High Performance 19" tires worn down beyond safe usage after 20,000 miles.
Tire Pressure Monitoring system frequently malfunctions.
Malfunctions in the center console control system ranging from the clock, to the GPS system, to the radio control.
For an SUV of it's size this car has amazing engine power and acceleration.
Towing couldn't be easier - Driving actually feels lighter while towing with this car then it did with my Jeep Grand Cherokee normally, no offense to the Jeep.
As far as driving in the snow and ice, I am hardly impressed with Porsche Traction Managment (PTM) and the car's handeling in these situations.
Seats are not what I'd call comfortable. Incredibly stiff, especially in the back, and with the already stiff ride of the Cayenne, this makes long trips a hassel.
As far as customer service, I am very unhappy. Having bought the car in it's first year of production, many of the features I ordered were completly left out due to "problems in Stutgart" and glitches continuously occur.
Aside from this, compared to what I am used to this car is generally incredible. The amazing power and style screams Porsche at every accelleration along with one of the finest luxary interiors I've seen on a car.
I agree that the seats, front and rear, are the most uncomfortable I have encountered. The ride is stiff, harsh, and long-trips are unbearable around NY City. I hate my Cayenne and cannot wait until the lease is up to get rid if it.
