2009 Porsche Cayenne Turbo S 4dr SUV AWD (4.8L 8cyl Turbo 6A)
This is the BEST driving car I have ever had, BUT the PCM does not work. It resets every 3 min and Porsche does NOT have a fix. It has been over 4 months and still no fix. My understanding that ALL top level Porsches have this problem. Too bad because it is the best driving car I have ever had. I will not buy another.
