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. …”

When I connect a digital break controller or 7 pin cable with a trailer the car doesn't not communicate with the break controller. …”

This is a safety risk in bumper to bumper traffic as the car can suddenly jump forward a few feet more than intended by normal breaking. Even when driving and breaking explicitly to compensate for this transmission / breaking defect, the lurging issue cannot be avoided. …”
