Odometer Fraud. The contact purchased a 2021 Porsche Cayenne. It was discovered that there was a mileage discrepancy. The vehicle was a dealer sale.

The contact had taken the vehicle to another dealer for other repairs, and the dealer informed the contact that the vehicle was flagged for Odometer Fraud, and the actual mileage was 90,000. The dealer found an odometer tampering device still located on the vehicle, but deactivated the device. The contact called the State Attorney General's Office for New Jersey.
Instrument cluster anti-glare film or delamination on center and left instrument cluster. The film is wearing away in certain irregular sport and shapes. The overall wear is impacting the visibility to the center cluster under certain conditions leading to obscure visibility to important information, including vehicle speed or other warning light. It has been raised to the dealer, then to Porsche NA, but the dealer has stated they (Porsche NA) will not cover the repair, even though the vehicle is under a CPO warranty. This first started appearing this year and has gotten worse over time. No unusual cleaning, harsh chemicals or other abrasive object were used. The nature of film is slick issue is inconsistent with this and does not appear on other parts of the user interface - just the more important ones. …
Air bags
I am reporting a safety defect with my 2021 Porsche Cayenne GTS. The leather dashboard is delaminating and lifting away from its underlying structure. This defect is concerning because: The delamination is occurring on the drivers side but will eventually expand in the area covering the passenger-side airbag. If the airbag deploys, the raised/lifted dashboard material may interfere with or obstruct proper deployment, posing a serious risk to passenger safety. Porsche Cars North America (PNA) has been notified, but they classify this issue as "cosmetic" and refuse to repair it voluntarily under warranty or goodwill. Furthermore, The issue was not disclosed by the dealer at purchase. I have consulted two Porsche dealerships, both of which confirmed Porsche considers this a cosmetic defect not covered by the Certified Pre Owned warranty. …
Over approximately the past month, the leather covering on the dashboard of my 2021 Porsche Cayenne has rapidly begun lifting, buckling, and separating across a substantial portion of the dashboard. The deformation has become increasingly pronounced in a short period of time despite normal use and careful maintenance of the vehicle. I am concerned that this may present a safety issue because the passenger airbag deploys through the dashboard area. The dashboard material is visibly distorted and separating, and I am concerned that this deformation could potentially interfere with the intended deployment path or performance of the passenger airbag in a collision. This does not appear to be normal cosmetic wear. The affected area is not routinely touched or subjected to ordinary wear, and the condition developed quickly on a relatively recent vehicle. …
Engine & cooling
While coming to a stop the vehicle lurches around 1200 rpms as the rpms are falling. The vehicle appears to already be in 1st gear when this happens. This can be replicated in all driving modes. observation: when braking or even when coasting to a stop the vehicle will slow down rapidly, as if the brakes are being tapped hard (the brake pressure is constant and occurs even when not braking) for a brief second and then release causing a lurching motion. This lurching motion is enough to concern while driving as a possible loss of traction. it feels as if the car is engine braking. This issue puts the driver, passengers, and other vehicles at a safety risk. I have had passengers state that it gives them motion sickness. I have reported this to the dealer and they had the car twice. The second time was for a substantial amount of time. …
On my 2021 Porsche Cayenne Base, which is equipped with the 3.0L V6 EA839 engine, I brought the vehicle to the dealership for a recall service. During inspection, the dealership found a leaking water pump and quoted $8,500 for repairs. There were no visible signs of a coolant leak on the ground, indicating an internal seal failure. My independent technician confirmed that coolant is leaking internally into the vacuum system. This EA839 engine architecture is shared across multiple Volkswagen Group models, including Audi A6, A7, A8, Q7, and Q8, where this water pump internal leak is a known, widespread manufacturer defect that has already triggered class action lawsuits.
