NHTSA Complaint #10716599 — 2009 BUICK LUCERNE

ENGINE FAILS TO START. AFTER RESEARCH ONLINE, CHECKED FUEL PUMP RELAY FUSE AND SURE ENOUGH RELAY BLOWN AND HAD MELTED TO FUSE BLOCK AT ONE PIN ON RELAY. REPLACED FUSE AND CAR STARTED AND RAN LIKE NOTHING WAS EVER WRONG. WITHIN A WEEK THE SAME THING HAPPENED ONLY THIS TIME THE CAR WOULD NOT START AFTER REPLACING THE FUEL PUMP RELAY. HAD CAR TOWED TO BUICK DEALER. THEY REPLACED THE COMPLETE FUSE BLOCK THAT CONTAINS THE FUEL PUMP RELAY WHICH IS LOCATED UNDER THE REAR CAR SEAT. COST ABOUT $840.00 TOTAL ( $40.00 FOR THE 2 FUEL PUMP RELAYS; $75.00 FOR THE TOWING AND THE REST WAS DEALER CHARGE TO REPLACE FUSE BLOCK). ASKED THEM IF THEY FOUND WHAT WAS CAUSING THIS AND THEY SAID EVERYTHING CHECKED OK AFTER REPLACING FUSE BLOCK. HAVE NOT HAD ANY MORE ISSUES SO FAR ALTHOUGH IT HAS ONLY BEEN A COUPLE WEEKS BUT WOULD THINK SOMETHING HAS TO BE CAUSING TOO MUCH AMPERAGE TO BE DRAWN TO HAVE CAUSED THIS. DON'T KNOW IF FUEL PUMP CAN CAUSE TOO MUCH AMPERAGE DRAW. AGAIN, DEALER SAID NOTHING SHOWED UP AFTER REPLACING FUSE BLOCK
