NHTSA Complaint #10078900 — 2003 CADILLAC CTS

MY VEHICLE DEVELOPED A HUMMING NOISE COMING FROM THE REAR DIFFERENTIAL AT 30,000 MILES. THE DEALERSHIP FOUND THAT MY REAR DIFFERENTIAL WAS FULL OF METAL AND STATED THAT THE WHOLE DIFFERENTIAL MUST BE REPLACED SINCE THE METAL CHURNING THROUGH THE GEARS RUINS THE WHOLE UNIT. 7,000 MILES LATER THE NOISE RETURNED. THE DEALER AGAIN FOUND METAL IN THE DIFFERENTIAL, BUT THIS TIME CADILLAC TOLD THEM TO SIMPLY PUT SOME SPECIAL LUBRICANT IN IT! ALL THIS, AFTER THEY TOLD ME LAST TIME THAT THIS TYPE OF PROBLEM REQUIRES REPLACEMENT, AND NOTHING LESS. I WAS TOLD TO DRIVE MY CAR FOR A FEW WEEKS AND SHOCKINGLY ENOUGH, THE MAGIC LUBE DID NOTHING FOR THE PROBLEM. AFTER READING SEVERAL REPORTS FROM PEOPLE WHO HAD THE REAR DIFFERENTIAL OF THIS CAR SIEZE UP(EVEN CAUSING ACCIDENTS), I APPROACHED THE DEALERSHIP FOR A LOANER. I WAS DENIED A LOANER, AND THE MANAGER HAD THE NERVE TO TELL ME THE NOISE WAS NORMAL. WHY ON EARTH THEY FIXED A "NORMAL" CAR THE FIRST TIME IS BEYOND ME. WHEN I ASKED THEM TO SHOW ME ANOTHER CAR ON THE LOT THAT MAKES THE SAME NOISE, THEY BACKED DOWN. PLEASE HELP WITH THIS ISSUE. I AM AFRAID TO DRIVE MY CAR! *JB
