2004 Cadillac CTS Powertrain & Transmission Problems

The output shaft flange for the transmission that mounts to the driveshaft coupler the flange starts to break away and then breaks . I can provide photos but the metal on the part is close the the end and if I did not find this problem by mistake the drive shaft would have came free

AT ABOUT 100K I NOTICED THE AXLE SEALS ON THE REAR DIFFERENTIAL IS LEAKING. THERE ARE RECALLS ON THIS BUT NOT BASED ON MY VIN NUMBER. WHEN I NOTICED THIS THE CAR WAS ON A LIFT IN THE AIR BEING INSPECTED BY A MECHANIC.

REAR PINION SEAL FAILED AND REAR AXLE LOCKED UP. LOST CONTROL AND WAS INVOLVED IN ACCIDENT. SHOCKED TO FIND OUT THERE IS A RECALL FOR 2005 AND NEWER CTS (NHTSA CAMPAIGN NUMBER: 07V589000, GM RECALL NO. 07204) BUT NOT MY 2004 WHICH HAS AN IDENTICAL REAR MAIN SEAL. THE PART NUMBER USED IN THE RECALL IS THE SAME TO REPAIR MY 2004. *TR

TL* THE CONTACT OWNS A 2004 CADILLAC CTS. THE CONTACT STATED THAT AFTER PARKING THE VEHICLE, IT REVERSED FOUR FEET BEFORE COMING TO A COMPLETE STOPPED. THE FAILURE RECURRED TWICE. THE VEHICLE WAS TAKEN TO THE DEALER FOR DIAGNOSIS. THE TECHNICIAN WAS UNABLE TO LOCATE THE FAILURE. THE VEHICLE HAS NOT BEEN REPAIRED. THE MANUFACTURER WAS NOT NOTIFIED OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 7,000.

WAS DRIVING DOWN THE ROAD AT 55 MPH AND ALL OF A SUDDEN WE LOST DRIVE POWER. THE RPM'S REVVED UP TO 4 BEFORE I COULD PULL OVER ON A BUSY ROAD JUMPING TWO LANES OF TRAFFIC WITH MY THREE KIDS IN THE CAR. IT WAS STORMING THE CAR WAS RUNNING BUT WOULD NOT ENGAGES IN GEAR. WHEN WE GOT OUT THERE WAS TRANSMISSION FLUID PORING AND SPRAYING OUT OF THE CAR WE QUICKLY KNEW TO TURN IT OFF AND CALL FOR HELP. WHEN WE GOT THE CAR HOME WE SAW THAT THE TRANSMISSION LINE CAME OFF THE RADIATOR. I HAVE SEEN SENSE THEN THAT THIS PROBLEM IS VERY COMMON AND MOST PEOPLES TRANSMISSION ARE SHOT AFTER THIS HAPPENS. WITCH IS A $5000 FIX. THERE WAS NO INDICATORS THAT THE PART WAS BAD OR THAT THE COOLANT PAN WAS LOOSE IN THE BOTTOM OF THE RADIATOR WHICH STRIPED OUT THE NUT ON THE LINE LEAVENING ME AND MY THREE KIDS STRANDED ON THE SIDE OF THE ROAD. CADILLAC KNEW THIS WAS A PROBLEM SO THEY PUT OUT A AFTER MARKET PART WITH A QUICK DISCONNECT NOT THE SCREW IN PART LIKE MY CAR HAD. I FOUND THAT OUT AFTER I CALLED AROUND TO HAVE MY CAR FIXED. *TR

TL* THE CONTACT OWNS A 2004 CADILLAC CTS. THE CONTACT STATED THAT WHILE TRAVELING 35 MPH, A HUMMING NOISE EMITTED FROM THE ENGINE COMPARTMENT. THE VEHICLE VIBRATED AND THE ENGINE LIGHT ILLUMINATED ON THE INSTRUMENT PANEL. THE CONTACT MENTIONED THAT AFTER THE SPEED INCREASED TO 60 MPH, THE VEHICLE NO LONGER VIBRATED. THE MANUFACTURER WAS NOT CONTACTED. THE VEHICLE WAS TAKEN TO AN INDEPENDENT MECHANIC WHO DIAGNOSED THAT THE TRANSMISSION NEEDED TO BE REPLACED. THE VEHICLE WAS NOT REPAIRED. THE FAILURE MILEAGE WAS 57,000 AND THE CURRENT MILEAGE WAS 57,565.

I HAVE HAD NUMEROUS PROBLEMS WITH MY 2004 CADILLAC CTS. THE MOST RECENT IS WITH MY REAR DIFFERENTIAL. THE LATEST PROBLEM WITH THE DIFFERENTIAL PROMPTED AN ONLINE SEARCH WITH THE RESULTS SHOWING THAT EACH OF THE PROBLEMS I HAVE HAD WITH MY CADILLAC CTS IS ONE THAT HAS HAPPENED WITH 1000'S OF OTHER 2004 CTS MODEL CADILLACS. *TR

WHILE DRIVING FOR BUSINESS THE REAR END STARTED MAKING A GROWLING NOISE AND THEN IT STARTED TO CUT IN AND OUT. STILL MAKES NOISE AND CUTS IN AND OUT MORE IN TURNS. *TT

I STOPPED AT A STOP SIGN, PUT VEHICLE INTO FIRST GEAR, BEGAN TO LET OFF OF CLUTCH, HEARD & FELT A VERY LOUD BANG. REAR DIFFERENTIAL EXPLODED. *TR

2004 CTS W/ 89160 MILES COMPLETE AND SUDDEN LOSS OF TRANS FLUID. HAD TOWED TO GM DEALER AND WAS ADVISED THAT THE TRANS LINES TO THE RADIATOR WERE "STRIPPED " AND BOTH NEEDED REPLACING. WE BOUGHT THE CAR NEW AND THIS AREA HAS NEVER BEEN SERVICED OR TOUCHED. DEALER THAT WORKED ON PROBLEM IS ST. *TR

REAR DIFFERENTIAL LEAKING - DRIVER SIDE AXEL SEAL WILL NEED TO BE REPLACED AGAIN. WAS REPLACED FOR SAME ISSUE AT ABOUT 6K MILES NOW SAME PROBLEM AT ABOUT 10K MILES, I SUSPECT THE CASE IS WARPING. *JB

1) I TOOK MY CAR IN ON 3/30 COMPLAINING OF A LEAKING REAR DIFFERENTIAL. I WAS INFORMED NOTHING WAS WRONG WITH THE VEHICLE. 4/20 I WAS DRIVING ON THE HIGHWAY AT NORMAL SPEEDS. I DOWN SHIFTED AND HEARD A LOUD BANG. THE ENGINE REVVED YET THE CAR WOULDN'T MOVE. THE REAR DIFFERENTIAL HAD QUITE LITERALLY EXPLODED. 2) THE HOUSING TO THE REAR DIFFERENTIAL SHATTERED CAUSING ONE OF THE BOLTS TO COME OUT AND THE REMAINDER OF THE HOUSING TO HANG AT AN ANGLE. THE INTERNALS OF THE DIFFERENTIAL LOOKED AS THOUGH A GRENADE HAD BEEN SET OFF IN THEM. THE PASSENGER SIDE REAR HALF SHAFT WAS HANGING OUT OF THE HOUSING. 3) I'M CURRENTLY LOCKED IN A FIGHT WITH MY LOCAL CADILLAC DEALERSHIP. THEY ARE TRYING TO REFUSE WARRANTY. *JB

SO ILL START OFF WITH ABOUT COMPLAINING TO THE DEALER ABOUT MY REAR END MAKING A MOANING WHINNING SOUND. I WENT IN MORE THAN ONCE TO TELL THEM ABOUT HOW IT KEEPS GETTING LOUDER AND THAT I KNOW SOMETHING IS NOT CORRECT. I AM CURRENTLY SELLING MY CAR AND WANT IT PERFECT FOR ANYONE WHO BUYS IT. THE CADILLAC DEALERSHIP KEEPS TELLING ME THAT ALL OF THIS IS NORMAL AND THEY DO NOTHING. SO LET ME TELL YOU A LITTLE BIT ABOUT HOW IT ALL STARTS. I WAS AT A RACEWAY ROAD COURSE PRACTICING DRIVING ONE OF MY RACE CARS FOR A RACE THAT I HAVE COMING UP. MY GIRLFRIEND WANTED TO GO AROUND THE TRACK A FEW TIMES TO SEE HOW IT FELT SO I TOOK HER FOR A LITTLE RIDE IN THE CADILLAC NOTHING MORE THAN DRIVING UP A WINDEY ROAD. WE PACK UP OUR STUFF AND I LEAVE WITH MY GIRLFRIEND TO MEET MY FOLKS FOR DINNER. I STARTED DRIVING UP A FREEWAY ON RAMP AND HIT A LITTLE BIT OF WATER AS I WAS ACCELERATING THEN GET A LITTLE BIT OF WHEEL HOP AND BOOM! MY CAR SUDDENLY STOPS IN FRONT OF A BIG RIG THAT WAS ON MY TAIL THE WHOLE TIME AND I BARELY HAVE TIME TO MOVE TO THE SIDE OF THE ROAD WITHOUT GETTING RAN OVER. I TRAILER MY CAR TO THE DEALERSHIP AND THEY TELL ME MY CAR WAS ABUSED! I KNEW ABOUT THE REAR ENDS AND DIDN'T WANT TO DEAL WITH THE CAR AND ALL ITS PROBLEMS AND THAT IS WHY I DIDN'T WANT TO RISK DEALING WITH IT. I FEEL THAT THIS IS A HUGE HAZARD THAT CADILLAC SEEMS TO JUST BE IGNORING. THEY NEED TO DO SOMETHING BEFORE SOMEONE GETS KILLED. I KEEP THINKING ABOUT IT AND HOW IT COULD HAVE BEEN A LOT WORSE FOR ME AND MY GIRLFRIEND. THE DEALERSHIP REFUSED TO FIX THIS PROBLEM BUT AT LEAST WE WALKED AWAY! NOW I AM SCARED FOR WHOMEVER I SELL THIS CAR TOO. SOMEONE FROM THIS WEBSITE NEEDS TO DO A GOOGLE ON ALL OF THE PROBLEMS WE ARE HAVING BECAUSE I DON'T THINK PEOPLE KNOW ABOUT THIS WEBSITE. THANKS GUYS, MICHAEL LEBARD. *NM

THE REAR DIFFERENTIAL ON MY CADILLAC CTS-V HAS FAILED TWICE IN THE 20,100 MILES THAT I HAVE DRIVEN IT. *JB

THE EVENTS LEADING UP TO THIS FAILURE WERE DAILY NORMAL DRIVING. FOR THE SECOND TIME IN TWO YEARS, THE REAR END OF MY CAR BEGAN TO EXHIBIT A WHINING SOUND WHEN ACCELERATING IN 4TH GEAR, AND THE SOUND BECAME PROGRESSIVELY LOUDER. THE DIFFERENTIAL ON MY CAR WAS REPLACED UNDER WARRANTY. *NM

THE REAR DIFFERENTIAL IN MY 2004 CADILLAC CTS-V HAD BEEN WHINING AND GRINDING FOR ABOUT 5500 MILES (STARTING WHEN THE CAR HAD 9000 MILES ON IT). THE DIFFERENTIAL FLUID HAD BEEN CHANGED THREE (3) TIMES IN 4000 MILES AND THE PROBLEM WAS NOT SOLVED. FINALLY, TOOK THE CAR TO THE DEALERSHIP WITH 14500 MILES AND CADILLAC AGREED TO CHANGE REPLACE THE DIFFERENTIAL WITH THE 2006 PART. *JB
