    Had always wondered what the whine was. I always thought it was a harmonic coming from the rear of the truck. Its most noticeable when towing and in the summer, so the A/C makes sense. Anyhow, since my warranty expired last year, its moot.

    Built at the end of July, took delivery last Friday, have TSB from January... The thought of a dealership ripping out the dash on a truck with less than 1k miles on it is disappointing. At least it wasn't the rear diff so I got that goin' for me, which is nice.

    Apologies if I am repeating a similar question. I have a 2010 TRD Sport with 170K miles, at speeds ~60 mph I get a higher pitched whining (similar to the wine glass) that is completely dependent on the accelerator. If I take my foot off the accelerator, the noise instantly stops. When I press the accelerator it instantly returns. It also happens at lower speeds (20-30 mph), but does not seem to be related to RPMs.
    Thanks for any suggested paths to search.

    Exact same experience. Got to dealership to pick up the truck they were holding for me, also built end of July, 3 miles on odometer and less than one mile into the test drive it makes this whistle sound that I hear 2 or 3 times during test drive. Almost walked away when salesperson gives some BS about ia break-in noise that will go away after a few miles. But before I walk, I pull up TW on my phone, search for whistle sound and find this page. Long story short, I have a new Taco knowing it as a quirk of the truck that, already two weeks later, I hardly notice anymore. I’ll re-evaluate at the 5k service and mention the TSB if it becomes annoying.

    That is exactly what I am hearing in my 2019 SR 5 4x4. I’m at 60k now and just started noticing it, but I am driving on and OR every day now in a new job. Basically what I am hearing is this is “normal” for the 3rd gen? Anyone have any luck fixing it or is it just what it is?

    I have an 06 4R that has the Toyota whine.

    Now I have a 22 Taco with the Toyota whine.

    Just lets me know when something is or isn't engaged tightly in an unknown mechanism.

    The 06 started when relatively new and has never gotten worse.

    I was kind of proud when the little Taco started whining.
