NHTSA Complaint #10161244 — 2003 CHEVROLET IMPALA

2003 IMPALA LS - HEADLIGHTS GO OFF WHILE DRIVING. JUST SHUT OFF. DOESN'T MATTER IF MANUAL HEADLIGHT SWITCH IS ENGAGED OR NOT. INTERMITTENT FAILURE, SOMETIMES NOT FOR TWO HOURS, SOMETIME EVERY FEW SECONDS, SOMETIMES WHEN SWITCHING LOW TO HIGH BEAMS, NO SPECIFIC SPEED OR DRIVING CONDITIONS. ALL INTERIOR LIGHTS AND PARKING LIGHTS APPEAR TO REMAIN ON WHEN THE HEADLIGHTS FAIL. SOMETIMES CAN GET HEADLIGHTS BACK ON BY SWITCHING OFF AND ON AGAIN, SOMETIMES BY FLASHING LOW TO HIGH, BUT THEY DON'T ALWAYS COME BACK ON REGARDLESS OF ACTION. SOMETIMES JUST HAVE TO PARK THE CAR UNTIL DAYLIGHT. CAR HAD JUST OVER 44,000 MILES ON IT WHEN I BOUGHT IT. DROVE FOR TWO WEEKS, BUT NEVER AT NIGHT, SO NOT EXACTLY SURE OF MILEAGE OF FIRST INCIDENT. HAPPENED SECOND TIME I DROVE THE CAR AT NIGHT. UNABLE TO REPEAT INCIDENT AT DEALER, BUT CAR WAS IN "PARK" WHEN THEY LOOKED AT IT, AND IT WAS DAYTIME. IT COULD BE HAPPENING WHILE DAYTIME, TOO, BUT I CAN'T TELL FROM INSIDE THE CAR. I COULD GET A TICKET IN MARYLAND FOR DRIVING WITH NO HEADLIGHTS WHILE USING WINDSHIELD WIPERS. *NM
