THE LOW BEAM HEADLIGHTS WENT OUT SIMULTANEOUSLY WHILE I WAS DRIVING AT NIGHT. I PROCEEDED TO THE AUTO PARTS STORE, BOUGHT NEW BULBS AND CHANGED THEM OUT BUT THEY STILL DID NOT COME ON. ALL OTHER LIGHTS ARE WORKING INCLUDING THE HIGH BEAMS. I SEE THERE ARE RECALLS FOR THE SAME PROBLEM LISTED ONLINE FOR 2007 TB'S BUT WHEN I CHECKED WITH GM/BUICK I WAS INFORMED THAT MY VIN WAS NOT LISTED IN THE RECALL DUE TO IT NOT BEING ON THE PRODUCTION LINE AT A CERTAIN PLANT. YET WITH FURTHER RESEARCH THERE ARE NUMEROUS COMPLAINTS FROM OTHER TB OWNERS WITH THE SAME ISSUE AS THE RECALLED VIN'S WHICH SHOULD SHOW THIS IS A PARTS ISSUE. I WAS REFERRED TO THE DEALERSHIP BY GM/BUICK A DIAGNOSTIC OF WHICH I WILL HAVE TO PAY FOR BECAUSE MY VEHICLE WAS ON A DIFFERENT PRODUCTION LINE FOR A PART THAT CLEARLY APPEARS TO BE DEFECTIVE! *TR
