 Upon completion of an interstate highway trip at highway speeds, i pulled into my driveway and came to an involuntary dead stop with a loud noise with the rh front end resting on the wheel. the suspension on the ground. the nut retaining the lower ball joint was missing. the rh sides of front end collapsed on r front wheel.. 2004 cadillac cts. earlier models had factory recall for same loose nut not this model. front end collapsing on front wheel at high speed is guaranteed catastrophe. if a nut is relied on to retain ball joint, that nut must be positively prevented from loosening by hole thru both nut and bolt, with cotter pin through holes. no such basic safety in evidence. design flaw catalytic cts 2004 and earlier modelsa also suspected. used to be loose lips sink ships - now - loose nuts kill people. bad bad bad. *nm
 Dt*: the contact stated while pulling into the driveway under normal road conditions at 10 mph, the front end of the vehicle collapsed. there was no prior warning before the incident occurred. the vehicle was towed to the dealer who determined the cause of the problem was due to the nut holding the bolt of the lower front ball joints was missing. the vehicle was repaired and no further problems occurred. the contact wrote the manufacturer a letter pertaining to the problem that occurred, and had not received a reply as of yet. *nm updated 10/30/06. *jb
 Failure of a second rear differential i was on the highway doing 55 mph in the center lane when the rear went. the car shut down forcing me to pull to the right in traffic without power. the car had to be towed as it would no longer move. *jb
 I own a 2004 cadillac cts-v. 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
 While driving 40 mph the rear end locked. as a result, the rear end began spinning out of control. *ak the vehicle was taken tot he dealer who replaced the rear because of noise. less than three miles from the dealer the vehicle the consumer heard noise and the rear end locked. as a result the vehicle did three 360 degree turns and finally came to rest in a truck stop parking lot. took car back to dealer and found out that the rear end was out of line from the time of purchased. the tires have been rotated on 2 occasions. this is the third trip back to the dealer for rear end noise. *bf *nm
 Under power the rear suspension rattles up against the floor. it sounds like its falling apart which prompts you to stab the brakes upon hearing it. *jb
 Rear differential of my 2004 cadillac ctsv is too weak. 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
