“There is a major issue with the coolant pump/water pump on the V8 4.0L engine. Every 30,000ish miles I’ve had to have a water pump replaced in my vehicle, Porsche NA claims they redesigned the pump and it fails in the same amount of time. Rennlist Porsche worldwide forums there are 28 threads of people having water pumps/coolant pumps replaced at the tune of $9,000-$12,000 because 70-80% of the front end of the Cayenne has to be removed to get to the water pump. The pump needs to be made out of more durable materials for durability and longevity. …”
