CDJ400 Cue Button

Hi, my CDJ400 CUE button seems to sound funny or feel funny, it is loose somewhat though it works fine.
Im just amazed as to how it is already feeling crap and it is Pioneer isnt it supposed to be quality built?
Does anybody know how to fix it ? - it has a "vibratey" loose feel really disappointed with the quality, i do not go outdoor with my stuff and i hardly use it, although I have had them since 2012 OCT. Its not even a fair 2 years.

Call Pioneer. See what they say. I've heard it can be $100 a deck to fix.
