Porsches with LiFePO4 Lithium batteries (like mine 2019 Cayenne S) have a software/hardware error that causes the battery to incorrectly send a code to the battery management system so that it will suddenly shutdown the battery permanently and will require a full battery replacement, which the dealers abuse its customers by charging $3,000 to $5,000 dollars and give a battery replacement date as almost one year later. Porsche has internal TSBs but it is not recalling all the customers to have the software update for the controller/sensor bug/defect so that the battery management system will not overcharge the Lithium battery and damage it or cause the battery to issue a software code that preventsbthe battery from waking up or be usable. Texas has temperatures of 110 F, and becoming stranded because the battery gets incorrectly/permanently shutdown is a death sentence to Porsche customers. Porsche is being arrogant with their customers and deeply profiting from this know defect. There are a series of small battery shops that are making money from Porsche’s defective battery controllers/sensors and charge around $500 to $800 to replace the battery sensor/controller and programming the new controller as long as you send them your dead battery. Porsche will not reprogram rhe battery controller/sensor if you replace the original battery, with no explanation on why. Anybody driving a Porsche vehicle that have these battery defects in the controller/sensor/programming will perish, together with their passengers, if the battery gets shutdown and become unusable in a 100+ F, 110+F or if yhey get stranded in a freezing situation. It's a deadly time bomb waiting to happen, if it hasn't happen already since Porsche is not being straightforward. Porsche even sells these defective Lithium LiFePO4 batteries on old cars 2019 models and others, and does not disclose to them that the battery can die unexpectely and hjat the battery is not within the warranty.

Anti-lock Braking System (ABS) failure due to premature degradation of plastic wiring harness connectors for ABS wheel speed sensors located in each wheel well. ABS warning light illuminated alerting to the disabling of the system. Issue confirmed by independent repair facility. Dealer was engaged, but denied coverage due to vehicle being out of warranty and no recalls initiated.

My passenger occupant detector is faulty and unable to recognize if someone is sitting in that seat, therefore the airbags will not deploy in case of an accident. There has been already a recall on this item for my car, but obviously my car was is affected and my VIN isn’t included. So I think it’s needs to be reassessed

While charging the vehicle at a reduced rate (30 amps out of a 40 amp maximum) there was a thermal event in the outlet box that the Mobile Charger Connect was plugged into. There were no witnesses to the event, but it was later noticed that the wall around the outlet was blackened and one prong of the plug had melted the housing of the plug along with the receptacle. The Mobile Charger Connect had previously shown a high temperature warning, so the operating current was reduced from 40 to 30 amps at the direction of service personnel at the dealership. The Mobile Charger Connect was plugged into the specified NEMA 14-50 receptacle that has been in use for the entire duration of ownership.

Owned the car for 6 months and driving down highway and car just shuts off, limited braking and no accelerator. Coasts to a stop and then stops in the middle of the highway. My daughter and i were almost killed by the car behind us. Had to run across highway to get to safety. Porsche North America says this is just a service issue and not a safety issue. Google search reveals this is a widespread problem and not an isolated event as was told to owner. This was my 6th porsche and my last. Was told the power converter from AC to DC was fried and replacement part took almost 4 weeks to get and replace. No prior warnings lamps or indication that something was about to fry and cause the car to become inoperable.

The contact owned a 2016 Porsche Panamera. The contact stated that while driving at 2 MPH and while the contact attempted to make a right turn when the brake pedal was depressed, the brakes failed to engage inadvertently. The steering column also became inoperable. The vehicle would not stop and the steering column would not turn, which resulted in an accident. The vehicle was towed to the dealer, and a police report was filed; however, the vehicle was not diagnosed or repaired. The vehicle was declared a total loss by the Allstate Insurance Adjuster. The contact stated that he had previously experienced brake failure while driving the vehicle and had taken the vehicle to the dealer for servicing, but the dealer could not diagnose the failure at either visit. The manufacturer was made aware of the failure, and a case was filed. The failure mileage was approximately 60,000.

Driving north on Interstate 95 near Stafford, VA and took exit for lunch. Restaurant was right at exit and we entered the parking area. Went to turn and the steering was frozen. Caution light said Power Steering Malfunction and steering could only be turned slightly with maximum effort by driver and passenger. Managed to move car to parking area. Subsequently towed to Porsche dealership in Arlington VA for repair. If this frozen steering had occurred moments earlier on I95, we would have likely crashed with the vehicle suddenly unable to be steered. We were terrified and believe our lives were in jeopardy. The dealer identified the problem as a broken/defective electronic rack & pinion steering unit. Vehicle has approximately 20,000 miles and is always garaged. The failed parts will be available at the dealer when replacement parts are received. There were no warning lights or indication of any problem prior to the event.

While travelling on the freeway on 7/30/23, I experienced a "low oil pressure, shut down engine immediately" warning. I pulled over to the shoulder and was unable to restart the car. It was towed to Porsche Carlsbad dealership where it is awaiting analysis by Porsche. The car has 4900 miles on it and is under the MFG warranty.
