2005 Cadillac CTS Owner Comments

A D V E R T I S E M E N T S

I own a 2005 Cadillac Cts with a 3.7 liter engine, and automatic transmission. I am the second owner, and purchased this vehicle when it had 55,978 miles on it. After driving the car for less then 2 years, it developed a noise coming from the back (rear end). I brought the car to my local Cadillac dealer. After a road test and inspection, the dealer determined that the problem was the rear differential, and it would need to be replaced at a cost of about $1700. I've owned many used cars over the past 30 years, some with over 100,000 miles on them, and I've never, never needed a new rear differential on any vehicle that I've ever owned! I understand that this is a common problem with this model. The dealer stated that the seals were good, and that all of the fluids were at the correct levels in the differential, and that the earlier Cts models had experienced problems with differentials, but that the problem was rectified with the 2005 model. Apparently it would seem that there are also problems with the 2005 model differential as well!

I own a 2005 Cadillac Cts-V I currently have 33K miles on my vehicle I have suffered through three catastrophic rear differential failures, the half shaft was also completely severed from the hub, possible due to a rear differential failure and main bolt failure from a prior repair to rear diff 3000 miles prior.GM has refused service warranty repair every time stating damage must be caused by driver abuse now $9000+ spent in repairs I again have found a rear diff. Seal leak and humming from rear end it seams as though I will be once again forced to fix this rear end at my expense approx $3200 again for the forth time with no option for an improved part or compensation for repair or loss of vehicle this car has been in the shop several times for months each time and the last time was over 5 months, oddly I discovered after calling several dealers about warranty help that no repairs or service completed on my vehicle shows up on any of the dealers service records for my vehicle except for a radio replacement and a clutch repair at 50 miles that occurred before I bought the vehicle. I have the rear differential from the second replacement and pictures of the half shafts. I hope that all should be made aware of possible dangers with this vehicle. It is possible if driven at speed a broken half shaft or axle could catapult the car or a wheel could separate injuring driver passengers and others on the roadway. This car is unsafe to drive. The rear differential and axle is faulty and someone is bound to get hurt seriously it is only a matter of time. I have complete records for repairs made and all expenses to date I want to sell the car but do not want to feel responsible for putting someone else in danger so selling the car private party is out. I have tried to sell the car back to the dealer but there offers have been grossly under value and payoff.

Purchased my new 2005 Cts in Jan. 2005. Wonderful car. Wine began in the rear end of the car almost immediately. The dealer replaced the pinion gear, seals etc. Noise persisted. Had the dealer check for the noise again about May.'05, they could not hear any noise. It continues to get louder especially under light acceleration in the 40 to 50 kilometer range. It is unnerving and I fear it is going to fail. Not a nice thing for such a great car !the dealer is less than interested in resolving the matter.

: the contact stated there are several things wrong with the vehicle. The check coolant light and the check engine light illuminated on the dashboard. The dealership determined the radiator was damage and attempted to repair the radiator four times. The first three repairs performed by the dealer in an attempt to repair the radiator were unavailable. The fourth time, the dealership determined the problem was with the water pump and the water pump was replaced. The fuel pump was also found to be defective and was replaced. The check engine light illuminated on the dashboard prior to the fuel pump problems. The drive shaft was defective causing the vehicle to become inoperative. The crs light illuminated in the vehicle. There was an unknown part replaced to repair the crs light. The driver's power window worked intermittently making a grinding noise and the dealer repaired the window. The wiring was in backwards on the passenger seat causing only half of the seat to move. The dealership corrected the wiring to repair the seat.
