I had my engine on and I was trying to check my winter tire air pressure... and at the rear right tire, I heard air leaking sound.. it was loud that i could notice it right away... so, i figured some nails or some sharp oject got into tire and was casuing air leaking sound.. so, i jacked my car up and removed rim and checked the tires but no signs of puncture nor nails or sharp objects.. i wanted to find out where that air leak sound was coming from so i turned on the engine and i heard air leaking again w/o my rims on.... where is that sound coming from??? is it normal?? anybody experienced this noise????

 

I've heard that noise and it's the electric fuel pump in the tank. No worries.

oh... i.c... i'm glad that it is normal sound...... cuz i have so many rattles in my car that i said to my self that if i find one more rattles, i'll sell my G for something else... i know sad story but like other people mention, it is not normal for $40k car...
