I Just got my 2007 hyundai tuson and cd stopped working will it be coverd with warranty?

I just got it the suv and put a cd in for the 1st time listen to it for a couple of weeks and I just changed it. When I did this they are not readind no longer I even put the organial cd pack in and it keeps reading macha. problem. Do you think this will be coverd with my warranty or since I just got the suv and only put on 600 since I got it do you think it will be coverd from the deal (Denny Hecker)?
