Nonsense. Your bumper-to-bumper warranty doesn't expire til 32k miles, and your power train warranty doesn't expire til 60k miles. Dealerships will try to tell you different because they have no idea what they are talking about and don't want to do extra work on your car "for free" (which Honda Co. actually ends up paying them more than standard rates for their labor, so they actually make money on doing these sorts of repairs).
If you are experiencing anything you think is a problem, like odd clutch noises, the manufacturer is obligated to fix them. Go practice on a hill near where you live and see how you need to let out the clutch with a little gas to make the noise happen; This is a common problem with '12+ Si's, and Honda knows it by now. If you can demonstrate the problem, they will replace your entire clutch assembly for free (what would otherwise be a $2000+ job). If you have this done, I also suggest you replace your rear engine mount with a Hasport anything, as they are much more solid mounts to compensate for the fact that Honda eliminated an entire mount when transferring into this model (there were 4, now there are 3); I personally believe the weak factory rear engine mount has a lot to do with our failing factory clutches, as I have seen zero issues with the replacement clutch when I replaced these parts near the same time I put in the new motor mount. Also, the difference just in everyday driving is significant, which also leads me to the same conclusion: the weak stock rear motor mount is responsible for many issues our '12+ Si engines face.
