Vibration sound coming from the front right?

I just bought a 2016 Dodge Charger SXT AWD and I hear a vibration coming from the front right randomly. No specific speed, turning, not turning. I don’t feel it but I hear it almost like I’m driving on rumble strips. To add info, on my way home from work I noticed if I lightly tap the gas and then tap the brake right after it does it for a split second each time. Any tips?
