engine) at a stop, but it goes away when you merely depress the clutch pedal, don't worry about it. I've had two motorcycles and two cars develop this over time. The first car I had to replace around 327,000 miles due to rust, the first motorcycle I had to replace approaching 90k due to high speed rear ender, the second motorcycle is starting to get this on an intermittent basis after 6k and the 2016 FiST bought new has been doing this for years now (also started intermittent) and it's around 60 or 70k. None of the vehicles developed any transmission or clutch issues. The FiST however is different in that, due to slave cylinder design/location, you don't want to hold the clutch pedal in, any longer than you have to. The other vehicles I didn't have to worry about that.
