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

S10 direct reply letter to the secretary from regarding having problems with his 2008 Porsche Cayenne. The consumer stated he experienced numerous safety problems with the electrical system and brakes. The consumer stated he filed two separate arbitration against the dealer and the manufacturer. The first arbitration case was settled in 2009, with the expectation all of the problems with the vehicle, current, past and present would be properly identified and resolved. Since the initial arbitration case, the consumer had to take the vehicle back to the dealer 11 times for the same electrical/software problem. The on-going problem uncontrollably affected the proper positioning of the outside mirrors and the overall safety aspect when operating the vehicle. The dealer replaced the onboard computer control module seven times, as their field technical expert suspected there was an unidentifiable electrical shortage or a computer related software virus somewhere within the electrical system. The consumer believed the dealer had no idea how to resolve the problem.
