I've had my Mazda 6s now for about 7 months and it's got about 13,000 miles on it, and lately my clutch has begun to chatter a little bit when it's cold. Anybody else ever heard of this problem on a 6? I've always driven cars with manual transmissions and I am very good and not abusing the clutch, so there's definitely no reason why this clutch should be showing signs of wear yet. If my clutch starts to get worse and the dealership won't cover it under warranty, I'm going to raise hell. Anyways, any insight would be appreciated.
