NHTSA Complaint #10970974 — 2007 BUICK LUCERNE

HEAD LIGHT FAILURE DUE TO PASSENGER SIDE RELAY HARNESS MODULE FAILURE. LOW BEAM LIGHTS FAILED ON DARK NIGHT ON MOUNTAIN ROAD. THIS PROBLEM HAS BEEN REPORTED BY NUMEROUS BUICK LUCERNE DRIVERS. BUICK OBVIOUSLY KNOWS THERE IS A PROBLEM BECAUSE THEY OFFER A REPLACEMENT FRONT LIGHT HARNESS MODULE THAT MUST BE SPLICED INTO THE EXISTING MAIN LIGHT HARNESS TO REPLACE THE ORIGINAL EQUIPMENT MODULE. THIS IS AN OBVIOUS MANUFACTURING DESIGN DEFECT AND A DIFFICULT MODULE TO REPLACE. THE REPLACEMENT MODULE IS APPROXIMATELY $50 AND THE REPLACEMENT LABOR IS AROUND 1.5 HOURS. WITH NORMAL USE THIS LIGHT MODULE CONNECTIONS SHORTS OUT BECAUSE OF THE OVERLOAD ON THE MODULE. WHY HASN'T THIS PROBLEM BEEN CONSIDERED FOR A RECALL? GM HAS ADMITTED IT IS A DESIGN DEFECT WITH THE AVAILABILITY OF THE REPLACEMENT LIGHT HARNESS MODULE WIRING KIT. MY WIFE ALMOST WENT OFF THE ROAD AND WRECKED WHEN THE LIGHTS WENT OUT.
