I bought my 2011 Cadillac Cts-v brand new on 04-12-11 ,my sealed rear end went out at 33,453 miles which I was out of warranty by 9 days so you guys made me pay $4690 for a �new rear end that had updated parts that failed and I wouldn't have this problem ever again . . . . . Well here I am at 54,569 miles and I need another new rear ended replaced me and the dealer both agreed . Now this time since I had it replaced at 33,000 miles now 18,000 1/2 miles later I need another new rear end there's recalls on all your other Ctsv models except for 2011 through 13 and they're all having the same problems with their sealed rear ends in the Ctsv's and the sports models like I said I paid $100,000 for this car brand new nine years ago I put an average of 4500 miles on it every year my wife drives it 98% of the time and she doesn't drive it fast or aggressive at all there's a really extreme problem with your sealed electronica rear ends and axle shafts I reported this to the safety centers and there's currently 4000 cars experiencing the same problem as mine and with the 14 and 15 models there's 2800 people with the same problem in the same rear end just different years please makeand replace my rear end at no cost as it's not my fault your parts fail. . . .

The way this happened again for the second time as I was driving in motion around cloverleaf about 20 miles an hour when all of a sudden it sounded like I was dragging garbage cans behind my car as to then I pulled over and put my hazards on and got out and looked behind my car to see nothing when I put it in drive again the car would not move and you just heard the rear and gears and pins spinning without making the car move extremely loud and dangerous my wife could� have been hurt if the rear end locked redacted to protect personally identifiable information pursuant to the freedom of information act (foia), 5 u.
