| Description of the problem | The vehicle lost most of it's power from an engine failure while traveling at approximately 60 mph on the interstate almost causing me to be rear-ended and a multi-car pileup. I was very fortunate to escape a major accident. An independent porsche repair shop, eurasian auto, "bore scoring" on cylinder 5. Factory dealer, porsche of birmingham, confirmed that diagnosis. The automobile only has 30,000 miles on it. The engine now needs to be completely rebuilt. I searched online and found numerous examples of this same thing happening happening to other owners of 911s with this model engine. It was used in 911s between 05 and 09. It occurs in both the 3,6 liter engine and the higher horse power 3. 8. Some reports say the failure is even more prevalent in the 3. 8 liter which is in the s version. My car is a 3. 8 liter s version. The problem is so prevalent that several companies now specialize in remanufacturing 05 to 09 911 engines that have suffered bore scoring and providing "fixes" so that bore scoring will not happen again. These companies include flat six innovations, rnd, and struttcars. If you look at any of these companies websites you will see an explanation of the problem and their solutions. Porsche is aware of the problem and has refused to address the issue. So that you will know this safety issue is not an isolated issue, i enclose several online references to the problem. Also i will keep the car garaged in it's current condition for 5 months if you want to test it. |
