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.

Manual transmission will not shift into gear has caused many near accidents. GM claims that this is normal and refuses to fix this. Many people report this issue and GM has not yet addressed this on the Cadillac Cts-V. it is a very dangerous condition when I cannot shift or get into gear.
