    I'm getting a squeak/whiny noise during acceleration on my brand new tundra. Loudest around 2000rpm. There's no noise when in neutral and stepping on the gas, and no noise when coasting. It's driving me nuts. I plan on taking it in when I have time but I have no idea what the noise could be when there's nothing worn down or needing replacement after only a couple thousand miles.

    I have the same...usually underway. Sounds like a rubber bushing being compressed.

    Dealer says it's the throttle body and it's magnified "10x" by my k&n air filter. My buddy has the same filter on his tundra and doesn't get the noise which is odd, but I guess there's nothing I can do.

    Oh, I just dropped in a KN filter as well. and yes, getting a subtle whistling sound, like a window is just barely cracked open. That's a whole different squeal that blends in perfectly with the tinitus

    I have the same issue with my new Tundra. At first it was very subtle but I have about 6,000 miles on my truck and it has gotten worse. I took it to the dealer and a service technician rode in it with me. He heard the noise but couldn't explain what caused it. I intend to take it back to the dealer when I have time but it won't be soon unfortunately. Honestly I can't stand the noise. Let me know if you find out what the cause of the noise is.

    Apparently it's normal according to Toyota techs, and mine was worse because I have a k&n filter in there. Swapped the oem in and it was quieter but yea still there.

    What if you didn't add a high flow air filter?

    The whistle comes from the air flow over the throttle body blade when it is at the correct angle (throttle position). The screen that is shown in the link disturbs the laminar air flow prior to reaching the TB blade. It's similar to when you take a blade of grass between your thumbs and blow across it just right to make it whistle.

    I noticed only after installing my TRD cai. Couldn't figure it out. I took it to the dealer, had a mechanic drive with me, and he heard it clearly too. After an hour of looking for the sound and trying to replicate it in the garage, the mechanic couldn't find the cause. But, he did go the extra mile and drove a new stock Tundra to see if it made the sound. He took me for a ride and we both had to listen carefully, but I heard the same sound, only very faintly. I'm no mechanic, but it seems the sound is amplified with more air being allowed to enter the throttle body. Found the solution on this forum, problem solved.
