Engine Clicking And Tapping Noises Problems of Porsche Cayenne

Car was bought as certified Porsche in Mar 2011 with 66k miles; current miles 165k miles; driven approx. For 100k miles in 6 years. Engine clicking noise was getting louder and louder. Told by mechanics that the "f" cyn. Walls are scored and engine needs to be replace. Checked on-line for this condition with other v-8 Porsche owners to find that it's very common. This seems like a design issue and safety wise ( no power, miss firing and stalling). A $100k new should not have a v-8 engine that has a design defect that is worth less at such low miles.

Upon taking the vehicle out of the driveway I started hearing a ticking sound coming from the engine, something like a lifter hitting the block. I pulled back in to my driveway and called a repair shop and scheduled an appointment. When meeting with the technician I was informed that the engine had a scored cylinder and that it is a common issue with the model and year. The only recourse to fix the issue would be to replace the engine. A replacement engine would cost $17 -35,000 - more than the vehicle is worth. If I were to replace it with a used engine, I would be destined for a repeat of the same issue. If this issue is such a common problem why has there not been a recall for these vehicles? I have contacted the manufacturer and was told that I would need to have a authorized service dealership make the diagnosis I have already been told, but there is not a authorized dealership within 500 miles of my location.
