APPLICABLE MODEL(S) / VINS

DESCRIPTION
Some vehicles may exhibit a groan noise from the front brakes when braking at a very low speed
(approximately 6 mph / 10 km/h). This may be caused by a brake torque variation at that speed due to an
inappropriate machining process of the brake disc surface.
Customers having this concern should have their vehicle repaired using the following repair procedure.
REPAIR PROCEDURE
1. Verify customer concern.
2. Replace both front brake discs.
NOTE: The new brake discs are the same as the ones for CX-5 (KE/KF).
3. Verify repair.
