My RCF has a slight chirp at idle coming from the drive (serpentine) belt. I believe this has to do with the idler pulley starting to let go. I'm wondering if anyone has DIYed this or has the FSM for this job, it seems fairly easy if it's at all like the IS F. Besides this does anyone have part numbers for the tensioner/belt? Thanks in advance.

Any idler pulley/belt/tensioner I've always done myself. I'd say it's a scale of a 1 out of 10 honestly... I don't see a reason to take it into a dealer to do unless it's under warranty and or you want to burn a bunch of money paying them to do it..

Thanks I'm probably gonna try it myself then, I find it weird that these components would go so early considering my car has just 38k miles but oh well.

Mine chips too. Only when cold though. 62k

People tend to forget that rubber degrades over time as well. If you have a 2015, then that belt is 6 years old regardless of mileage. I had mine replaced at 60k service just as preventative maintenance.
