NHTSA complaint #11511948, filed 2023-03, 50,000 miles

Other or unknown: “Received Manufacturer Recall Number APA1, NHTSA Recall Number 23V033, regarding recall. The recall summary stated that on the affected vehicles, including our vehicle, there is a possibility of humidity ingress into the external coolant pump for the climate control system. The recall also stated that this issue could cause a short circuit and, in some instances, thermal damage. This can occur even after the vehicle is turned off, if the engine residual heat function is activated by the operator by pressing the AUTO-REST button on the central control panel. …”

NHTSA complaint #11530019, filed 2023-07

Electrical system: “Received a recall notice from Porsche yesterday regarding a potential wiring problem with the climate control coolant pump that, under certain humid conditions, could result in an electrical short and engine fire. In the notice, they recommend “out of an abundance of caution” to “park the vehicle outside and away from other vehicles or structures”. Sounds serious. Called my Porsche dealer in Atlanta to schedule an appointment ASAP to get the problem repaired. The repair parts are unavailable and they don’t know when they will be shipped. …”

Forward collision avoidance: “The Adaptive Cruise Control keeps faulting randomly and triggering the seatbelt warning ⚠️. Also when the adaptive cruise control fails the cruise control disengaes altogether. This is very dangerous when driving. I have taken this car to the dealership 4 times within 2 months for this problem and no one can fix it.”
