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 sensor on Coupe and GTS Coupe trims, where a missing seat heating element can prevent the airbag from deploying in a crash.
The visibility cluster includes a rearview camera that can fail to display an image when reversing, leaving the driver without a view of what is directly behind the vehicle. On the drivetrain side, a transmission oil pipe can develop a leak and drip automatic transmission fluid onto the road surface, creating a slipping hazard for following traffic. There is also a braking concern: the brake pad wear indicator can fail to alert the driver when pads are worn down, meaning the brakes may not stop the vehicle as expected without the driver realizing there is a problem.
