MacBook touchpad has randomly cracked when not even using

my MacBook touchpad has cracked on my MacBook I bought brand new from apple last month. it is a MacBook Pro and I have just got home and opened my macbook up and the whole of the touchpad has a crack through it from one end to the other for no reason! I would either like this fixed or a new computer as this should not happen on its own accord, especially not on a brand new MacBook
