Transmission Noise problems of the 2006 Mitsubishi Eclipse

I am a current owner of a 2006 Mitsubishi Eclipse gt with a 6-speed manual transmission. I am the only owner of this vehicle. I have less than 22,000 miles on the vehicle as of today and recently I have been hearing a noise coming from my transmission while I am in neutral. ¿ I recently returned to the dealership for a previous recall situation that needed to be addressed. I questioned the noise and I was told that it was the throw-out bearing on the clutch. I asked if the part can be replaced and if it was covered under warranty. I was told it was not covered under warranty and they usually replaced the entire clutch due to the bearing causing damage to the clutch assembly itself. When I asked why the bearing was not covered, I was told it was a wearable part. I was told that this clutch replacement could cost at least $1,000. I have been driving manual transmission-vehicles for over 13 years and have never had a clutch problem. The previous cars I owned prior to the Eclipse purchase have been sold to family and friends and they also have not had any problems with the clutch. I currently own a 20 year old vehicle with almost 200,000 miles and I have never had problem with the clutch. I understand that the clutch is a wearable part, however, I have seen other complaints dealing with the same problem (complaint number: 10222679, 10224311, 10178777, 10173845, 10163231) and I believe that a clutch should not need replacing already in a brand-new vehicle. I have also e-mailed Mitsubishi over two weeks ago for any information and/or assistance and I have not received a response. I feel that this is very unprofessional being a customer. I believe due to multiple complaints of the same origin, that this part could be faulty and should be covered under warranty. I continue to have the "noise" coming from my transmission and no assistance and/or information from Mitsubishi. After this ordeal, I refuse to ever purchase another Mitsubishi.
