2003 Cadillac Cts

I AM AND HAVE BEEN EXPERIENCING NUMEROUS FAILURES WITH MY VEHICLE. I HAVE CONTACTED GM NUMEROUS TIMES BEGINNING APPROXIMATELY A FEW MONTHS AFTER I PURCHASED THE VEHICLE TO INFORM THEM THAT THE VEHICLE IS DEFECTIVE, ONLY TO BE TOLD MY VEHICLE IS OUT OF WARRANTY, SO THEY REFUSE TO FIX IT OR GIVE MY ONE THAT IS NOT DEFECTIVE. MY VEHICLE IS STILL DEFECTIVE TO THIS DATE. *TR

WE OWN A 2003 CTS CADILLAC WITH 40,000 MILES AND STILL UNDER WARRANTY. I HAVE HAD THE CAR IN FOR REPAIR SEVERAL TIMES FOR THE SAME REASON. THE CAR SHAKES AT CERTAIN SPEEDS. EG. 47, 59,65,69, AND 75 MILES PER HOUR. THE WHEEL ACTUALLY SHAKES IN MY HANDS. IT IS A PROBLEM WITH THE TRANSMISSION. CADILLAC STATED IT WAS CHARACTERISTIC OF THE 2003 CTS. MAYBE AN ESCORT BUT NOT A CADILLAC. THEY OFFERED TO EXTEND THE WARRANTY ON THE TRANSMISSION TO 100,000 MILES. WHOOPIE. I NOW MUST DRIVE A CAR THAT I FEEL IS DANGEROUS TO DRIVE. I REALLY BELIEVE THE TRANSMISSION WILL TOTALLY FAIL AND SOON. IT GETS WORSE AND WORSE. THANKS FOR VIEWING THIS LETTER. *JB

DT: VEHICLE LOST POWER WHEN THE CONSUMER HIT THE BRAKES. THE TRANSMISSION JOLTS AND THEN THE ENGINE SHUTS OFF. IT HAS BEEN TO THE DEALER 6 TIMES SINCE JANUARY. THE DEALER TRIED SOMETHING DIFFERENT EVERY TIME SHE TOOK IT IN. MANUFACTURER SAID SHE COULD HAVE A NEW VEHICLE IF SHE PAID FOR IT. SHE WANTED TO GET RID OF THE VEHICLE.*AK THE CHECK ENGINE LIGHT ILLUMINATED. *JB

HAVE 2003 CADILLAC CTS, HAD THE DIFFERENTIAL REPLACED BECAUSE IT WAS HOWLING & GETTING WORSE (THIS IS COMMON COMPLAINT BY OWNERS OF 2003 - 2005 CTS MODELS - SEE CADILLAC USERS GROUP, CTS FORUM). PICKED UP CAR AFTER DIFFERENTIAL WAS REPLACED. DROVE APPROXIMATELY 2 MILES FROM DEALER WHEN DIFFERENTIAL LOCKED UP AT 50 MPH. MANAGED TO CONTROL SLIDE/SKID AND SLIDE OFF FOUR-LANE ROAD SURFACE WITHOUT HITTING OTHER VEHICLES, BUT HAD IT HAPPENED A MILE FURTHER DOWN THE ROAD, I'D HAVE BEEN ON I-85 IN HEAVY INTERSTATE TRAFFIC AT 70 MPH... DEALER REPLACED FAILED REAR END WITH ANOTHER NEW ONE WHICH, THUS FAR (500 MILES OR SO) IS TROUBLE-FREE, BUT IN VIEW OF THE PROBLEMS I & OTHERS HAVE EXPERIENCED WITH THESE UNITS, I HAVE LITTLE CONFIDENCE THAT THE BASIC PROBLEM HAS BEEN RESOLVED. UNCOMFORTABLE AT THOUGHT OF DEPENDING ON VEHICLE FROM BOTH SAFETY & BASIC TRANSPORT ASPECT - RELUCTANT TO CONTEMPLATE A LONG DISTANCE TRIP FOR THESE REASONS. CALLED CADILLAC & THEY SENT A WARRANTY RIDER EXTENDING COVERAGE OF THE DIFFERENTIAL/CARRIER ASSEMBLY TO 2010 OR 100,000 MILES, WHICH IS USEFUL. HOWEVER, GM MINDSET SEEMS TO BE THAT IT IS CHEAPER TO REPLACE THESE UNITS AS THEY FAIL WITH NEW UNITS WITH THE SAME FLAW , THAN IT IS TO DETERMINE WHY THEY ARE FAILING, CORRECT THE FLAW & PROVIDE OWNERS WITH REDESIGNED, SAFE UNITS. I MAY BE OFF A BIT ON THE ACTUAL DATE OF THE INCIDENT INVOLVING FAILURE OF DIFFERENTIAL AS MY DEALER, CLASSIC CADILLAC IN MONTGOMERY, AL, HAS NOT AS OF YET PROVIDED ME A COPY OF THE PAPERWORK DOCUMENTING THE INCIDENT & INSTALLATION OF THE THIRD DIFFERENTIAL. I CALLED MY SERVICE REP YESTERDAY & HE APOLOGIZED FOR THE "OVERSIGHT" & SAID THEY'D MAIL ME THE DOCUMENTATION. THE DIFFERENTIAL THAT SEIZED IS NOT AVAILABLE - I TOLD THEM I WANTED TO SEE IT, BUT WAS INFORMED THAT THEY HAD TO SEND IT BACK IN ORDER TO GET ANOTHER REPLACEMENT. *NM

THERE NEEDS TO BE AN IN-DEPTH INVESTIGATION REGARDING THE NUMBER OF CTS AND CTS-V REAR DIFFERENTIALS THAT HAVE BEEN REPLACED. I HAVE NOW BEEN THROUGH 2 PERSONALLY, AND AN ONLINE POLL OF 65 CTS-V OWNERS SHOWED THIS: 26% HAVE HAD 1 REPLACEMENT, 5% HAVE HAD 2 OR MORE REPLACED, AND 8% HAVE HAD 3 OR MORE REPLACED. THE LINK FOR THIS POLL IS: HTTP://CADILLACFORUMS.COM/FORUMS/SHOWTHREAD.PHP?P=305662&POSTED=1#POST305662. PLEASE CONTACT ME REGARDING ANY INFORMATION LEARNED. THANK YOU. *AK!

BOUGHT CAR IN AUGUST OF 2004, THIS IS THE FOURTH TIME CAR HAS BEEN PUT IN SHOP. CAR WOULD BE STILL RUNNING BUT "ENGINE REDUCE POWER DISPLAYED ON SCREEN", NO GAS WOULD GO TO PEDAL I WOULD HAVE TO COAST TO A SAFE LOCATION. DEALER CLAIMS IT IS THE THROTTLE BODY, EACH TIME THEY SAY THEY HAVE REPAIRED IT BUT THIS IS NUMBER 4. REPLACED A COMPUTER CHIP, FLUSHED OUT THROTTLE BODY COMPONENT, REPLACE CRAKED CRANK SHAFT CASE, HAVEN'T HEARD WHAT NOW THEY ARE REPLACING.

NOTICED A HIGH-PITCHED WHINE COMING FROM REAR AT 50000 MILES. STOPPED BY THE DEALERSHIP, THE SERVICE MANAGER DROVE THE VEHICLE AND STATED IT WAS THE TIRES CAUSING THE NOISE. CONTINUED TO DRIVE THE VEHICLE, SOUND BECAME MORE PRONOUNCED. A CHECK ENGINE LIGHT APPEARED, SO NEEDED TO SERVICE THE CAR. THIS REPAIR WAS UNRELATED TO THE WHINE, AN EMISSION CONTROL VALVE HAD FAILED. WHILE AT THE DEALERSHIP REQUESTED THEY CHECK, AGAIN, THE WHINE FROM THE REAR. WAS NOTIFIED THAT INDEED IT WAS THE DIFFERENTIAL THAT NEEDED REPLACING. HAVE NOT TAKEN POSSESSION OF THE VEHICLE, BUT AM CONCERNED ABOUT DRIVING IT NOW. MUCH CONCERNED ABOUT THE RELIABILITY OF THE VEHICLE.*AK

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
