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.
2004 Cadillac CTS transmission complaints
Page 3 of 3: complaints 41 to 52 of 52, newest first, as owners wrote them.
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.
I purchased the car new on 1/08/05. The car started to make a howling noise after several thousand miles, gm tech's indicated that it was coming from the rear differential. The original rear differential was replaced at 3220 (7/1/05) miles due to internal failure of differential assembly. The howling noise occurred again at 5.565 ( 12/08/05) miles. Again, the rear differential was replaced and the repair order noted that it was also leaking differential fluid. I contacted several other owners of the same type of car and they have the exact same problem. I'm concerned that this is a re-occurring problem due to a under rated differential.
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.
Premature rear end differential failure.
Rear end differential assembly underrated for vehicle. The differential whined up until failure. The differential was replaced under warranty.
Wheel hop or axle tramp caused the rear to lose traction and the stability track and traction control failed to correct the problem. The axle tramp is a severe banging of the rear when there throttle is applied to the car. The rear spun and caused the car to hit a guard wall.
Rear differential failure/half driveshaft failure. Rear differential case fracture dand broke in half shafts.
2004 cadillac cts having problems with rear differential.*mr the rear differential has been replaced twice. The manufacturerindicated that the loud humming noise coming from the rear diffeential was normal.
This vehicle exibits excessive wheel hop, when under har accleration, the rear suspension carriage assembly hit the frame. The wheels jump up and down violently. Some cars have broken axles or damaged the rear differential. This could also cause loss of control.
Rear differential whine from 45 MPH after vehicle has driven at least 5 miles.
Have a noise in rear-end when accelerating up to speeds. When letting up on accerlator noise quits, but as soon as I give it gas it hums( like) very loud. Have had two cadillac dealers check it and told not to worry about it nothing is wrong and that , that' is the characteristic of the 2004 cts. This is hard for me to believe since I have had 8 cadillac over the years and have never had a problem of this nature.
