HEAD LIGHT FLICKER WHILE DRIVING AND TURNING OR GOING OVER BUMPS. APPEARS TO MAKE DRIVERS THINK I AM FLASHING MY HIGH BEAMS. DEALER COULD NOT DUPLICATE PROBLEM. VERY DISTRACTING WHILE DRIVING, NOT ONLY TO ME BUT PEOPLE WHO ARE AHEAD OF ME. DEALER WAS NOT VERY CONCERNED ABOUT PROBLEM AND SENT ME ON MY WAY. I FEEL LIKE THIS IS A SAFETY ISSUE AND SHOULD BE TAKEN CARE OF. THIS IS NOT AN INTERMITTENT PROBLEM, IT HAPPENS EVERY TIME I DRIVE AT NIGHT. *JB
'03 YUKON DENALI - WHILE DRIVING IN COMPLETE DARKNESS WHILE MAKING A LEFT SWEEPING TURN EVERY VISIBLE INTERIOR LIGHT TURNS OF AND ON FOR 1-2 SEC. THIS INCLUDES HEADLIGHTS. THIS IS BECOMING VERY DANGEROUS AND DISTRACTING TO OTHER DRIVERS. THE DEALER BLAMES IT ON A LOOSE HEADLIGHT SWITCH. THEY REPLACED IT. THAT DID NOT SOLVE THE PROBLEM. ON ANOTHER NIGHT TRIP, THE SAME EVENT OCCURED AGAIN. THE DEALER REPLACED THE ALTENATOR. IT STILL DOES IT. THE DEALER SAYS THEY NOE HAVE NO IDEA. I REALLY NEED HELP. I'M CONCERNED ABOUT COMPLETE LOSS WHILE IN DARKNESS AND SUBSEQUENTLY HITTING A DIVIDER.*AK
