NHTSA lists 1 safety recall and 5 owner complaints for the 2020 Porsche Panamera. Most complaints involve engine (2) and forward collision avoidance (1). The EPA rates it 18–22 mpg combined.
Porsche Cars North America, Inc. (Porsche) is recalling certain 2017-2021 Panamera, Panamera 4, Panamera GTS and Panamera Turbo vehicles. Please see the recall report for a complete list of specific model names and model years. Humidity may enter the external coolant pump for the climate control system and cause an electrical short circuit.
Complaints are unverified owner reports to NHTSA and are not normalized for sales volume. One complaint can cite several components.
“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.”
“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.”
“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.”
Towing, payload and dimensions aren’t in the EPA or NHTSA data, so we don’t list them.
