04-002-252025-08-05. Service bulletin. SERVICE BRAKES. Some vehicles may exhibit a clunk noise from the rear brakes when starting to drive. This may be caused by the brake pads and the rear disc plates sticking together when the Electric Parking Brake (EPB) is engaged for an extended period while parked. Even after releasing the EPB, the adhesion remains. When the vehicle starts driving in this condition, the initial torque causes the brake pads to detach from the rotors, and the resulting impact is transmitted through the brake system to the vehicle body, resulting in a clunk noise. To eliminate this concern, the shape of the rear brake disc pads has been modified to increase the rigidity and reduce the impact force.
