Cadillac XTS squeaking noise when driving at low speed on Cadillac XTS

Some Cadillac XTS owners report experiencing a squeaking noise when driving at low speeds, which may be attributed to several factors. Low levels of brake fluid can lead to a high-pitched squeal, indicating the need to check and refill the brake fluid reservoir. Additionally, a loose or worn serpentine belt may produce a loud squealing noise, suggesting it could be on the verge of breaking. Some owners also note that loosening front stabilizer bar end link nuts can cause a rattle noise during low-speed driving over bumps. Furthermore, worn brake pads can create a squeaky sound, particularly when metal tabs on the pads rub against the rotor due to wear, signaling the need for replacement. It is advisable for owners to inspect these potential issues to ensure optimal vehicle performance and safety.
