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.

A D V E R T I S E M E N T S

Bought my used 2004 911 Carrera September 2011. In May 2012, catastrophic engine failure apparently due to timing chain coming off and ruining the whole engine. Heard some terrible rattling in the engine and suddenly the engine cut out. I barely escaped with my life due to cars coming up behind me and I had no power -I was at my own peril barely able to roll over to the side of the highway to safety. It was a scary experience. I have been waiting to hear back from Porsche whether it is IMS failure or the timing chain-in any case the engine is gone. Even though the car is no longer under warranty and I bought it from a very reputable dealer with approx. 50,000 miles-this should not be happening to a car I just paid $35,000 for. Checking the internet it is apparent that Porsche is very aware of these engine defects from 1999-2004 but chooses to ignore them and their clients. The 2005 911 was upgraded to correct these defects. This is a well known fact in the industry and proves that something was drastically wrong with the 2004 model.

This is my 6th Porsche (2 owned in Germany and 4 in the US). It is currently with the Porsche dealer who has told me to remove the car from the dealership within the next few days and that Porsche Cars USA Atlanta does not want to get involved. Having read all the reports about the 2004 911 catastrophic engine defects I am just wondering how Porsche can get away with this without some negative publicity. In all these years, none of my Porsches ever had a serious problem. 62,000 miles is nothing for a Porsche. I am so upset that I cannot in good conscience ever buy another Porsche-besides whichever way this problem gets resolved I will never feel safe driving this car again and will be looking to get rid of it asap. Porsches service and customer care (Goodwill Program) so far after 3 weeks of waiting is a joke and does not fit with the image they successfully portray to get us to buy these cars thinking we are buying quality and service.

Carrera GT Carrara 4S 3.6L

  • CVT transmission
  • 18,000 miles

Everyone is aware of this problem if you own a Boxter or 911. It is also apparent that if you are out of warranty, it is on you to fix. Porsche Goodwill Owners Assistance is absolutely useless. They just go through the motions to act as if they care. From what I understand from my local dealer is that they had never any success in PGOA. Having said this, I'm trying to get some facts on number of failures and names and vin#'s of cars that have failed. I will be buying a advertisement page on WSJ for an ad on this issue. I'm afraid the class action lawsuit is not really going to help anyone except lawyers. If you are a victim, please e-mail me at through this website. I will be in contact with you. Let's all get together and show Porsche how unsatisfied we are as customers!

Carrera GT Coupe

These cars are meant to be bullet proof and I've blown 2 engines in two years driving sensibly - My recommendation would be to leave well alone as the service and customer care is appalling.
