yeah, its part of 'normal wear and tear' (like tires and oil change, etc.)
you don't have much distance AT ALL though, so i'm guessing either something was originally wrong with your clutch...or you burnt it up like crazy.
in any case..the only way you can make toyota replace it for free is if you can prove that it was a defective product to begin with. but since you have 37km on it already thats gonna be one tuff case. most likely you'll just have to buy a new clutch, if the clutch is the problem.
