NHTSA Complaint #10928083 — 2008 GMC ENVOY

WHILE OPERATING THE 2008 GMC ENVOY ON AN INTERSTATE I OBSERVED WHAT APPEARED TO BE A LACK OF LIGHT WHEN THE LOW BEAM HEADLIGHTS WERE TURNED ON. I DROVE TO A REST AREA AND CONFIRMED THAT THE LOW BEAM HEADLIGHTS WERE INOPERATIVE. THE BULBS WERE REMOVED AND BOTH BULB FILAMENTS APPEARED INTACT. FUSES, BREAKERS AND RELAYS WERE CHECKED FOR SECURE SEATING. THE HIGH BEAM HEADLIGHTS WERE OPERATIVE AND ALL OTHER LIGHTS FUNCTIONED. I AM AWARE OF DOCUMENTATION THAT COVERS THE ISSUE BUT ONLY UP TO THE 2007 MODEL YEAR. THERE ARE OTHER COMPLAINTS ON FILE DESCRIBING SIMILAR ISSUES. THE UNSAFE CONDITION THAT RESULTED WAS THE ABSENCE OF FORWARD LIGHTING WHILE OPERATING A MOTOR VEHICLE DURING TIMES THAT LIGHTING SHOULD BE USED. IT IS MY BELIEF THAT A SOLID STATE RELAY, DELCO PART NUMBER 15016745, IN THE #46 POSITION IN THE ENGINE COMPARTMENT FUSE PANEL, IS APPARENTLY THE CAUSE OF THE LIGHTING FAILURE. NO INJURIES, OR DAMAGES RESULTED FROM THE IN OPERATIVE LOW BEAM HEADLIGHT ISSUE.
