problem details
My cayenne's coolant pipes broke at 84k miles. The symptom of this is when all your radiator fluid starts pouring out into the street. It seems like all pre-05 cayenne's have this issue eventually. It's causes by defective plastic coolant pipes. The fix is to have Porsche "upgrade" them to metal pipes for $3,000. There is currently a class action lawsuit pending for this.

I was coming out a stop light, and then I noticed fluid spewing out the back of the car. When I got home, coolant light was on; looked inside the reservoir and it was empty. Filled it up; and it just leaked out on to the driveway.
