Squeaking sound from engine bay???

2018 TRD Sport 4x4 DCSB with 30k miles. I noticed a squeaking sound starting at 2k RPM and increases frequency with more RPM. It happens when moving and when parked. It appears to be coming from the front of the engine bay, so I'm thinking belt noise?? I should note that I can't consistently reproduce the noise so I'm trying to avoid a trip to the dealership. I guess I could record the noise for the tech to hear if it doesn't happen when at dealership. Has anyone else experienced this? Thanks all!

 

Serpentine belt, happened to mine. Toyota is aware of belts prematurely wearing. Had mine replaced and the problem went away.

 

30k miles of mostly highway driving and my belt is worn? That's ridiculous. Is there a TSB or something I can reference when I call the stealership?

 

Mine started at 20k if it makes you feel any better. There is a bulletin for it, ill try to find it in a bit. It's not a recall so they won't do anything unless you request it.

 

Heres the thread, the tsb link is on the first post...

Argh. Thanks for finding the bulletin. TW is the best!

 

I had the issue since 20k and could never duplicate at the dealership. The warranty is good for 36k. I was able to duplicate it and showed the tsb and they honored my replacement at 40k.
