Don't worry about it. It's been in the design phase for years.

Mine has it too. Also from in the cab it has a more zzzzzzzzz sound. It's been there since day one for me. Must be normal.

It's not a '12 thing. Mine does it too.

Maybe your smog pump is broken.

I was wondering the same thing. I keep thinking I have a 4cyl not V6.

Yeah that noise is kinda annoying.

It is normal and is emissions related. Our '12 RAV4 and '13 Taco do this....as did our '10 Yaris.

Same here.

I've owned a lot of trucks and Jeeps.

I traded my 2010 JK last year, which DID lack power.

I can't comment as to whether the Pentastar fixed that, since I haven't driven one.

My 13 does the same thing. Sounds like a blender or coffee grinder turning off. I'm hoping the sweet sound of the TRD SC's whine will help me not notice the coffee grinder sound every time I turn my Taco off. Sure hope TRD hurries up with the 13 kits.

area 52

I traded a 09 Rubicon in on my 13 taco and to say the JK's lack power, and this is coming from a many time "jeep" lover, has to be the worlds largest underestimate. I think you have to have some power before you can have a lack of power. I truly miss my Rubi but OMG was she a gutless turd. The 3.7 JK's have a lot better power.

Thumbs up Strange noise in engine when shutting down 2013 Tacoma

Thank you for all the information. I have been giving my husband heck over the weird noise every time I shut the truck down (mileage under 3000) in the garage. I don't remember hearing it when the truck was first brought home or at the dealer. I'm still going to note it with the dealer because it is disconcerting but I won't be a b.... about it as much since so many seem to be experiencing it.

Welcome to TW!

Sounds like you have the right attitude about it. I don't mind the noise, but for people that do, I think it's appropriate to mention it to the dealership. That's the kind of feedback that may not directly benefit the owners of current vehicles, but may lead to design changes for future models.

There's already a very small intake muffler on the pump. Changing it to a more capable muffler may descrease the noise level, as would insulating the pump, and/or lining the underside of the hood with sound deadening material.

I am a technician and I just picked up my 2013 trd. It's has 250km on it and I have also noticed this noise it almost sounds like rushing air followed by a faint backfire or popping noise. I am kinda surprised this is normal though but glad it is a "normal noise"?

Does it sound like this?

If so, that's not normal.

Mine made that noise, and also had a burning rubber smell. The burning smell went away at 1500 miles and the sound is still there. Guess they're not related!
Thanks for the info.

Not sure about the rubber part, but new exhaust and engine parts can take some time before they stop smelling.

My 2013 DCLB limited does the same thing. Tech here at the dealership said it is normal and it is the air pump for the emissions system. I tried some other Tacomas here on the lot and they all do it to some extent.

DAC (Downhill Assist Control) is automatically deactivated with any throttle or brake input from the driver. I think you meant VSC.

I think my tacoma has great power for a v6. I have owned a bunch of trucks and this thing gets up and goes. When I first drove it home with 1 mile on it, it did seem a bit on the conservitive side. But over time it seems to run awesome. Probobly just me but I love the 4.0

Yep... Mine does the same thing every time I turn it off. First place I came was here and there was the answer.

As of right now it is sitting in the garage making the Fuel Emission noise from underneath but that is completely normal too. Freaked me out the first time I heard that also. The interwebs are a amazing tool.
