Hi, I have a 2016 Suburban with ~93k miles. Recently, a noise started with the vehicle and need some help determining what the noise is.

Here is a link to the video:

Thanks for any input here.

 

Not much activity on this site

Could be a belt. Was the AC on?

 

Yes AC was on.

 

Could be the serpentine or a tensioner. Just spit-ballin' here.

 

Ya I am leaning that way as well. Appreciate the input. Hopefully will get to deal with it soon. Intermittent at this point.

 

Belt or pulley noise would do it when stopped and idling. HIgh pitched noise when driving could be the brake pad wear sensors letting you know it's time for new pads.

 

…we are due for brakes as well. I have not heard the noise when idling so thanks for that thought.

 

Following up. I switched out the rotors and brake pads and the noise has disappeared.
Thanks again for your help here.
