2024 Engine Chirp

Took it into the dealer for service and of course while I am there the shop foreman rode with me and the sound could not be replicated. Went out this morning and of course it is back and pretty consistent. No check engine lights are present more of an annoyance on a brand new truck with 4,600. Anyone else run into this yet and what the remedy is? I only really hear it between 2-3k rpms and it does not seem to go away when the engine warms up.

Sounds like its coming from something on the serpentine belt loop. Could be idler pulley bearings or one of the accessories.

Increase with RPM's?

as @aFallenTree it sounds like a accessory on the belt.

 

[nick71692]

It does not increase with RPM or get higher. It's most prevalent between 2-3k rpm

Even just a dirty or wet serpentine belt can squeak like that. It’s nothing I would be terribly concerned about at this moment.

Ended up diagnosing to be an idler pulley. For good measure they replaced both, also the belt tensioner and the main belt. So far so good.
