I'm sure this is normal but when shutting off the engine it doesn't just quielty stop. If you listen closely it goes something like "swooooosh" in a declining tone. That's the best way I can describe it.

It starts fine and runs quietly but makes this gentle swoosh when it's shut off. Is this something other people hear? I don't think there's a problem but it just sounds odd.

Anyone else hearing this or do I have superhuman hearing?

Maybe Weather?

Since you didn't post a location I can't really tell you for sure, but it sounds like maybe your car fan. Just a wild guess, cause otherwise I have no idea.

noise

I believe it's the fan shutting down.

Gordo must be from the area if he knows about Point Bock!

I prefer the Honey Lager!

Looks like Gordo's from the Southwest :cool: Must be a Wisconsin transplant :2: :2:

Who else who appreciate such fine beverages. :D

It does kinda sound like the fan shutting off. It's been in the 90's here lately and it's probably been running. It was a lot cooler today and didn't seem to hear it. That must be it! :4:

Transplant

Not a transplant but my wife's from Mosinee (great area of the state). Was just back there vacationing a week ago. We go there to get out of the heat. You definitely have a fun state to live in and the people are great! Point Maple is not bad either. ":7:

Love your state's tourism motto: "Come to Wisconsin and smell our dairy air! :22:

It's coming from the Intake

I have this on my '95 Civic. If you listen closley under the hood while someone else turns off the truck, you will hear it coming from the air filter. I really can't explaine why it happens for sure, but I think the pistons might be still moving/slowing down, after the ignition is turned off. So you won't have the sound of the motor because there is no spark, however the internals are still in motion and so the engine is still sucking in air. Like I said my Civic has done this for 7 years, I have had no problems with the car(I mean none -in seven years- thats another story). Anyhow, I havent noticed it on my Pilot but I will check. You could have the dealer check it out and maybe they can explain it better. Hope this helps a little.

Re: It's coming from the Intake

Possible, but extremely unlikely that there is air moving IN more than a fraction of asecond or so after ignition is off. There is just too much friction (even in the excellent Honda engine!!) for there to be motion for more than a moment. Further, the throttle blade is CLOSED when you let off the gas pedal, so that air would have to be "pulled" past a steel-on-steel seal-- if that was the case when the car was RUNNING you'd have horrible throttle response, as air would always be leaking past...

More likely the electric fan... Possibly some other pump/system under hood also cycles off after ignition killed...
