I'm writing this complaint to your Agency and urging you to investigate 2008 Porsche Cayennes the safety quality of cardan drive shaft. On May 9, 2015, in the evening, I was driving my Cayenne heading home at the speed of less than 55 miles per hour as I just got on the highway. I suddenly heard a loud noise as an explosion from the underneath of my car. Then, I heard the metal grinding noise. I was so scared. I didnt know what happened to my car. The car was still driving fine, and there was no indication on the dashboard that my car was in trouble. Luckily, there was no traffic behind me, so I reduced my speed to less than 30 miles on the highway and got off the next exit. I stopped by at the nearest gas station. I was checking the underneath of my SUV. I thought perhaps, the muffler was falling off. Well, nothing was falling off my car. So, I drove it very slowly to home because as the car climbing the hill, the metal grinding noise was getting louder. Next day, I had an auto mechanic to check my car, and he told me that the center bearing to the drive shaft was loosening. He told me that I cannot drive the car because in any minute the bearing could be snapped. He advised me to tow my car to a Porsche dealer's services shop. And, I did it. At a Porsche dealers service department, they told me that the cardan drive shaft was broken. I couldnt believe that my car only had 51,871 miles, and the center bearing was broken on the highway suddenly. Per internet research, the average drive shift could be last for 160,000 miles. I really didnt expect this kind of poor safety quality from a Porsche Cayenne. If you search the center bearing issue of Porsche Cayenne on the internet, you can find a lot of similar stories posted online. Porsche Cayenne has a powerful engine. However, from my incident, I believe the center bearing is the weakest link of the SUV.
