I have a 2005 Cadillac Cts-V my first issue was back in 05/05 8,200 miles on car while driving car would not allow me to shift or change gears the car stalled and rolled to a stop. I called for road service 2 hours from home they towed car to an area dealer who later called to inform me the rear differential failed and GM had refused to pay for service. I had the car towed to my local dealer at my expense, at my dealers request. They informed me that GM said the car had excessive tire wear and damage was caused by driver abuse or aggressive driving I was forced to hire an attorney and pay for a vehicle I couldn't drive for several months. Late in August 05 Cadillac agreed to pay for the repair. 01/07 27,000 miles I was driving the Cts-V changed gears from 2nd to 3rd approx 30 mph heard a clunk and rear end started to whine I parked the car, called road side service, they towed the car to the dealer. Customer service rep called a few days later he said the rear end has failed again and needs complete replacement the hangar baring is bent, the main bolt is broke in two pieces and is recommending a complete new rear end he also said GM refused to pay for service to his surprise. Here we go again. My local dealer has the car it has not been repaired as of yet, so yes the old parts are available. The Cadillac Cts-V rear differential is weak and may break causing this car to skid or suddenly stop, causing an accident, injury, or death. Cadillac knows of problem and has provided some customers with warranty repair, offered 100,000 mile extended warranties for others and yet denied repair for customers with similar problems. This rear differential is under rated for this cars horse power and was designed for use in the standard Cts version of this car the rear tires have also been a problem showing early signs of wear. I had to replace my first set front and rear at 8,500 miles, these tires are worst rated tire by consumers at www.tirerack.com and cadillacfaq.com
