This Preliminary information communicates that a customer may experience a moan or vibration at low speed maneuvers or brake apply caused by V\-Series vehicles being equipped with high performance track capable brake lining that generates high brake torque during a brake event. Revised Upper Control Arms will be released in 2020 to address. The noise will not effect the performance or reliability of the vehicle.
