Power Train Problems of Porsche 911 Turbo

Cause of problem is due to clutch master slave cylinder internal leak. Premature failure of slave cylinder. Clutch paddle was depress and will not return fully. Few days later, clutch paddle would stay put on the floor of the car. Check out the blog and it is a very common premature failure for this typical model however, Porsche didn't sell enough for everyone to get on board with the complaint.

I was driving the car when suddenly the low coolant light came on. Instantly, temperature started rising and I shut it down. I wasn't sure what was wrong but I found coolant all over the rear wheels and tires. After sitting on side of road, another Porsche owner stopped by. We thought the car was just overheating, so we added water. It seemed fine so I started driving home and then it happened again. We put the car on my buddy's lift and identified that the coolant was leaking from the top of the motor. After doing some research and talking to my mechanic, it appears that the coolant hoses that are bonded to the exchanger have separated. Apparently, the hose is glued to the fitting. They are both metal. My mechanic is still trying to identify a permanent fix but as of yet we haven't fixed it. I am waiting a bit to figure out the best way to fix the car to avoid future failure. The car has low miles and I am concerned after doing some research that it could happen again.

I am concerned that this coolant hose issue will effect my car and cause a safety hazard. I feel that there should be a recall from Porsche to fix this. I understand that the engine coolant hose is glued on using epoxy instead of welded or threaded. Also, I don't want to have to shell out $3. 5k to fix this should it fail because my warranty has expired. If the actual engine blows as a result of this failure I am looking at well over $35000 to replace the engine and fix the problem. My engine coolant temperature sensor has already failed and was replaced on 08/17/2012.

I have been informed by my Porsche technician that Porsche used an inferior and mechanically poor design for the engine coolant lines. They are glued together in a place where they get hot. After several heat cycles, they will fail. All cars with this engine design will have this failure over time. If the coolant lines fail whils the car is moving, the slick coolant can get on the tires and cause an accident. Also, the engine can overheat with a replacement cost of over $20,000. Porsche is aware of this, as they have used a superior threaded design on their race cars with this engine. I have been advised that this will take thousands of dollars to fix, and the car will be out of service for weeks.
