Some Mazda CX-5 owners report experiencing issues such as premature rear brake failure, which has been commonly highlighted in numerous reports. Additionally, some owners notice a grinding noise that may stem from wear indicators on prematurely worn outer rear brake pads. Caliper problems, particularly with rear brake calipers causing dragging, have also been identified in certain models, including the 2016 CX-5. In some instances, frozen caliper brackets on the rear driver's side have resulted in excessive heat generation, leading to premature wear of brake pads and rotors. Furthermore, if a groaning or squeaking noise occurs when applying the brakes, it is advisable to refinish the brake pads or replace them with new parts. These concerns underscore the importance of regular maintenance and prompt attention to any unusual sounds or performance issues in the braking system of Mazda CX-5 vehicles.

A rattling noise from under the vehicle can be caused by a loose exhaust header pipe heat shield.
