Diagnostic Trouble Code (DTCs) -- Trouble codes are how OBDII identifies and communicates to technicians where and what on-board problems exist. The first number in the DTC indicates whether the code is an SAE generic code (applies to all OBDII systems) or is specific to the vehicle manufacturer.
Give your dealership a call of goooooogle the code itself.
I'd say just give the dealer a call and see what they say. You can try to google it for self knowledge but I mean... you have warranty, utilize it. If the car isn't driving properly anymore than there's a serious issue, it it's still working right, shouldn't be too much to worry about, just get it in there.
