The front rotor warp excessively causing the brake pedal and the entire car to shake uncontrollably. The entire front brake assemblies were replaced at Subaru of Coconut Creek. Our safety was definitely at risk as it was very hard to brake going downhill with the brake pedal and the car shaking uncontrollably. The dealer confirmed black spots on the front rotors and warped front rotors. There were not warnings prior to, during, or after the shaking. Going downhill was made very uncomfortable. Subaru of Coconut Creek services the vehicle and notified me of the black spots and warped front rotors. There was nauseating burning smell coming from under the hood and we had to wait 15 minutes for it to disssipate.
