2005 CADILLAC CTS Complaints

2005 CTS V . . . NOTICED HOWLING WHINING NOISE COMING FROM REAR END. CADILLAC HAS REPLACED TWO REAR DIFFERENTIALS IN MY CAR AND ATTEMPTED TO FIX THE WHINING NOISE THREE OTHER TIME AND I STILL HAVE THE NOISE COMING FROM THE REAR END. MY CAR ONLY HAS 12,000 MILES AND NEEDS A THIRD REAR DIFFERENTIAL.

THE DIFFERENTIAL ASSEMBLY IN MY 2005 CADILLAC CTS-V WAS WHINING AFTER ONLY 5,000 MILES AND HAD TO BE REPLACED. *NM

DT*: THE CONTACT STATED WHILE DRIVING VARIOUS SPEEDS, THERE WAS A REFLECTION OF THE SUN ON THE WINDSHIELD FROM THE DASHBOARD. THIS ONLY OCCURRED WHILE FACING THE SUN DIRECTLY. THE VEHICLE WAS TAKEN TO THE SERVICE DEALER WHO RECOMMENDED THAT THE MANUFACTURER BE CONTACTED. THE MANUFACTURER WAS NOT NOTIFIED.

SEVERAL REAR END DIFFERENTIAL FAILURES. 1 AT 4000 MILES, THE SECOND AT 8000 MILES. AND THE THIRD IS LOUD AND MAKES NOISES FROM THE DAY I GOT IT BACK. GM TRIED TO VOID AND NOT COVER THE REAR END SO I HAD TO TAKE IT TO ANOTHER STATE FOR THEM TO FIX IT FOR ME. THEY JUST START OUT QUIET AND THEN GET LOUDER AND LOUDER AND LOUDER. THE LAST ONE DIED WITH MY FAMILY IN THE VEHICLE AT 40 MPH DURRING REGULAR DRIVING. REAR LOCKED UP THEN BROKE UP IN HALF. IT KILLED THE DRIVESHAFT AND SEVERAL OTHER PARTS WHEN IT LOCKED UP. I HAVE HAD 20+ GM CARS IN MY LIFETIME AND THIS ONE IS THE WORST BUILT REAR END EVER. IF I TRIED, I BET I COULD KILL IT IN ONE FULL THROTTLE LAUNCH. BUT, OF COARSE WONT TRY THAT CAUSE IT WILL BREAK.... ALSO, NEEDED A WHEEL ALIGNMENT, CLUTCH UPDATE, AND SEVERAL OTHER THINGS DONE. THE RADIO ACTS FUNNY AND PAINT ON ONE BUTTON IS COMMING OFF, AND MY HEAD LINER LIGHTS DONT WORK. ALSO I HAVE HAD TO REPLACE ALL 4 TIRES 2 TIMES ALREADY WITH FACTORY REPLACEMENTS AND I ONLY HAVE 10,000 MILES ON MINE???

DT*: THE CONTACT STATED THERE ARE SEVERAL THINGS WRONG WITH THE VEHICLE. THE CHECK COOLANT LIGHT AND THE CHECK ENGINE LIGHT ILLUMINATED ON THE DASHBOARD. THE DEALERSHIP DETERMINED THE RADIATOR WAS DAMAGE AND ATTEMPTED TO REPAIR THE RADIATOR FOUR TIMES. THE FIRST THREE REPAIRS PERFORMED BY THE DEALER IN AN ATTEMPT TO REPAIR THE RADIATOR WERE UNAVAILABLE. THE FOURTH TIME, THE DEALERSHIP DETERMINED THE PROBLEM WAS WITH THE WATER PUMP AND THE WATER PUMP WAS REPLACED. THE FUEL PUMP WAS ALSO FOUND TO BE DEFECTIVE AND WAS REPLACED. THE CHECK ENGINE LIGHT ILLUMINATED ON THE DASHBOARD PRIOR TO THE FUEL PUMP PROBLEMS. THE DRIVE SHAFT WAS DEFECTIVE CAUSING THE VEHICLE TO BECOME INOPERATIVE. THE CRS LIGHT ILLUMINATED IN THE VEHICLE. THERE WAS AN UNKNOWN PART REPLACED TO REPAIR THE CRS LIGHT. THE DRIVER'S POWER WINDOW WORKED INTERMITTENTLY MAKING A GRINDING NOISE AND THE DEALER REPAIRED THE WINDOW. THE WIRING WAS IN BACKWARDS ON THE PASSENGER SEAT CAUSING ONLY HALF OF THE SEAT TO MOVE. THE DEALERSHIP CORRECTED THE WIRING TO REPAIR THE SEAT.

CTS-V REAR DIFFERENTIAL WHINNING AT 35-40 MPH GM DID REPLACE IT. I HAD A 2003 CTS AND THE REAR DIFFERENTIAL LOCKED UP WHILE DRIVING 35 MPH AND SKIDDED ABOUT 20 FEET. GM REPLACED IT 3 TIMES AND FINALLY BOUGHT THE CAR BACK. ONE YEAR LATER WE BOUGHT THE 2005 CTS-V AND ITS DOING THE SAME THING, GM NEEDS TO FIGURE THIS OUT BEFORE SOMEONE DIES.... *NM

DIFFERENTIAL BEGAN WHINING AT 500 MILES. WAS TOLD THE NOISE WAS NORMAL BY THE CADILLAC DEALER. REAR DIFFERENTIAL FAILED AT 7500 MILES WITH THE DEALER INFORMING ME I HAD ABUSED THE CAR. *JB

REAR DIFFERENTIAL MAKES WHINING NOISE WHICH IS GETTING PROGRESSIVELY WORSE. CAR ONLY HAS 4,000 MILES. *JB

1-WHINE IN REAR END BETWEEN 44 AND 47 MPH 2-NOISE GOT LOUDER AS TIME WENT ON (AT 6700 MILES) 3-REAR END WAS REPLACED. *JB

I HAVE A 2005 CADILLAC CTSV WITH A FAULTY REAR UNDER-ENGINEERED REAR CARRIER UNIT THAT SUPPORTS THE REAR DIFFERENTIAL. IT IS LEAKING. CADILLAC HAS REPLACED THESE UNITS WITH THE SAME FAULTY UNDER-ENGINEERED UNITS MANUFACTURED BY GETRAG WITH 2006 UNITS. THIS SOLUTION HAS BEEN NOTHING MORE THAN A BAND-AID AND THE RESULT OF THE LEAKING IS FAULTY ENGINEERING AS DETERMINED BY SEVERAL HIGHLY RESPECTED ENGINEERING COMPANIES SUCH AS LINGENFELTER AND KATECH THAT GM DOES THERE ACTUAL OUTSOURCING TO. I AM VERY CONCERNED TO DRIVE THIS VEHICLE OUT OF FEAR THAT THE REAR END WILL FAIL AND CAUSE ME TO LOSE CONTROL OF THE VEHICLE AND CAUSE PROPERTY DAMAGE AND POSSIBLE FATAL BODILY INJURY. RATHER THAN CADILLAC ISSUING A RECALL TO REPLACE THIS UNIT WITH A PROPERLY ENGINEERED UNIT TO SUPPORT THE REAR WHEEL TORQUE THAT IS GENERATED BY THIS VEHICLE; THEY HAVE INSTEAD HID BEHIND A TECHNICAL SERVICE BULLETIN AND HANDLE THESE CASES ON A CASE BY CASE BASIS. I REMAIN HOPEFUL THAT YOU WILL TAKE ACTION BEFORE WE ARE DEALING WITH ANOTHER FIRESTONE TIRE ISSUE AS CADILLAC WAS MADE AWARE BY GETRAG THAT THIS REAR CARRIER DIFFERENTIAL WAS NOT "UP TO PAR" WITH THE ENGINE THAT THEY INSTALLED IN THE 2004 AND 2005 CADILLAC CTSV. *JB
