Example complaints

Engine cooling: “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

Vehicle speed control: “The vehicle stalled while accelerating from a stop then lunges forward. The vehicle was taken to the dealer who indicated that this is the way the vehicle was designed.”

NHTSA complaint #10115358, filed 2005-03, 1 miles

Electrical system: “The contact owns a 2005 Porsche Cayenne S. The contact stated that instrument panel was failing and the turn signals and speedomitor were inoperable. The vehicle was taken to the dealer and they told the contact that the entire instrument panel would need to be removed to replace a microchip at a cost of $2000. The failure mileage was 76,621 and the current mileage is 76,668. Updated 09/07/11”

NHTSA complaint #10401249, filed 2011-05, 76,621 miles

Engine: “The engine has plastic coolant pipes between the front and back of the engine. They failed and dumped all the coolant out while on the road. Car was disabled and had to be towed. After researching, it's concluded that this is a very common failure in cayennes with a v8 engine at about 60000 miles. Mine had 61000. This is a safety concern. The car can be disabled at anytime. Also, the repair is very costly, exceeding 3000 usd for parts and labor.”
