Apparently the Cayenne isn't very reliable. Consumer Reports says it's 80% less reliable than the average vehicle which pulled Porsche to 2nd from last (beating only Jaguar) in their reliability list for 2011. Smiley

Interesting to note that the Carrera S is the third best in terms of reliability for individual cars, beaten by a Lexus and the 135i.
