Does Your Car Fart?

It could be coming from the anti-lock brake motor. When the car is started the brake pressure to the anti-lock system is maintained by an electric pump. You may be hearing the pump motor as you are backing out of the driveway. I haven't noticed this in my 2013 Accord but I have noticed it in my 2000 Accord. I have highlighted the section in the owner's manual. When backing up it may be difficult to determine if the motor sound is coming from the front or the rear of the car.

Is could any one of these...

The Back Seat Fart - This is a fart that occurs only in automobiles. It is identified chiefly by odor. The Back Seat Fart can usually be concealed by traffic noise as it is an eased-out fart and not very loud. But its foul odor will give it away, due to the way air moves around in a car. It is often followed by someone saying, "Who farted in the back seat?"

The Burning Brakes Fart - A silent fart identified by odor alone. Usually and adult fart, occurring while the adult is driving a car or has a front seat passenger who farts. The Burning Brakes Fart actually does smell a little like burning brakes, and seems to hang around longer than most farts Which gives whoever farted a chance to make a big show of checking to see if the emergency brake has been left on. When he finds it hasn't you know who farted. A common automobile fart.

The Car Door Fart - Either a group one or a group two fart. Very tricky. It is meant to be a concealed fart. A matter of close timing is involved, the farter trying to fart at the exact moment he slams the car door shut. It is usually a good loud fart. It is one of the funnier farts when it doesn't work, which is almost every time. It is a desperation fart and not too common.

I think the ABS idea may be what's going on.

It happens for instance after I back out of the garage, and have pulled out down the driveway 100-300 feet. It has happened at work several times too, although I usually have the radio cranking since I'm alone in the car at that point, and probably don't usually hear it.

It never happens when I'm backing up out of the garage, it takes longer than that to happen.

And I'm not positive, but I'd swear that it is coming from the rear of the car. At least that's where the sound appears to be coming from. I have to lights on the dash lit up, and everything seems to be working correctly, so I guess I won't sweat it.

If I still hear it come time for my next service, I'll mention it to them I guess.

My noise canceling is 'canceled' on the rear of my car, as I have a custom sub installed with amp in the rear.

Thanks for thinking about this with me, I appreciate the effort.
