Buick Envision loud brake squealing when backing out of garage on Buick Envision

Some Buick Envision owners report experiencing loud brake squealing, particularly when backing out of a garage. This issue may stem from several factors, including worn brake pads, which are a common cause of brake noise. Additionally, bad brake rotors can contribute to the squealing sound when brakes are applied, especially in reverse. Some owners also report problems with brake calipers, such as sticking calipers or contact with the rotor disc, leading to loud noises. It is recommended that owners have a professional mechanic inspect the brake system to identify the exact cause of the noise and suggest appropriate solutions, such as replacing brake pads, rotors, or calipers.
