Strange Buzz Then Hissing Noise Near Rear of Car
 

i noticed a funny thing with my car yesterday...

after parking & shutting off the engine, i noticed and audible buzzing sound coming from the rear end of the car- seems louder near the rear right wheel. then after it buzzed for about 2 or 3 minutes, the car makes a single loud "hiss" sound- ie like a single loud burst of air being let out of a tire or something. then complete silence.

any ideas what this might be? it's almost like my car has to burp itself after the engine is turned off. very weird...

sounds like your fuel pump.

How mant miles on your car?

thanks for the feedback guys.

i have 9,200 miles... no CEL's on the dashboard. i am due for 9,700 oil change soon. i wonder what is the best way to describe the issue to mazda so they know what to look for...

thanks again for the feedback.
