“I own a 2005 Porsche cayenne. Since owning this truck there have been numerous items that have gone wrong. All the main computers had to be replaced, front drive shaft, transmission, and now a coolant tube. The last item is my concern, which cost $2,800.00 to fix on a truck that has 71,000 miles on it. When it was taken to the dealer I was told that all the cayenne?s from 2003 ? 2006 have to have this part changed (it?s made of plastic), because it breaks. …”
NHTSA complaint #10217698, filed 2008-02, 78,486 miles“I was driving a Porsche Cayenne S today on highway at 65mph. The car unexpectedly slowed down by around 20 miles for about 10 seconds. 5 minutes later, same problem occurred again and then the engine stalled, and the steering wheel locked. It is very dangerous to stall on highway, without too much control on steering wheel. The dealer said they could not find the problem.”
NHTSA complaint #10244267, filed 2008-10, 44,400 miles“The contact owns a 2005 Porsche Cayenne S. The contact stated that the radiator pipe was fractured, causing anti freeze to leak from the vehicle. The vehicle was towed to the dealer where the original hose lines were replaced with metal lines due to corrosion. The manufacturer was made aware of the failure however, did not offer any assistance. The current mileage was 75,000 and the approximate failure mileage was 74,800.”
