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

IT CLUNKS, AND PRODUCES EXCESSIVE WHEEL-HOP THUS NOT ALLOWING THE POWER TO TRANSFER. THE WHOLE REAR END OF THE CAR FROM THE BUSHINGS TO THE REAR CRADLE TO THE HALF SHAFTS ARE TOO WEAK FOR THE CAR. OVER 1000'S OF CTS-V'S OF THE UNDER APPROX. 4,000 PRODUCED FROM 2004-2005 HAVE HAD MAJOR ISSUES. SERVICE CENTERS CLAIM EVERYTHING IS NORMAL. MY CAR IS CONTINUALLY IN THE SHOP. GM REFUSES TO PAY FOR THESE ITEM AND I HAVE A 6YR 100K WARRANTY. SERVICE CENTERS ARE NOT EQUIPPED TO DEAL WITH THIS CAR, AND GM FAILED TO ENGINEER IT PROPERLY. IN ADDITION ALL OF MY INTERIOR PARTS RATTLE WHEN I STEP ON IT, AND SOME CONTINUE TO RATTLE DURING DAILY DRIVING. THE PAINT QUALITY OF THE EXTERIOR IS THE WORST I HAVE TO SEE YET. THERE ARE WEIRD BLOTCHES ALL OVER THE PLACE AND ARE OBVIOUSLY DUE TO POOR PAINT APPLICATION AT THE FACTORY. I HAVE OWNED THE CAR FOR 3 MONTHS AND SO FAR HAVE HAD TO REPLACE THE RADIATOR, THE WHOLE NAV UNIT, THE REAR DIFFERENTIAL. AND ALREADY, THE NAV UNIT IS BEGINNING TO SHOW THE SAME INDICATIONS OF WHY IT GOT REPLACED IN THE FIRST PLACE, AND THE REAR DIFFERENTIAL IS STARTING TO MAKE NOISES AGAIN. ALSO, THE DUAL MASS FLYWHEEL PRODUCES LOTS OF NOISE. I HAVE HAD IT UP TO HERE WITH THIS VEHICLE. *JB

AFTER OWNING THE VEHICLE FOR A FEW MONTHS, WITH APPROXIMATELY 6,000 MILES ON THE CAR, I BEGAN TO EXPERIENCE AN EXTREME WHINING NOISE FROM THE REAR-END OF THE CAR. I TOOK THE CAR TO THE DEALERSHIP AND THEY SAID THE NOISE WAS NORMAL FOR MY VEHICLE. I CONTINUED DRIVING THE VEHICLE AND ABOUT 5 WEEKS AGO I TOOK MY CAR IN FOR EXCESSIVE NOISE COMING FROM THE REAR OF MY CAR. THE DEALERSHIP FOUND THAT THE REAR DIFFERENTIAL UNIT HAD EXCESSIVE PLAY AND NEEDED TO BE REPLACED UNDER WARRANTY. THIS CONCERNED ME SO I DID SOME RESEARCH. MY RESEARCH FOUND THAT MANY, MANY CTS-V OWNERS ARE HAVING THE EXACT SAME PROBLEM AND THAT MY PROBLEM WAS IN NO WAY ISOLATED. I ALSO FOUND THAT THE DIFFERENTIAL UNIT USED IN THE CTS-V IS UNDERRATED AND IS NOT DESIGNED TO HANDLE THE POWER PRODUCED BY THE ENGINE FROM THE FACTORY. I AM CONCERNED THAT A FAILURE IN THE NEAR FUTURE WILL CAUSE SERIOUS INJURY TO SOMEONE IF NO ACTION IS TAKEN. *JB

AGAIN, THE REAR DIFFERENTIAL WAS REPLACED AND THE REPAIR ORDER NOTED THAT IT WAS ALSO LEAKING DIFFERENTIAL FLUID. I CONTACTED SEVERAL OTHER OWNERS OF THE SAME TYPE OF CAR AND THEY HAVE THE EXACT SAME PROBLEM. I'M CONCERNED THAT THIS IS A RE-OCCURRING PROBLEM DUE TO A UNDER RATED DIFFERENTIAL. *JB
