From the date that I purchased the vehicle, the brake system has always been a problem. The brake system has never been smooth. At times, there was creaking noise and loud rumble. When a pedal is applied too quickly, sometime you can feel a little jolt. I brought the car to the dealer several times and each time I was told nothing wrong with the car. I changed the rotor, the disc, and brake pads several times but the problem never is fixed completely.
