Chronological view of owner reports
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. Expecting customers to replace water pumps every 30K miles is ridiculous. My 3rd water pump in 95K miles is being replaced as I type this right now. The dealership Porsche of Wallingford, CT, has 3 other customer Cayennes now that also need water pumps. Porsche USA and AG/Germany need to issue a 15 year/unlimited miles warranty on this water pump, like they’ve had to do with window switches, emissions valves, and other parts they have gotten sued for and now have 15 year warranties.
