Power Train Driveline Problems of Cadillac CTS

The contact owns a 2008 Cadillac Cts. While driving 45 mph, the engine stalled without warning. The vehicle was towed to an independent mechanic where it was diagnosed that there were cracks in the bearing on the drive train, which needed to be replaced. The vehicle was repaired, but the failure recurred. The vehicle was taken back to the independent mechanic where it was still being diagnosed. The local dealer (alaska sales and service anchorage, 1300 e 5th avenue, anchorage, ak 99501) was contacted and informed the contact that the vehicle was not included in any recall. The manufacturer was notified of the failure and the contact filed a complaint. The failure mileage was approximately 86,000.

I purchased a new 2011 Cadillac Cts coupe. It continuously makes a groaning sound which appears to be coming from the rear part of the drive train. The dealer changed the differential fluid to correct the problem. However, the problem remains. I believe this sound is produced by a defective component in the drive train (differential, bearings etc. ), which will ultimately lead to a component failure that can cause a serious accident.

2009 Cadillac Cts has serious vibration at highway speed, after several attempts to resolve, changing the left front and the right rear tire, the dealer claims the car operates as designed, I see other complaints on consumer affairs website of the exact same issue. I have asked the service manager of the dealer to ride with me in the car. He failed to do so, and didn't show up for two appointments at his dealership to drive the car. The vibration was present when I test drove the car the owner of the dealerships son told me the vibration existed in many cars because of the tires getting flat spots. He assured me it would go away in 200 miles or so. 10,000 miles later the vibration still present. Since the vibration is worst between 64 or 75 miles an hour, and causes the steering wheel to shank the potential for a serious accident exist anytime the cars are driven on the highway.

Vibration in drive between 45mph and 60mph.

2009 Cadillac Cts 3. 6 direct inject engine. Starting at 700 miles vehicle started shuddering between 40-75 m. P. H. Per gm they are aware of the design flaw but there is currently no fix for this engineering issue.

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.

2004 Cadillac Cts. The car has made a loud noise in the differential since purchased. The differential was replaced however, the noise and jerking of rear wheels continues. I have returned to the dealer several times only to be told there is nothing wrong with the vehicle. I have replaced the tires three times because the dealer said they were the source of the noise and jerking, but the condition still exists. I have checked the internet and information listed reveals the Cadillac Cts has a major defect in the drive train however gm has not acknowledged.

Rear differential whine on my 2003 Cadillac Cts. The slightest pressure under light acceleration causes the whine. Dealers are useless.
