2004 Cadillac CTS Owner Comments

problem #3

Nov 212011

CTS 6-cyl

  • 93,000 miles


Noticed brown liquid leaking from the front driver wheel area. Had vehicle towed to GM dealer where they discovered a coolant line failure which created leaking of transmission fluid into radiator and coolant into transmission. Both transmission and radiator need replacing, car is unable to be driven. This was determined by the dealer and Cadillac to be a failure of the part, unable to be prevented and unable to detect. Consumer was not at all responsible for damage. Total estimated cost $4,900. Contacted GM where they offered to "split" the cost 50/50, myself reliable for the $2400. Although Cadillac took responsibility for the failure, I am responsible for the cost of repair.

The contact owns a 2004 Cadillac Cts. While driving approximately 15-20 mph the transmission cooling line broke off from the radiator and the fluid spilled out of the vehicle. He stated the vehicle stalled, there was fluid on the ground and inside of the vehicle. The vehicle was towed to an authorized dealer. The dealer replaced the radiator assembly and refilled the transmission fluid. The failure mileage was 61,971 and the current mileage was 62,100. Updated 01/04/11.

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.
