    Thanks for all the info. It does sound odd for sure. Glad smog pump is all it is. Would be nice if they put that in the manual since they disclose the other noise it may make. This noise is far more obvious. Gonna love this forum!

    Just got similar experience. Thanx for the answers from this thread. Looks like am gonna disappoint the mechanic when I go back next day when a check will be made by my local dealer mechanic. They weren't too honest the first time when they heared it or they are just unqualified.....:p

    Funny, I never new my 12 had a smog pump and it being 2012 and all this high tech mumbo jumbo bs is out I am very surprised they are still using the god given air pump. I really don't like these things.

    Yeah you figure these ancient things would stay out of the newer vehicles by now. I am personally pissed about that!

    I noticed this same noise the day I brought my new 13 home a few months ago and reported it to the dealer. I ended up putting in a formal complaint with Toyota corporate and they sent out a factory rep to listen to the noise. The rep acknowledged the noise and confirmed it was the air pump but stated it was not a safety concern. I expressed my dissatisfaction that a new truck should not be making a sound like this. He noted my complaint and stated that if Toyota decides to do anything about, they would be in touch. Basically they won't be doing anything in less enough customers complain. I kinda wish I bought a 12 instead of a 13 now.

    Hmmm... I think Toyota is recall/campaign sensitive, don't you?! ;)

    Same sound on my 13' with 113 miles. Wondering if this goes away or dissipates over the course of the break in period? Very unpleasant sound. Sounds like a violent spool down and click.

    Is Obama in my truck? Robbing power? Thinking of taking a hacksaw to the smog pump.

    Any other "surprises" for a lurker that is kicking himself for not popping on a 12'?

    Was worried about the noise at first, and dealer thought something was terribly wrong with the truck...after talking to a tech, they printed out the info on the smog pump or whatever it is. It is a normal sound, and will not disappear over time.

    Here is the noise...

    Not sure if this is the same thing cause we are talking about two different vehicles but the Air Reaction pump quit working on my 07 4Runner, serves the same purpose as described about blowing air across the cat...just the part itself is $1,251.26. Apperantly if that part goes bad your cat can go bad which is also the case in my 4runner. I'm sure there's more to it than just that just throwing it out there.

    I picked up my '13 Tacoma with 157miles on Sunday. I heard the same noise most have been experiencing. I immediately called the dealership letting them know the issue but was assured it was normal. Good to hear it's not a major problem (yet).
