Noise above 30mph

[Reyneon]

Anyone else have this happening with your new 4Runner? I only hear this sound when the weather is warm and above 30mph. I’ve been to the dealership twice and they cannot find the cause/issue.

YES!!! Been to the dealer twice for this and they claim they can’t hear it. Been driving me nuts since day 1 and no one knows what it is. I put some microphones around the 4R while driving to try and narrow it down (I'm an audio engineer), and it sounds like it's coming from the front left wheel well or just on the other side of it in the engine compartment. It doesn't get louder or change pitch with speed or wind increases, and like you said it's more prevalent when it's warm out or I've been driving awhile.

We've been talking about it a bit more here too:

Hopefully someone can figure out what exactly is causing this, super annoying! Looks like there's some 6gen Tacoma owners with it also, few videos on YouTube about it.

My dealer said they won't look into it again until the parts for my brake squeal come in, in case that's causing it.
