"engine temperature too high. Park vehicle and allow engine to cool". Warning at 50,000 miles which the mechanic says this is a huge problem with all Porsche, Audi and vw due to water coolant changeover valve which fails and also stated that Porsche is aware and should have a "bulletin" open on this issue?.
A coolant hose located on the top of the engine developed a leak that caused the engine to overheat. It was necessary to remove several components of the engine to reach and replace the leaking hose. This repair cost over 5000 dollars with the associated labor cost. Vehicle had less than 6000 miles on it at the time of the incident. It took several weeks to get the needed parts.
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.
The contact owns a 2022 Porsche Cayenne. The contact stated that an abnormal tapping noise was coming from the engine compartment. No warning lights were illuminated at the time of the failure. The vehicle was initially taken to an independent mechanic, who confirmed the tapping noise and referred the contact to an authorized dealer for further inspection. The vehicle was then taken to local dealers, who acknowledged the noise but advised that the vehicle was operating as designed and that the condition was considered normal. The vehicle was not diagnosed or repaired. The vehicle was later taken to new country Porsche greenwich service center, 241 west putnam avenue, greenwich, CT 06830, but the vehicle was not diagnosed or repaired. The tapping noise continued to persist over time. The manufacturer was contacted and confirmed that there was no warranty coverage. The failure mileage was approximately 40,000.
The car is very jerky, I bought in for engine or transmission mount because the idle shakes the whole car. They said its normal. Which I don't think it's normal.
