Hello, I just recently got my first Mustang and LOVE IT! This car has been nothing but a dream so far. Unfortunately it's making a few weird noises that are making me cringe.

My uncle knows a ton about cars/mustangs and can diagnose it next week. I was just wondering if anyone had these same problems or had a general idea of what it could be, so I know what to look for.

The first noise happens every time I turn the car off. It will hiss for 10 or so seconds under the hood. I lifted it up and nothing seems to happen when it does it, so my best guess was something with the radiator. I'm not very car smart though, so keep that in mind =P.

The second noise happens in first or second gear. If i'm pulling out of somewhere slowly, it makes a weird noise until I shift. The noise keeps happening about 4 seconds after I shift and give it gas as well. The noise continues regardless if the clutch is initiated or not.

The last noise started this morning. Sometimes when turning slowly, it kind of makes a popping sound. (sounds like it's coming from the tire well)

I know these aren't very descriptive and could quite possibly be anything, but even a guess would help ^^.

I can upload some videos to youtube tomorrow morning if you believe it will help.

Thanks a lot!

My guess on the hiss noise is that is normal.
could be the TB release back pressure when car engine is shut off.
"like a quick puff of air sound" or could be related to AC compressor or heating system vent doors pressure release.?

As for popping in front end.
Could be rack bushings " believe member Cliffy K has a right up on it" or could be ball joints or tie rod ends.

Tranny noise TOB or Syncos ? Not sure but I know TOB bearing noise is very common on Fords and mostly Mustangs.


GL and enjoy that new Mustang theyre great cars.

My possible guess for the hiss noise is condensation dripping on the exhaust pipes. Mine does it every day when I get home, it's been averaging 80 degrees here recently and it will do it in warm weather regardless of whether I have the A/C on or not.

Mine hisses when I close to door after a fairly long drive so I would assume that it is just normal
