God dammit. My car just started doing this too - right at 60,100~ miles. Perfect timing.I guess I'm joining the party!
Was this all covered under warranty?Just got my car back on 01/04 and I must say the car drives much smoother then before the replacement. In addition to the humming noise, there was also a rattle in 1st gear when engaging (more noticeable uphill from a stop), but I never bothered taking it in. It's been there since I bought the car. Now the humming and rattle noises are gone and the clutch is completely quiet
Engagement is more or less the same, though that might just be due to the new pressure plate. The new fluid was icing on the top, and paired with Acuity bushings all around, the car shifts like butter. I thought it shifted smooth before, but it's even better now.
Here is a list of what was replaced:

They also did an alignment since they had to drop the sub-frame in order to complete the job. It was pulling a bit to the left so that was nice to get done too.
I heard this noise pretty recently for the first time when leaving the gym. It was noticeable right away and I was able to duplicate it the same night from my garage (I'll try to upload a video). It sounds similar to some other vids in this thread, though maybe not as bad.
The original dealership where I purchased the car just told me it was normal and not detrimental to the car or performance at all. They never offered to complete the job out of good faith and the fact that a car with only 50K shouldn't be having clutch noises. Considering I don't abuse my car or drive it hard, I found it hard to believe that the clutch noise was "normal."
I decided I probably needed a 2nd opinion and recalled a co-worker knew someone that worked at another local Honda (ended up being the assistant service manager). I reached out and ended up popping by the next day. The foreman immediately knew what I was referring to and was super helpful and understood my frustration with a relatively new car. After the quick test drive in which we couldn't duplicate the noise, we exchanged contact info and the assistant service manager said she would check on potentially getting it covered.
Turns out I will be be getting the full clutch assembly replaced (apparently it's a revised unit) this coming Tuesday and will hopefully take just a day to get it all done. Either way, they are supplying me with a rental so I don't have to worry about getting around with the car in the shop.
Here's the video I took the first night I heard the noise:
To duplicate the noise reliably.I'll keep an eye on this thread. Don't think I can do anything now since I only hear it occasionally.
Update: I spoke with my dealer yesterday since my car is currently there for another issue. Service advisor said they just had another Si in the shop last week with this issue. He wasn't sure what they replaced, but he's going to find out. Only thing they can do with mine is road test it and see if they can duplicate the noise.
Thanks Teeps. We have a loading dock out back with a ramp. I'll try it later.To duplicate the noise reliably.
Stop the car on an incline (all wheels should be on the incline), front facing up hill. A truck loading ramp will do.
Then it's a matter of starting from a stop in 1st gear, up the ramp.
The noise should occur.
