Last year we discovered clunking noises when going over bumps even at low speeds. We were told that it was most likely broken springs in the front end (by a Hyundai dealer-without looking at or driving the car). Clunking is getting worse and more frequent. Does this sound like a correct diagnosis? Brakes seem to fail on occassion but work when pumped. Just had all new brake/rotors etc last fall. Ideas?
