NHTSA Complaint #10150326 — 2003 GMC YUKON DENALI

AFTER NOTICING THAT MY 2003 YUKON DENALI HAD INTERMITTENT HEADLIGHTS/DASH LIGHTS DIMMING, I TOOK THE VEHICLE TO MY LOCAL DEALER TO HAVE IT CHECKED OUT. THEY PRESENTED ME WITH A DOCUMENT THAT STATED THE GM STATED THIS WAS NOT A MALFUNCTION AND WAS A NORMAL CONDITION. THERE IS NOTHING ABOUT THIS THAT IS "NORMAL". ANY TIME, AT NIGHT, A CURVE IS TAKEN AT ABOVE 35 MPH THE LIGHTS FLICKER. I HAD ALREADY PINPOINTED THAT IT HAD TO DO WITH THE VSES SYSTEM BECAUSE WHEN THE VSES IS TURNED OFF, THIS DOES NOT HAPPEN. WHEN A CURVE IS TAKEN AND THE FLICKERING OCCURS, THE VOLTAGE METER FOR THE BATTERY DROPS SUBSTANTIALLY AND THEN GOES RIGHT BACK TO NORMAL. THIS IS A DISTRACTION FOR THE DRIVER (MYSELF), ANY ONCOMING TRAFFIC, AND ANYONE THAT I AM BEHIND. THIS ABSOLUTELY NEEDS TO BE LOOKED INTO BEFORE IT CAUSES INJURY. *JB
