Complaints for the 2020 Porsche Cayenne are spread thinly across systems, with no single area drawing a dominant cluster. Engine complaints describe an abnormal tapping noise and a coolant hose leak that caused overheating at low mileage, requiring significant disassembly to reach the failed component. Brake complaints center on a pronounced lurching and irregular deceleration pattern when coming to a stop, which at least one owner describes as consistent enough to cause discomfort on every drive. Electrical system complaints involve the seatbelt and airbag warning lights and chimes activating persistently on the dashboard, in some cases regardless of whether the belt is buckled, and one owner separately reports a driver's side seatbelt that became physically unable to latch.

By System
The 2020 Porsche Cayenne has 4 recalls, the most serious involving the front passenger airbag, which may fail to deploy in a crash on certain Coupe and GTS variants.
On the braking side, a separate recall addresses worn brake pads that may not trigger a warning to the driver, leaving the vehicle with reduced stopping power without any alert. The transmission has a potential leak point where a fluid line can seep automatic transmission fluid onto the road, making the surface slippery for following vehicles. There is also a visibility concern: the rearview camera may fail to show an image when the vehicle is shifted into reverse, reducing the driver's view of what is behind the car.
