could be, but cant say for sure. do you know how long the Edge was on the lot? Carfax history should give you an approximation, as it will list the date the dealer put it up for sale. If it was sitting for more than a couple of months (even less in extreme weather), very probably the pads started binding to the rotor so there could be chunks of pad on the rotor, not visible but enough to make the braking uneven. Also sounds like the caliper slide pins are not moving freely sometimes, and that means the pistons and hence the pads are not being evenly applied. Also pads COULD be worn, though OEM pads can last a long time.
Summary? Service brakes first. Grease those caliper slide pins. May even want to change pads & rotors TBH. Fresh start. New 2 U does not mean New, unfortunately.
