Squealing is caused by vibration.  On a new car like yours it's likely
that some brake dust had accumulated behind the pads, causing the pad
to vibrate.  Some pads materials are more prone to this than others,
and this is not a malfunction.  A possible "fix" is to remove the
brake pads, clean everything, and then reinstall the pads with some
anti-squeal goop applied to the back of the pads.  Not sure if the
dealer will do this, as there is technically nothing "wrong".  Braking
performance is not affected.
