Q: What would cause a loud rattling under car when idling & foot is off the clutch? on 2003 Nissan 350Z

Rookie cbe0621eac06868b3efe0d8d1d3611e23c60d3114864ea2ec19a68cfbd3eebab
When the car is in neutral and my foot is off the clutch there is a loud rattling from under the car, once the clutch is engaged the noise stops. The noise is progressively getting worse and much more frequent. Nissan service department cannot seem to identify the problem. Please help me.

Sounds like the throw out bearing is bad in your clutch. You need to get it repaired as soon as possible. Eventually, it will shatter and you wont be going anywhere. Find your local auto repair shop ASAP. Goodluck
