Intermittent buzzing sound

[timetoclimb]

Totally agree. I pushed the tech on what’s causing it and they said everything checks out. At least I have it documented incase something else goes on.

haha I hear that, I almost left the dealership with new tire and wheel set up but decided I didn’t wanna get chewed out again haha.

I made another thread on this issue not realizing you had posted this. Mine makes the exact same noise under the same conditions. At least we know we’re not alone in the issue, or perhaps it’s normal. Would be good to get some clarity on it. Kinda annoying when trying to drive windows down

yea I agree it’s kind of annoying with the windows down. I still can’t help but think it’s not normal but I guess time will tell as more people get these trucks. If I find anything else out I’ll update this thread.

Got my 4R a few weeks ago and have 730miles, and love it so far. But when driving I hear a buzzing like noise when the windows are down, that’s coming from the engine bay.
it’s there on slight steady throttle but goes away when accelerating or off the pedal.
it sounds almost electrical buzz or crickets.
anyone else experience this or have an idea what’s it could be? Thought maybe a wastegate issue? Thanks!

I recently bought a 4Runner and only have about 300 miles on the odometer. I’m already hearing a humming noise, even with the windows closed. Are you guys still experiencing it, or has anyone found a fix?

I test drove one the other day, I though I heard a high pitched humming sound. Is that the turbo?

I heard that too. Pretty sure it’s the turbo making that sound.
