For the 2015 order, i dont think so you would get to know any issues. Your order will be put in as 2015 and the car is not due until Oct. or Nov.
So its highly unlikely anyone would know about issues with 2015.
But there is one thing for sure.. All the issue that people faced in early models were fixed in April 2014 onward built so the new built would have even more issues fixed. Also the premium audio would be fixed by then as well hopefully.
