The Adaptive Cruise Control keeps faulting randomly and triggering the seatbelt warning â ï¸. 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.

We have contacted several Porsche dealerships in our area on several occasions and the manufacturer has failed to remedy this problem. We first contacted a dealership about the issue in March 2023, and Porsche has still failed to remedy this problem.
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. Was told that it could be a month or more before they know. My complaint is not the defect (which Porsche identified); but, the manner in which this is being handled. Parts for a defect that sounds this serious should be available before sending ominous-sounding recall notices to customers.
The contact owns a 2020 Porsche Panamera. The contact stated that while driving approximately 35 MPH, the vehicle started losing motive power, jerked, and the vehicle would not properly accelerate. The vehicle was later taken to the local dealer who was unable to duplicate the failure. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was 50,000.
