Sound coming from under engine


Topic starter

Hey scotty 2019 grand Cherokee 5.7 23k miles. When my car is idling I hear a growling sound that comes and goes almost like when the belt is spinning and when it comes to a point it makes the sound and then goes away. What could it possibly be?

Here’s a video of the sound if anyone can please help me out for a possible diagnosis.

High pitch noise or deep noise? Can be belts or pulley. My subaru started with a slight noise every now or then.then over 3 months it was a low but constantly whining then got louder it ended up being a bearing for my alternator pulley.

Dirt got into my engine bay muddy roads and over time it became an issue

Surely it’s too soon for any of the pulleys to already be worn. But anyway, see here for  diagnosis - 

Don't call me Surely. @itwt, never overestimate the quality of Chrysler Corp. parts. 23K miles sounds about right for their stuff.
