Driveshaft problems of the 2005 Porsche Cayenne

Driving from NY city on November 20, 2018 all of a sudden start hearing loud clunking/thumping noise from the under of the car. It was scary. Drove home very slowly with flashers on. Took the car to the Porsche dealer in rochester and they diagnose and quote me close to $2000 to replace the cardan drive shaft. I do not have the money and car is parked in the driveway at home.

Tl the contact owns a 2005 Porsche Cayenne. While driving approximately 35 mph, the contact heard an abnormal clanking noise underneath the vehicle. The contact drove to an independent mechanic where it was diagnosed that the driveshaft was detached and split in half and needed to be replaced. The vehicle was not repaired. The vehicle was not taken to a dealer. The manufacturer was notified of the failure and did not assist. The approximate failure mileage was 110,000.

Since I have had the vehicle I have had to replace the drive shaft 3 times. Porsche replaced it once under warranty and the other two times I had to pay in excess of $900. 00 to have it replaced. I have been told by Porsche that it has a defiective rubber seal and when the seal fails so does he drive shaft. This is a common defect and is know by Porsche at the dealers and the manufacturer. They have acknowledged the defect to me. My concern is if the drive shaft totally fails and breaks, not just flexing and hitting the floor, it could cause an accident by making the vehicle go out of control.
