Yes it is very upsetting when a problem comes up on a new machine, and no matter what the dealer should take a look at it for free in my opinion. This could be lots of issues, and the battery is taking the blame. You need to do some research, before condemning the battery. Charge it up, see if it starts, if it does disconnect it overnight or over the weekend, then reconnect it, and if it starts, then you likely have a drain on it, and that should be a dealer warranty issue, I think. Good luck!
