Wheel out of balance is likely. First thing is to do a visual and check for wheel damage or if any wheel weights have come off. It can happen if the car has had enough hard braking to heat up and loosen the weight adhesive.
Next step is to find a good Balance machine (Hunter) and have them checked. With a car that new some dealers will cover a rebalance under warranty.
