| 10/09/2006 | 8059 | 1 | 10/20/2003 |
| 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 | |||

| 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 | |||

| 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 | |||
