So, let me see, after less than six months of ownership and less than 3,000 miles of driving, this is what has gone wrong with my new 2013 Porsche Cayenne Turbo: after bringing in my car for loud clanging noises when I backed the car up, they replaced my entire catalytic converter. Ten days later, due to different clanging noises, they replaced all of my muffler tips and replaced my electronic key fobs as the car was not recognizing them. Are you kidding me? I should have bought the Range Rover Sport for $40,000 less from the dealer less than a mile from my home. My neighbors who have bought Range Rovers have reported no such major repairs and certainly not to a brand new vehicle.
