Brake pulsation is very common, especially in later models. It can happen at any time, and alot of factors contribute to it. The brakes are not necessarily bad(although it could need pads on one axle or the other), it just indicates some lateral runout(warpage) in the rotors. It can be corrected by resurfacing the rotors(assuming there is some serviceable life on them).
