Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety. Notes: This is the first year Porsche introduced a direct-injection engine to the Cayenne.

2008 Porsche Cayenne Owner Comments

problem #1

Sep 112012

Cayenne 6-cyl

  • 30,000 miles


Within minutes of driving my son to school, I heard a grinding sound from underneath my Cayenne, then a squealing, and the car began to vibrate violently during acceleration. This happened very quickly and was frightening because I was crossing a bridge in morning traffic. The service man at the Porsche dealership told me that this is an ongoing problem with these vehicles and that my drive shaft had come apart. I am a very careful driver and my car has low miles. I believe that there should be a recall and this is safety issue because of how quickly this happened while driving.
