Some customers may comment that the Instrument Panel Cluster performs a running reset or WOW display during OnStar® usage. The customer may notice that the IPC will momentarily sweep the gauge pointers to zero (home position) and illuminate all the telltales as if they had started their vehicle. The IPC does return to normal operation after the WOW.
