Just started noticing a hissing sound when the car is at idle and it gets progressively worse when i accelerate. Anybody know what it is?? The car only has 12000 miles on it.
Could be a leak at the exhaust manifold. Get an automotive stethescope and see where the noise is coming from or just take it to the dealer, it's under warranty, enjoy the loaner.
Ok, I took the car to the dealer and it turned out to be a bearing on the pulley. The mechanic said they have replaced quite a few of these so obviously there is a reaccuring problem with the part. thanks for replying.
