Quite simply, your never going to get a perfect car! thats the nature of a machine! however it shouldn't have happened on such a new vehicle, take it back and ask for it to be sorted. If you have any problems then I would recommend calling consumer advice on what your rights are, as if I am not mistaken, as long as they are going to rectify it then you can't just ask for your money back unless its catastrophic.

Good luck! it seems as though there are some real haters with pointless views on this thread!
