I got out of my car today and I heard this "ssst" "sssssttt" sounds coming out of the bottom of the car. It was coming out by the back passenger tire. I think there's a leak in the exhaust system...but has anyone every had this occur to them?

I bought the car at 200 some-odd miles and I think because it was used as a test-drive car, the break-in period was messed up when peopled "tested" the car. When I got the car, it actually was fine...but now it's already making little problems...I'm almost at the 1,200 mile point and I've only pushed the car over 4000 rpms a few times. Although I really like the car, I hope it's reliable in the long run...

I think that everyone has that hiss at the rear drivers tire. It comes and goes. I still haven't figured out what it is yet, but it's most likely not an exhaust leak.

that's wierd, have you told the dealer about it? It's only started the last couple of days and I've had the car for about a week and a half

It seems that it is most likely the fuel pump. Check out these threads:

There was a much longer thread that I can't seem to find right now. At least you know that you're not the only one that hears it though.
