Service bulletin PIC6377A

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary

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.
