“The coolant pipes failed on a recent road trip due to the pipes cracking. I lost all of my coolant and overheated my engine. This seems to be a common theme amongst 2004-2006 cayenne models as there is currently a class action lawsuit pending.”

I was forced to pay for repairs when the mechanic received a bulletin from Porsche about the problem. Contacted Porsche and they stated the dealer brumos Porsche should not have sold the car without updating the coolant pipes. I still had to pay over $2,000 dollars.”

“I own a Porsche, Cayenne S 2006 model. I was traveling to las vegas, nv from home (garden grove, ca) . All of sudden there was coolant check signal came on so I have exited from freeway and added more coolant. However the coolant check signal wouldn't go off and the temp went up so high that I had to pull over to the side of the road. Make the story short, my whole family spent next 5 hours out on 110f sunlight without AC. I have found out that coolant pipes were made with plastic which cannot withhold the heat which vehicle generates. …”
