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.

Porsche lurches, jerks, thuds, intermittent power loss when accelerating to pass another car. Engine, transmission/turbo system faulty and hazardous as power loss occurs when quick speed-up when passing power is critically needed.

Engine coolant hoses are leaking antifreeze. Everytime I pour antifreeze into the car it comes out, im afraid it might damage something else, like the engine etc. They have plastic hoses on them.

Upon taking the vehicle out of the driveway I started hearing a ticking sound coming from the engine, something like a lifter hitting the block. I pulled back in to my driveway and called a repair shop and scheduled an appointment. When meeting with the technician I was informed that the engine had a scored cylinder and that it is a common issue with the model and year. The only recourse to fix the issue would be to replace the engine. A replacement engine would cost $17 -35,000 - more than the vehicle is worth. If I were to replace it with a used engine, I would be destined for a repeat of the same issue. If this issue is such a common problem why has there not been a recall for these vehicles? I have contacted the manufacturer and was told that I would need to have a authorized service dealership make the diagnosis I have already been told, but there is not a authorized dealership within 500 miles of my location.

At 38,785 miles coolant pipes leaking and replaced. After repair "internal engine noise" and noise is now louder and engine use more oil. Took to local Porsche dealer vehicle still at Porsche dealer because dealer states" engine needs replaced" because if overheated due to coolant pipe failure pistons walls damaged. Dealer checking with Porsche to find out if they will pay something or all of cost to replace engine. Cayenne at Porsche dealer for over 60 days with no outcome as to what Porsche will pay. Could cost up to $20,000 if invoiced to me.
