2004 Porsche Cayenne Owner Comments

problem #1

May 212008


  • 52,764 miles


Beginning in August 2007, my car experienced transmission shifting problems and eventually had to have the control unit replaced. Afterwards the transmission shifted differently, but I assumed that was related to the new control unit. In early 2008, the transmission seemed to run rougher during warm up and occasionally the right tire would "skip" as if traction control engaged for a brief period. I assumed (incorrectly) that this was due to tire wear. Finally, in May 2008, the drive shaft failed. This was two months after the warranty period and at 52,764 miles. I have read online that this driveshaft has had many failures, and that dealerships keep several on hand to address the related problems. With that in mind, I requested that Porsche replace the driveshaft under warranty. The part cost $895.51 plus $69.40 in tax for a total of $964.91. Since the labor was performed at my local service center, I am requesting only reimbursement for the part. I have saved the failed part and can also supply you with the original paperwork. I am attaching copies of the repair bill (import specialties) and the previous warranty work (newport auto center). Porsche denied the claim on June 9, 2008. The driveshaft represents both a defective part and a potential for a dangerous situation it the unit failed at a high speed.
