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.

2003 Porsche Boxster Owner Comments

problem #1

  • 32,500 miles


1. I purchased this car new. It is my daily driver. Only serviced my Porsche mechanics. It had 32,500 miles at time of failure. After leaving a doctor's appointment, I noticed an unusual sound coming from the engine compartment. Not very load. I thought it had caught a piece of debris in the belt system. Drove it slowly home, and the sound got progressively louder. The next morning there was a puddle of oil under the car. I called the Porsche dealer in mobile, al for a tow truck. 2. I was told by the Porsche service manager that the car had experienced the infamous intermediate shaft (ims) failure, and that I would need a new engine. I was told there is little to no warning of this failure, and they are almost always catastrophic. Requiring complete engine replacement. 3. Porsche North America was contacted with all pertinent information. They responded with an offer to cover half the cost of a factory rebuilt engine. I would pay the other half, plus all labor and towing costs. This replacement will cost me over $11,000 !!!
