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.

Dt: the contact owns a 2004 porsche cayenne s. While driving up a hill at slow speeds the vehicle will feel as if the transmission is going in and out of gear. This causes the vehicle to jerk, and makes it difficult to control the vehicle. This happens intermittently whether it is warmer or colder temperatures. The service dealer reprogrammed the electronic control module, , but this did not remedy the problem. The service dealer attempted to repair the problem numerous times. The attempts to repair the problem included, updating and the replacement of the transmission control unit. This still did not remedy the problem. The dealer reported the problem to the manufacturer, and they sent a technician to determine the problem. The technician reproduced the problem, and said that it was a condition of hill holder function which holds the vehicle in place to approximately 800-1100 rpms, at which it will start to engage the transmission. The manufacturer stated that this was a normal operating procedure for this type of vehicle when the vehicle wa scold. The contact requested for the manufacturer to submit the reason why this was normal operating procedures for the vehicle. The remedy from the manufacturer was for the contact to accelerate more when going up a hill. The second explanation the manufacturer offered was that the jerking of the vehicle was caused by outside temperatures. The california new motor vehicle board requested that the second explanation be put into writing, but the manufacturer refused. Another safety concern bothering the contact was that while driving and upon acceleration the vehicle will stall. When accelerating nothing will happen, the engine will completely lose power. The service dealer stated this was transmission control., but the repairs did not solve the problem.
