2005 CADILLAC CTS Power Train Problems

Transmission cooler line fittings have dissimilar metals causing the threads inside the radiator transcooler to strip and dump coolant into Transmission lines and on road along with what was the transmission fluid as well as steam rolling out blocking vision through my windshield going uphill on a dangerously busy road crossing.This is a well known manufacturing defect that has yet to be handled. This could have gotten me and my 3 year old son seriously hurt by sudden loss of power and slick roadways not being able to avoid or brake properly or even steer away from on coming collision. The dissimilar metals are aluminum nut with a mild steel washer backed by a stainless steel washer before it contacts the radiator. This car has 101k miles and has been babied it's entire life. And when I see the 4 brake lines are about to rust out after all the repairs that have already been done. This is just poor quality material and craftsmanship. Easily could have been avoided by simply using a different metal than mild steel between dissimilar metals.

THE VEHICLE IS EQUIPPED WITH A VERY WEAK REAR DIFFERENTIAL THAT WAS USED IN THE LESSER HORSEPOWER V6 AND WHEN TAKING OFF HARD THE CAR BEGINS TO WHEEL HOP AND DESTROYS THE REAR END THE VEHICLE WAS IN MOTION ON A CITY STREET THIS HAS OCCURRED TWICE IN LESS THEN A YEAR AND A HALF

THERE'S A VERY HARD JERKING COMING FROM SOME WHERE IN THE REAR AREA WHILE DRIVING. WHEN THIS HAPPENS THERE IS A LOST OF POWER. ALSO THE ENGINE OIL IS GOING SOME WHERE ,I KEEP HAVING TO PUT OIL IN IT , ABOUT TWO TO THREE QUARTS A WEEK. WHEN THE OIL GETS REAL LOW THE ENGINE SHAKES AND RUNS LIKE CRAP AND ACTS LIKE IT WANTS TO CUT OFF.

VEHICLE DEALER REFUSED TO PERFORM OPEN RECALLS. I REPLACED FRONT BRAKE HOSES MYSELF AT MY OWN COST. THEY STATED VERY HIGH MILEAGE 184000 MILES AND YOU DID NOT BUY THE CAR HERE.

I WAS TRAVELING APPROXIMATELY 65 MPH ON A 3 LANE HIGHWAY, WHILE MAINITANING A CONSTANT SPEED. SUDDENLY ALL POWER TO THE VEHICLE CUT OFF INCLUDING MY POWER STEERING AND BRAKING. IN A PANIC AS I AS COASTING I WAS FORTUNE ENOUGH TO WEAVE MY WAY ACROSS 2 LANES TO THE SIDE OF THE HIGHWAY AND ROLL TO A COMPLETE START. AFTER GATHERING MYSELF I TURNED THE IGNITION FROM THE RUN POSITION TO OFF. I LOOKED UP AND NOTICED THERE WAS SMOKE COMING OUT FROM UNDER THE HOOD. I JUMPED OUT, LIFTED THE HOOD, AND HEARD POPPING AND STEAM/SMOKE RISING UP FROM UNDERNEATH THE ENGINE BY THE FIREWALL. I PULLED THE OIL DIPSTICK AND I WAS ABOUT A QUART LOW, AND IT LOOKED NORMAL. I WAITED ABOUT 30 MIN AND CHECKED THE LEVEL AGAIN WITH THE SAME RESULT. I THEN TRIED TO START THE VEHICLE AND THERE WAS NOT RESPONSE AT ALL. I WAS UNABLE TO ROLL UP MY WINDOWS, AND THERE WAS NO POWER TO DISPLAY ANY INFORMATION ON DASH. WHEN MY WIFE ARRIVED I HOOKED UP JUMPER CABLES AND AFTER A WHILE I WAS ABLE TO TURN THE KEY FORWARD TO SEE THE INSTRUMENT PANEL. IT SAID MY BATTERY WAS AT THE CORRECT VOLTS, AND THERE WERE NO WARNING LIGHTS ON MY DASH. WHEN I TURNED THE IGNITION TO START. MY DASH FLICKERED RAPIDLY AND THERE WAS A CLICKING NOISE BUT THE ENGINE MADE NO SOUND AS IF IT WAS TRYING TO TURN OVER. SO I CALLED TOW TRUCK AND GOT TOWED TO MY HOUSE. THE VEHICLE WAS PURCHASED BY ME IN 09 WITH 32K MILES. IT HAD AN ISSUE WHERE IT WAS EATING UP TO 4 QUARTS OF OIL EVERY 1K-3K MILES. I HAD PURCHASE AN EXTENDED WARRANTY SO BYE 50K MILES THEY TORE APART ENGINE REPLACING PRETTY MUCH THE ENTIRE ENGINE. THE CAR CURRENTLY HAS LESS THEN 20K MILES SINCE WARRANTY REBUILD AND I AM AT A LOSS. I PUT A NEW BATTERY IN IT AND THAT HAS DONE NOTHING TO HELP. STILL JUST MAKES A STRANGE CLICKING NOISE. I HAVE NO IDEA WHAT TO DO NOW. IT IS A 2005 CTS 3.6L BASE AUTOMATIC TRANSMISSION

AFTER A ROUTINE OIL CHANGE AT BROGAN CADILLAC SERVICE IN TOTOWA, NJ, THE RECOMMENDED SERVICE (APPROX COST $1200) WAS THE REAR DIFF BUSHING WAS WORN AND THE REAR AXLE SEALS ARE LEAKING FLUID. AN INTERNET SEARCH UNCOVERED GM RECALL# 07204 FOR THIS MAKE AND MODEL THAT STATES "THE REAR AXLE PINION SEAL DOES NOT MEET ALL OF THE SPECIFICATIONS AND MAY EXPERIENCE A FLUID LEAK." WHEN I CALLED GM TO INQUIRE ABOUT THIS ISSUE I WAS TOLD THAT ALTHOUGH THERE WAS A RECALL FOR THIS PARTICULAR PROBLEM FOR CARS SOLD IN NEW JERSEY, IT WAS SPECIFIC TO CERTAIN VIN NUMBERS AND MY VEHICLE WAS NOT INCLUDED IN THIS GROUP. HOWEVER, THE CUSTOMER SERVICE AGENT MADE 2 FOLLOW UP CALLS TO ME AND THE SUPERVISOR OFFERED TO LOOK INTO MY SITUATION AND WOULD CONTACT ME ONCE SHE SPOKE WITH THE DEALER. PLEASE NOTE: FOR THE PAST TWO OR THREE YEARS THE SERVICE STABILITY SYSTEM ALERT WARNING INDICATOR LIGHT COMES ON EVERY TIME I START THE CAR AND INQUIRY AT THE DEALER LED TO ME HAVE THE STRUTS AND SHOCKS REPLACED BUT THE ALERT HAS NEVER RESET AND THE WARNING STILL COMES ON. ADDITIONALLY, THE INTERNET SEARCH UNCOVERED GM RECALL #09149 FOR THE SERVICE BRAKE SYSTEMS WHICH THE ALERT HAS BEEN ON FOR A FEW YEARS AS WELL. THE BRAKE SYSTEM HAS BEEN SERVICED SEVERAL TIMES TO REPLACE PADS AND ROTORS AND THE WARNING IS STILL PERSISTENT. I HAD BEEN TOLD IT WAS THE SENSOR THAT NEEDS TO BE REPLACE AND NOT TO WORRYABOUT IT. NOW I WONDER IF THIS TOO WAS "VIN SPECIFIC" AND DID NOT INCLUDE MY VEHICLE BUT LEAVES ME UNSAFELY AT RISK. I REALIZE THAT ENORMOUS EXPENSE IS CONNECTED TO RECALLS, HOWEVER MY SAFETY AS WELL AS THE SAFETY OF EVERYONE WHO PLACES CONFIDENCE IN CAR MANUFACTURERS TO DO WHAT IS RIGHT IS AT STAKE. WE DRIVE THESE VEHICLES AND DO NOT REALIZE THE GAMBLE WE TAKE WHEN SERIOUS ISSUES ARE NOT DEALT WITH CONSIDERATION FOR SAFETY FIRST! WILL YOU PLEASE SAVE MY LIFE AND GET GM TO FIX MY CAR?

I AM THE 2ND OWNER MY LOCAL DEALERSHIP IS CALLING MY PROBLEM "CATASTROPHIC FAILURE DUE TO CUSTOMER ABUSE". I OWN A 2005 CADILLAC CTS-V. MY ISSUE WAS ABOUT 10 OR 11 DAYS AGO. I LEFT WORK HEADED HOME AND ON THE ONRAMP TO HIGHWAY 240 IN ASHEVILLE, NC I HIT THIRD GEAR GOING ABOUT 45 OR 55 MPH AND MY REAR DIFFERENTIAL MADE A LOUD POP THE CAR JERKED AND THEN JUST BEGAN TO FREE ROLL. I THEN PROCEEDED TO CROSS THREE LANES OF TRAFFIC WITH NO MEANS OF ACCELERATION IN A HIGH TRAFFIC 60MPH ZONE IN ORDER TO GET TO A SAFE STOPPING ZONE. GM ROADSIDE SERVICE TOWED THE CAR TO THE DEALERSHIP I PURCHASED THE CAR AT. THE NEXT DAY WHEN I CAME TO SEE WHAT THEIR VERDICT WOULD BE THEY TOLD ME THAT WARRANTY WOULDN'T COVER IT AND I WOULD HAVE TO PAY OUT OF POCKET FOR A NEW DIFFERENTIAL AND LABOR AMOUNTING TO AROUND 2800 DOLLARS. I HAD CAME TO THE SAME DEALERSHIP THREE TIMES PRIOR TO THE INCIDENT AND REPORTED A POPPING IN THE REAR END WHEN SHIFTING BUT THERE WAS NO ACTION TAKEN AT ANY OF THE COMPLAINTS AND TO MY KNOWLEDGE NONE OF MY COMPLAINTS WERE FILED, THEY ONLY TOLD ME THAT IT WAS THE CLUTCH AND I WOULD JUST HAVE TO LEARN HOW TO PROPERLY SHIFT THE CAR. I THEN CALLED CADILLAC CUSTOMER SERVICE TO MAKE A COMPLAINT AND TO SEE IF THERE WAS ANY WAY TO HAVE THE WARRANTY COVER THE COST. CUSTOMER SERVICE CALLED ME BACK AND TOLD ME THAT THEY CONTACTED THE SERVICE MANAGER AT THE DEALERSHIP AND HE TOLD THEM IT APPEARED TO BE "CATASTROPHIC FAILURE DUE TO CUSTOMER ABUSE". THIS IS WHERE I AM STUCK AND THE CAR IS STILL AT THE DEALERSHIP IN THEIR HOLDING AREA WHERE IT WILL STAY UNTIL, A: SOMEHOW BY MIRACLE THEY SEND THE LOCAL CADILLAC REP. AND HE OKS THE WARRANTY REPAIR OR, B: I MAGICALLY COME UP WITH THE COST OF REPAIR.

THEY CHANGED THE REAR DIFFERENTIAL FINALLY AND STATED THAT THERE WAS COMPLETE FAILURE DUE TO LEAK OF FLUID. [SMCH FROM E-MAIL]

I HAVE HAD 3 REAR DIFFERENTIALS REPLACED IN THE TWO YEARS OF OWNERSHIP FOR MY 2005 CADILLAC CTS-V. THEY WERE EVALUATED BY MY DEALERSHIP TO BE FAULTY AND WERE REPLACED UNDER WARRANTY. CURRENTLY, MY 4TH DIFFERENTIAL IS NOT GIVING ME A PROBLEM BUT I AM CONFIDENT IT IS SIMPLY A MATTER OF TIME. *JB

- DEGRADATION OF THE REAR CARRIER ASSEMBLY (E.E. REAR DIFFERENTIAL). - REPLACEMENT OF REAR CARRIER ASSEMBLY 3 TIMES (ON 4TH DIFFERENTIAL BY 45K MILES) - NO CATASTROPHIC FAILURES, BUT ON ALL OCCASIONS CARRIER ASSEMBLY BECAME SO NOISY THAT IT COULD BE HEARD WITH THE WINDOWS DOWN AT SPEED WITH THE RADIO ON. HAD IT REPLACED BEFORE A FAILURE, AS THE CAR WAS UNDER WARRANTY. ON THE 3RD DIFFERENTIAL, THE PINION SEAL BEGAN TO LEAK ALSO. *JB

I HAVE A 2005 CADILLAC CTS-V MY FIRST ISSUE WAS BACK IN 05/05 8,200 MILES ON CAR WHILE DRIVING CAR WOULD NOT ALLOW ME TO SHIFT OR CHANGE GEARS THE CAR STALLED AND ROLLED TO A STOP. I CALLED FOR ROAD SERVICE 2 HOURS FROM HOME THEY TOWED CAR TO AN AREA DEALER WHO LATER CALLED TO INFORM ME THE REAR DIFFERENTIAL FAILED AND GM HAD REFUSED TO PAY FOR SERVICE. I HAD THE CAR TOWED TO MY LOCAL DEALER AT MY EXPENSE, AT MY DEALERS REQUEST. THEY INFORMED ME THAT GM SAID THE CAR HAD EXCESSIVE TIRE WEAR AND DAMAGE WAS CAUSED BY DRIVER ABUSE OR AGGRESSIVE DRIVING I WAS FORCED TO HIRE AN ATTORNEY AND PAY FOR A VEHICLE I COULDN'T DRIVE FOR SEVERAL MONTHS. LATE IN AUGUST 05 CADILLAC AGREED TO PAY FOR THE REPAIR. 01/07 27,000 MILES I WAS DRIVING THE CTS-V CHANGED GEARS FROM 2ND TO 3RD APPROX 30 MPH HEARD A CLUNK AND REAR END STARTED TO WHINE I PARKED THE CAR, CALLED ROAD SIDE SERVICE ,THEY TOWED THE CAR TO THE DEALER. CUSTOMER SERVICE REP CALLED A FEW DAYS LATER HE SAID THE REAR END HAS FAILED AGAIN AND NEEDS COMPLETE REPLACEMENT THE HANGAR BARING IS BENT, THE MAIN BOLT IS BROKE IN TWO PIECES AND IS RECOMMENDING A COMPLETE NEW REAR END HE ALSO SAID GM REFUSED TO PAY FOR SERVICE TO HIS SURPRISE. HERE WE GO AGAIN. MY LOCAL DEALER HAS THE CAR IT HAS NOT BEEN REPAIRED AS OF YET, SO YES THE OLD PARTS ARE AVAILABLE. THE CADILLAC CTS-V REAR DIFFERENTIAL IS WEAK AND MAY BREAK CAUSING THIS CAR TO SKID OR SUDDENLY STOP, CAUSING AN ACCIDENT, INJURY,OR DEATH. CADILLAC KNOWS OF PROBLEM AND HAS PROVIDED SOME CUSTOMERS WITH WARRANTY REPAIR, OFFERED 100,000 MILE EXTENDED WARRANTIES FOR OTHERS AND YET DENIED REPAIR FOR CUSTOMERS WITH SIMILAR PROBLEMS. THIS REAR DIFFERENTIAL IS UNDER RATED FOR THIS CARS HORSE POWER AND WAS DESIGNED FOR USE IN THE STANDARD CTS VERSION OF THIS CAR THE REAR TIRES HAVE ALSO BEEN A PROBLEM SHOWING EARLY SIGNS OF WEAR. I HAD TO REPLACE MY FIRST SET FRONT AND REAR AT 8,500 MILES, THESE TIRES ARE WORST RATED TIRE BY CONSUMERS AT WWW.TIRERACK.COM AND CADILLACFAQ.COM *JB

PURCHASED MY NEW 2005 CTS IN JAN. 2005. WONDERFUL CAR. WINE BEGAN IN THE REAR END OF THE CAR ALMOST IMMEDIATELY. THE DEALER REPLACED THE PINION GEAR, SEALS ETC . NOISE PERSISTED. HAD THE DEALER CHECK FOR THE NOISE AGAIN ABOUT MAY .'05 , THEY COULD NOT HEAR ANY NOISE. IT CONTINUES TO GET LOUDER ESPECIALLY UNDER LIGHT ACCELERATION IN THE 40 TO 50 KILOMETER RANGE. IT IS UNNERVING AND I FEAR IT IS GOING TO FAIL . NOT A NICE THING FOR SUCH A GREAT CAR !THE DEALER IS LESS THAN INTERESTED IN RESOLVING THE MATTER. *JB

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

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

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

I HAVE A 2005 CADILLAC CTS-V WITH 17800 MILES. IT HAS DEVELOPED A WHINE IN THE REAR DIFFERENTIAL. UPON INVESTIGATING FURTHER, I FOUND THIS HAS NOT BEEN UNUSUAL FOR THIS MODEL. (GM HAS USED THE SAME DIFFERENTIAL IN THIS CAR AS THEY PUT IN THE BASE CTS MODEL, WHICH HAS SIGNIFICANTLY LESS TORQUE) UPON TAKING THE CAR TO THE GM DEALER, THEY SAID THEY WOULD HAVE TO REPLACE THE DIFFERENTIAL, BUT WOULD HAVE TO AWAIT PARTS TO DO SO. THEY ARE TO CALL ME WHEN THEY GET THE PARTS IN STOCK. THEY ALSO SAID THE CLUTCH HAS BEEN UPDATED AND HAVE ORDERED A NEW CLUTCH ALSO. *JB

I WAS SIMPLY DRIVING "NORMALLY" AND A "CLUNK" WAS HEARD FROM THE REAR OF THE CAR. THE VEHICLE WAS NOT DRIVABLE. IT HAD TO BE PUT ON A FLAT BED TRUCK AND TAKEN TO THE DEALER. THE RIGHT HAND HALF SHAFT BROKE IT TWO PIECES AND DESTROYED THE DIFFERENTIAL IN THE PROCESS. *NM

WITH ONLY ABOUT 3370 MILES ON A BRAND NEW CAR, MY REAR DIFFERENTIAL INTERNALS WERE DESTROYED AND THE HOUSING CRACKED DUE TO THE FOLLOWING 2 REASONS: 1. EXCESSIVE WHEEL HOP DUE TO A POORLY DESIGNED REAR SUSPENSION 2. THE DIFFERENTIAL THAT COMES STOCK IN EVERY 2004-2005 CTS-V CADILLAC IS NOT RATED TO HANDLE AS MUCH HORSEPOWER AND TORQUE AS THE CAR PUTS OUT. GM CUT CORNERS AND PUT IN A DIFFERENTIAL THAT WAS MEANT FOR THEIR V6 BASE MODEL CTS THAT MAKES ABOUT HALF THE POWER. WHEN THE REAR DIFFERENTIAL BLEW UP, IT ALSO DESTROYED MY DRIVESHAFT. I NOTICED THE DIFFERENTIAL OVER TIME STARTED TO WHINE AND CLUNK MORE AND MORE AND BECOME LOUDER AND LOUDER UNTIL ALL OF A SUDDEN WHILE DRIVING I HEARD A LOUD BOOM AND A BUNCH OF CLUNKING AND METAL GRINDING. THE CAR WAS IMMEDIATELY UNDRIVEABLE. MY DEALERSHIP REPLACED MY DRIVESHAFT AND THE DIFFERENTIAL WITH A 2006 CTS-V DIFFERENTIAL WHICH IS A BEEFIER PIECE. I HAVE 2500 MILES ON THE NEW DIFFERENTIAL WHICH IS ALREADY STARTING TO WHINE AND CLUNK. WHEEL HOP IS STILL ATROCIOUS AND IT IS ONLY A MATTER OF TIME BEFORE THIS DIFFERENTIAL BREAKS AS WELL. MY DEALERSHIP DENIED KNOWLEDGE OF ANY ISSUES WITH CTS-V REAR ENDS, AND TRIED TO PLACE THE BLAME ON ME BY STATING THAT MY REAR TIRES WERE VERY WORN FOR ONLY 3370 MILES, SO I MUST HAVE BEEN ABUSING THAT CAR. THAT IS NOT THE CASE, AND THESE TIRES ARE NOTORIOUS FOR HAVING THE WORST TREAD WEAR OF ANY TIRE ON THE MARKET, AND EVERY CTS-V OWNER COMPLAINS ABOUT HOW LONG THEY LAST. IN FACT, CONSUMERS GAVE THE TIRES ON THIS CAR THE WORST RATING OF ANY TIRE LISTED ON "THE TIRE RACK." SEE HERE: HTTP://WWW.TIRERACK.COM/TIRES/TIRES.JSP?TIREMAKE=GOODYEAR&TIREMODEL=EAGLE+F1+SUPERCAR+EMT CONSUMERS RATE THE TIRE WEAR AS A 2.6/10. WHAT A JOKE, AND CADILLAC DEALERSHIPS PLACE THE BLAME FOR THE TIRE WEAR ON ME THE OWNER. *NM

Mileage: 5,375

THE DIFFERENTIAL IN MY CAR HAS STARTED TO WHINE AFTER ~11K MILES DESPITE, PERHAPS, THE LEAST ABUSIVE DRIVING THAT IS REASONABLY POSSIBLE, ESPECIALLY CONSIDERING THAT THIS CAR IS A CTS-V. TO SAY I AM DISAPPOINTED WOULD BE AN UNDERSTATEMENT. AFTER A LITTLE BIT OF INVESTIGATION, IT APPEARS THAT GM HAS USED AN UNDER-ENGINEERED PART FOR ITS DIFFERENTIAL FOR REASONS I'M NOT REAL CERTAIN OF. MULTIPLE FAILURES ARE BEING REPORTED ALL ACROSS THE COUNTRY, MANY WITH SIMILAR DRIVING HABITS THAT I HAVE. THE CTS-V DIFFERENTIAL IS A LIMITED SLIP 3.73 APPLICATION AND REQUIRES ~ 7% FRICTION MODIFIED OIL. SUCH FLUID WAS CHANGED SEVERAL THOUSAND MILES AGO AS A PRECAUTIONARY MEASURE AND THE PROPER OIL WAS ADDED. I PLAN ON TAKING MY CAR IN FOR EVALUATION/SERVICE IN THE NEAR FUTURE, BUT I BELIEVE THAT GMS DECISION TO INSTALL A CLEARLY KNOWN "BAD" PART IS WHOLLY EGREGIOUS. *JB

TOOK DELIVERY MAY, 2005. IN LESS THAN THREE MONTHS, WITH APPROXIMATELY 1,500 MILES, DIFFERENTIAL BEGAN TO WHINE AT SPEEDS BETWEEN 45 AND 50 MPH, ONCE UP TO NORMAL OPERATING TEMPERATURE. VEHICLE CURRENTLY HAS ~5,200 MILES. DIFFERENTIAL NOW WHINES BETWEEN 40 AND 55 MPH. THERE SEEMS TO BE A CONSENSUS AMONG MANY CTS OWNERS THAT THIS CONDITION IS A PRECURSOR TO COMPLETE, AND SOMETIMES SUDDEN, DIFFERENTIAL FAILURE. *JB

WHEN DRIVING IN RAIN / POOR WEATHER, THE CAR DURING TAKE-OFF VIOLENTLY SHAKES WHEN THE REAR WHEELS SPIN. THIS SHAKING HAS THROWN OFF MY REAR ALIGNMENT, AIDED IN PREMATURE TIRE WEAR, AND MAY HAVE CAUSED SIGNIFICANT REAR-END DAMAGE. *JB

ON AUG. 26, 2005 OUR THREE MONTH OLD CADILLAC CTS'S TRANSMISSION WOULD NOT SHIFT OUT OF FIRST GEAR AFTER GOING THROUGH A BUSY TOLL BOOTH. CAR HAD TO BE TOWED TO DEALER FOR 8 DAY REPAIR OF COMPUTER AND REPLACEMENT OF TRANSMISSION. FEW DAYS LATER CAR HAD TO GO BACK TO DEALER DUE TO TRANSMISSION NOT SHIFTING PROPERLY, OUT OF COMMISSION FOR DAYS AGAIN. AFTER PICKING VEHICLE UP, CAR WOULD NOT START IN GARAGE AND HAD TO BE TOWED TO DEALERSHIP AGAIN, PICKED UP CAR A COUPLE OF DAYS LATER, NEXT DAY WOULD NOT START AGAIN AND HAD TO BE TOWED. AT DEALERSHIP FOR 6 MORE DAYS. WHEN PICKED UP DEALERSHIP REFUSED TO GIVE US A SERVICE TICKET SHOWING THE PROBLEM AND WHAT THEY DID. SERVICE MANAGER STATED THAT HE WOULD NOT GIVE US "AMMUNITION" TO GIVE TO A LEMON LAW ATTORNEY.
