Chevrolet Impala Limited persistent brake noise when stopping and parking despite multiple dealer visits on Chevrolet Impala Limited

Some Chevrolet Impala Limited owners report experiencing persistent brake noise despite multiple dealer visits, which may stem from various issues such as problems with brake pads, rotors, or calipers. Additionally, grinding noises at low speeds, particularly in parking situations, could indicate underlying brake system problems. Some owners have noted a hissing sound when pressing the brake pedal, which may require inspection and could involve varying repair costs based on the vehicle's model year. Furthermore, issues with the ABS traction control system, including grinding noises while driving and service messages related to traction control and brake assist, can also affect brake performance. It's not uncommon for the first few brake applications after a period of non-use to produce noise due to rust being scrubbed off brake components, which is generally considered normal. Lastly, regular use of the parking brake is advised to prevent it from becoming stuck, which can lead to unusual sounds when the brake shoes are released from the rotor. Owners are encouraged to discuss these concerns with the dealership service department for a thorough inspection and necessary repairs.
