Manual Transmission problems of the 2005 Nissan 350Z

I have a 2005 Nissan 350z. It only has 10,000 miles on it and I have a vibrating noise coming from behind my front driver side tire when the car is in neutral and the clutch is out. When I push the clutch in the noise goes away, when I let it back out the noise comes back. My previous car was a 99 Nissan sentra. I put over a hundred thousand miles on that car and never even saw a check engine light. Now I have a $30,000 car with only 10,000 miles on it and my tranny is going out and I'm not the only person with this problem.

2005 Nissan 350z. The consumer states the vehicle stalls when going over 70 mph,this also occurs at lower speeds. There is no warning that this is going to occur. The service engine soon light comes on after the vehicle completely looses power. The vehicle has to be turned all the way off to be started. The vehicle has been taken to the dealership and they replaced the crank shaft sensor. The problem is happening again. This has happened approximately 7 times. This has not caused any accidents.
