Thanks Guys! I realize there is a difference between service campaigns and recalls. I did get some information from nhtsa.com that discussed some problems that they have had with the Cayenne. Another member of the group said that she had found recall information about an inadequate ground connection between the spiral ring of the tank filler neck and the pipie to the fuel tank. But, acc. to the nhtsa, it may only affect about 35 vehicles. Thanks for the other info source ideas! I'll check them out and be back if I have more questions.

Thanks again, Kara
